The Claim

In young, weight-trained males undergoing daily heavy leg-extensor resistance training for two weeks, one repetition maximum (1 RM) leg press strength increases by approximately 6%, suggesting rapid neuromuscular adaptation to intensified resistance exercise.

Source: Changes in human skeletal muscle contractility and hormone status during 2 weeks of heavy strength training

What the research says

Supports is higher

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

Supports
39score
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.

Quantitative
1 study reviewed
In plain English

If young guys who already lift weights do intense leg workouts every day for two weeks, they get about 6% stronger in their leg press, showing their muscles and nerves adapt quickly.
