Brief Summary

Muscular flexibility is believed to prevent injuries and improve movement therefore most coaches include stretching exercises in their pre-competition and pre-exercise warm-up routines. One question arises here, should sports persons avoid stretching exercises prior to sporting events thereby exposing themselves to musculoskeletal injuries, or should they continue stretching exercises prior to sporting events and risk losing the maximal performance? The aim of this study is to compare the effects of 2, 4, and 8 min of static stretching (SS) on isometric maximum voluntary contraction (MVCF) force between proximal (Hamstrings) and distal group (Calf) of muscles.

Conditions

STRETCHING

Keywords

Muscle strength; muscle stretching exercises; strain gauge

Outcome Measures

Primary Outcomes (1)

• Change in isometric maximum voluntary contraction force before and after stretching

  Change in isometric muscle strength measured before and after stretching using strain gauge on 3 different days

  MVCF was measured immediately (0 min), 10-min and 20 min post intervention on 3 different days, with each day separated by gap of 3-4 days.

Study Arms (2)

Group A (Hamstrings)

EXPERIMENTAL

Hamstring stretching would be done then isometric strength would be measured.

Other: Muscle static stretching

Group B (Calf)

EXPERIMENTAL

Calf stretching would be done then isometric strength would be measured.

Other: Muscle static stretching

Interventions

Muscle static stretching OTHER

On day-I: Static Stretching done for 2 minutes (SS2), on day-II: Static Stretching done for 4 minutes (SS4), and on day-III: Static Stretching done for 8 minutes (SS8).

Group A (Hamstrings); Group B (Calf)

Eligibility Criteria

• Age: 22 Years - 30 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• For group A: subjects performed active knee extension test and those lacking at least 20 degrees of active knee extension range, with hip in 90 degree of flexion were selected. For group B (Calf): Subjects performed active foot dorsiflexion in long sitting position with back supported against the wall and those having not more than 20-degree range of motion were selected.
• Selected subjects used to engage in 1-5 hours of regular physical activity per week (recreationally active) that does not involve stretching exercise

You may not qualify if:

• Subjects reporting any current or ongoing neuromuscular disease, injury specific to lower limb joints, any apparent limit in knee or ankle ROM and competitive/professional athletes were excluded from study.
