Distinguish between cognitive and perceptual motor skills.
Cognitive:
cognitive skill in team games such as rules, tactics and game objectives are associated with decision making in game play and contribute to success on the field✔
success in checkers is not associated with the movement tasks✔
eg playing checkers requires mostly cognitive because it requires a lot of thinking✔
Perceptual Motor:
these skills involve the interpretation of environmental stimuli and the motor response to this sensory information✔
perceptual motor skills depend on high perceptual ability and are very important in activities that require the performer to adapt to the environment✔
most sports involve perceptual motor skills because they involve thought, interpretation and movement✔
eg dribbling with the ball to beat a defender in basketball✔
Award per skill type.
Award for an example per skill type.
State three different approaches to the classification of motor skills.
gross – fine✔
open – closed✔
discrete – serial – continuous✔
external – internal paced skills✔
individual – coactive – interactive✔
Award for three correct and for two correct.
Apply these three approaches to relevant sporting examples.
gross – fine
eg gross = kicking a ball/fine = throwing a dart✔
open – closed
eg open = receiving in badminton/closed = serving in badminton✔
discrete – serial – continuous
eg discrete = cartwheel/serial = tumbling routine in gymnastics/continuous = cycling✔
external – internal paced skills
eg external = batting in baseball/internal = pitching in baseball✔
individual – coactive – interactive
eg individual = shooting/coactive = swimming race/interactive = game of basketball✔
Award marks for examples of approaches stated in (bi), not for repeating the approach. Each approach stated in (bi) must have an example.
Award per classification approach.
Discuss the differences between a skilled and a novice basketball player.
skilled basketball player consistently performs at a high level eg regularly able to juggle ball with body over 100 times✔
skilled basketball player is accurate in execution of skills eg free throws on goal at a high percentage✔
skilled basketball player has the ability to control the ball eg under pressure from opposition✔
skilled basketball player has learnt skills eg practiced over many years✔
novice basketball player lacks efficiency eg passing and dribbling skills are executed poorly with mistakes apparent✔
skilled basketball player is goal directed eg when shooting at goal, passing to team mates, tackle attacking player✔
skilled basketball player movements are fluent eg completed with ease and grace✔
Accept answers in the converse.
Award if the underlined features are listed rather than discussed.
Evaluate the relative contributions of the three energy systems in a basketball player during a match.
relative contributions of the energy systems will be determined by the skill and fitness of the opposition / breaks in play/ pace of the game✔
relative contributions of the energy systems will be determined by the position of the player✔
relative contributions of the energy systems will be determined by the individual’s fitness level✔
ATP–PC:
short duration ‹one to ten seconds› at maximal intensity✔
fuel source Creatine Phosphate✔
no fatigue causing by-products✔
eg sprinting to stop an attacking move by opposition; goal shooter diving to save goal✔
Lactic acid:
moderate duration at a high intensity, between 20 seconds to two minutes✔
fuel source is anaerobic glycolysis/ glucose✔
lactic acid is a fatigue causing by-product and will see cessation of activity or reduced intensity✔
eg broken play up and down court for 20 + seconds✔
Aerobic:
play at lower intensity✔
fuel source is aerobic glycolysis/ glucose, fat and protein✔
no fatigue causing by-products✔
duration can continue as long as fuel supply exists✔
eg passing and low intensity play off ball✔
Award for first three marking points.
Award for just descriptions of energy systems.
Award per energy system.
Award for a valid example in a match per energy system.
