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). Wiarto (2013)explains that in sports discussed about
menstruation is an irregular menstrual cycle (oligomenorrhea or reduced menstrual
frequency) or menstruation stops beyond 90 days (amenorrhea or absence of menstrual
cycle).The purpose of this study was to assess the effect training on menstrual dysfunction of
Athlete Tirunesh Dibaba Athletics Training Centre Female Middle Distance Runner. 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.
