The Study
Effects of Short-Term Creatine Monohydrate Supplementation Combined with Strength Training on the Physical Fitness Characteristics and Muscle Hypertrophy in Junior Women Wrestlers
This study gave some wrestlers creatine and others didn’t, then saw who got stronger and bigger. It shows that the group with creatine improved more — but we can’t be sure it was the creatine alone, because everyone who got creatine also trained, and the group that didn’t get creatine didn’t train at all.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
Some wrestlers took a powder called creatine every day while training, others trained without it. The ones who took creatine got stronger, faster, and jumped higher.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — these improvements are meaningful for athletes who need quick bursts of strength and speed, like wrestlers.
- 2Creatine group: 8.4% stronger, 12.2% more powerful, 4.5% faster in agility tests.
- 3Weight went up, but not from fat or muscle.

Junior female wrestlers who took 10 grams of creatine monohydrate daily for six weeks while doing strength training showed a 12.2% improvement in muscular power on the Sargent jump test, compared to those who only did strength training.
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.
Taking creatine supplements leads to greater muscle strength and increased muscle mass in humans by boosting the availability of phosphocreatine to regenerate ATP.
Junior female wrestlers who took 10 grams of creatine monohydrate daily for six weeks while doing strength training showed a 4.5% improvement in agility test scores, while those who only did strength training did not show a significant change.
In female wrestlers aged 18–19, taking 10 grams of creatine monohydrate daily on training days for six weeks along with strength training increased one-repetition maximum strength by 8.4%, improved agility by 4.5%, and increased muscular power by 12.2% compared to strength training alone.
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.
