The purpose of this study was to investigate the effects of 16 weeks of spinning and bicycling exercises on body composition, physical fitness and blood variables in female adolescents. Subjects participated in this study were 24 female middle school students (12 spinning cycles, 12 general bicycles) attending to Seoul Yeoksam middle school. Each group was trained for 16 weeks, 3 times a week, and 1 hr per day after school. Body composition, physical fitness (1,200 running, sit-ups, back strength, sit and reach, side-steps) and blood variables (low-density lipoprotein cholesterol, glucose, reactive oxygen species, and malondialdehyde) were examined before and after 16 weeks of training. As the results, body weight did not show any significant difference; however, body mass index, and % body fat were significantly difference in spinning group. The enhancement in physical fitness factors were recognized in both groups, which was greater in spinning group in sit-ups, back strength, and side steps. Blood parameters were significantly difference between groups, but between group and time interactions were significantly difference in glucose and reactive oxygen species. In conclusion, this study suggests that 16 weeks of bicycle exercises were positive changes in body composition, physical fitness and blood constituents, indicating that spinning cycle is more beneficial as compared to ordinary bicycle.

This study aimed to provide fundamental data of core balance training (CBT) on Cobb angle and isokinetic torque and balance in unilateral exercised athletes. Forty-eight subjects were divided by control group (CON; n= 16), non-CBT exercised group in unilateral handed athletes (NEG, n= 16), and CBT exercised group in unilateral handed athletes (EG, n= 16), respectively. Although the group by time interaction in the Cobb angle and in the isokinetic torque were not significantly changed in the EG, the balance of the EG showed significantly improved. As conclusions, these results informed that the 16-week CBT would provide a positive effect on the balance except for the Cobb angle and the isokinetic torque.
