Semester One Exam Flashcards
Fit Body Characteristics
Higher work output Effect heart and lungs Additional energy reserves Lower body fat Good muscle fat Lower resting heart rate Decreased stress on body during physical activity Faster recovery time
Fitness
The capability of the heart blood vessel, lungs and muscles to function at optimal efficiency. Fitness aims to restore and support the normal physiological functioning of the body. Fitness is last through inactivity and age
Health Related Components of Fitness
Cardio Respiratory Endurance Muscular Strength Muscular Endurance Flexibility Body Composition
Cardio Respiratory Endurance
The capacity of the body to be involved in continuous physical activity for an extended period of time. Tests to determine this are, VO2 Max Test, Harvard Step Test and Beep Test
Muscular Strength
Muscular strength is the ability of a muscle or a group of muscles to exert a force against a resistance in a singular muscular function Eg. grip test
Muscular Endurance
Is the ability of a muscle or a muscle group to exert force repeatedly over an extended period of time or sustain a contract for an extended period of time. Sit ups, flexed arm hangs and push ups are examples of tests for it
Flexibility
Capacity of a joint to move full range or bend, stretch and twist without injury eg sit and reach
Body Composition
Indicates the percentage of fat, muscle and bone that make up body weight. Tests; skin measurements, specific gravity method and body mass index
Performance Related Components of Fitness
Power Speed Agility Reaction Time Co-ordination Balance
Power
Muscle power is the ability to real release maximum force quickly. Combination of strength and speed to produce an explosive action. Test; standing long jump and standing vertical jump
Speed
Ability to perform a movement or cover a distance in a short period of time. Tests: sprints
Agility
Change the position of the body quickly and efficiently whilst retaining balance; Illinois Agility Run
Reaction Time
Time between receiving a signal to move and the actual physical response; ruler dropping test
Co-ordination
Ability of the boy sense, nervous systems and muscles to perform specific movements smoothly and accurately; juggling
Balance
Maintaining the body equilibrium whilst stationary or in motion; beam balance
Improving Fitness
Differences in abilities may differ because of genetic limitation and influences from previous experiences
Training
Warm Up
Conditioning Phase
Cool Down
Warm Up
Reduces risk of muscle injury and soreness
Increases blood flow
Increases body temperature
Lubricates muscles and joints
Decreases muscle tension
Stimulates heart and lungs moderately
Alerts nervous system to fit physical and mental demands
Conditioning Phase
Intensity to reach 70-85% of maximum heart rate
Intensity and duration caries on fitness level
Cool Down
Slowly bringing intensity down until 100bpm
Followed by stretching to reduce risk of injury and soreness
Effective cool downs decrease body temperature and heart rate
Classification of Motor Skills
Classified according to particular characteristics and factors that need to be taken into account in individuals performance
