Unformatted text preview: Integrated Strength Training Define strength training and why its important Strength is the ability of the neuromuscular system to provide internal tension and exert force against external resistance Aerobic exercise improves cardiorespiratory fitness, but does little to improve muscular strength Review anatomical and physiological aspects of improving strength Neuromuscular system Nerves connect with muscles, and depending on the stimulus, tells the muscles to contract (development of internal tension) The higher the stimulus (weight), the more muscle fibers contract The more fivers that contract, the more resistance we can overcome (strength) Musculoskeletal system Bones, muscles, and tendons create a series of levers and pulleys that generate force against external objects Particular attachments of muscles to bones will determine how much force the muscle is capable of generating o Biomechanics Types of muscle contractions Concentric o Muscle shortening occurs while tension is developed to overcome a resistance Eccentric: o Muscle contraction that involves a lengthening of the muscle Isometric: o Muscle contraction that produces tension but does not result in a change of muscle length o Considerable force can be generated without movement occurring...
