What Does the Research of Upper Extremity Plyometrics of Shoulder Performance and Rehabilitation Really Tell Us
Davies, GJ: Armstrong Atlantic State University , Savannah , GA. , USA .

 Educational Presentation:

Purpose: The purpose of this presentation is to present an overview of the research evidence regarding the applications of plyometric training of the shoulder complex.

Description:  A critical review of the literature of upper extremity plyometrics and the effects on shoulder performance and rehabilitation will be described.

Summary of Use: 1) DO NOT use shoulder complex single arm plyos on untrained subjects, 2) It takes more than 4 weeks of plyometric training to demonstrate a response in trained subjects, 3) Increases PROM-ER in trained subjects, 4) If concerned about anterior instability; DO NOT use single arm plyometrics in the 90/90 position, 5) Increases faster power of shoulder IR (>180 °/sec) in trained subjects [specificity], 6) Improves functional throwing performance in trained subjects, 7) Use in terminal phases of rehabilitation, 8) Retro-plyos can be used for increasing power in the elbow extensors, 9) Retro-plyos does not increase power in the GH-ER, 10) There needs to be specificity type of testing of similar muscle groups and similar movement patterns of training to provide a training response, 11) There is not a physiological overflow to other testing patterns of isolated joint testing, 12) There is not a physiological overflow to other testing patterns of functional total body testing, and, 13) When training 2-arms in a chest pass “technique”, a higher volume of work is necessary to create a training response.

Importance: Since many of the ASSET shoulder protocols include plyometrics in the terminal phases of rehabilitation, it behooves the clinician to be aware of the research evidence and the appropriate applications of the research in designing plyometric training programs for performance enhancement or for their patients.
