Summary

This study looks at whether a single dose of caffeine (3 mg per kg of body weight) can improve muscle strength and endurance in healthy older adults aged 55 and older who have not done resistance training before. Participants will perform exercises like bench press and back squat, and researchers will measure movement speed, number of repetitions, and grip strength. The goal is to understand how caffeine affects exercise performance in older adults and whether genetics or sex play a role.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: caffeine (3 mg/kg)
What this could lead to: If it works, this could help older adults use caffeine strategically to boost exercise performance and maintain physical function.
What could go wrong: This is a small, early-stage study in healthy volunteers, so results may not apply to less active or older populations. Caffeine can cause side effects like jitters or sleep disruption.
