Taking 6 milligrams of caffeine per kilogram of body weight before jumping can slightly increase how high a young man who rarely consumes caffeine can jump, compared to when he takes a placebo.

Are Caffeine’s Effects on Resistance Exercise and Jumping Performance Moderated by Training Status?

Randomized Controlled Trial

Human

2022 Nov 16

This study found that taking a caffeine pill (6 mg per kg of body weight) made young men jump a little higher—about 3.8 to 3.9 cm—compared to when they didn’t take it. The effect was small but real and consistent, just like the claim says.

Similar Assertions

Taking a dose of 6 mg of caffeine per kilogram of body weight has almost no meaningful impact on how much weight a young man who rarely consumes caffeine can lift in a single repetition of bench press or squat, even if the change is statistically detectable.

In young males, whether someone is regularly strength-trained or just casually active does not change how much acute caffeine improves muscular endurance, jump height, or one-rep max strength.

Taking 6 milligrams of caffeine per kilogram of body weight before a workout can increase the number of repetitions a person can perform to failure during bench press and squat exercises at 70% of their maximum strength, based on measured effect sizes in young men who rarely consume caffeine.
