Non-local Acute Passive Stretching Effects on Range of Motion in Healthy Adults: A Systematic Review with Meta-analysis

Stretching a muscle not only increases the extensibility or range of motion (ROM) stretched joint but there is growing evidence increased ROM contralateral and other non-local muscles joints. The objective this meta-analysis was to quantify crossover changes in passive following an acute bout unilateral stretching examine potential dose–response relations. Eleven studies involving 14 independent measures met inclusion criteria. included moderating variables such as sex, trained state, intensity duration. analysis revealed that static induced moderate magnitude (standard mean difference within studies: SMD: 0.86) with non-local, non-stretched Moderating intensity, duration did results. Although present statistically significant differences, greater than 240-s (SMD: 1.24) exhibited large compared improvements shorter (< 120-s: 0.72) durations stretching. Passive one group can induce magnitude, global ROM. 240 s may have larger effects durations.
