The effects of 8 weeks of general physical education course (1) during morning and evening times on body composition, aerobic capacity and lipid profile among non-athlete students

Decreasing in physical activity, overweight and obesity are the main causes of increasing serum lipid profile. The interaction of these factors with each other and in response to exercise could be correlated with physiologic circadian functions. The aim of present study was to compare the effects of 8-weeks of general physical education course (1) at the morning and evening on aerobic capacity, body composition, blood lipids and lipoproteins among non-athlete students in Shahid Bahonar University of Kerman. 15 (evening group), 14 (morning group) and 15 (control group) subjects among non-athlete general physical education course (1) students were selected as volunteer sample. Fasting blood samples (12 to14 hours) were taken two times before and also after 8 weeks of intervention. The changes in serum lipids profile (TC, TG, lipoprotein HDL and LDL) were determined by enzymatic methods. The aerobic power and percent body fat were measured by Cooper test and skinfold technique respectively. The data was analyzed by a mixed two-way Split Plot ANOVA test (SPANOVA) and the significant level set as p≤0.05. The results indicated that 8 weeks of general physical education course (1) (one session in every week) had no significant effect on blood factors (TC, TG, HDL and LDL) and percent body fat (p>0.05). But, aerobic power of students regardless of time during the morning and evening were significantly increased (p<0.01). One session of general physical education course (1) would not be enough to improve student’s health, moreover there is no difference affect of performing these courses during the morning and the evening time.
