Effects of dynamic and static stretching within general and activity specific warm-up protocols

The purpose of the study was to determine the effects of static and dynamic stretching protocols within general and activity specific warm-ups. nine male and ten female subjects were tested under four warm-up conditions including a 1) general aerobic warm-up with static stretching,2) general aerobic warmup with dynamic stretching,3) general and specific warm-up with static stretching and 4) general and specific warm-up with dynamic stretching. following all conditions,subjects were tested for movement time (kicking movement of leg over 0.5 m distance),countermovement jump height,sit and reach flexibility and 6 repetitions of 20 metre sprints. results indicated that when a sport specific warm-up was included,there was an 0.94% improvement (p = 0.0013) in 20 meter sprint time with both the dynamic and static stretch groups. no such difference in sprint performance between dynamic and static stretch groups existed in the absence of the sport specific warm-up. the static stretch condition increased sit and reach range of motion (rom) by 2.8% more (p = 0.0083) than the dynamic condition. these results would support the use of static stretching within an activity specific warm-up to ensure maximal rom along with an enhancement in sprint performance. © journal of sports science and medicine.
