A study to evaluate the acute effect of various stretching in warm-up routines on vertical jump performance in amateur basketball players

Background and Purpose: A recent study reported promising clinical results using dynamic stretching and ballistic stretching as a warm-up exercise in improving vertical jump performance for basketball players. Objectives: This study aims to determine the acute effect of dynamic and Ballistic stretching in a warm up routines on vertical jump height in amateur basketball players. Methodology: In This experimental study sixty subjects of amateur basketball players with a mean age of 22.46+1.21, were randomised to Dynamic stretching, Ballistic stretching and control group randomly. Each subject were pretested for vertical jump on one day and for 7days each subject received 10 min jog warm-up and Dynamic and Ballistic stretching groups received Stretches addressed the major muscle groups of the lower body (Gluteal, Hamstrings, quadriceps, adductors, hip flexors, gastrocnemius and soleus) stretches performed in both the legs for Fifteen repetitions per leg for three sets followed by post test for vertical jump everyday for a week. Results: The results analyzed using ANOVA showed that there was significant variations p<0.05 in the mean improvement of all the groups considered thus accepting the experimental hypothesis stating that there is significant difference with stretching protocols in improving the vertical jump performance of Amateur Basket ball players. Mean improvement values of the amateur basket ball players belonging to group Dynamic stretching, Ballistic stretching and control group (1.42, 0.97, and 0.25) shows Group-A players trained with Dynamic stretching had a significant improvement with their vertical jump performance when compared to the group trained with Ballistic stretching and the control group. Conclusion: This study shows acute effect of both Dynamic stretching and Ballistic stretching have got beneficial effect in improving the Vertical jump performance of amateur Basketball players. But acute effect of Dynamic stretch has superior hand in improving the Vertical jump performance of amateur Basketball players.
