Weight training exercise and static stretching: a longitudinal study

Does Stretching Training Influence Muscular Strength? A Systematic Review With Meta-Analysis and Meta-Regression

“…The systematic literature search identified 12,622 potential articles; of which, 35 were included (1–3,8,13,16,18,19,29,35,38–43,48–51,56,58,61,64–66,68,69,76,79–82,91,92). The included studies, composed of 1,055 individuals ( n total = 1,179; control: n = 545, stretching: n = 634 [including each limb on intra-subject design studies]; mean age = 24.0 ± 3.2 year-old), applied stretching as a unique form of intervention ( n = 21) (1–3,13,16,39,41–43,49,51,56,58,61,65,66,68,76,80,82,92), as a combination of RT and stretching ( n = 12) (8,18,19,29,35,38,40,48,50,64,81,91) or both ( n = 2) (69,79). All studies applied stretching on the lower body involving plantar flexors, knee eor hip extensors and flexors, except two, shoulder horizontal flexors and extensors (82), and shoulder adductors (91), which performed stretching on the lumbar spine extensors.…”

“…All studies applied stretching on the lower body involving plantar flexors, knee eor hip extensors and flexors, except two, shoulder horizontal flexors and extensors (82), and shoulder adductors (91), which performed stretching on the lumbar spine extensors. Six studies also applied stretching in the upper body, involving the elbow extensors and shoulder adductors (8,18,29,50,69,79). The most frequent form of stretching intervention was static stretching, although PNF (13,41,56,76), dynamic (3,19,50), and ballistic (42,49) modalities were also performed.…”

“…The timing of the stretching application to RT varied between the studies included herein. Stretch exercises were included before RT (8,19,35,48,50,79), in the inter-RT-set rest period (8,18,29,64,82,91), after RT (38,48,50,69), or on alternate days (40). The only study that compared distinct timings was that of Leite et al (50), where authors examined stretching before or after RT sessions in comparison to an RT-only condition.…”
