M1.		Glucose + oxygen   energy + carbon dioxide + water
[1]
M2.    (i)      Award one mark for a correct definition. An equation is 
acceptable.
Aerobic ‒ respiration in the presence of oxygen
Glucose + oxygen = energy + carbon dioxide + water
1
(ii)      Award up to two marks for an accurate description. For maximum
marks reference should be made to the intensity and length of time
of the situation.
e.g. activities that need long term energy systems, such as cross
 country running or long distance cycling
2
(iii)     Award one mark for a correct definition. An equation is acceptable.
Anaerobic ‒ respiration in the absence of oxygen
glucose → energy + lactic acid
1
(iv)    Award up to two marks for an accurate description. For maximum 
marks reference should be made to the intensity and length of time 
of the situation.
Activities that need short term energy systems such as 100m 
sprinting or weightlifting.

[6]

M3.    Training threshold
[1]
M4.    Award up to six marks for correctly explaining the training zones possible. Consideration also needs to be given to using these to improve endurance levels by increasing heart and breathing rates.
•        Anaerobic Training zone/ working at 80–90% of the calculated maximum heart rate/ for a short period of time or at a high intensity.
•        Aerobic zone/ working at 60–80% of the calculated maximum heart rate/ which should be maintained for at least 15 minutes for maximum effects or at a low intensity.
•        Training threshold/ aerobic threshold/ lower limit of aerobic zone/ must go above this to see benefit.
•        Anaerobic threshold/ upper limit of aerobic zone.
•        The intensity of the work is linked to the zones.
[6]

M5.	Award up to four marks for a full explanation of how training zones could improve her cross country running.
•        Cross country is an aerobic or endurance activity / she would need to go above the aerobic threshold / which is 60-80 % of maximum heart rate / at least 15 minutes / at low to moderate intensity / resulting in a more for efficient cardiovascular or cardiorespiratory or circulatory system / able to run more quickly
•        Anaerobic training zone, 80-90 % of maximum heart rate / is used for uphill sections or sprint finish / 60 seconds max / at high intensity / resulting in increased lactic acid tolerance.
