Survey study 61 Cohort study 13 Case-control study 13 Study 13 Randomised trial 9 Systematic review 5 Systematic review, 2026 Does the menstrual cycle affect athletic performance and fatigue in female athletes? Lab tests showed stable athletic performance across the menstrual cycle, but the premenstrual phase linked to higher fatigue. In real games, athletes covered less distance during menstruation with separate thinking changes. Cohort study, 2026 Does sleeping longer improve mood and fitness in elite athletes? Yes. Sleeping longer was linked to better mood and fitness across all athletes, regardless of menstrual cycle status. Sleeping less than 8 hours was linked to below-average mood and fitness. Systematic review, 2025 Are PMS and PMDD more common in highly trained female athletes than in women who don't train intensively? Female athletes had somewhat lower PMS rates and somewhat higher PMDD rates than non-athletes, but neither finding was statistically significant. We cannot be confident in these findings. Systematic review, 2025 Do different types of exercise help with PMS? Yes, multiple types of exercise including aerobic exercise, yoga, swimming, and stretching all reduce PMS symptoms. Case-control study, 2023 Does the serotonin system work differently in PMDD across the menstrual cycle? Yes. Women with PMDD showed an 18 percent increase in serotonin transporter binding during the premenstrual phase while controls showed a 10 percent decrease. This increase correlated with depression severity. Systematic review, 2023 How common are menstrual cycle problems and PMS or PMDD in female athletes? Menstrual cycle problems are common in female athletes, with dysmenorrhoea affecting about 32%. More athletes report symptoms during their period than in the days before. Systematic review, 2022 Do athletes' feelings and performance change across the menstrual cycle? Some feelings change across the cycle, especially motivation and mood. However, the research methods vary a lot, so we cannot be very confident about most findings. Survey study, 2026 Does stress affect premenstrual symptoms in female athletes, and can coping strategies help? A review of research found that higher stress worsens PMS symptoms in female athletes, while healthy coping strategies like emotional regulation and social support can reduce symptoms. This comes from multiple studies rather than one new study. Cohort study, 2026 Does the menstrual cycle phase affect how much physical activity women do? No. In active women, daily physical activity remained stable across all menstrual cycle phases (around 50 minutes per day), even when premenstrual symptoms were present. Cohort study, 2026 Does sleep change during different phases of the menstrual cycle? Yes, women's sleep is disrupted during menstruation and the pre-menstrual phase of their cycle, though they often don't notice it happening. Study, 2026 Does the menstrual cycle affect athletic performance, recovery, or sleep despite hormone changes? Hormone levels change significantly across the menstrual cycle and symptoms are higher at certain times, but athletic performance, recovery, and sleep remain consistent in trained women. This is a well-designed study. Survey study, 2026 How does menstruation affect girls' participation in organized sports? Most girls reported that menstruation affected their sports performance and attendance. About 91 percent noted skill changes, 77 percent effort changes, and 58 percent attendance changes. Fatigue, mood, and pain were most common, and 18 percent were worried enough to consider quitting. Survey study, 2025 Do mental abilities like reaction time and attention change across the menstrual cycle? Yes, some do. Women had faster reaction times and fewer mistakes during menstruation, but slower reactions and poorer timing skills during the luteal phase. Cohort study, 2025 How do menstrual cycle phase and birth control type affect sleep and training readiness? All female endurance athletes reported higher symptom severity during bleeding days and lower sleep quality and training readiness before menstruation, with some differences by birth control type. These patterns held for both pill and non-pill users. Study, 2025 Does the menstrual cycle affect sleep, energy, and injury risk in young female athletes? Yes. Young female athletes reported worse sleep and more tiredness during the luteal phase, particularly the week before their period. They also had more injuries during these phases. Randomised trial, 2025 Does whole-body cryostimulation improve sleep quality in female athletes during different menstrual phases? Yes, whole-body cryostimulation improved sleep quality and reduced fatigue during the mid-luteal phase, when sleep naturally worsens. It did not help during other phases. Survey study, 2025 How common is PMS in adolescent female athletes? PMS was present in 16.33% of adolescent female athletes. Rates varied by sport, with karate players having the highest rate at 25% and sprinters having the lowest at 12.12%. Survey study, 2025 Do female athletes have lower PMS than female non-athletes? Yes. Female athletes had noticeably lower PMS and night eating syndrome