Abstract
The purpose of this study was to study the effects of backward walking exercise on body composition and maximal oxygen uptake in overweight adolescents. Samples were 20 male students who enrolled course of Exercise Science for Health, aged 18-22 years, with body mass index (BMI) 23.00-27.40 kg/m2. They were equally divided into 2 groups by simple random sampling, the control (CON) group (did regular daily life) and the backward (BW) group. Subjects in the BW group walked backward at selected speed, 4.3, 5.0, and 5.8 km/hr at 1st, 2nd, and 3rd - 4th week, respectively. They underwent exercise program 5 times a week for 4 weeks. The variables were collected before and after training. The outcomes were analyzed using t-test at statistically significant differences at .05 level. The results showed that after 4 week of training, body composition and maximal oxygen uptake in BW group were significantly improve at .05 level. Furthermore, flexibility, leg muscular endurance and strength of the BW group were greater than the CON group at .05 level. In conclusion, backward walking exercise can improve body composition and maximal oxygen uptake including flexibility, leg muscular endurance and strength in overweight adolescents. This improvement may be related to backward locomotion which elicit a given energy expenditures and need more motor unit recruitment of leg muscle. The physiological variables were then response and improve on body composition and maximal oxygen uptake.
