HEALTH-RELATED components of fitness:Directly associated with good health. • Body composition: prevention of obesity, high blood pressure, diabetes etc. • Flexibility: prevention of back pain and muscle injuries. • Strength: prevent back and posture problems. • Muscle endurance: promote daily living functionality. • Cardiovascular endurance: prevention of heart disease. Moderate amount of each component of health-related fitness has a direct relationship to good health and reduced risk for disease.
SKILL-RELATED components of fitness – More associated with performance than with good health. People who possess these skills find it easy to achieve high levels of performance in motor skills, such as those required in sports.
Power Agility SKILL-RELATED components of fitness Reaction Time Balance Speed Co-ordination
SKILL-RELATED components of fitness • Agility: The ability to rapidly and accurately change the direction of the movement of the entire body in space. Example: dribbling a soccer ball with your feet, dribbling a hockey ball with a hockey stick, quickly changing direction on a netball court etc.
SKILL-RELATED components of fitness Balance: The maintenance of equilibrium while stationary or while moving. Example: gymnast on a balance beam, water skiing, jumpers in a rugby lineout etc.
SKILL-RELATED components of fitness Reaction Time:The time elapsed between stimulation and the beginning of the reaction to that stimulation. • Quicker = better. • Slow = poor reaction time skills • Example: starting a sprint race, catching a ball etc.
SKILL-RELATED components of fitness Speed:The ability to perform a movement in a short period of time. Or, the rate at which the body or individual limbs can move. Example: 40m sprint, soccer playing sprinting to receive the ball etc.
SKILL-RELATED components of fitness • Co-ordination:The ability to use the senses with the body parts to perform motor tasks smoothly and accurately. • Hand-eye co-ordination: juggling, tennis, volleyball etc. • Foot-eye co-ordination: soccer, football etc.
SKILL-RELATED components of fitness • Power:is the production of strength at speed and can be seen when we throw an object or perform a sprint start. • Example: throwing a discus, shot-put, jumping is basketball etc.
HEALTH-RELATED components of fitness • Body Composition: The relative percentage of muscle, fat, bone, and other tissues that comprise the body. • Athlete = relatively low body fat percentage. • High body fat = poor performance.
HEALTH-RELATED components of fitness • Flexibility: Is the range of motion that a joint or group of joints can move through. It is affected by muscle length and joint structure. • Good flexibility = reduced risk of injury. • Poor flexibility = greater risk for injury.
HEALTH-RELATED components of fitness • Cardiovascular Fitness:It is the individuals ability to take on, transport and utilize oxygen. It is a measure of how well the lungs can take in oxygen, how well the heart and blood can transport oxygen, and then how well the muscles can use oxygen. • A fit person can sustain long periods of exercise without fatigue. • Fit athlete = good performance. • Unfit athlete = poor performance.
HEALTH-RELATED components of fitness Muscular Endurance: Is how well the muscles can produce repeated contractions at less than maximal (sub-maximal) intensities. A fit person can repeat movements for a long period of time without fatigue.
HEALTH-RELATED components of fitness Strength: Is the maximum force a muscle or group of muscles can produce in a single contraction. Greater strength = greater power. = reduced risk for injury.
