Health – related * Aerobic capacity * Muscular strength * Muscular endurance * Flexibility * Body compisistion
Sport/skill related * Muscular power * Agility * Speed * Balance * Coordination
Aerobic capacity * Also called stamina, general endurance, heart-lung fitness * “The ability to keep producing energy aerobically and using it to perform tasks involving the whole body for extended periods of time” * The body needs constant oxygen delivered to the muscles as well as removing waste. * Eg: team sports, cycling etc.
Muscular strength * “The force that a muscle or group of muscles can exert against a resistance
in a single maximal contraction”. * In reality it is used to perform an action that requires large amounts of force up to a maximum of 10 consecutive times. * Eg: jumping
Muscular endurance * “The ability to work a muscle for long periods at less than maximum effort, where local fatigue rather than general exhaustion is the limiting factor”. * High ratio of res (slow-titch) fibres. * Eg: jogging
Flexibility * “The ability of the muscles, ligaments and tendons to allow large movements of the joints”. * Often called mobility or suppleness, * Can be increased through stretching. * Eg: gymnastics, dancing, hurdling.
Body composition * “The ratio of fat to non-fat components in your body”. * Non-fat = lean body mass * Fat can be essential (in and around organs) or storage (in cells around the body). * Most commonly measured by the skin folds.
Muscular power * “ability to use strength quickly to produce an explosive effort”. * Power = trade off between speed and strgnth * High ratio of white (fast-twitch) fibres needed. * Eg: sprint starts
Agility
* “The ability to change the position of the body quickly and precisely and still retains balance”. * To be agile, you must be able to accelerate quickly, turn, dodge and weave. * It relies on anaerobic energy for speed as well as muscular power and flexibility
Speed
* “The ability to put body parts into motion quickly and to sustain high intensity efforts, for which anaerobic energy is required”.
Balance
* “The ability to maintain the body in equilibrium while stationary (static) or moving (dynamic).
Coordination
* “The ability of your body’s senses (especially sight and hearing), your nervous system and your muscles to work together so that you can perform specific movements smoothly and accurately”. * The more complex the task the greater the coordination needed.
