From: Effect of acute exercise on patella tendon protein synthesis and gene expression
Geometric mean (± back-transformed SEM) of TGF-β-1 (A), CTGF (B), COL1A1 (C), COL3A1 (D), GAPDH (E) mRNA, normalized to RPLP0 mRNA, in Control (no bars) and Exercise (grey bars). All data are presented as fold changes between the two groups. That is the changes relative to the mean of all control values. Data were analyzed with unpaired and two-tailed t-tests. For TGF-β-1 (p = 0.34), no difference between groups was observed. Significant higher CTGF and COL1A1 mRNA levels were observed in the exercise group compared to the control group (p < 0.05). For COL3A1 (p = 0.11), the difference between groups was not significant. Control: no exercise; Exercise: 1-hr unilateral kicking at 67% of maximal workload 24 hours before trial.
