The Claim
Creatine supplementation combined with resistance training has no significant effect on upper limb strength in healthy adults aged 50 and older when the intervention lasts 52 weeks or longer, but is associated with a moderate improvement in upper limb strength (SMD = 0.45) when the intervention lasts 32 weeks or less.
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 healthy adults aged 50 and older, taking creatine with resistance training for 32 weeks or less is associated with a moderate increase in upper limb strength, but no significant change occurs when the training lasts 52 weeks or longer.
See the scientific wording
Creatine supplementation combined with resistance training does not significantly improve upper limb strength in healthy adults aged 50 and older over interventions lasting 52 weeks or longer, but may produce a moderate improvement (SMD = 0.45) in those receiving treatment for 32 weeks or less.
Taking creatine helps muscle cells store more energy, which lets them work harder and longer during strength training. This allows older adults to lift heavier or do more reps, which stresses the muscles enough to grow stronger. After about 8 months, the muscles stop responding to this extra stress, so strength no longer improves.
What the research says
1 studyTaking creatine with strength training doesn’t make older adults’ arms stronger if they do it for more than 8 months, but it does help a little if they only do it for 8 months or less.
