fitness components and assessment of fitness Flashcards
health related fitness components
aerobic power body composition flexibility muscular endurance muscular strength
skill-related fitness components
agility anaerobic capacity balance coordination muscular power reaction time speed
aerobic power
rate of energy released from aerobic respiration
relies on available oxygen
predominant energy system supplier for team/long distance
factors affecting aerobic power
gender
fibre type- slow
blood volume
muscular endurance
ability to continue repeated muscle movement for extended period
factors affecting muscular endurance
fatigue resist
slow twitch fibres
gender
flexibility
interaction between skeletal and muscular systems to allow full range of joint movement
static- range of motion possible when not moving
dynamic- resistance to motion in a joint when moving
factors affecting flexibility
age
muscle temp
joint structure
body composition
proportion of bone, muscle and fat within the body
lean tissue= muscle, bones and organs
fat tissue= essential and non essential fats
factors affecting body composition
gender
genetics
diet
anaerobic capacity
total yield of energy that can be obtained by atp-pc and anaerobic glycolysis
factors affecting anaerobic capacity
gender
fast twitch fibres
genetic make up
muscular strength
contracting muscles develop tension while shortening or staying the same lenght
types of muscular strength
isometric- no change in muscle length, static
isoinertial concentric- dynamic, produces tension while shortening muscles
isoinertial eccentric- dynamic, produces tension while lengthening muscles
factors affecting muscular strength
gender
fibre type- fast
joint angle
muscular power
explosive aspect product of strength and speed of movement
max intensity
factors affecting muscular power
gender
speed/direction
motor unit recruitment
speed
how fast you can move your body or body parts from one point to another
factors affecting speed
age
resistance to fatigue
fast twitch fibres
balance
body adapting to external forces acting on the body (gravity, friction, objects) with opposing internal forces from muscles
balance: static equilibrium
balance is maintained while body is stationary
balance: dynamic equilibrium
balance is maintained while moving
balance: changes to equilibrium
location
environment
position
factors affecting balance
centre of gravity(low)
body mass
base of support
coordination
ability to use different body parts together smoothly and efficiently
factors affecting coordination
stage of development
poor vision
cognitive limitations
reaction time
time between a stimulus and first response (baseball)
reaction time: steps
stimuli from environment
brain processes information
select a muscular response
activate a muscular response
