The Claim

Resistance exercise performed to muscular failure induces greater acute decreases in countermovement jump height compared to non-failure exercise in recreationally strength-trained adults aged 18-33, indicating more pronounced neuromuscular performance impairment immediately following training.

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 people who regularly lift weights push their muscles until they can't do any more reps, their ability to jump high drops more right after than if they stopped before getting tired. This means their muscles and nerves are more worn out.

What the research says

1 study
  1. Study: Acute effects of muscle failure and training system (traditional vs. rest-pause) in resistance exercise on countermovement jump performance in trained adults

    The study found that when people lift weights until they can't anymore, their jump height drops more right after compared to when they stop before failure, which matches the claim exactly.
