Introduction: Female exhibit changes during menstrual cycle that may affect different sport performance variables. The decrease in performance of counter movement jump (CMJ) has been related with muscle damage and loss of muscle function after strength training. Few studies have investigated these effects after an intense strength training in women1. Therefore, the purpose of this study was to evaluate the influence of hormonal fluctuation along the menstrual cycle in lower-limb muscle function and damage in female athletes Methods: Five eumenorrheic women (age 30±4 years, height 164±5.2 cm, body mass 60±6.3 kg) experienced in resistance training, performed a 1RM test to determine their maximal back squat load. After load estimation, they completed an eccentric-based resistance protocol consisting of 10 sets x 10 reps of back squat 2 in order to promote muscle damage. Both exercises were carry out in three different and randomized occasions: early follicular phase (EFP), late follicular phase (LFP) and luteal phase (LP) of menstrual cycle. Participants also performed CMJ before (pre-trial), and 0h, 24h and 48h after eccentric exercise (post-trial). Jump height was measured by using MyJump App 3. Mixed linear model was conducted to analyze repeated measures. Results: Mean jump height was 27.9±5.6 cm, 28.5±2.6 cm, and 29.2±7 cm for the previously mentioned phases. Mixed linear model showed no significant effect of phase in CMJ performance (F2,8.007=2.047; p=0.191). Jump values were significantly affected by moment being post-trial ones significantly different from pre-trial measures (F3,16.048= 4.21; p<0.05). Mean height values for pre-trial and 0h, 24h and 48h post-trial measures were 30.1±6 cm, 25.7±3.8 cm, 29.6±5.7 and 28.8±5.1 cm, respectively. No significant effect of interaction between phase and moment was observed (F6,15.832=0.319; p=0.971). Conclusion: An eccentric-based resistance exercise affects muscle function or damage in women as CMJ performance was significantly lower 0h post-trial than pre-trial. Nevertheless, muscle function may not be influenced by hormonal fluctuation as no differences among phases were observed. This finding could be due to sample size as our results are preliminary. Further studies are needed to evaluate sex hormone effects in women performance. Contact: n.romero@upm.es References: 1. Jakeman JR, Byrne C, Eston RG. Eur J Appl Physiol. 2010;109(6):1137-1144. 2.