compared to female non-athletes. Survey study, 2024 Can period-related symptoms predict whether female cyclists manipulate their periods? Reduced ability to tolerate workouts predicts menstrual manipulation among Australian cyclists, but specific symptoms do not. This is moderate-strength evidence. Study, 2024 How does menstrual cycle phase affect sleep and recovery after exercise? Sleep quality was worse during the luteal phase (the second half of the cycle) than during earlier phases, with women waking up more and sleeping less deeply. Recovery feelings and muscle soreness were not affected by cycle phase. Randomised trial, 2024 Does a banana drink with egg white reduce PMDD symptoms and improve mood? The banana drink significantly reduced anxiety, fatigue, concentration problems, insomnia and physical symptoms, and improved mood. Serotonin levels did not increase significantly. Survey study, 2024 Are calorie tracking and eating disorders linked to menstrual problems in female athletes? 64.6% of resistance-trained athletes tracked calories. Limited connections appeared between body image concerns or eating disorders and menstrual cycle problems. However, there was a clear link between eating disorders and missing periods. Survey study, 2024 Are menstrual cycle symptoms related to sleep problems and mental health in female athletes? Yes. Women with more menstrual symptoms reported more depression, anxiety, stress problems, and sleep issues. Survey study, 2022 Do female athletes get enough knowledge and support about their period? No. Most lack knowledge and rarely discuss menstrual health with coaches. 81% said it is taboo in sports. Survey study, 2022 Do menstrual cycles and birth control affect female athletes' training and performance? Most female athletes experience menstrual symptoms like period pain and premenstrual syndrome that affect how they perceive their performance. Only 18% plan their training around these issues. Survey study, 2021 Does the menstrual cycle affect women's ability to train and compete? Yes. Women who experienced more frequent menstrual symptoms were significantly more likely to miss or change their training, miss competitions, miss work or school, and use pain medication. Study, 2021 How does the menstrual cycle affect sleep in female athletes? The menstrual cycle appears to affect sleep in female athletes, changing both the amount of sleep and the types of sleep stages across different phases of the cycle. Study, 2021 Does exercise affect a woman's balance more during the premenstrual phase? Yes. Women had lower balance during the premenstrual phase before exercise, and their balance became more unstable after exercise during this phase compared to other times in their cycle. Cohort study, 2020 Does sleeping longer help teenage athletes experience less PMS interference with sports? Yes. Teenage girls who sleep longer in one year are less likely to have PMS symptoms interfere with their athletic performance the next year. Study, 2020 Does sleep quality change between the first days of the period and mid-cycle? Yes. Female athletes slept less, took longer to fall asleep, and had lower sleep quality during the first 2 days of their period compared to mid-cycle. Women concerned about sanitary products had even less deep sleep. Survey study, 2020 Do athletic students have less PMS and period pain than non-athletic students? Athletic and non-athletic students have similar rates of PMS. Nearly all students in both groups experience period pain. Athletes reported somewhat more pain intensity than non-athletes, but the overall PMS severity scores were similar between groups. Case-control study, 2020 How does competitive sports affect PMS, PMDD, and menstrual disorders in young female athletes? Female athletes had significantly more PMS (49.33%) than non-athletes (32%), with the risk increasing by 1.71 times per year of age. PMDD rates were similar between groups, but athletes had heavier periods and longer breaks between menstruation. Survey study, 2019 What lifestyle and sleep habits are linked to PMS in teenage girls? In Japanese high school students, poor sleep quality, long internet use, skipping breakfast, and not playing sports were linked to higher PMS risk, with menstrual pain being the strongest risk factor. This is observational so we cannot be sure these habits cause PMS. Cohort study, 2019 Do young female athletes have more menstrual problems and PMS than non-athletes? Yes. Intense exercise before first menstruation delayed when girls got their period. Competitive sport increased risk of PMS and PMDD. Cohort study, 2018 How common is PMS in female athletes across different sports and ages? PMS is extremely common in female athletes. Most had at least one type of symptom, and many had both physical and psychological symptoms. Younger athletes had especially high rates. Case-control study, 2017 What lifestyle factors are linked to premenstrual syndrome in teenage girls? Four lifestyle factors showed clear links to PMS: less exercise, higher body weight, more salty foods, and more sugary foods. Study, 2017 Does regular sports help prevent PMS in high school students? Yes. Students who did