Glycolysis-lactic acid (anaerobic) system
No oxygen required in muscles for short amount of time, breaks down glucose to substitute oxygen
Fast glycolytic muscle fibers
Fastest muscle type in humans, contracts with great force, but can only sustain short anaerobic bursts
Relaxation time between twitches gets shorter while the strength of contraction amplifies
Fine sheath of connective tissue composed of teticular fibers surrounding each muscle fiber
Sliding filament mechanism
Thin filaments slide past thick ones, myosin binds and detaches several times during contraction
