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
