  1. two bio mechanical principles to maintain stability
    • increase their base of support
    • lower their centre of gravity
  2. somatotype (marathon)
    ectomorph - tendancy to have a low degree of masculture and low body fat, lading to endurance type activties
  3. vasodilation and vascontrction define
    • Vasoconstriction –
    • shrinking of the blood vessels causing an decrease in blood flow

    • Vasodilation –
    • widening of the blood vessels causing a increase in blood flow
  4. explain the physiological importance of vasodilation in blood vessels in relation to temperature regulation
    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.
  5. physiological responses to dehyration
    • decrease in sweating
    • increase in heart rate
    • increase in blood thickness
    • decrease in blood flow
    • increased body temp
  6. explain two physiological responses to dehydration that can cause a decrease in performance
    • 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.
  7. how would polymetic training increase long jump performance
    • 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
  8. explain one way in which a coach will improve the anticipation of a non skilled GK
    • - 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
  9. explain the difference between knowledge of performance and knowledge of results
    • 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)
  10. suggest a reason for a autonomous learner to be associative for part of the season
    • injury
    • change in technique
    • fatigue or over-training
    • boredom or over-arousal
  11. suggest one strategy that would help an athlete to achieve a goal
    • correct goal setting (SMART)
    • optimal arousal
    • positive reinforcement
    • set smaller goals that can be monitored and measureable
