An Investigation And Analysis Of Chinese Excellent Women’s Menstrual State

Objective:The research studies menstrual status of 85 Chinese elite women basketball players during their 2014 summer training-Based on the survey results,we divide these players into two groups.Then futher analysis the difference between the two groups,such as physical condition,comprehensive physical quality,aimed at making scientific advice for training,monitoring and players’ health.Methods:. We select 85 athelets of Chinese elite players,21.9±3.6 years old,and 8.3±1.36 years training.(1)Through questionnaires,we try to find out their menstrual cycle,and basing on the menstrual disorders, we divided them into two groups;(2)Testing the difference about specific speed,speed endurance and upper/lower-extrmity strength between the two groups;(3) Testing the difference about body morphology between the two groups;(4) Testing the difference about blood biochemical index between the two groups.Results:1) The number of menstrual disorders has negative correlation with strength shooting incidenceand bench press. score(P<0.05),but has no significant correlation with shuttle run,squat and physical fitness test score;2)There was no significant differences in body fat between the two groups,the bone mineral density of abnormal groupwas significantly lower than that of normal menstruation group.Bone mineral density was negatively correlated with the number of menstrual disorders(P< 0.05);3)The red blood cell and hemoglobin between the two groups were significantly different(P<0.01),and the menstral disorder occurred rate was significantly negative related with testosterone(P<0.01).Conclusions:(1) The results of menstrual survey were not good and there was 40% players has menstrual disorders.We recommends each team should make appropriate training plan according to players’physiological features.(2) The bone mineral desity sitiation was declined so that we mustn’t ignore.Women basketball players’menstrual disorder led to bone volume lost.The level of hormone had close relationship with bone mineral density,so coaches should make special attentionon nutrition about atheles.(3)It is so important for players that the level of hemoglobin,red blood cell and testosterone.We should continue to guide nutrition concepts and improve nutrition knowledge.
