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.

Detailed description

OBJECTIVE: 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. DESIGN: Two-group pretest-posttest experimental design. METHODS: Each subject visited the Rehabilitation center on three days: On day-I for static stretching for 2 minutes (SS2), day-II for 4 minutes (SS4), and day-III for 8 minutes (SS8). Isometric Maximum Voluntary Contraction Force (MVCF) measurement was done prior (Pre), 0-min, 10-min, and 20-min post-intervention (i.e. stretching). Each visit was separated by a gap of at least 3-4 days. On each visit, each subject underwent (a). Pre-intervention evaluation, (b). Intervention, (c). Post-intervention evaluation. Subjects performed stretching exercises under the supervision of expert Physical Therapist. The outcome assessor who was kept blind to study protocol did all measurements.
