Abstract

The purpose
of this study was to compare body composition, anaerobic capacity, and hematologic parameters after intermittent complex training in high school soccer players. The subjects were 15 high school soccer players (age, 15.60±0.82 years; height, 171.93±5.65 cm; body weight, 61.32±7.43 kg). Clinical variables included body composition, anaerobic capacity, and hematologic parameters. Data were analyzed to compare between trials by paired sample t-test. As a result, there were significant differences in body weight (p<0.05) and muscle mass (p<0.05) of body composition after 4 weeks. There were significant differences in shuttle run (p<0.001) and heart rate in rest (p<0.05) of aerobic performance after 4 weeks. There were significant differences in lactate dehydrogenase (p<0.001), creatine kinase (p<0.001), all out lactic acid (p<0.01), and red blood cell (p<0.001) of hematologic parameters after 4 weeks. In summary, intermittent complex training for 4 weeks showed strong influences on body composition and hematologic parameters variables in high school soccer players.
