Abstract

The strength balance of the shoulder rotator between pairs of homologous muscles and between agonist and antagonist muscles is mainly important in activities involving overload of the upper body.

Purpose

The aim of the study was to compare the bilateral balance and ratio of shoulder rotator muscles between strength training practitioners with non-practitioners.

Methods

Ten adults who trained to strengthen for their upper limbs (STR) and ten untrained performed maximal isokinetic torque of internal and external rotators of shoulder in 90° protocol with a speed of 60° and 180°/s. The concentric torque peak and ratio between the internal and external rotators of the shoulder were evaluated. Factorial Anova was performed to weave the comparisons with significance level 0.05.

Results

The torque of internal rotators was higher for the group STR, while the external rotators did not differ between the two groups. In addition, ratios were higher between STR at a speed of 180°/s. No bilateral difference was observed in the application of torque in either group.

Conclusion

Emphasis on the external rotator is required for groups design to train muscle strength, as their ability to generate internal torques is larger than that required to produce external torques and, therefore, more prone to muscle imbalance.
