The Claim
Daily extended static stretching of the calf muscles for one hour is associated with increased ankle dorsiflexion range of motion and enhanced joint mobility in recreationally active adults, with flexibility improvements comparable to those achieved through six weeks of hypertrophy-focused resistance training.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Spending an hour a day stretching your calves can make your ankles more flexible, giving you the same mobility benefits as doing heavy leg workouts for six weeks.
See the scientific wording
Extended static stretching protocols involving one hour of daily calf muscle elongation are associated with improved ankle dorsiflexion range of motion in recreationally active adults, producing flexibility gains that are statistically equivalent to those observed following a standard hypertrophy-focused resistance training regimen over six weeks, indicating that prolonged passive tension can effectively enhance joint mobility.
What the research says
1 studyThe study found that stretching your calves for an hour every day for six weeks improved your ankle flexibility just as much as doing traditional weightlifting exercises, proving that long, gentle stretches are just as effective for gaining mobility as heavy lifting.
