Objective: To find out effect of nine months Soy supplement on strength variables, hand grip strength and back strength in female players of tribal area.

Materials and Method: Ninety-six female players from tribal sports campus of (average age = 14.44. height= 150cm, weight = 40.49kg) were selected for the present study. Subjects were randomly divided into experimental group (N = 49) and control group (N = 47). The subjects of experimental group consumed soy ladooof 50gm/day (10.3gm protein) for nine months. Hand grip strength and back strength of all the subjects were measured before the experiment and at every three months of supplementation of soy ladoos. Data was analyzed by SPSS package version.

Results: Significant effect of soy ladoo supplementation was observed (p<0.00) between pre, mid, pre-post and post measures of Hand grip strength and back strength in experimental group. Soy ladoo supplementation significantly improved performance in hand grip strength and back strength of experimental group (respectively P<0.00; F= 44.00; ES = .321, P<0.000; F=23.59, ES = .202}

Conclusion: Consumption of soy ladoo of 50 gm/day (10.3 gm protein) improved hand grip strength and back strength in tribal players.
