INTRODUCTION This research was aimed at finding how to overcome weakness and decline of growth caused by lack of exercise in adolescents by improving their daily life habits. In this experiment, the levels of stress hormones - ACTH, GH, Testosterone, Cortisol, Insulin- were observed by dividing students into two groups, a continuous circuit exercise(CE) group and a non-continuous circuit exercise(NCE) one apart from the regular physical education curriculum to verify the different effects between CE and NCE. METHOD This research was conducted by fourteen second grade students in G middle school in G City who were splitted into two groups of seven each, a CE group and a NCE one. Circuit training program was comprised of ten exercises involving five aerobic exercises and five resistance ones each ? the frequency of CE (three times a week, once a day, 30-minute workout) and that of NCE (three times a week, three times a day, 10-minute workout) SPSS ver. 18.0 program was used for two-way RM ANOVA to process the data and the result were statistically significant at level of p<.05. RESULT The CE group has brought meaningful changes of Testosterone(p<.01) and Insulin(p<.001) after of 12
weeks. Comparison of two groups showed that CE increased more Insulin(p<.01) than NCE one because of the interaction effect. CONCLUSION This study revealed that there’s no difference of the hormonal changes between CE and NCE group except Testosterone and Insulin. The results obtained in this study say exercising is more related to the total amount of time rather than the method of CE and NCE. Therefor later, Studies should be done considering sex, age, the number of examines and diverse research objects like athletes |
