front 1 Adaptation | back 1 the evolutionary process whereby an organism becomes better able to live in its habitat or habitats. |
front 2 Aerobic exercise | back 2 any physical activity that uses your body's large muscle groups in a rhythmic and repetitive manner, increasing your heart rate and how much oxygen your body uses. |
front 3 Anaerobic exercise | back 3 intense, short-burst activity that uses stored energy in muscles, rather than oxygen, to fuel movement. |
front 4 Cardiovascular endurance | back 4 the ability of your heart, lungs, and circulatory system to efficiently deliver oxygen to your muscles during physical activity. |
front 5 Concentric exercise | back 5 involve muscle shortening while a muscle contracts against a resistance. |
front 6 Cool down | back 6 the period of reduced intensity activity after exercise, allowing your body to gradually return to a resting state. |
front 7 Diminishing return | back 7 a phenomenon where, after a certain point, adding more of a specific input leads to a smaller and smaller increase in output. |
front 8 Eccentric exercise | back 8 involve a muscle lengthening while it's contracted, typically during the downward or lowering phase of a movement. |
front 9 Exercise plateau | back 9 occurs when your body adapts to your current exercise routine and you no longer see progress, even with consistent effort. |
front 10 F.I.T.T. principle | back 10 a set of guidelines used to design effective fitness programs. |
front 11 Flexibility | back 11 the quality of bending easily without breaking. |
front 12 Heart rate | back 12 between 60 and 100 beats per minute (bpm). |
front 13 Muscular contraction | back 13 a fundamental physiological process where muscle fibers generate tension and can shorten, causing movement. |
front 14 Muscular endurance | back 14 the ability of a muscle or group of muscles to repeatedly exert force against a resistance, like body weight or weights, over a period of time. |
front 15 Muscular strength | back 15 the ability of a muscle to exert a maximal or near maximal force, often measured by how much weight you can lift or push. |
front 16 Overload principle | back 16 working the body harder than it's accustomed to in order to make gains in strength, endurance, and muscle size. |
front 17 Plyometrics | back 17 exercises that involve rapid and explosive movements to increase muscle power, speed, and agility. |
front 18 Range of motion | back 18 the extent of movement possible at a joint. |
front 19 Repetitions | back 19 the action of repeating something that has already been said or written. |
front 20 Warm-up | back 20 a preparatory activity that prepares the body for physical exertion by increasing heart rate, blood flow, and muscle temperature, reducing the risk of injury. |
