TAKE‐OFF CHARACTERISTICS OF LONG JUMP:A KINEMATIC ANALYSIS IN FEMALE ATHLETES (original) (raw)

The present study intended to find out the relationship among the kinematic variables of Take‐off Characteristics in long jump and also find out which kinematic variable was most contributing factor in the enhancement of the long jump performance. The sample consisted of 5 female long jumpers in the age group of 17-24 years'with mean21.47,the test item (parameters) selected for examined Linear kinematic is Center of Gravity and angular kinematic namely (angle at ankle joint (right, left), angle at knee joint (right, left), angle at hip joint (right, left), angle at shoulder joint (right, left), angle at elbow joint (right, left)). The statistical TechniqueRegression analysis wasused for the present study. The present finding towards, kinematic parameters are quite thought provoking and noteworthy. Linear kinematic (center of gravity) not showed a statistically significant difference and the angular kinematic variables revealed that significant Difference of Right knee angle with the performance in long jump.The regression analysis was reliable as the value of R 2 was 0.868. the one variable(right knee angle) selected in that regression equation explain 86.8% of total variability explain by the model since f value for the regression was also highly significant, the model was reliable also provides further insight into long jump, although not all variables associated with real jumping performance. They found that jump performance was enhanced by a high approach speed, a high knee angle at touchdown and high (concentric and eccentric) muscle strength. Factors which did not have a great influence on jump distance were tendon compliance, muscle fibre contraction speed and some aspects of muscle architecture.
