Unformatted text preview: 11-22-08Integrated Strength TrainingDefine strength training and why its importantReview anatomical and physiological aspects of improving strengthReview the benefits of strength trainingReview important strength training principlesDescribe different strength training tools and aidsReview progressions and guidelines for strength trainingWhat is Strength?The ability of the neuromuscular system to provide internal tension (muscle contraction) and exert force against external resistance (weight).Why is Strength Training important?Aerobic exercise improves cardio-respiratory fitness, but does little to improve muscular strengthoImportant for athletic performance and doing the normal activities of daily livingSystems Involved in Strength DevelopmentNeuromuscular systemoNerves connect with muscles and depending on the stimulus, tell the muscles to contract (development of internal tension)oThe higher the stimulus (weight), the more muscle fibers are told to contractoThe more fibers that contract, the more resistance we can overcome (strength)Musculoskeletal systemoBones, muscles, and tendons create a series of levers and pulleys that generate force against external objectsoParticular attachments of muscles to bones will determine how much force the muscle is capable of generatingBiomechanicsTypes of Muscle Contractions that Need to e TrainedConcentric contractionoMuscle shortening occurs while tension is developed to overcome a resistanceEccentric contractionoMuscle contraction that involves a lengthening of the muscleIsometric contractionsoMuscle contraction that produces tension but does not result in a change of muscle lengthoConsiderable force can be generated without movement occurring....
