简要总结
Stretching is reported to decrease muscle strength and thus suggested to be avoided prior to athletic events but with conflicting reports. This time course study aimed to assess acute effects of static stretching of different durations on isometric maximum voluntary contraction force of calf muscle.
详细描述
Stretching is reported to decrease muscle strength and thus suggested to be avoided prior to athletic events but with conflicting reports. This time course study aimed to assess acute effects of static stretching of different durations on isometric maximum voluntary contraction force of calf muscle. Pretest posttest experimental design was used. 14 subjects participated in three experimental trials: Static stretching for 2 minutes (SS2), static stretching for 4 minutes (SS4), and static stretching for 8 minutes (SS8). Strength was measured before (pre), immediately after (post), and at 10- and 20- minutes post stretching. Each static stretching (SS) trial involved varied repetitions of 30-seconds self-stretches and 20-seconds relax periods.