regular sports had significantly lower PMS levels than students who were sedentary. Cohort study, 2015 How common are PMS and PMDD in young female athletes? PMDD affects about 8% of young women regardless of sport. PMS is significantly more common in athletes (49.33%) than non-athletes (32%). Case-control study, 2010 Is a gene variant linked to PMDD? No, this particular gene variant was not associated with PMDD. This does not rule out other genetic factors or that PMDD has a genetic basis. Survey study, 2009 Does PMS affect sports performance in female athletes? About half of female soccer athletes (47.32%) had PMS, and those with PMS felt their sports performance was noticeably affected. Athletes with more symptoms reported greater impact. Case-control study, 2006 Are irregular menstrual cycles linked to eating disorder risk in female athletes? Yes. Female athletes with irregular cycles had higher eating disorder risk than athletes with regular cycles. Non-athletes showed no such link. Cohort study, 2006 Are specific genetic variations linked to PMDD? No. This study found no significant association between eight common genetic variations in serotonin pathways and PMDD, suggesting these particular genetic variations are not major contributors to PMDD. Randomised trial, 2001 Does hormone replacement therapy change serotonin receptors in postmenopausal women? No significant change was found in serotonin transporter or 5-HT2A receptor binding with hormone treatment in healthy postmenopausal women, though depressed women showed a more pronounced effect. Study, 1995 Do women who exercise have fewer PMS symptoms? Yes. Women who exercise regularly experience better mood and fewer symptoms before and during their period compared to sedentary women. However, competitive athletes did not show this benefit. Survey study, 2026 Does the menstrual cycle affect how well female athletes perform? Yes. Athletic performance is best after menstruation and after ovulation, with sprint times improving by 7.5% and jump height improving by 5.1% in these phases. Performance drops during the premenstrual phase, with acceleration slowing by 2.3%. Randomised trial, 2026 Does caffeine improve athletic performance differently at different times in the menstrual cycle? Caffeine (400 mg) improved alertness and reaction time across all menstrual cycle phases, but effects on muscle and power were less consistent and didn't clearly depend on cycle phase. This was a small pilot study in 12 trained women. Survey study, 2026 Does PMS affect emotional performance and body awareness in female athletes? Yes. Women with PMS had significantly worse emotional performance scores than those without PMS, and greater PMS severity linked to lower body awareness and worse performance mood. Study, 2026 Does menstrual cycle phase affect how the brain reacts to heading a ball in female footballers? Menstrual cycle phase does not change how the physical force of heading affects the brain, but the brain's thinking ability does change across the menstrual cycle. This was a small proof-of-concept study. Interview study, 2026 How do parents talk to their teenage daughters about starting their period? Parents experience emotional challenges discussing menstruation with their daughters. Cultural attitudes that treat menstruation as taboo shape these conversations, and gender roles affect how openly families discuss it. Survey study, 2026 Do premenstrual symptoms affect athletic performance? Yes, women with premenstrual symptoms showed higher stress and anxiety, and athletic performance was best during ovulation. However, this is a small feasibility study with only 18 women who had actual performance testing. Survey study, 2026 Are PMS symptoms and injuries common in teen girls who play competitive badminton? Yes, in this small study most of the young badminton players had at least one PMS symptom, and about one in seven had a knee or back injury linked to the sport. Playing badminton for longer was linked to more PMS symptoms, but this study cannot prove that badminton causes PMS. Randomised trial, 2026 What types and amounts of exercise help or harm PMS? Regular moderate aerobic exercise and yoga reduce PMS symptoms like pain, fatigue, anxiety, and low mood. However, very high-intensity training combined with insufficient food can worsen menstrual health. Survey study, 2026 How common is PMS among female athletes in Hong Kong? 47.7% experience moderate to severe PMS. Physical symptoms like fatigue, cramps, and bloating are very common, affecting 60-77% of athletes with these symptoms. Survey study, 2025 What are menstrual cycle patterns in elite female basketball players? Most (78.51%) had regular cycles averaging 27.69 days. Most (86.84%) experienced period pain, and 77.63% had PMS symptoms. About 22.81% experienced absent periods. Randomised trial, 2025 Does dark chocolate help exercise performance and muscle pain during the premenstrual phase? Dark chocolate significantly improved exercise performance and reduced muscle soreness during the premenstrual phase in female CrossFit athletes. The study was very small and limited to trained athletes, so results may not apply