Methods: Two hundred eleven high school students resided in Taipei area were recruited in the study, including control group (C, n=40), who didn’t participate in any sport club, badminton group (B, n=48), track and field group (TF, n=40), taekwondo group (T, n=43) and swimming group (S, n=40). The multiple impendent analysis (physion XP) was selected to measure the body composition, included body mass index (BMI), the percentage of body fat (%BF), the percentage of body lean mass (%BLM), and the percentage of lean mass of limbs. The %LMLR means Left side and Right side’s Lean Mass percentage; also it means lean mass’s balance for left and right. The regular average of %LMLR is 95% to 105%. If the value of %LMLR lower than 95%, means the lean mass of right side is higher than left side. If the vslue of %LMLR is higher than 105%, means the lean mass of left side is higher than right side. The ratio of Lean Mass for Upper Limb and Lower Limb (%LMULLL) indicates the rate of lean mass of upper limb and lower limb. The items of skill-related physical fitness included agility, balance, coordination, power, reaction time and speed. Data were analyzed by descriptive statistics, one-way ANOVA. Results: In body composition, there was no significant difference in body weight and BMI among the five groups. But %BF in the B, TF, T, and S were significantly lower than C, while %BLM were significantly higher than C. In terms of %BLM in upper limb, S was significantly higher than B. In term of %BLM in lower limb, T was significantly higher than S. In terms of %LML in upper limb, the lean mass for the right side was higher than the left side in B (93.1%). In terms of %LML in thigh, the lean mass for the right side was higher than the left side in T (92.2%). In terms of %LML in lower leg, the lean mass for the left side was higher than the right side in T (106.8%). In terms of %LMULLL, C was significantly higher, and S was significantly lower. In terms of speed, agility, and power, B, TF, T, and S were significantly better than C. In terms of speed and reaction time, TF was better than B, T, and S. In the agility, B, TF, and T were better compared to S. Conclusions: The male students in senior high schools who participated in various sport clubs have significant better performance in body composition and skill-related physical fitness. The %BLM of right upper limb in B is higher than the left side. The %BLM of right thigh in T is higher than the left side, while the %BLM of left lower leg is higher than right side. The male students who participate in sport teams had significant better performance in speed, agility, and power. The students in TF present better performance in speed and reaction time when compared to the students in other teams. The students in S team performed significantly lower agility compared to the students in other teams. The findings of the research indicates that the male students in senior high school, who participate in sport teams, have significant better body compositiom and skill-related physical fitness.
