FITNESS : FITNESS Aerobic and Anaerobic Exercise Physical Fitness : Physical Fitness Physical fitness is the result of regular exercise, proper diet and nutrition, and proper rest for physical recovery. Physical Fitness Components : Physical Fitness Components Accuracy Agility Balance Body Composition Cardiovascular Endurance Coordination Flexibility and Joint Range of motion Strength Speed Power Stamina Accuracy : Accuracy In relationship to physical fitness, accuracy is: The ability to hit a target. Ability of a performer to repeat movements successfully. The ability to perform without making any errors. Agility : Agility Agility is the ability to change one’s body position. Requires a combination of balance, coordination, speed, reflexes, and strength. In sports, agility is explained in terms of a response to an opponent or moving target. Balance : Balance Balance is the ability to maintain a stable position while stationary (static balance) or moving (dynamic balance). Balance is achieved by the action of reflexes involving the eyes, the balance organs of the semi-circular ear canal, pressure receptors in the skin, and stretch receptors in the joints and muscles. Good balance is needed in sports, especially those requiring sudden movements or change of direction. Body Composition : Body Composition Is used to determine the % of fat, bone, and muscle in our body. Because muscle tissue takes up less space that fat tissue, our body composition, as well as our weight, determines how lean we are. Body composition can be measured many ways, the most common being with a set of measurement calipers to deteremine Body Fat Percentage. Cardiovascular Endurance : Cardiovascular Endurance The ability to sustain a large blood flow to active muscles. Aerobic Exercises build Cardiovascular Endurance. Cardio Respiratory Endurance is vital to “whole body” activities. Coordination : Coordination Gross Motor Coordination: Walking, running, climbing, jumping, etc… Fine Motor Coordination: Small muscle movements, like the fingers in coordination with the eyes. Flexibility : Flexibility The measurement of achievable distance between the flexed and extended position of a particular joint or muscle group is “flexibility”. Also known as range of motion at a joint. Strength : Strength Physical strength is the ability of a person to exert force on physical objects using muscles. An individual’s physical strength is determined by their genetic inheritance of muscle fibers, and their degree of strength training they undertake. Power : Power The rate at which energy is expended or work is done. The amount of power generated by a person depends on two factors: Speed and Strength. Power is a key component for most athletic activities. A powerful athlete has to transform physical energy into force at a fast rate. Speed : Speed The ability to execute movements quickly. Speed refers to distance traveled per unit of time (i.e. secs). In running and walking, speed is a product of stride rate. Speed of movement either the total body or a particular body part is an important component of performance related fitness. Stamina (Endurance) : Stamina (Endurance) The ability to sustain a specific activity for a long period of time. Muscular Endurance is vital to activities specific to individual muscles (weight lifting).
