Does a land‐based compensatory strength‐training programme influences the rotator cuff balance of young competitive swimmers?

Abstract

During the repeated execution of the swimming strokes, the shoulder adductor and internal rotator muscles have a tendency to become proportionally stronger when compared to their antagonist group. This can lead to muscle imbalances. The aim of this study was to examine the effects of a compensatory training programme on the strength and balance of shoulder rotator muscles in young swimmers. A randomized controlled trial design was used. Forty male swimmers took part in the study and were randomly divided into two groups: an experimental group (n = 20) and a training group (n = 20). A control group (n = 16) of young sedentary male students was also evaluated. The experimental group subjects participated in a 16-week shoulder-strength programme with Thera-Band® elastic bands; the training group was restricted to aquatic training. Peak torque of shoulder internal rotator and external rotator (ER) was measured at baseline and after 16 weeks. Concentric action at 1.04 rad s(-1) (3 reps) and 3.14 rad s(-1) (20 reps) was measured using an isokinetic dynamometer. The strength-training programme led to an improvement of the ER strength and shoulder rotator balance in the experimental group (data from both shoulders at 1.04 rad s(-1)). Moreover, concentric action at 3.14 rad s(-1) presented significant differences only for the dominant shoulder. Findings suggest that the prescribed shoulder-strengthening exercises could be a useful training option for young competitive swimmers. They can produce an increase in absolute strength values and greater muscle balance in shoulder rotators.

Modelling the relationship between biomechanics and performance of young sprinting swimmers

“…technique) and hence performance. Such programmes aim not only to help one to excel but also prevent injuries (Batalha, Marmeleira, Garrido, & Silva, 2015); which is a concern that several S&C coaches have regarding the high rate of shoulder injuries in swimmers at such young age (Batalha, Raimundo et al, 2015).…”

Medical Care for Swimmers

“…Fatigue may lead to a short-term decrease in acromiohumeral distance [ 52 ]. As a result, a dryland program focusing on the shoulder external rotators and the scapular stabilizers would be of benefit and should be recommended as routine prophylactic measures [ 53 ]. Strengthening the internal rotators should be de-emphasized.…”

A systematic review on dry-land strength and conditioning training on swimming performance

“…Coaches have prescribed S&C training programs for decades to enhance swimming performance and/or prevent injuries [19][20][21][22]. Despite being a common practice, some coaches assume that S&C training can negatively affect the swimmer's technical ability and consequently increase drag forces [5].…”
