Abstract:
The purpose of the present study was to determine the relationship among Leg Strength, Leg Length and Speed of Inter College Level Sprinters. For the purpose 20 male Inter College level Sprinters age ranged from 17-25 years of various participating colleges in the Dibrugarh University Inter College Athletic Meet 2014-15 were selected as the subjects. The required data were collected on the explosive strength, leg length and speed respectively by using Standing Broad Jump, measuring tap and 30 Yard Dash and score were recorded in centimeter and second respectively. For the statistical analysis the Pearsons’ Product Moment Co-relation statistical technique was employed. To find out the relationship among the selected three variables Partial and Multiple correlations technique was also employed. To test the significance in correlation between the variables the t test was used and the level of significance was observed at 0.05 level of confidence. On the basis of findings it was found that there was no significant but slight positive correlation between leg length and Explosive leg strength (r₁₂ = 0.072 < tabulated r value 0.433) and slight negative correlation between explosive leg strength and speed and leg length and speed (r₃₂ = -0.31 & r₁₃ = -0.0063 < tabulated r value 0.433 ). When significance was tested, no significant relationship between Leg length and Explosive leg strength, explosive leg Strength and Speed, Leg Length and Speed (r_{12 =} 0.30, r₁₃ = -0.026 and r₂₃ = - 1.46 < tabulated value 2.101). The positive partial co-relationship among the variables; in case of r_12.3 = 0.071 and negative in partial co relationship r _13.2 = - 0.029 and r _23.1 = - 0.32 was observed. It was also further conclude that there are slight positive correlation among explosive leg strength, leg length and speed was observed (R_1.23 = 0.070, R_2.13 = 0.32, R_3.12 = 0.002).
