| Term | Definition |
|---|---|
| physical fitness | The body’s ability to respond or adapt to the demands and stress of physical effort. |
| health related fitness | Physical capabilities that contribute to health, including cardiorespiratory endurance, muscular strength, muscular endurance, flexibility, and body composition. |
| cardio respiratory endurance | The ability of the body to perform prolonged, large-muscle, dynamic exercise at moderate to high levels of intensity. |
| cardio respiratory endurance training | Exercise intended to improve cardiorespiratory endurance. |
| muscular strength | The amount of force a muscle can produce with a single maximum effort |
| musuclar endurance | The ability of a muscle or group of muscles to remain contracted or to contract repeatedly for a long period of time. |
| flexibility | The joints’ ability to move through their full range of motion. |
| body composition | The proportion of fat and fat-free mass (muscle, bone, and water) in the body. |
| fat free mass | The nonfat component of the human body, consisting of skeletal muscle, bone, and water. |
| skill related fitness | Physical abilities that contribute to performance in a sport or activity, including speed, power, agility, balance, coordination, and reaction time. |
| physical activity | Any body movement carried out by the skeletal muscles that requires energy. |
| electrocardiogram EKG | A recording of the changes in electrical activity of the heart |
| specificity | The training principle that the body adapts to the particular type and amount of stress placed on it. |
| progressive overload | The training principle that placing increasing amounts of stress (in the form of exercise) on the body causes adaptations that improve fitness. |
| reversibility | The training principle that fitness improvements are lost when demands on the body are lowered. |
| maximal oxygen consumption | The body’s maximum ability to transport and use oxygen. |
| target heart range | The range of heart rates that should be reached and maintained during cardiorespiratory endurance exercise to obtain benefits |
| resistance exercise | Exercise that forces muscles to contract against increased resistance; also called strength training. |
| isometric exercise | The application of force without movement. |
| isotonic exercise | The application of force with movement. |
| anabolic steroids | Synthetic male hormones used to increase muscle size and strength |
| cross training | Participating in two or more activities to develop a particular component of fitness. |
