3.3. Flexibility and Differences by Age
3.3.1. Shoulder Abduction. The mean range of motion of
shoulder flexibility was 138 degrees in our sample, with no
difference between men and women. Shoulder abduction
showed a significant decline across age, averaging 5 degrees
per decade in men and 6 degrees per decade in women. From
piecewise linear regression, an accelerated decline of 0.80
degrees per year was observed in the sample of men starting
