Tendon histology. Exercise did not affect cell density (A and B). Cells were rounder, 48 h after a single bout of exercise (C) and after 3 days and 1, 2, and 8 wk of chronic exercise (D). One-way ANOVA for acute time points and separately for early chronic time points, followed by Fisher’s LSD pairwise comparisons when ANOVA was significant. Student’s t-test was used to compare 8 wk time point. Means and SD are shown; n = 6–8 acute, 6–9 chronic.
