Caffeine: The Science Behind Why It May Increase Power & Strength

Caffeine may enhance strength/power by altering the release or uptake of calcium by the sarcoplasmic reticulum. The regulation of calcium controls muscular contractions, more specifically causing myosin to form a strong bond with actin filaments. Theoretically, if calcium release is increased from the sarcoplasmic reticulum, this could lead to longer and stronger muscle contractions = MORE STRENGTH

  1. Fyi by the time caffeine effects the amount of calcium released from the sarcoplasmic reticulum in the skeletal muscle it is likely that you would’ve died. 200-300 mg off caffeine found preworkouts would only amount to 200-300 micromolar concentrations of caffeine in the circulation. Which according to the literature (follow Graham Lamb/George Stephenson) will not have any significant effect on the amount of calcium release.
