Optimisation of isometric strength training intensity.

The aim of this study was to determine the optimal intensity for isometric strength training. Isometric elbow flexor strength of 51 subjects was measured before and after a six-week training period. Subjects were randomly assigned to target training intensities between 0 and 100 per cent of a maximal voluntary contraction, and undertook supervised isometric elbow flexor training at the allocated target intensity three times each week for six weeks.

Background And Purpose: The aim of this study was to evaluate the efficacy of a physical therapy approach to the treatment of shoulder pain. Subjects. Sixty-six volunteers with shoulder pain believed to be of local mechanical origin were randomly allocated to either a treatment group or a control group.
