Increase in concentration of calcium ion will result increase number of power stroke and force for contraction.  However latent period and relaxation period are unaffected by caffeine. Increase in concentration of calcium ion will result increase number of power stroke and force for contraction.

Because of calcium ion release in skeletal muscle, caffeine causes peripheral manifestation such as hyper-reflexia, muscle twitching etc.

High amount of caffeine leads to increase in release of Ca2+ from sarcoplasmic reticulum. It increases tension development in single tetanic contraction and re-initiate maximum tension in fatigue single myofibre by restoring Ca2+ release from sarcoplasmic reticulum to non-fatigued levels.
