6
Q

A group of amateur runners are attempting their first marathon. Some of the runners take advantage of the drinks offered to them during the race whilst others do not.

Evaluate the actions of the runners who do not take advantage of the drinks available. (3)

A
  • More likely to suffer from dehydration, which has a negative effect on running performance (1)
  • More likely to suffer from increases in heart rate so the heart has to work harder to supply oxygen to the muscles when running (1)
  • Reduction in blood flow to working muscles / thicker (viscous blood) which means less oxygen to the muscles and it is harder to remove waste products – slows recovery so harder to continue in the marathon (1)
  • Increase in body temperature so body could overheat during the race and become faint / pass out and cannot carry on (1)
  • Muscle fatigue more likely which could cause cramps so cannot carry on (1)
7
Q

  • Provides slow release energy supply / or endurance type activities or to delay fatigue / allowing performers to compete for longer. OR
  • Provides and increases the amount of glycogen or energy stored/ delaying tiredness / allowing the performer to be more effective at the end of an endurance or aerobic activity. OR
  • Aids recovery / reducing stiffness and soreness / so the performer can train again sooner.
9
Q

Explain how drinking water and other fluids could help to improve a sportsperson’s performance. (3)

A
  • Maintain hydration or prevent dehydration / to avoid cramp / so the performer is able to keep working hard or can work for longer / at a higher level.
  • Maintain hydration / to maintain focus or concentration / so the performer makes fewer mistakes / and can perform at a higher level.
  • Maintain hydration / provide electrolytes / allowing the body to replace lost salts / so the performer is able to continue working for longer or faster or at a higher level.

23
Q

Diet is an important factor to consider when participating in a physical activity.

Explain how a carbohydrate loading diet could help an athlete to perform to the best of their ability in a half marathon. (4)

A

By eating (high-carbohydrate) meals such as pasta / which is a slow release energy source / in the three days before the half marathon / an athlete will increase the glycogen level in their muscles and liver / to its maximum/so an athlete would have more energy available during the run. / This would help to delay the onset of fatigue (or reduce levels of fatigue) / and could help their to maintain their performance in the later stages of the run / as glycogen is as an immediate reserve source of available glucose for muscle cells. / Their liver will also readily break down its stored glycogen into glucose / and send it through the blood stream as fuel for their muscles.

24
