The Claim

In resistance-trained female collegiate athletes, the consumption of 24 grams of protein both before and after resistance training sessions, as part of a structured eight-week program, causes significant improvements in upper-body strength, specifically increasing bench press one-repetition maximum by 4.3–7.5 kg, with greater gains observed with whey protein compared to casein protein.

Cause and effect

In plain English

If female college athletes who lift weights drink a protein shake with 24 grams of protein before and after workouts for eight weeks, they’ll get stronger in their upper body — especially if they use whey protein instead of casein.

See the scientific wording

In resistance-trained female collegiate athletes, consuming 24 grams of protein before and after resistance training sessions for eight weeks as part of a structured program causes significant improvements in upper-body strength, increasing bench press one-repetition maximum by 4.3–7.5 kg depending on protein type, with whey showing a statistically greater gain than casein.

What the research says

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

    The study found that both whey and casein helped female athletes get stronger in the bench press, but there was no clear proof that one worked better than the other.
