ABSTRACT |
Ann, E.S., Lee, J.Y., Park, S.H., Han, T.K., Kang, H.S. Correlations of blood leptin and obesity indices and cardiorespiratory fitness according to 12-week aerobic exercise in premenopausal women. Exercise Science, 15(3), 251-258, 2006. The purpose of the study was to investigate effect of obesity indices and cardiorespiratory fitness on decrease of blood leptin concentration by analysing correlations of blood leptin concentration, obesity indices, and cardiorespiratory fitness according to 12-week aerobic exercise. A total of 46 apparently healthy premenopausal mid-life women were recruited via fly and local advertise- ment. 12-week aerobic exercise was executed dance exercise to 50-70% of VO2max, 60min/day, and 3 times/week. Paired t-test of variance showed that obesity indices, blood leptin concentration, cardiorespiratory fitness had significant difference according to 12-week aerobic exercise. Also, pearson's correlation of all variance had significant correlations. Especially, decrease of blood leptin concentration had greatest negative correlation with improvement of cardiorespiratory fitness. And a stepwise regression analysis showed that improvement of cardiorespi- ratory fitness independently explained individual variation in decrease of blood leptin concentration. The current findings of the study suggest that improvement of cardiorespiratory fitness have strong relation with decrease of blood leptin concentration, and it may be metabolic process on obesity therapy by improvement of cardiorespiratory fitness. |
