Does Caffeine Have Any Effect On Resistance Exercise?

Posted on Updated on

Many gym-goers are looking for ways to get more work in during their training sessions. Some turn to pre-workout supplements while others may turn to steroid-related drugs. Although pre-workout supplements contain caffeine, it’s also filled with unnecessary and potentially dangerous substances.

Caffeine on resistance training has been long looked at with supportive research data on its effect. Caffeine’s major effect for training is that it reduces pain perception, potentially delaying fatigue during exercise.  Additionally, caffeine may also reduce RPE (rate of perceived exertion) which may extend duration and/or intensity of workouts.

Sources could come as either coffee or caffeine powder/pills. The most important information to know is that 3-6mg/kg may be the optimal range to see effects or a dose of approximately 200mg 1 hour before exercise. 2-3 cups of coffee may be the optimal dose; however, caffeine content depends on the type of coffee and if any espresso shots are added. Experiment with doses and types and find the right amount to see individualized results.
