The Claim

In resistance-trained female collegiate athletes, a 4-day per week undulating resistance training program combined with 24 grams of protein consumed before and after each training session over eight weeks causes significant improvements in lower-body strength, specifically increasing leg press one-repetition maximum by approximately 89–90 kg on average.

Source: The effect of resistance training combined with timed ingestion of protein on muscle fiber size and muscle strength.

What the research says

Supports is higher

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

Supports

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.

Cause and effect
1 study reviewed
In plain English

If female college athletes who already lift weights add a specific workout plan and eat 24 grams of protein before and after each session, they’ll get way stronger in their legs—adding about 90 kg to their leg press max in just eight weeks.
