The effects of 3 weeks of voluntary running training on NR4A3, PGC-1α, and COX I protein levels in rat triceps muscles
| Sedentary | Voluntary running | |
|---|---|---|
| NR4A3 | 1.00 ± 0.05 | 1.02 ± 0.09 |
| PGC-1α | 1.00 ± 0.15 | 1.49 ± 0.15* |
| COX I | 1.00 ± 0.15 | 1.58 ± 0.20* |
Relative protein levels are expressed as mean ± SE for 6–7 muscles/group
Significant differences from sedentary control, * P < 0.05
