What this Trial Is About

Researchers are studying the effects of training load and menstrual cycle phases on performance, health, and biological markers in elite and non-elite female athletes. This observational study aims to understand how hormone changes during the menstrual cycle influence physiological parameters, injury rates, and sport emotions. The goal is to identify periods of high training load and prevent over-training by tracking various health and performance indicators over one year. The study involves 200 premenopausal female athletes who will be followed for 12 months. Participants will be tested at three time points reflecting different training load phases: low, moderate, and high. Tests include blood sampling during menstrual cycle phases, stool sample collection for microbiome analysis, performance tests like VO2max and strength measurements, and questionnaires about health, nutrition, and psychological state. Both elite and non-elite athletes will be included, with schedules adjusted to their training plans and menstrual status. Participants will attend sessions to complete physical tests, provide biological samples, and fill out questionnaires multiple times during the study year. Blood tests will be drawn fasting and in the morning, timed with menstrual cycle phases when possible. Training load will be monitored using diaries, devices like Garmin watches, and subjective ratings. Injury data will be recorded by medical professionals. Researchers will analyze stool microbiome, serum metabolites, physical performance, body composition, and psychological measures. This comprehensive monitoring aims to clarify how menstrual cycle phases and training load affect female athletes over time.

Your Study Journey

Screening

Duration - 2 to 4 weeks

Participants are screened for eligibility to participate in the trial.

1 visit (in-person) for informed consent and eligibility assessment at the Wingate institute

Monitoring

Duration - 12 months

Participants track menstrual cycles using a smartphone app and record daily wellness status, training load, and food intake diaries throughout the 12-month study period.

Daily tracking with smartphone apps and diaries; no in-person visits for this stage

Assessment Periods

Duration - 3 assessment periods over 12 months

Participants undergo testing at three distinct time points reflecting different training loads (low, moderate, high) over the year, including questionnaires, blood tests, stool sample collection, and performance tests.

3 visits (in-person) for testing aligned with training phases; blood tests scheduled during specific menstrual phases for those with regular cycles
