| Abstract |
Obesity have increased in all age groups by the rapid economic growth and changes in sedentary life and dietary habits. In particular, the obesity is increasing rapidly in children. In addition, obesity causes attenuated lipid metabolism, and result in obesity related diseases. The purpose of this study was to investigate the effects of rope jumping and adlay intake on health related fitness, serum cholesterol and leptin concentration in children. 24 healthy and obese children were randomly assigned to rope jumping with adlay intake group(EXA, n=8), rope jumping group(EX, n=8) and control group(CON, n=8). Rope jumping intensity(40~70%HRR POLAR), the frequency(3 times per week, 40 minutes per exercise session) was performed for 12 weeks with adlay intake of 15g of adlay. The muscle mass(EXA: 7.9%, EX: 9.7%, p<0.05), muscular strength(EXA: 9.3%, EX: 5.7%, p<0.05), muscular endurance(EXA: 12.4%, EX: 18.4%, p<0.01), flexibility(EXA: 13.0%, EX: 5.5%, p<0.01), cardiorespiratory endurance(EXA: 12.6%, EX: 12.7%, p<0.05) in both group EXA and EX were significantly increased but Con group was significantly decreased in cardiorespiratory endurance(CON: -5.9%, p<0.05). Therefore, both group EXA and EX were improved in health related fitness than group CON. The HDL-C in group EXA(2.1%, p<0.001) and group EX(2.5%, p<0.01) were significantly increased and The LDL-C in both group EXA(-8.0%, p<0.01) and EX(-2.7%, p<0.01) were significantly decreased compared with the group CON. The Leptin in group EXA(-14.5%, p<0.01) and EX(-8.8%, p<0.01) were significantly decreased but group CON was significantly increased. The Leptin in group EXA and EX had significantly decreased compared with group CON. In conclusion, the results of this study showed that rope jumping with adlay intake has improved health related fitness, serum cholesterol and leptin concentration in obese children. Especially, the various studies on the rope jumping programs and adlay intake are needed to take a prevention against the obese youth. |
