Flexible muscles may be stronger muscles
NEW YORK (Reuters Health) – Adults with tight leg muscles can improve their flexibility, and may make their muscles stronger in the process, a study shows.
Most physically active people probably do a little stretching or know that they should. But little research has been done on the correlation between muscle flexibility and muscle performance, according to the authors of the new study.
To look at this question, the researchers recruited 30 young adults with tight hamstrings, the muscles at the back of the thighs. For six weeks, the volunteers performed a series of hamstring stretches five days per week; at the beginning and end of the study, they had their flexibility and thigh muscle strength tested using workout equipment.
