The Claim

Low-load resistance training at 30% of one-repetition maximum performed to volitional fatigue for 10 weeks increases mitochondrial proteins related to autophagy, fission, and fusion in untrained young men, suggesting enhanced mitochondrial turnover and function specific to high-volume training.

Source: Resistance Exercise-induced Changes in Muscle Metabolism are Load-dependent.

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.

Cause and effect
1 study reviewed
In plain English

When untrained young men lift lighter weights until they get tired for 10 weeks, their cells get better at cleaning up and renewing their energy factories, which helps them handle lots of exercise.

What the research says

1 study
  1. Study: Resistance Exercise-induced Changes in Muscle Metabolism are Load-dependent.

    The study did exactly what the claim said: it had young men lift lighter weights until tired for 10 weeks and found their muscles improved how they handle energy parts, just like the claim predicted.
