Time Based Effects of Different Duration Stretching on Calf Muscle Strength

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.

About this study

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.

Who can participate

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Subjects performed active foot dorsiflexion in long sitting position with back supported against wall and those having not more than 20-degree range of motion were selected
  • Used to engage in 1 to 5 hours of physical activity per week

Exclusion criteria

  • Subjects having any current injury or limits in range of motion specific to lower limb joints
  • Current neuromuscular disease
  • Competitive athletes were excluded from the study

Treatment and study plan

Muscle Static Stretching

Other

Static stretching for 2 minutes (SS2), static stretching for 4 minutes (SS4), and static stretching for 8 minutes (SS8). Each static stretching (SS) trial involved varied repetitions of 30-seconds self-stretches and 20-seconds relax periods.

Primary outcomes

  1. Change in Isometric Maximum Voluntary Contraction Force

    Time frame: MVCF at baseline and 0, 10, 20-min post stretching

    Isometric Maximum Voluntary Contraction Force was measured using strain Gauge.
