The Claim

Creatine monohydrate supplementation at 10 g/day for six weeks in junior female wrestlers has no significant effect on resting heart rate or fat-free mass, with physiological effects limited to increases in body weight, strength, power, and muscle size without additional impact on cardiovascular or lean mass metrics beyond water retention.

Description
1 study reviewed
In plain English

Taking 10 grams of creatine monohydrate daily for six weeks does not change resting heart rate or fat-free mass in junior female wrestlers. The supplement affects body weight, strength, power, and muscle size, but does not alter cardiovascular function or lean mass beyond water retention.

See the scientific wording

Creatine monohydrate supplementation (10 g/day) for six weeks in junior female wrestlers did not significantly alter resting heart rate or fat-free mass, indicating that the supplement’s physiological effects are limited to body weight, strength, power, and muscle size without impacting cardiovascular or lean mass metrics beyond water retention.

Why this might work

Creatine enters muscle cells and gets converted into a storage form that quickly replenishes energy during intense workouts. This lets muscles work harder and longer, which makes them grow bigger and stronger. The extra weight comes from water drawn into muscles and the added muscle tissue, but nothing else changes in the body like heart rate or lean mass beyond that.

  1. Study: Effects of Short-Term Creatine Monohydrate Supplementation Combined with Strength Training on the Physical Fitness Characteristics and Muscle Hypertrophy in Junior Women Wrestlers

    Taking creatine for six weeks made the wrestlers heavier and stronger, but didn’t change their heart rate or the actual amount of muscle tissue beyond what you’d expect from gaining muscle and water. So yes, the weight gain is mostly from water and muscle, not other body changes.
