The Claim
Conventional resistance training provides calf muscle hypertrophy and strength adaptations with significantly greater time efficiency (approximately 45 minutes weekly) compared to long-lasting static stretching (up to seven hours weekly) in recreational athletes.
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.
If you want bigger, stronger calves, lifting weights is much faster than just stretching. You only need about 45 minutes a week with weights to get the same results that would take over seven hours of stretching.
See the scientific wording
The practical application of long-lasting static stretching for inducing calf muscle hypertrophy and strength is strongly limited by its low time efficiency, requiring up to seven hours of weekly stretching to achieve adaptations comparable to conventional resistance training, which typically requires only approximately 45 minutes of weekly exercise, making the latter a far more time-efficient intervention for recreational athletes.
What the research says
1 studyThe study found that stretching your calves for an hour every day works just as well as weightlifting for building muscle and strength, but it takes much longer (7 hours a week vs. 45 minutes), making weightlifting the faster option.
