2009 exam revision

• increase their base of support
• lower their centre of gravity

ectomorph - tendancy to have a low degree of masculture and low body fat, lading to endurance type activties

• Vasoconstriction –
• shrinking of the blood vessels causing an decrease in blood flow

• Vasodilation –
• widening of the blood vessels causing a increase in blood flow

vasodilation is where the blood vessels increase in size and become closer to the skin where heat can be radiated out of the body to the skin, to the enviroment, where the body sweats and it is evaporated away from the skin to surface the cooling of the body down.

• decrease in sweating
• increase in heart rate
• increase in blood thickness
• decrease in blood flow
• increased body temp

• thermoregulation becomes difficult as less oxygen will be delivered to the working muscles. this will reduce aerobic energy systems efficiency and the body will use lactic at a lower intensity - fatigue
• heat stroke is a result of excess heat and sweating, loss of body fluids as the body fluids drop and temp increases it can result in fatigue or nausea.

• increase muscular hypertrophy (muscle size) leading to increase strength and power. 
• - greater run up speed and acceleration
• - greater distance at take off
• also greater and more efficient requirement of FT fibres to increase muscular strength and fibre

• - reducing noise level as there is less distracting noise and irrevelant cue's
• - increase the intensity of the ball (colour)
• - close the skill down so the athlete can be able to recognise the skills smaller subroutines that make up the skill

• kor - external feedback based on the athletes outcome, if the skill was successful or not
• kop - feedback for the athlete based on the feel of the movement. can be internal (proprioceptors) or external (coach providing feedback on how to improve)

• injury
• change in technique
• fatigue or over-training
• boredom or over-arousal

• correct goal setting (SMART)
• optimal arousal
• positive reinforcement
• set smaller goals that can be monitored and measureable
