In junior female wrestlers, taking 10 grams of creatine daily for six weeks along with strength training did not change body fat or lean muscle mass, meaning any weight gain was likely from other factors like water retention.

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

Randomized Controlled Trial

Human

The study found that wrestlers who took creatine and trained got heavier and their muscles grew bigger, which means the weight gain was likely from muscle, not just water or fat. This contradicts the claim that muscle didn’t increase.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

In junior female wrestlers, taking 10 grams of creatine monohydrate daily for six weeks along with strength training led to an increase in body weight and BMI, but this was due to water retention, not an increase in fat or muscle mass.

In young female wrestlers aged 18–19, taking 10 grams of creatine monohydrate daily on training days along with strength training leads to measurable increases in maximum strength and muscle size in the chest, arms, thighs, and calves, while strength training without creatine does not produce significant changes in these measures.
