Effect of hamstring stretching on hamstring muscle performance pdf

A centimetre scale is printed on the top surface of the box. The 15 cm line is approximately flush with the location of the toes below the overhang of the box. Having obtained the best sit and reach score cm per subject, the percentage change from the value before treatment was calculated. The null hypothesis was that a single massage treatment to the hamstring muscle group would have no effect on sit and reach performance immediately after treatment. The alternative hypothesis was that a single massage treatment to the hamstring muscle group would result in a change in sit and reach performance after treatment.

Table 1 shows the sit and reach scores cm for all 11 subjects for each of their massage or no massage visits. Figures 2 and 3 show the percentage changes in the scores as functions of their respective pretreatment values, for massage and no massage treatments respectively. The 15 cm toe line boundary is indicated on each figure.

Mean SD percentage changes in sit and reach scores after massage and no massage were small 6. Mean percentage changes in sit and reach scores after massage or no massage for subjects with relatively low reaches below 15 cm before treatment were considerably larger Percentage changes in pretreatment sit and reach scores are plotted against corresponding pretreatment values for the massage treatment.

The vertical line indicates the 15 cm toe line boundary separating the subgroups for statistical comparison. Percentage changes in pretreatment sit and reach scores are plotted against corresponding pretreatment values for the no massage treatment. The results of this study suggest that a single massage of the hamstring muscle group does not significantly alter sit and reach performance. However, the results also seem to indicate that percentage changes in sit and reach scores may be inversely proportional to pretreatment values.

The percentage changes in sit and reach scores were relatively small for those with pretreatment values of 15 cm and above—that is, those with relatively long reaches to begin with. This could have been important for the subjects with high reach scores who were perhaps not limited by hamstring muscle resistance in the first place. For all subjects with relatively low reach scores below 15 cm before treatment, massage was associated with an increase in reach, supporting the results of Crosman et al.

Wiktorsson-Moeller et al 5 found that massage alone or in combination with a warm up did not significantly increase any lower extremity ranges of motion, except for the ankle joint dorsiflexion. They found stretching to be the most effective way to improve flexibility in all of the lower extremity joints.

Larger subject pools would be required to explore these ideas further. Take home message A single massage of the hamstring muscle group seems to have little effect in people who already have good hip joint flexibility.

However, those with poor hip joint flexibility may significantly benefit from a one off hamstring massage. Larger subject numbers would be useful in clarifying these results and ideas.

Statistics from Altmetric. Procedures Subjects were randomly assigned to attend two test sessions each, separated by one week, wherein they would receive either a specific hamstring muscle group massage to both legs by a qualified massage therapist or supine rest.
