Female participation in elite sport is rising, the most recent Olympic games, Tokyo 2020, was the most gender-balanced games in history but research within female athletes is lacking. This study investigated if different phases of the menstrual cycle (MC) influenced training schedules, sleep quality, arousal, and alertness in elite female mountain bike, road and cyclocross athletes. Methodological approach was coherent with Edinburgh Napier University’s ethics committee. Fifteen athletes (age: 29 ± 7.4 years, height: 1.7 ± 0.1m, body mass: 61.9 ± 7.7kg) from 9 countries, were part of the three-month study. The MC was split into two phases; follicular (FP) and luteal (LP), and participants were provided ovulation kits to identify the phases. As well as uploading training data over the three months, athletes tracked their MC symptoms, basal body temperature (BBT), body mass, perceived sleep, and psychological measures daily. BBT was significantly higher (p0.05). Further, no differences (p>0.05) between phases for the training variables such as average heart rate (FP; 126 ± 36, LP; 126 ± 38 bpm, p=0.85, d=3.82), training load (bTRIMP) (FP; 160 ± 155, LP; 170 ± 168 A.U, p=0.71, d=1.45), average speed (FP; 160 ± 155, LP; 170 ± 168, p=0.75, d=1.52) and rating of perceived exertion (RPE) (FP; 14 ± 3, LP; 14 ± 3, p=0.87, d=5.87) were observed. The MC phases did not appear to influence training schedules, sleep, or psychological changes. However, due to the online nature of the research, future studies are required for more controlled, lab-based research to determine the effects of MC in elite female athletes.
