The Claim

Muscle hypertrophy demonstrates regional heterogeneity within a single muscle group, with distal muscle regions exhibiting potentially greater growth responses compared to proximal regions when subjected to specific exercise interventions.

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.

Description
1 study reviewed
In plain English

When you work out, different parts of the same muscle can grow at different rates. Some exercises might make the far ends of your muscles grow more than the middle parts.

See the scientific wording

Muscle hypertrophy is non-uniform across different regions of the same muscle group, with distal regions potentially growing more than proximal regions from certain exercises.

What the research says

1 study
  1. Study: The role of exercise selection in regional Muscle Hypertrophy: A randomized controlled trial

    The study compared two different leg exercises and found that some exercises made all parts of a muscle grow, while other exercises only made certain parts grow. This proves that muscle growth isn't the same everywhere in a muscle - it depends on which exercise you do.
