Girls stretching on the field

Do you like to stretch before going for a run? Research shows that short durations of dynamic stretching (up to 4 minutes) are the most beneficial for running performance if there are no further warm-up activities after stretching. Static stretching, on the other hand, has no effect on performance but can reduce acute injuries by up to 54%.
