Describe the two ways that the law of acceleration can be used to alter aquatic exercise - ANSWER-Pushing harder against the pool bottom to propel the body upward or through the water and pushing harder against the water's resistance with the arms and legs What i the maximum force that can be exerted by a muscle or muscle group against a resistance - ANSWER-muscular strength What is the sliding filament theory? - ANSWER-Bands of actin & myosin do NOT change length to cause the muscle to contract, rather they slide over each other. What is tempo? - ANSWER-Cadence or speed of movement What is impact? - ANSWER-Depends on body position and movement technique. All options can be performed at various intensities What are the 3 aquatic tempos used? - ANSWER-Land, water, 1/2 water What are the impact options for aquatics? - ANSWER-Levels 1,2,3 combined levels Grounded/ anchored Propelled, elevated water specific How do you alter aquatic intensity? - ANSWER-inertia acceleration action & reaction frontal resistance levers What type of stretching activates the muscle spindles, specialized receptors in the muscle that monitor muscle length change and the speed of muscle length change? - ANSWER-ballistic stretching What are the six skill-related components of fitness - ANSWER-balance, coordination, speed, power, agility, and reaction time What is maximal heart rate? - ANSWER-highest heart rate a person can achieve. measured with a max HR test or estimated with 220- age. What is heart rate reserve? - ANSWER-your maximal HR minus your resting heart rate. ow is your HR lowered through compression in the water? - ANSWER-water compresses all the body systems, including the vascular system, causing a smaller venous load to the heart, reducing heart rate. What is the recommended frequency for resistance training? - ANSWER-two to three days/week for each major muscle group What is body composition? - ANSWER-the body's relative percentage of fat as compared to lean tissue (bones, muscles, and organs) What are five benefits of regular exercise? - ANSWER-improves physical appearance increases functional capacity heart becomes stronger strengthens the walls of the blood vessels improves strength and endurance When calculating exercise intensity, a popular method is the Karvonen Formula, which is also known as the ____ - ANSWER-Heart Rate Reserve method ____ is a subjective method of assessing effort, strain, discomfort, and fatigue experienced during exercise. - ANSWER-rating of perceived exertion The skeletal system provides our bodies with support, protection, and _____. - ANSWER-Structure During the cardiac cycle, ____ is the active contraction of the heart muscle and ___ is the relaxation of the heart muscle. - ANSWER-Systole, Diastole Which characteristic of muscle allows it to shorten and thicken? - ANSWER-Contractility What muscle group flexes the leg at the knee? - ANSWER-Hamstrings What is a motor neuron? - ANSWER-Efferent neurons that relay outgoing information from the central nervous system to the muscle cells How is the valsalva maneuver done? - ANSWER-Holding one's breath while exerting. Creates unequal pressure in the chest, causing blood pressure to drop and decreasing blood flow to the heart. Resuming normal breathing creates a surge of blood flow to the heart, causing a sharp increase in blood pressure. What is the result of the Valsalva Maneuver? - ANSWER-Creates unequal pressure in the chest, causing blood pressure to drop and decreasing blood flow to the heart. Resuming normal breathing creates a surge of blood flow to the heart, causing a sharp increase in blood pressure.
