摘要：Strength training can improve neuromuscular function in athletes. Most of previous researches have shown that heavy resistance training (55 – 80% of 1RM) influence morphological characteristics of adolescents. The goal of this study was to examine if 12 weeks of heavy resistance training (80 – 95% of 1RM) affects morphological characteristics of adolescents, in particular, voluminosity, body mass and subcutaneous fat tissue. Fifteen males participated in this study. Anthropometrics (body height, body weight, chest circumference, abdominal circumference, relaxed upper arm circumference, flexed upper arm circumference, upper leg circumference, abdominal skin fold thickness, m.tricepsbrachii skin fold thickness) and body composition(fat mass, fat free mass, muscle mass, intracellular and extracellular water) were measured before and after training program. Results has shown that there was significant differences (p<0.05) in variables: body weight, 4 circumferences, m. triceps brachii skin fold thickness and extra cellular water. From this study, it can be concluded that submaximal resistance training affects some morphological characteristics on anthropometrical level: voluminosity and skin fold, but have no effect on cellular level, except on extracellular water.
