 One group did the explosive contractions, one group did the sustained contractions, and a third group acted as a control group. The participants trained with 40 contractions repeated three times a week for three months. The force produced by every contraction was prescribed and monitored to ensure it was either explosive or sustained. An extensive range of performance and physiological measurements were done before and after the training to assess the changes.
