Researchers are investigating how resistance training programs tailored to the menstrual cycle affect neuromuscular function in female athletes. This study compares training protocols that vary intensity based on menstrual phases with a control group of athletes using oral contraceptives. The trial aims to determine if aligning training intensity with hormonal changes during the menstrual cycle can improve muscle strength and related neuromuscular measures over 13 weeks. Participants are assigned to one of four groups: natural menstrual cycle with intensified training during the follicular phase, natural cycle with intensified training during the luteal phase, natural cycle with continuous training intensity, or oral contraceptive users with continuous training. Each group completes a 13-week resistance training program with two 90-minute sessions weekly. Training intensity is adjusted according to menstrual phases for the natural cycle groups, while contraceptive users maintain a consistent training load. Throughout the study, participants undergo neuromuscular assessments before and after the intervention in three menstrual phases: early follicular, late follicular, and mid-luteal. Measures include maximal knee extensor strength, voluntary muscle activation, rate of force development, muscle stiffness, and vertical jump height. Blood samples are collected for hormone level verification. The study monitors these outcomes to evaluate how menstrual phase-based training influences neuromuscular performance in female athletes.
