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.

In plain English

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.

Why this might work

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.

  1. Study: Impact of creatine supplementation and exercise training in older adults: a systematic review and meta-analysis

    Taking 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.
