Are regulated by electrical signals from motor nerves, which originate in the spinal cord and send messages to individual muscles throughout the body. Muscle actions true Isotonic false Muscular strength false Single Movements result from moving a constant load. Muscular power false Isotonic true Muscular strength false Single The maximum amount of load a muscle can work against in a single bout of maximum effort. Muscular power false Skeletal muscle false Muscular strength true Single The ability to recruit a large number of muscle motor units quickly to move a load. Muscular power true Skeletal muscle false Slow-twitch muscle fibers false Single A collection of long, thin cells called fibers. motor unit false Skeletal muscle true Slow-twitch muscle fibers false Single Muscle fibers that are relatively fatigue resistant but they don’t contract as rapidly or strongly as fast-twitch fibers. motor unit false Resistance training false Slow-twitch muscle fibers true Single A nerve and all the muscle fibers it innervates motor unit true Resistance training false Specificity false Single Also known as strength or weight training FITT principles false Resistance training true Specificity false Single States that to develop muscular strength, exercises that improve strength must be performed. FITT principles false Muscle actions false Specificity true Single May guide you in the creation of your strength training program. FITT principles true Muscle actions false Isotonic false Single
