Abstract
[Purpose] Although a correlation has been reported between shoulder strength and maximum
swimming power during arm-only swimming, the correlation between shoulder strength and
maximum swimming power during front crawl swimming remains unclear. This study aimed to
confirm the validity of a clinical assessment method for shoulder strength related to
front crawl swimming power. [Participants and Methods] Study participants included 9
healthy male collegiate swimmers. Shoulder strength, including extension and internal
rotation torque and swimming power, were measured. [Results] Maximum swimming power was
significantly correlated with extension torque in the position of maximum shoulder
abduction on the dominant side (r=0.844). No significant correlations were observed
between the swimming velocity-to-swimming power ratio and the rate of bilateral
differences in extension torque in the position of maximum shoulder abduction.
[Conclusion] The extensor strength in the position of maximum shoulder abduction was
significantly correlated with the maximum swimming power, suggesting that this assessment
method is useful for front crawl swimmers. Notably, measurements on the dominant side may
provide useful data that are essential in training to improve front crawl swimming
propulsion.
