Shoulder Internal Rotator Strength as Risk Factor for Shoulder Pain in Volleyball Players
Int J Sports Med DOI: 10.1055/a-1806-2303The aim of this study was to identify the intrinsic factors that could increase
risk of shoulder pain in adolescent volleyball players. Twenty-eight young male
volleyball players (between 14 and 18 years old) participated in this study.
Athletes were submitted to: isokinetic muscle strength assessment of shoulder
rotator muscles, ball service speed assessment, anterior and posterior drawer
test, apprehension test, groove sign and scapular dyskinesia test. Athletes were
followed for 16 weeks to monitor the presence of shoulder pain. All athletes
were submitted to the same training protocol. During the 16 weeks, 28.5%
of the athletes (n=8) experienced shoulder pain in the dominant limb
higher than 3 according to Numerical Rating Scale criteria; 71.5% of the
athletes (n=20) did not experience pain, or pain equal or lower than 3.
The main result of our study was that the odds of feeling pain higher than 3 was
significantly higher among players who presented higher values for internal
rotation peak torque (OR=1.113, CI 95%=1.006 to 1.232
and p=0.038). The odds of feeling pain increased by 11% for
every N·m of the internal rotator muscles. Pre-season isokinetic rotator
strength assessments can help identify adolescent volleyball players at
increased risk of a shoulder injur...
