contractile protein filament‚ with protusions known as Myosin Heads. Tropomyosin: An actin-binding protein which regulates muscle contraction. Troponin: A complex of three proteins‚ attached to Tropomyosin. Stage 1 Nervous impulse arrives at neuro-muscular junction – acetylcholine is released. This causes calcium to be released from the sarcoplasmic reticulum. The calcium binds to troponin‚ changing its shape and so moving tropomyosin. This exposes the active binding site of the Actin. The Myosin

90% of the one repetition maximum for 2–6 repetitions (reps) causes myofibrillated hypertrophy to dominate (as in powerlifters‚ olympic lifters and strength athletes)‚ while several repetitions (generally 8 – 12 for bodybuilding or 12 or more for muscular endurance) against a sub-maximal load facilitates mainly sarcoplasmic hypertrophy (professional bodybuilders and endurance athletes).[citation needed] The first measurable effect is an increase in the neural drive stimulating muscle contraction.
