THE CORRELATION BETWEEN HIGH FREQUENCY PHYSICAL ACTIVITY TOWARD HEMOGLOBIN LEVEL DECREASE AND THE OCCURANCE OF DYSMENORRHEA IN WOMAN AEROBIC INSTRUCTOR.

Abstract

People awareness to live a healthy lifestyle is getting higher. Doing exercise considered as a trend in our society. Our Society has recognized the positive effect from doing regular exercise. Exercise for health needs a right measurement because not every exercise will give positive effect to our body. Aerobic gymnastic is one kind of recreation sport, not competition sport or achievement, so the best frequency is 5 times but less then 7 times a week. Our body needs to recover after doing exercise, so that by doing exercise one and in another day, it will give our body a chance to recover itself. High intensity exercise is suspected to influence the menstrual cycle and reproductive health. The aim of this research are to find out the differences of haemoglobin level decreasing during the menstruation, dysmenorrhea incidence, and menstrual cycle regularity on high as well as low intensity instructor.

Subjects of this research are forty aerobic instructor women who fulfil the subject criterion. The subjects are divided into two groups based on the frequency of their training activity per week namely low intensity for those who train less than or equal to seven times per week and high intensity for those who train more than seven times per week. The research employs tools in a form of questionnaire and Sahli haemoglobin measurement. After collecting the data of each variable, it continues with statistic test using T-test and Chi Square.

The percentage of the regular menstruation cycle in a low intensity instructor is 85% and in high intensity instructor is 70%. Percentage of the dysmenorhea case in low intensity instructor is 35% and in high intensity instructor is 45%. Percentage on the decreasing of haemoglobin in low intensity instructor is 0,71 ± 0,51 gram/dl and in high intensity instructor is 0,79 ± 0,47 gram/dl.

In conclusion, this research doesn’t find any significant differences related to the menstrual cycle regularity, frequency of dysmenorrhea incident and the decreasing of haemoglobin level during the menstruation period between the high intensity instructor and low intensity instructor.
