중년여성 마라톤과 에어로빅댄스 동호인의 운동참여에 따른심폐기능 및 혈액성분 비교 연구

초록

The purpose of this study is to prove an effect of the exercise by observing differences among cardiorespiratory function and blood components of middle aged female members of marathon club and the aerobic dance club who participate in the life-time sports. The subject of study is women of marathon club(n＝7) and aerobic dance club(n＝7) in 40s. Intensity of exercise is 60～85% and 85～100% of HRmax. It is as follows：BMI and %fat of the marathon group appear obviously lower difference than those of aerobic dance group in physical construction.(p<.05). HRrest of the marathon group is much lower than that of aerobic dance group in cardiorespiratory function(p<.05). All O2max, VEmax and Exhau stion-time of marathon group are higher than those of aerobic dance group, and there is a statistical difference(p<.05). Blood lactate concentration of marathon group appears to be higher than that of aerobic dance group in 5minutes and 30minutes of recovery except at rest. As the peak of both groups appears in 5minutes, it shows a statistically obvious difference(p<.05). However, recovery rate of blood lactate concentration of marathon group reduced up to 60% is superior to that of aerobic dance group reduced up to 68.5% in fatigue relieving capacity(p<.05). Blood components of marathon group is higher than that of aerobic group at rest, in 3min and 30minutes of recovery in RBC, Hct and Hb. There are statistical differences depending on the measuring time(p<.05), while there is the only difference in RBC of the comparison of two groups(p<.05). As a consequence of the facts above, exercise using the whole body, which is a form of running, is determined to be more suitable for reduction of weight, cardiorespiratory function, and improvement of tolerance ability to get rid of fatigue.
