|---|---|---|---|
| Run | Gluteals | 16.5 (6.5) | 14.4 (4.6) |
| Vasti | 20.3 (7.7) | 16.5 (5.8) | |
| Hamstrings | 13.4 (4.2) | 12.6 (5.5) | |
| Cycle | Gluteals | 17.4 (6.8) | 16.7 (5.7) |
| Vasti | 13.7 (5.4) | 15.1 (5.9) | |
| Hamstrings | 13.2 (4.1) | 17.4 (6.8) * | |
| Squat | Gluteals | 13.7 (5.2) | 12.5 (5.5) |
| Vasti | 9.8 (4.4) | 8.3 (3.3) | |
| Hamstrings | 8.8 (4.7) | 10.4 (4.6) | |
* denotes higher variability in the textile vs. traditional surface EMG electrodes
