Sets | Duration | Rest | Wave frequency | Force | |
Weeks 1–4 | 3 (excluding the warm-up) | 60 s for each sinusoidal frequency | 30 s between each set (including the warm-up) | Slow (0.05 Hz), medium (0.08 Hz) and fast (0.14 Hz) randomly ordered | 20%–50% of MVIC. MVIC re-assessed at the beginning of each session |
Weeks 5–6 | 3 (excluding the warm-up) | 90 s for each sinusoidal frequency | 30 s between each set (including the warm-up) | Slow (0.05 Hz), medium (0.08 Hz) and fast (0.14 Hz) randomly ordered | 20%–50% of MVIC. MVIC re-assessed at the beginning of each session |
Weeks 7–8 | 3 (excluding the warm-up) | 120 s for each sinusoidal frequency | 30 s between each set (including the warm-up) | Slow (0.05 Hz), medium (0.08 Hz) and fast (0.14 Hz) randomly ordered | 20%–50% of MVIC. MVIC re-assessed at the beginning of each session |
Weeks 9–12 | 3 (excluding the warm-up) | 120 s | 30 s between each set (including the warm-up) | Each set will contain a random mixture of each frequency (slow, medium, fast) | 20%–50% of MVIC. MVIC re-assessed at the beginning of each session |
Hz, hertz; MVIC, maximum voluntary isometric contraction.
