The Claim

A daily protein intake of approximately 1.08 g/kg in middle-aged men does not restore muscle function within 72 hours after damaging eccentric exercise, and protein intakes of 1.2–1.6 g/kg are required for restoration of muscle function within this timeframe.

Cause and effect
1 study reviewed
In plain English

Middle-aged men who consume about 1.08 grams of protein per kilogram of body weight daily do not recover muscle function within 72 hours after intense eccentric exercise. Recovery requires a higher protein intake between 1.2 and 1.6 grams per kilogram of body weight.

See the scientific wording

Daily protein intake of approximately 1.08 g/kg in middle-aged men is insufficient to restore muscle function within 72 hours after damaging eccentric exercise, suggesting higher intakes (1.2–1.6 g/kg) may be necessary for recovery.

Why this might work

When muscles are damaged by intense exercise, the body needs more protein to rebuild broken fibers and restore strength. If not enough protein is eaten, the repair process slows down, leaving muscles weak and sore for days.

  1. Study: Effects of Pre-Sleep Whey vs. Plant-Based Protein Consumption on Muscle Recovery Following Damaging Morning Exercise

    Middle-aged men who ate about 1.1 grams of protein per kilogram of body weight each day still felt weak and sore three days after intense exercise, no matter if they drank protein shakes or water. This suggests they needed more protein to recover properly.
