what is avo2 diff
The difference in the amount of oxygen in the arterial blood and venus blood
How much oxygen the muscles use
What are the three different muscle fiber types
Type 1 - Slow Twitch
Type 2a - Fast Twitch (someonewhat fatuige resistant)
Type 2b - Fast Twitch
What’s the difference between Type 2a and Type 2b
Type 2a is more fatigue resistant than 2b
Identify Newtons First law of motion
An object will remain in motion unless acted upon by an unbalanced external force
What is Newtons second law of motion
the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass
F=MA
What is Newtons third law of motion
For every action there is an equal and opposite reaction
Define impulse
The time which force is applied over
what is the impulse formula
J=FT
J- impulse
F-force applied
T=time over which the force is applied
define Vo2 max
The maximum amount of oxygen in liters that the body can inspire, transport and used by the body to produce energy.
define intrinsic motivation
motivation that comes from participating in the activity itself and the enjoyment that comes from it.
e.g trying to beat a PB or motivated by playing well
explain extrinsic motivation
comes from an external source
such as rewards and recognition.
examples include medals, trophies, certificates and vouchers.
explain broad-external focus (assess)
focusing on several cues in the environment
e.g a goalkicker scanning the field before taking a shot
explain narrow-external focus (act)
focusing on one or two external cues
e.g tennis player focusing on their ball toss to serve
explain broad-internal focus (analyse)
Analyzing and planning the task by reviewing thoughts and emotions
e.g golfer considering shot selection before shot
explain narrow-internal focus (prepare)
focusing on internal cues and mentally rehearsing the skill
e.g visualizing the shot before a free throw in basketball
define aerobic power
The maximum rate of energy that can be produced from the aerobic system
explain the stretch short cycle
a rapid eccentric contraction, lengthening the muscle which is immediately followed by an explosive concentric contraction

observation
evaluation
error correction
what are the different types of constraints
