The Claim

In trained male futsal players not performing resistance training, daily protein intake exceeding 1.6 g/kg body weight, with additional protein supplementation regardless of source, has no significant effect on body composition or performance outcomes over an 8-week period.

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

Cause and effect
1 study reviewed
In plain English

For trained male futsal players who are not doing weight training, consuming more than 1.6 grams of protein per kilogram of body weight per day, even with extra protein supplements, does not change body composition or athletic performance after 8 weeks.

See the scientific wording

When daily protein intake exceeds 1.6 g/kg body weight in trained male futsal players not performing resistance training, additional protein supplementation—regardless of source—does not significantly alter body composition or performance outcomes over 8 weeks.

Why this might work

When the body gets more protein than it needs for repair and maintenance, it stops using the extra for building muscle or improving performance. The muscles can only process so much protein at a time, and any surplus is broken down and used for energy or stored as fat, without changing body shape or athletic ability.

    For futsal players who already eat enough protein, adding more protein—whether from milk or plants—doesn’t make them stronger, faster, or more muscular over eight weeks if they’re not lifting weights.
