The musculoskeletal causes the loss of beauty and decrease the mechanical performance of individuals the functions of the steps of the foot of the floor are the attraction and distribution of forces and the provision of the stability of the body. The purpose of this study is comparison of arch index, weight distribution, balance and selected musculoskeletal disorders in active and non-active adolescences. The sample consisted 50 teenagers (28 active and 22 no actives) who were randomly targeted. Subject Demographic include Age of non-active adolescence (12/46± 1/10), Height (157/69 ± 8/48 cm) and Weight ( 46/65 ± 8/45 ), Age of Active grope ( 12/26± 1/13 ) , Height ( 153/91± 10/09) and Weight ( 44/52 ± 7/76 ).For statistical analysis of data K-S test for normal distribution of data and, used T- test in order to compare the two groups of active and non-active and Umanvitni the level of 0.05. The descriptive findings indicate that the mean of musculoskeletal system in adolescent adolescences is more active than active. the results of the independent t test for comparing the balance performance among the two active and passive groups showed significant correlation (sing=0/04), but there was no significant difference in the foot index parameters and weight distribution. The musculoskeletal diseases play a critical role in the mechanical function of individuals. The posture and balance performance in active is better than non-active adolescences , but no difference was observed between the foot index and weight distribution in active and inactive juveniles. The more complex research is need to test this hypothesis.