broadly. Survey study, 2025 Does the menstrual cycle affect fitness performance? No. Women with mild period-related symptoms performed similarly on fitness tests across all phases of their cycle, whether they trained regularly or not. Survey study, 2025 Is exercise addiction linked to severe PMS in elite female athletes? Yes, elite female athletes with higher levels of exercise addiction had more severe PMS. Nearly all athletes (94.4%) reported severe PMS. Survey study, 2025 Do menstrual cycle phase and symptoms affect sleep in female footballers? Menstrual cycle phase alone did not affect sleep. But more menstrual symptoms were linked to later bedtimes, longer total sleep, and more time awake. Survey study, 2025 Do hormone levels during the menstrual cycle affect sleep in female athletes? Hormone levels (estradiol and progesterone) themselves do not affect sleep. But having more menstrual symptoms was linked to worse sleep in naturally cycling athletes. Survey study, 2025 Does the menstrual cycle affect recovery after football matches? The menstrual cycle has limited effect on how female footballers feel after matches. Perceived recovery may be slightly worse during menstruation, but overall no clear differences were found between cycle phases. Survey study, 2025 Does PMS affect how well female martial arts athletes perform? Yes. Most female martial arts athletes experienced severe PMS symptoms, and PMS significantly affected their sports performance, though most still achieved adequate performance levels. Survey study, 2024 What premenstrual symptoms do martial arts athletes experience? Martial arts athletes experience both disturbing and non-disturbing PMS symptoms with regular 35-day menstrual cycles, and they have no significant difference in PMS compared to non-athletes. Survey study, 2024 Are anxiety and depression linked to PMS in female athletes? Yes, the study found strong links between anxiety and depression with PMS in female athletes. However, this is a small study from one location, so findings may not apply everywhere, and showing a link doesn't prove one causes the other. Survey study, 2024 Do sports activities reduce PMS symptoms and improve mood in young women? Mood swings were significantly better in sports students (more positive) than non-sports students, but PMS symptoms showed no significant difference between the groups. This is low-strength evidence from a small observational study. Lab study, 2024 Do physical exercises help women in their 40s and 50s improve strength and flexibility? After 12 weeks of regular exercise (two 60-minute sessions per week), women showed improvements in abdominal strength, hamstring flexibility, and upper body strength. Squats and push-ups were particularly helpful. Survey study, 2024 Do athletes understand their menstrual cycle and how it affects their performance? Most athletes feel their menstrual cycle affects their performance, but most cannot correctly identify the different phases. Many feel tired or unmotivated during certain phases. Survey study, 2024 Does the menstrual cycle affect well-being and performance in professional female soccer players? The menstrual cycle phase did not affect how far players ran, how hard they worked, or their overall well-being after matches. Sleep quality was worse after away matches, and losing affected stress and mood for 2 days, regardless of cycle phase. Study, 2024 Do women with PMDD have different patterns in genes related to brain chemistry? Yes. Women with PMDD had lower activity of a specific gene (KCC1) related to brain chemistry during certain parts of the menstrual cycle. This supports the idea that PMDD may involve problems with how a calming brain chemical called GABA is controlled. Survey study, 2024 How does menstruation affect female taekwondo athletes' training and performance? Physical premenstrual symptoms and menstrual cramps most affected athletic performance. Menstruation did not stop athletes from competing, but weight loss before competition was common and linked to irregular periods. Survey study, 2023 Does low energy availability or eating problems affect how well young female soccer players perform? No. Low energy availability and eating problems were not significantly linked to physical performance. However, most players perceived their menstrual cycle affected their game, and they rarely discussed this with coaches. Randomised trial, 2023 Does matching your running training to your menstrual cycle phase improve performance, recovery and wellbeing? This pilot study was designed to test that question, but the text available here stops before the results section, so no answer can be given yet. Survey study, 2023 Do PMS symptoms affect how female athletes train and perform? Yes. Women with severe PMS were much more likely to change their training schedule. All women reported performance dropped during and before menstruation, with bigger drops in those with severe symptoms. Randomised trial, 2023 What does research show about PMDD neurochemistry? The provided text does not include results from a PMDD neurochemistry study. It discusses unrelated research on other topics. Cohort study, 2023 How do menstrual