The Claim

Twelve weeks of isotonic resistance training increases isokinetic peak torque at 60°·s⁻¹ by 13–32% in young healthy males, regardless of contraction modality or velocity, suggesting that strength gains transfer to moderate-speed muscle performance.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Supports
47score
Challenges
0score

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

If young, healthy guys lift weights for 12 weeks, their muscles get stronger at moderate speeds — like kicking or swinging — and they can generate 13% to 32% more force, no matter how they did the lifting.

What the research says

1 study

  1. Study: Comparison of the Effects of Eccentric, Concentric, and Eccentric-Concentric Isotonic Resistance Training at Two Velocities on Strength and Muscle Hypertrophy.

    The study had guys do different types of leg exercises for 12 weeks and found that all of them got stronger at moderate speeds, no matter how they did the exercises — which is exactly what the claim says.
