Conclusion
SGA had a greater effect on IR than ER muscle strength,
likely creating a muscle imbalance in the shoulder joint,
which may predispose this to a higher injury risk. These
findings may be helpful to exercise and sports science
professionals since improving IR muscles endurance may
prevent muscular imbalance at end of games. Despite this
muscle strength reduction, ball velocity was not affected.
Functional strength ratio had a negative correlation with
ball velocity. However, muscular imbalance should be discouraged
because of the increased risk of injury.
Ethics approval
Participants were informed of the potential risks and
benefits of the study and signed an informed consent
form to take part. All experimental procedures were approved
by the Federal University of São Paulo Human
Research Ethics Committee and conformed to the principles
outlined in the Declaration of Helsinki.
