40 yd dash: muscle endurance the (cid:373)us(cid:272)le"s a(cid:271)ility to (cid:373)ai(cid:374)tai(cid:374) a for(cid:272)e over time, reps to exhaustion, general principles of training. Individuality everyone is different: specificity training must be sport specific, reversibility use it or lose it, progressive overload increase intensity to continue gaining, variation periodization, types of exercises. Isotonic (dynamic: constant load, concentric vs. eccentric. Isokinetic: constant speed, resistance to ensure constant motion speed, phases of strength gain, neural adaptation learning the motion, synchronization of motor unit recruitment, decreased inhibitory signals from the golgi tendon orgna, decreased antagonist co-activation. Increased motor neuron firing frequency: muscle hypertrophy, transient hypertrophy due to fluid accumulation during contraction. Get swole: chronic hypertrophy structural increase in size. Gainz: fiber hypertrophy primary cause of chronic hypertrophy. Increased protein synthesis: greater no. of larger myofibrils. Increase in sarcomere no: satellite cell proliferation, growth, maintenance and repair.
