Acute effects of static and dynamic stretching on agility and movement time of high school students

What is it about?

The study compared the acute effects of three warm-up protocols on change-of-direction speed, reaction time, and movement time of upper extremities. All participants performed the following warm-up protocols on three different days: (a) 3 min. jogging followed by 5 min. static stretching, (b) 3 min. jogging followed by 5 min. dynamic stretching, and (c) 3 min. jogging followed by 5 min. of rest without stretching. At the end of each protocol, participants performed sprints of moderate to submaximal intensity. After the warm-up protocols, participants performed the following tests: “505-change-of-direction-speed,” reaction time, and movement time (arm movements). There was no significant effects of protocols on the performance tests.

Why is it important?

Pre-exercise stretching may not be required for performance improvement in activities involving change-of-direction speed, reaction, and movement time if the final part of the warm-up involves sprinting.
