Effects of static and dynamic stretching techniques on muscle function.
Kouichi Nakamura, Sota Nakano, Daisuke Tsuchikawa
PMID 40034557WHAT IT FOUND
Combining static and dynamic hamstring stretches improved range of motion significantly, but did not increase muscle output.
The order of stretching did not change these results.
Key findings
01Both static and dynamic stretching sequences significantly improved hip flexion range of motion.
02Neither sequence produced a statistically significant increase in hamstring muscle output.
03There were no significant differences between groups when comparing the extent of change in range of motion or muscle output.

What it does not show
The study included only 32 healthy young adult males, so results may not apply to older adults, females, or patients with pathology. The sample size was small, which may explain why the observed increase in muscle output did not reach statistical significance. The study measured immediate effects only; it did not assess long-term changes in function or injury risk.
Declared interests
There are no conflicts of interest to disclose, and the research received no funding.
The easy way to misread this
Do not assume that dynamic stretching alone is superior for muscle output or that static stretching ruins performance. Neither sequence significantly increased muscle output in this study, and the order of stretching did not change the outcome.
