Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Objectives: To examine the sport-specific adaptations and investigate the effect of swimming stroke specialization in shoulder complex among adolescent competitive swimmers.

Design: Observational study.

Setting: Athletic facilities.

Participants: A total of 76 adolescents participated including n = 28 non-swimmers as Control Group (CG) and n = 48 competitive swimmers as Swimmers Group (SWG).

Main Outcome Measures: Strength of glenohumeral (GH) and scapular muscles (SM), mobility of GH (GH ROMs) joint, proprioception, pectoralis minor length (PML), posterior shoulder tightness (PST) were evaluated for all participants. Kerlan Jobe Orthopaedic Score (KJOC) was sed to evaluate for SWG. The tested shoulder physical performance parameters were compared between the groups.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Swimming Group (SWG)

The asymptomatic swimmers with no history of major upper limb injury or surgery and no injury history of upper limb in last 6 months, having experience in at least 5 years competitive swimming, actively participating in competitive swimming at least 1 year, competing at least in national level and having swimming stroke specialization in competitive swimming were included

No interventions assigned to this group

Control Group (CG)

The non-athlete peers with no competed in overhead sports like swimming, basketball, volleyball, tennis, baseball as professional or recreational, no history of major upper limb injury or surgery and no injury history in last 6 months participated in this study.

No interventions assigned to this group
