Training protocol
The four groups completed the 6-week training programme in the same weight-training room, performing the following 4 lower limb exercises: leg press, alternative lunge, squat and front squat for 4 sets x 12 repetitions at 70% of repetition maximum (RM).
All sessions were documented, surveyed, and supervised by the investigators. The training of the control group was matched with the training of the WBV group; i.e. training duration, number of sets, rest periods and task-specific instructions were identical for both groups.
