Fig. 1. Sample recordings of the ground reaction torque (A) and angular power (B) applied during maximum-effort jump turns by subject ‘B’. The thick lines denote the recording obtained when the subject turned with his rotational inertia elevated 9.7-fold (Table 1) above that of the weight-controlled jump (shown by the thin line). Note that subject B did more angular work (i.e. area under the angular power curves) in the increased rotational inertia trials than in the control trials (Table 5).
