Experimental approach to the problem
The participants took part in four experimental sessions within 4 weeks. The experimental sessions were performed in a randomized order, 1 week apart, where each participant performed: (i) 5 sets of 30 s calf raises on the platform but without vibration (CTRL); (ii) 5 sets of 30 s calf raises on the vibration platform with 30 s rest intervals between sets (WBV); (iii) 5 sets of 6 drop jump with a 30 s rest interval between sets (DJ); iv) 5 sets of 30 s calf raises on the vibration platform followed by 6 drop jumps with a 30 s rest interval between sets (WBV + DJ). To examine the acute effects of each conditioning protocol on subsequent countermovement jump height a single-sets of 2 repetitions of the CMJ were performed before, 3-min after, and immediately after a 3 km run (Fig. Study design flowchart.
