Ten adolescent elite handball players playing in national club league (16.4 ± 0.69) and 10 adult handball players (23.55± 2.69) participated in this research. They performed triple shooting و assuming in a match situation and electrical activity of the Biceps brachii, Triceps brachii, pectorialis major muscles and three anterior, middle and posterior parts of deltoid was recorded using surface electromyography. Parameters related to the muscular activity pattern, including time, peak, action amplitude and contraction sequences were obtained. The results of t-student statistical test for two independent groups (p≤ 0.05) shown that there were no significant difference between time, peak and electrical activity amplitude variables between groups. It seems the factors such as experience in adolescent athletes, better utilization of muscle and being close to the end of puberty makes no difference between adolescents and adults.
