Background and Purpose: The purpose of this study was contribute towards the discrimination of the effects of open kinetic and closed kinetic chain strengthening exercises. This study aims objectively to evaluate the benefits of these training modalities and elucidate their effects. Subjects and Methods: The participants were school basketball players with the average age of 16 years, divided into two groups randomly to open kinetic and closed kinetic chain strengthening exercises. Exercises were designed differently for each group and evaluated using vertical jump performance and standing long jump. Results: The results shows that closed kinetic chain exercise training were more effective than open kinetic chain exercise training in improving the jumping performance for the basketball players. The values of these subjects for closed kinetic chain exercises 3.46+0.956 and 3.66+1.19 when compare to 1.46+0.80 and 2.13+0.88 for open kinetic chain exercises in vertical jump and standing long jump performance respectively measured in meters. Conclusion: Closed kinetic chain exercises are more effective in training the individuals who require jumping as a part of their sports activity and more useful in vertical jumping training which is important for the basketball players.
