subject: Effects of a Shoulder Injury Prevention Strength Training Program [print this page] Effects of a Shoulder Injury Prevention Strength Training Program
This is a literature review study that is going to review the topic, effects of a shoulder injury prevention strength training program, on eccentric external rotator muscle strength and glenohumeral joint imbalance in female overhead activity athletes. Under this study, reasons why the study was done, how it was done, and the results and conclusions that were drawn will be reviewed. The disparity of the eccentrically-activated exterior rotator cuff muscles against the concentrically-activated internal rotator cuff muscles is the most important risk factor for glenohumeral joint injuries in overhead goings-on athletes
Purpose of the study
The purpose of this study is to evaluate the effects of a shoulder injury
Prevention strength training program on eccentric external rotator muscle strength and
Glenohumeral joint imbalance, in female overhead activity athletes.
Methods and scope of study
12 participants took part in this study all through the preseason training.(n=6) was the first team participating in a 4 times a week in a span of 5 weeks ,external shoulder rotator muscles strength training program which was next to their preseason tennis training. The second team (n=6) took part in a comparable preseason tennis training program, although they did not conduct any upper body strength training.
Subjects
In this study the subjects were two collegiate women tennis teams made up of 12 women.
Protocol and procedures
Pre-and post training data of 5 maximal eccentric external, immediately followed concentric internal contractions on a kin-com isokinetic dynamometer, were compared.
Instrumentation
Kin-com isokinetic dynamometer
This is a quantitative type of variable as the measurements are continuous.
Findings
The shoulder strength teaching program significantly enlarged eccentric external total work without momentous effects on concentric interior total work, concentric internal mean peak force, or eccentric outer mean peak force.
Conclusion and recommendation
Through increase of the eccentric outer sum exercise, capacity in the absence of a subsequent increase in the concentric inner total exercise capability, this strength teaching program potentially reduces shoulder rotator muscle imbalances and the risk for shoulder injuries to overhead activity athletes.
Nonisokinetic dynamometer based force training studies ought to focus on resulting concentric and also applicable eccentric strength gains of the exterior rotator cuff muscles. This will help in the reduction in glenoumeral joint muscle imbalance, to do away with the earlier notion that presently used shoulder strength training programs do not successfully reduce the peril of shoulder damage to the overhead activity athlete.
