GCSE Physical Education: Exercise and Fitness as part of your Healthy, Active Lifestyle KEYWORDS ❖ Health: a state of complete mental, physical and social well-being and not just the absence of disease and infirmity ❖ Exercise: a form of physical activity which maintains or improves health and/or physical fitness ❖ Fitness: the ability to meet demands of the environment ❖ Performance: how well a task is completed 5 COMPONENTS OF HEALTH-RELATED EXERCISE Cardiovascular Fitness ❖ The ability to exercise the entire body for long periods of time ❖ It describes the efficiency of the heart, lungs and blood vessels (cardiovascular system) to deliver oxygen to working muscles efficiently. E.g. marathon / triathlon Muscular Strength
❖ The amount of force a muscle can exert against a resistance ❖ It can be developed by lifting heavy weights with few repetitions at a high intensity. E.g. weightlifting Muscular Endurance ❖ The ability to use the voluntary muscles many times without getting tired ❖ It enables muscles to be exercised and used repeatedly without getting tired. E.g. tennis / swimming Flexibility ❖ The range of movement possible at a joint ❖ E.g. gymnastics / dance Body Composition ❖ The percentage of body weight that is; fat, muscle and bone ❖ Is influenced by genetics, and can be altered by exercise and diet. E.g. sumo wrestler v.s. marathon runner 6 COMPONENTS OF SKILL-RELATED EXERCISE
note: can be memorized by algorithm [ABC PRS] Agility ❖ The ability to change the position of body quickly and to control the movement of the whole body ❖ E.g. dodging defenders or tackling in football Balance ❖ The ability to retain the centre of mass (gravity) above the base of support. With reference to static (stationary) or dynamic (changing) conditions of movement, shape and orientation ❖ E.g. gymnastics pose (static) / hammer throw (dynamic) Coordination ❖ The ability to use two or more body parts together ❖ E.g. basketball (hand-eye) / football (foot-eye) Power ❖ The ability to undertake strength performances quickly. Power = strength x speed
❖ E.g. long jump / swimming Reaction time ❖ The time between the presentation of a stimulus (e.g. starting pistol sound) and the onset of movement ❖ E.g sprinting / goalkeeping Speed ❖ The differential rate at which an individual is able to perform a movement or cover a distance in a period of time ❖ E.g. sprinting / boxing
