The component model of fitness Flashcards
(27 cards)
What are skill-related fitness components?
Skill-related fitness components improve a persons physical performance in motor skills.
Referred to as athletic ability or performance components.
Includes muscular power, speed, agility, coordination, balance, and reaction time
What are health-related fitness components?
Health-related fitness components have been identified as those that are more important to health than to athletic or sporting ability.
These are aerobic capacity, anaerobic capacity, muscular strength, flexibility and body composition.
What is aerobic capacity?
The ability of the cardiovascular and respiratory systems to take up and supply oxygen to the muscles to sustain exercise.
What are factors affecting the “aerobic capacity” component?
VO2 Max: should be high.
Lactate inflection point: should occur late.
Gender: males have ⬆️ power, females have ⬇️ power
Age: peaks 25-28
Heredity: 90-95%
Training: Slow twitch muscle fibre characteristics.
What is anaerobic capacity?
The ability of the body to produce energy without using oxygen and hence the efficiency/power of the two anaerobic energy systems~ the
ATP-PC and anaerobic glycolysis systems.
What are the factors affecting. Anaerobic capacity?
Age: peaks around 30 Gender: males more than females Lactic acid and metabolite tolerance. Fibre type: Fibre recruitment:
What is muscular strength?
The maximal force that can be generated by a muscle or muscle group in one maximal effort.
What can effect muscle strength?
Muscle group Type of contraction Speed of contraction Joint angle Size of muscle Shape and fibre composition Age Gender
What is an isometric contraction?
When muscle length remains constant as force is developed.
What is concentric contraction?
When muscle shortens as force is developed.
What is eccentric contraction?
When muscle lengthens as force is developed.
What is muscular endurance?
The ability of the muscle or muscle group to perform repeated contractions (concentric, eccentric, or isokinetic) for an extended period of time, or to maintain a contraction for an extended period of time (isometric contraction).
What factors affect muscular endurance?
Fatigue Fibre type Age Gender Blood flow Training Lactic acid and metabolite tolerance Muscle temperature
What is flexibility?
The ability of a joint to move through it’s full range motion.
What factors are affecting flexibility?
Joint structure Age Gender Resistance Somatotype Temperature Training
What is static flexibility?
The ability to reach and hold a point in a joints range of motion.
What Is dynamic flexibility?
The ability to move a joint quickly through it’s range of motions with little resistance.
What is body composition?
The ratio of fat-free mass to fat-mass and essentially a persons body shape, or somatotype.
What are the factors affecting body composition?
Age Gender Fibre type Genetics Energy balance Hormone imbalances
What is reaction time?
The time in between a signal being detected and the first movement/response to this signal.
What are factors affecting reaction time?
Optimal arousal and concentration
Number of responses
Noise
What is agility?
Agility is the ability to change body position or direction quickly and accurately whilst maintaining balance.
What are factors affecting agility?
Centre of gravity Speed Reaction time Range of motion at joints Fibre type Flexibility
What is coordination?
The ability to use the body’s senses to execute motor skills smoothly and accurately
