Brief Summary:
In shoulder rehabilitation the inclusion of kinetic chain exercises is advocated in order to provide the necessary energy transfer to produce optimal force with minimal energy consumption Closed kinetic chain CKC exercises are defined as exercises in which the distal segment is stabilized by encountering significant resistance while the proximal segment moves In contrast open kinetic chain OKC exercises allow the distal segment to move freely without any resistance Recently the importance of closed kinetic chain CKC exercises has increased in enhancing shoulder joint neuromuscular control by improving dynamic shoulder stability and joint position sense
The most current shoulder rehabilitation protocols include exercises for restoration of scapular muscle imbalancesThere exist studies investigating the levels of scapular muscle activation during CKC exercises Researchers have shown that most CKC exercises especially push-ups and plank variations with the shoulder in the 90 position generally provide high SA activity and an optimal UTSA ratioIn the literature there is limited information on how the level of shoulder elevation affects scapular muscle activity and ratio during closed kinetic chain exercises in the prone position To effectively prescribe CKC exercises commonly used in rehabilitation and athletic programs a clear understanding of shoulder elevation changes muscle activity during these exercises is required
Our hypothesis is that glenohumeral joint elevation status will alter scapular muscle activation and activation rates

Detailed Description:
Twenty-two healthy male individuals to recruited in the study Conducting a power analysis through GPower considering a moderate effect size f 025 an alpha level of 005 and a power of 08 The outcome of this analysis indicated a required minimum sample size of 21 individuals This study was used a randomized repeated measures cross-over design Muscle activation levels during maximum voluntary isometric contraction MVIC of each muscle Upper trapezius Middle trapezius Lower trapezius Serratus anterior will be recorded to normalize muscle activation levels during closed kinetic chain exercises Muscle activation levels will be evaluated with a surface electromyography device Noraxon Myomotion USA
