Identify the main fuel source of energy for the brain. 

Using sporting examples, discuss the contribution of genetic factors to potential success.

glucose;

individuals inherit 50 % of their genes from each parent which will determine their athletic potential;

genetic factors can provide an advantage, but are not the sole determinant of success

OR

to achieve the full potential of genetic factors, appropriate nutrition and training are required;

genetic factors:

height/limb length: related to basketball, volleyball, gymnast, etc.;

muscle fibre type: linked to either aerobic/slow or anaerobic/fast;

anaerobic threshold: endurance event such as marathon, long distance cycling etc.;

lung capacity: endurance event such as marathon, long distance cycling etc.;

flexibility: linked to gymnastic or similar event;

Award [1] mark for each genetic factor with details as to how each genetic factor can lead to athletic success.

Max [1] for list of 2 or more genetic factors.

Need to identify which fibre type is responsible e.g. fast or slow.

Candidates generally demonstrated sound knowledge. However, many candidates misinterpreted the concept of fuel suggesting oxygen as the fuel and others offering ATP as their answer.

Candidates were often able to refer to the concept that both environmental and genetic factors may contribute to an individual's performance. With regards to providing a sporting example, when discussing a concept more application and detail needs to be provided. For example, candidates were required to identify a genetic trait and discuss how this would directly benefit a performer in a particular sport/event. Many candidates just identified the factor and identified a sport.