cycle and birth control pill phases affect female athletes' training and performance? Female rowers performed better in the middle of their cycle and worse during their period and premenstrual phase. Those taking hormonal contraceptives also performed better when taking the pills. Case-control study, 2023 Does micronutrient intake differ between female athletes with and without PMS? Most nutrients showed no clear difference. Lower vitamin D intake tended to be associated with PMS, but this finding was not definite. Randomised trial, 2023 Does a smartphone app for heart rate variability biofeedback reduce premenstrual and depressive symptoms? Yes, the app reduced premenstrual, depressive, and stress symptoms over 4 weeks. However, it did not change the underlying heart rate patterns it was designed to improve. Study, 2023 Does martial arts exercise reduce PMS? Yes. Female students who did more pencak silat exercise had lower PMS symptoms, but this is based on students who already do martial arts, so we cannot be certain it causes the improvement. Interview study, 2022 How does the menstrual cycle affect female footballers' on-field performance? All elite female footballers perceived their menstrual cycle to harm their performance, most severely during menstruation and the days before it. Survey study, 2022 How do female elite athletes cope with premenstrual symptoms? Strategies that help include being aware of symptoms, practicing self-care, and communicating with others. Strategies that don't help include trying to avoid harm and adjusting energy. Premenstrual symptoms reduced physical ability and well-being. Survey study, 2022 Does exercising regularly stop PMS symptoms in students? In this small study, students who exercised regularly did not have fewer PMS symptoms. In fact, PMS was more common among those who exercised regularly, but this study cannot show that exercise caused it. Survey study, 2022 How does competitive swimming affect menstrual cycles and PMS symptoms? 31% of competitive swimmers experienced menstrual cycle stoppage for over 3 months. More intense swimming predicted worse cycle problems, but maintaining a healthy body weight protected against disruptions. Swimming did alleviate some PMS symptoms. Survey study, 2021 Does what elite young female athletes eat affect their menstrual cycles? Yes. Athletes who ate enough carbohydrates did not have menstrual problems. This suggests that adequate calories and carbohydrates may help maintain regular periods. Interview study, 2021 How does the menstrual cycle affect elite athletes' training and competition? Elite athletes with natural menstrual cycles reported physical symptoms, mood changes, and reduced motivation to train. Many chose to control their cycle to reduce its effects on competition. Survey study, 2021 Does regular exercise reduce the severity of premenstrual syndrome in teenage girls? Yes, there was a relationship between regular exercise and less severe PMS. Girls with regular exercise had lower rates of moderate and severe PMS than girls with irregular exercise. Survey study, 2021 Do athletes have fewer menstrual and premenstrual symptoms than less active women? Yes, athletes had fewer physical and mental symptoms during both menstrual and premenstrual periods compared to active and sedentary women. Survey study, 2021 How common is PMS among female athletes and what causes it? 14.5% of elite female athletes met PMS criteria and reported high rates of fatigue, anger, and muscle pain. The study found no clear links to training intensity, body weight, diet, or other factors investigated. Survey study, 2021 Are stress, eating habits and exercise linked to PMS, and does knowledge matter? Stress, eating patterns, and exercise patterns were all linked to PMS, but how much a girl knew about PMS was not linked to whether she had it. Survey study, 2021 Does managing stress, emotions, diet, exercise and sleep help PMS in female athletes? Yes. Stress response directly affects PMS, and managing emotions well, eating well, exercising and sleeping enough are connected to lower PMS. Survey study, 2021 Does PMS affect jump performance in female athletes? Female athletes with breast tenderness (a PMS symptom) showed reduced jump height during the luteal phase compared to those without this symptom. Overall, there were no major differences in jump performance across the menstrual cycle. Survey study, 2020 Does the menstrual cycle affect how fast female athletes run? The study found no clear difference in running speed between the follicular and luteal phases. Running times slowed on menstruating days compared to non-menstruating days for most athletes. Lab study, 2020 Can Paeonia lactiflora extract reduce anxiety in rats with PMS-like symptoms? Yes. In rats with PMS-like anxiety, Paeonia lactiflora extract reduced anxious behavior and changed three brain chemicals involved in stress and mood. However, this is a rat study, so it does not directly show whether it would help people. Interview study, 2020 How does the menstrual cycle affect female elite athletes? Most athletes reported menstrual symptoms that they felt harmed their performance. Two-thirds took medication to try to feel better during their cycle. Review, 2020 Can not eating enough or overexercising stop your period? Yes. Between 16% and 47% of lean female athletes have disordered eating. Low energy, excessive exercise, and stress can stop periods, but periods usually return when these causes are addressed. Survey study, 2020 How common is PMS in elite female athletes, and do training or lifestyle factors cause it? 14.55% of elite female athletes have moderate to severe PMS. No specific modifiable risk factors were found. 