The Claim

In young, physically active men, eight weeks of low-intensity strength training without muscle relaxation (LISTR) at reduced loads produces similar increases in maximum voluntary force as classical strength training (CST) at higher loads, while preserving local muscular work capacity.

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

In plain English

In young, physically active men, eight weeks of low-intensity strength training with continuous tension produces the same increase in maximum strength as higher-intensity training, while maintaining the ability to sustain muscular effort.

See the scientific wording

In young, physically active men, eight weeks of low-intensity strength training without muscle relaxation (LISTR) at reduced loads produced similar increases in maximum voluntary force as classical strength training (CST) at higher loads, while preserving local muscular work capacity, suggesting that continuous tension during movement may maintain endurance despite lower mechanical stress.

Why this might work

Keeping muscles under constant tension during lifting, even with light weights, forces the body to activate more muscle fibers and use energy more efficiently, which builds strength without making the muscles tired as fast.

  1. Study: Physiological effects of low-intensity strength training without relaxation

    In young men, lifting lighter weights without relaxing your muscles between reps built strength just as much as lifting heavy weights, but didn't make your muscles tire out as quickly.
