Effects of Menstrual Cycle Phases on Selected Fitness Variable: In Case of Female Volleyball Players of Azazo Dimaza High School, Gondar City, Amhara Region, Ethiopia

An Analytical Approach

Abstract

The purpose of this study was to investigate the effects of menstrual cycle phases on strength and explosive power performance in female volleyball players at Azezo Dimaza secondary school. The study was used longitudinal research type and prospective design. According to the inclusion criteria 25 female volleyball players were selected from grade nine students purposively. The data was collected using three performance tests at different time point. These tests were pushes up, sit ups and standing long jump. Participants were exposed for three separate occasions during each menstrual cycle phases, consisting of two familiarization sessions and one actual test for each performance measurements. Then mean and standard deviation were computed and data were reported as mean ± SD. As well as, Repeated Measure ANOVA followed by a Bonferroni post hoc test at p < 0.05 were used. In the present study, the subject’s menstrual cycle was 28.32 ± 1.69 days, their average age, height, weight and BMI was 15.76 ± 1.25yrs, 1.64 ± .049 m, 47.72 ± 5.07kg and 17.73 ± 1.98 kg/m². The pushup test mean scores during the follicular phase, menstrual phase and luteal phase were statistically significantly different (F (1.063, 25.501) = 4.780, p < 0.05). Likewise, the sit up and standing long jump tests mean scores for during follicular phase, menstrual phase and luteal phase were statistically significantly different (F (1.433, 34.386) = 5.651, p < 0.05) and (F (1.991, 47.779) = 17.947, p = 0.00) in that order.