76.6% of athletes felt their symptoms interfered with performance, but only 5 out of 18 athletes with PMS saw a doctor. Interview study, 2020 Does the menstrual cycle phase affect athletic performance and decision-making? Yes. Physical performance was better during the menstrual phase than other phases of the cycle. How impulsive athletes were varied by cycle phase, but risk-taking did not. Athletes on birth control pills showed larger performance changes. Study, 2019 Does 8 weeks of aerobic exercise reduce PMS symptoms? Yes, aerobic exercise for 8 weeks reduced both psychological and physical PMS symptoms with a clear difference between before and after. Case-control study, 2019 Does inflammation affect mood in women with PMS? In female soccer players, those with PMS had higher levels of inflammatory markers and reported more depression and tension at certain cycle phases compared to those without PMS. Survey study, 2018 How does intense karate training affect the menstrual cycle in young female athletes? Most young karate athletes had menstrual disruptions like PMS or painful periods, likely caused by intense training. Survey study, 2018 Does plant protein in the diet help prevent PMS from affecting athletic performance? Possibly. Athletes whose PMS affects performance ate a lower proportion of plant protein compared to animal protein, though total protein intake was the same. Survey study, 2018 Does equol production status affect PMS symptoms in female athletes? Women who couldn't produce equol from soy were 3.34 times more likely to have poor athletic performance from PMS symptoms. But this is a small study in Japanese athletes only, so results may not apply widely. Study, 2018 Does regular exercise increase hormones that help with PMS? Yes. Regular exercise significantly increased melatonin levels, which play a role in PMS symptoms. Case-control study, 2017 Do anxiety levels differ in soccer players with and without PMS? Yes. Players with PMS had significantly higher anxiety levels than those without (p = 0.002). A chemical called IL-10 may help protect against anxiety, but this protection didn't work the same way in players with PMS. Survey study, 2017 How many young women have premenstrual syndrome? The abstract is mostly in Polish and incomplete, so we cannot give a clear answer about prevalence from the available text. Survey study, 2016 Does eating fish help reduce PMS or PMDD symptoms in female athletes? Fish or dried fish consumption was associated with lower risk of poor athletic performance caused by PMS or PMDD in female athletes. The overall prevalence of PMS and PMDD was similar in athletes and nonathletes. Survey study, 2016 Does PMS increase the risk of stress fractures in teenage athletes? Among teenage athletes, 8.9% had moderate-to-severe PMS. Those with strong physical premenstrual symptoms had 1.66 times higher risk of stress fractures, suggesting PMS symptoms may increase injury risk. Cohort study, 2015 Does muscle strength change during the menstrual cycle in female athletes? Yes, in this very small study. Muscle strength declined during the premenstrual week in 10 young athletes, though mood didn't change. Survey study, 2015 Does regular running reduce PMS symptoms? Yes. Women who ran regularly 3 times a week for 20-45 minutes had much fewer PMS symptoms than women who didn't exercise, including less pain, fewer mood changes, and less bloating. Survey study, 2015 How common are PMS and PMDD in college athletes and do they affect athletic performance? About 8.6% of Japanese college athletes have moderate to severe PMS and 2.9% have PMDD. Nearly half of athletes (44.3%) said their athletic performance suffered during their cycle. Case-control study, 2014 Do women with PMDD have different brain activation during emotion processing? Women with PMDD showed lower activation in certain brain emotion-processing regions, especially those carrying a specific gene variant (Met-allele). This is suggestive evidence but based on a small study. Review, 2013 Does exercise help or hurt women's menstrual health? Moderate exercise improves menstrual regularity and reproductive health. But excessive exercise without enough nutrition can cause loss of periods, weak bones, and eating disorders. Survey study, 2013 Do female athletes have worse premenstrual symptoms during competition? Some do, and the type of sport matters. Individual athletes report more psychological stress during their menstrual period than team athletes do. Non-randomised trial, 2013 Does 8 weeks of aerobic exercise reduce PMS symptoms? Yes, 8 weeks of aerobic exercise three times weekly significantly reduced PMS symptoms and