Abstract

Excessive physical activity is one factor that can cause menstrual disorders. Disorders that can occur include the absence of menstruation (amenorrhea), bone thinning (osteoporosis), irregular menstruation or intermenstrual bleeding, abnormal growth of the uterine lining, and infertility (Asmarani, 2010).

Quasiexperimental design was employed and participants (N = 8) were purposively taken from the academy. Method of data analysis includes frequency, percentages, histogram, mean, standard deviation and Wilcoxon Signed Rank test. The result of this study shows athletes height (1.61± .027 meter), weight (51.88 ± 4.05Kg), BMI (19.88 ± 1.39), variation of menstruation period occurrence was between 5- 23 day, athletes show moderate premenstrual Syndrome symptom and the posttest ranks of PSM symptoms median score were significantly higher than PSM symptoms median score at Z = -2.714, p = 0.05. The finding of this study concludes that 12 weeks middle distance training increase the severity level of PSM symptom from pretest to posttest of experimental group. The study suggests that menstrual dysfunction due to high-intensity training recommended that menstrual function returned to normal by decreasing the training intensity or stopping the training for a while.
