Figure 1: Effects of training on running performance and GM force characteristics of the rats. Effects of peak power training alone (PT) and peak power training in combination with endurance training (PET) on (a) maximum running velocity, (b) maximal force ( ), and (c) force-velocity and power-velocity curves of the rat medial gastrocnemius muscle. Forces as a function of contraction velocity were significantly higher after PT compared to those of controls. Symbols (control: white diamond, PT: black triangle, PET: black circle) on the force velocity curve indicate the isometric and symbols on the power curve indicate maximal peak power at optimum shortening velocity. All values are mean ± SE. *= significant difference between the groups ( ); §= significantly different from control ( ).
