Figure 4.

Bar graphs comparing relative changes of isometric maximum force from pretest to Posttest 1. The values shown are expressed as mean ± SE. Data from the different exercises are pooled within each experimental group (M0, M25, M50, M75). Note: one half of each group trained single-joint exercises (calf raise, triceps extension); the other half, multijoint exercises (leg press, bench press). Non-practiced exercises (multijoint or single-joint exercises) were taken as a control condition.
