fitness components (SAC 4) Flashcards
(53 cards)
Aerobic power: Definition
- The fitness of the heart, blood vessels and lungs to deliver energy for the maximum time an individual can sustain aerobic effort
- Depends on the supply of O2 to the working muscles
Aerobic power: Factors affecting
- gender
(males generally have a higher VO2 max due to greater size of organs, blood volume and muscle mass) - fibre type
(a greater percentage of slow-twitch fibres will increase VO2 max)
Aerobic power: Sporting examples
- long distance, walking, running, cycling and swimming
- most ball sports
Aerobic power: Fitness tests
- beep test (20m shuttle run)
- (20m between each end, speaker to play the soundtrack, players line up on the line and run to the beeps)
- YoYo intermittent recovery test
Body composition: Definition
- The percentage of fat, bone and muscle in the body
- (measures lean body mass to body fat content)
Body composition: Factors affecting
- genetics
(genetic predisposition to have similar body composition to parents) - diet and physical activity levels
(energy output should be greater than energy input to avoid increases in body fat)
Body composition: Sporting examples
- tall (basketball)
- small (jockey)
- heavy (sumo)
- light (gymnastics)
Body composition: Fitness tests
- body mass index (BMI)
(insert the data into the BMI) - waist circumference
Flexibility: Definition
- The body’s ability to achieve the range of movement that is demanded by a particular sport or activity
Flexibility: Factors affecting
- joint structure
(type of joint can determine the number of directions movement is allowed) - somatotypes
(endomorphs (fat mass) and mesomorph (muscle mass) have limited range of movement due to the increased tissue
Flexibility: Sporting examples
- yoga
- gymnastics
- diving
- dance
- hockey goalkeeper
Flexibility: Fitness tests
- modified sit and reach
(legs fully extended agaisnt the sit and reach box, hands on top of eachother reach as after as you can) - shoulder and wrist elevation
Muscular endurance: Definition
- The ability of a single muscular group to continue physical output and delay the onset of fatigue
Muscular endurance: Factors affecting
- fatigue
(increased ability to resist fatigue due to an increased lactate tolerance) - fibre type
(the greater the percentage of slow-twitch fibres within the muscles, the greater the resistance to fatigue)
Muscular endurance: Sporting examples
- arms and legs in 200m swim
- legs in 1km time trial
Muscular endurance: Fitness tests
- timed sit-ups
- timed push-ups
Muscular strength: Definition
- The maximal force that can be exerted by a muscle or a muscle group in one effort
Muscular strength: Factors affecting
- speed of contraction
(the slower the speed of contraction, the more force produced) - cross-sectional area of muscle
(the larger the cross-sectional area of the muscle, the greater the force produced)
Muscular strength: Sporting examples
- forward pushing in a rugby scrum
- holding a baseball bat during a full swing
Muscular strength: Fitness tests
- hand grip dynamometer test
- 1RM bench press
Agility: Definition
- Combines speed with flexibility and dynamic balance, allowing the performer to change direction with maximal speed and control
Agility: Factors affecting
- centre of gravity
(a lower centre of gravity will provide greater balance and therefore enhance agility) - flexibility
(greater flexibility results in greater speed and therefore increases agility
Agility: Sporting examples
- basketball (dribbling and defending players)
- moving to hit a ball in tennis
- rugby (side stepping)
Agility: Fitness tests
- illinois agility test
(cones mark the start and end, and four cones are placed down the middle 3.3m apart, time how long it takes the athlete to run through) - semo agility test
