Summary: A 2026 randomized, double-blind crossover trial in the Journal of the International Society of Sports Nutrition tested caffeine gum doses of 3 mg/kg and 6 mg/kg before a heavy squat priming session in 15 male basketball players. Both caffeine conditions improved same-day barbell velocity and later testing on isometric strength, jump performance, sprinting, and reactive agility versus placebo, but the extra edge did not persist 24 or 48 hours later.
Why it matters for lifters
- This looks like a same-session tool, not a recovery hack: The main benefit showed up on the day of the session, which matters if you care about warm-up quality, bar speed, and getting more pop out of a performance-focused workout.
- More is not automatically better: The 6 mg/kg dose did not clearly beat 3 mg/kg, which is useful for lifters who want performance upside without pushing caffeine dose higher than needed.
- Context still matters: The study was done in male basketball players inside a resistance-priming setup, so bodybuilders and general gym lifters should treat this as targeted evidence rather than a universal pre-workout rule.
What to watch next
- Watch for replications in resistance-trained lifters, not just court-sport athletes.
- Watch whether future trials compare caffeine gum directly with standard caffeine drinks or capsules under matched training conditions.
- If you use caffeine before training, track tolerance, sleep, and total daily intake instead of assuming a study result guarantees a net win for you.
