Markscheme

i. perceptual skills use a person’s senses ✔
e.g. an athlete hearing the call of a team-mate to pass them the ball ✔

Award [2 max].

Award [1 max] if no examples are given.

a.i.

motor skills use voluntary movement ✔
e.g. a player passing a ball to their team-mate ✔

Award [2 max].

Award [1 max] if no examples are given.

a.ii.

perceptual motor skill is a skill where a person uses their senses to help execute a movement ✔
e.g. when passing a football, a player is aware of how much they are swinging their leg to impart the force to the ball, which they are looking at with their eyes ✔

Award [2 max].

Award [1 max] if no examples are given.

a.iii.

consistency:
the professional will be more consistent with their putts and be less variable in the ball’s placement ✔

accuracy:
the professional will generally get the ball closer to the hole than a novice from the same spot ✔

control:
the professional will have greater control of their movements ✔

learned:
the professional will have spent a significant amount to time practising the skill ✔

efficiency:
the professional’s movements will be efficient and only have the movements which are necessary for correct execution ✔

fluency:
the professional’s movements will flow and be coordinated, enabling success ✔

Award [3 max] for a list.

Accept in the converse.

b.

genes code for specific proteins which are involved in many characteristics such as fast-twitch muscle fibres / height / lung capacity <which are beneficial to particular types of sport> ✔

genes are expressed as phenotypes ✔

genes affect the potential to perform a certain skill ✔

however characteristics are influenced by multiple genes ✔

genes can be switched on or off depending on internal or external factors ✔

e.g. the correct or incorrect diet will influence the growth of an individual ✔

e.g. being active and doing exercises will trigger the body to respond and adapt / training enables individuals to perform to maximise their genetic potential ✔

despite environmental factors <e.g. training> performance is limited by a genetic ceiling ✔

c.

 

Award [3 max] for either.
