Abstract

Background and Objectives: Glenohumeral joint is mostly affected in overhead athletes mainly in fast bowlers. Insufficient force generation due to decrease in shoulder joint flexibility and improper positioning of scapula might affect the performance. So, the objective of the study was to compare the acute effect of ballistic and sleeper stretching techniques on scapular dyskinesis, shoulder flexibility and bowling speed.

Methodology: 30 subjects with scapular dyskinesis were selected and divided into two groups 15 in each group. Group A received ballistic stretching technique and Group B received Sleeper stretching technique in combination with static stretching for 1 week. SD, Bowling speed and shoulder flexibility were assessed by using KLSST, Bushnell velocity gun and Apley’s back scratch test respectively.

Results: Both Group A and Group B statistically significant change in means of scapular dyskinesis, Bowling speed and shoulder flexibility which means were analysed from pre- intervention to post-intervention within the groups with p<0.000.

Conclusion: The present study concludes that the ballistic stretching and sleeper stretching shown statistically significant effect on improvement of scapular dyskinesis, bowling speed and shoulder flexibility. The improvement obtained found no difference between both the stretching techniques on improvement of scapular dyskinesis, bowling speed and shoulder flexibility.