both physical and psychological symptoms compared to a control group (p≤0.001). Case-control study, 2011 Does personality affect whether athletes develop PMS? Possibly. Certain personality traits were associated with PMS in athletes, including strong drive for performance, low need for help, and introversion. Survey study, 2011 Does PMS affect how well female soccer players perform? Among 112 Brazilian indoor soccer players, 47.32% had PMS. Those with PMS reported their performance was affected, with depression, irritability, and difficulty concentrating being common symptoms linked to performance impact. Case-control study, 2010 Are personality traits different in women with PMDD? Yes. Women with PMDD showed higher levels of neuroticism-related traits including anxiety, stress susceptibility, embitterment, and mistrust than healthy women. These traits were stronger in women with more severe symptoms and linked to a genetic variation in the serotonin transporter gene. Survey study, 2008 Do genes related to mood and stress change during the menstrual cycle? One stress-related gene (FKBP5) showed lower activity in the follicular phase compared to other phases. Anxiety scores also changed during the cycle, but these two changes were not connected to each other. Non-randomised trial, 2004 Does serotonin activity change across the menstrual cycle? Yes. Serotonin transporter binding was highest in the late follicular phase (right before ovulation), while serotonin receptor binding was highest in the early follicular and early luteal phases. These changes correlated with estradiol and progesterone levels. Non-randomised trial, 2003 Do women with premenstrual dysphoria have different serotonin genes than others? Women with premenstrual dysphoria have fewer serotonin transporter proteins on their blood cells than controls, but genetic differences in the serotonin transporter gene do not explain this. Case-control study, 2003 Does PMS affect balance and body awareness during the menstrual cycle? Yes. Women with PMS had significantly worse balance and less ability to feel their knee joints moving compared to women without PMS. Case-control study, 2002 Do women with both seasonal affective disorder and PMDD share genetic risk factors? Yes. Women with both SAD and PMDD were significantly more likely to have a specific genetic variation and family history of mood disorders, suggesting they share genetic vulnerability to both conditions. Review, 1999 Does the birth control pill help female athletes manage PMS and other health issues? The birth control pill may help athletes control PMS symptoms and menstrual bleeding and may improve athletic performance. Effects on bone health and injury prevention are unclear, and individual responses vary. Survey study, 1998 Is knee ligament injury more likely at certain phases of the menstrual cycle? Yes. Female athletes were more likely to injure their knee ligament during the ovulatory phase and less likely during the follicular phase. Non-randomised trial, 1994 Is there a blood cell marker linked to PMS symptoms? Possibly, but we cannot be confident. A small pilot study found a link between a cell transport mechanism and premenstrual symptom severity in the week before the period, but the groups were too small to confirm this. Survey study, 1993 Does the menstrual cycle affect how well female athletes perform? Athletic performance may vary across the menstrual cycle, with better performance right after the period ends and worse performance during the premenstrual time and first few days of menstruation. However, research results have been inconsistent. Survey study, 1992 Does the menstrual cycle affect mood, especially in women who exercise hard? Women with regular periods showed marked negative mood changes before menstruation compared to mid-cycle. Heavy endurance running training worsened overall mood. Cohort study, 1989 Are soccer injuries more common at certain times of the menstrual cycle? Women soccer players had more traumatic injuries during the premenstrual and menstrual period compared to other times in their cycle, especially if they had symptoms like irritability, breast swelling, or abdominal swelling. Women using birth control pills had significantly fewer injuries. Cohort study, 1984 What affects menstrual patterns in teenage girls? Exercise and body fat did not affect menstrual regularity or pain. However, girls living at boarding school (away from home) were more likely to develop irregular cycles than girls living at home. Review, 1983 Does intense athletic training disrupt menstruation? Athletic training can disrupt periods, especially with significant weight loss and stress, though the causes are similar to non-athletes. This is a literature review, so certainty is limited. Survey study, 1964 How common are mood and physical changes around menstruation? Very common. One in nine women reported severe pain, irritability or headache, and one in four had moderate to severe premenstrual tension. Psychological symptoms were linked to personality traits related to anxiety. Show more studies Ask AI about this page Copy prompt ChatGPT ↗ Claude ↗ Perplexity ↗ Google AI Mode ↗ Grok ↗
