The Claim
Creatine supplementation combined with resistance training for at least 12 weeks increases one-repetition maximum (1RM) strength by an average of 2.12 kg in adults aged 55 and older.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults aged 55 and older, taking creatine supplements along with resistance training for 12 weeks results in an average increase of 2.12 kg in one-repetition maximum strength.
See the scientific wording
Creatine supplementation combined with resistance training for at least 12 weeks increases one-repetition maximum (1RM) strength by an average of 2.12 kg in adults aged 55 and older, indicating a moderate improvement in muscle strength that may help counteract age-related sarcopenia.
Creatine builds up in muscle cells and helps make more energy quickly during hard exercise. This lets a person do more reps and lift heavier weights, which signals muscle cells to grow larger and make more contractile proteins. Bigger muscles produce more force, which shows up as a higher one-repetition maximum.
What the research says
1 studyTaking creatine along with strength training for several months helped older adults lift about 2 kg more weight on average, which means they got stronger. This can help them stay more mobile and reduce fall risk.
