Effect of massage of the hamstring muscles on selected electromyographic characteristics of biceps femoris during sub-maximal isometric contraction.

The aim of this study was to investigate whether a single massage of the hamstring muscles would alter selected electromyographic characteristics of biceps femoris during a sub-maximal isometric contraction. Eleven healthy young males participated in this crossover study. They were randomly assigned to two groups, receiving either a 15-minute hamstring muscle massage or a 15-minute prone rest.

Effect of massage of the hamstring muscle group on performance of the sit and reach test.

Objective: To investigate if a single massage of the hamstring muscle group would alter the performance of the sit and reach test.

Methods: Before treatment, each of 11 male subjects performed the sit and reach test. The treatment consisted of either massage of the hamstring muscle group (both legs, total time about 15 minutes) or supine rest with no massage.
