aerobic power
aeoribc power is the rate of energy releasse by processes that depend on oxygen (aerobic respiration is the most important health related component
body cumpostition
anaerobic capacity
anaerobic capacity is defined as the maximal amount of adenosine triphosphate resynthesized via anaerobic metabolism during a specific mode of short duration maximal exercise
flexibility
balance
muscular endurance
is the ability of a muscle or muscle group to perform repeated actions or to maintain an isometric action for an extended period time
local muscular endurance refers to the muscle group involved in actions
muscular power
is the ability to exert a force rapidly, over a short period of time, related to strentgh force and speed velocity
power = force X velocity
fitness components
muscular stentgh
iso metric
muscle length us consistent (no change)
isoinertial
resistence is constent
concentric: external load is less, eccentric: exteral load is greater
lifting phase of a bicep curl
isokenetic
speed of motion is consistent
factors effecting muscular strength
muscle size, (cross section area)
fibre arrangment: fusiform or pennate
fibre type: slow or fast twitch
legnth tension relation ship: peak force is developed just beyond the resting length of a muscle
