Effects of Repetitive Handgrip Training on Endurance, Specificity, and Cross–Education

Exercise programs are more likely to be successful when they are based on research that predicts the outcomes of such training. This study determined the effect of submaximal rhythmic handgrip training on rhythmic handgrip endurance or work (RHW), isometric handgrip endurance time (IHE), and maximal voluntary isometric contraction for the handgrip force (MVIC) (in newtons). Twenty-four male subjects (mean age=26.2 years) with right-hand dominance were randomly assigned to a regular training group (n=8), a low-level training group (n=8), or a control group (n=8). Rhythmic handgrip work, IHE, and MVIC were determined bilaterally before and after 6 weeks of a rhythmic right handgrip training program using 30% of MVIC. The low-level training group performed daily training with a near-zero load (
