The Claim
A single session of stretching immediately before physical activity acutely impairs muscle strength and, to a lesser extent, muscle power in individuals engaged in sports or exercise, suggesting that pre-exercise stretching may temporarily reduce strength capacity.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Stretching right before sports or workouts might make your muscles weaker for a short time, especially when it comes to strength.
See the scientific wording
A single bout of stretching acutely impairs muscle strength, with a smaller negative effect on muscle power, in individuals engaging in sports or physical activity, suggesting that stretching immediately before performance may temporarily reduce strength capacity.
What the research says
1 studyStudy: To stretch or not to stretch: the role of stretching in injury prevention and performance
The study says that stretching right before sports can temporarily reduce strength, with a smaller effect on power, which matches the claim.
