OCR A level PE - Environmental Affects on Exercise

What is the optimal time for altitude training considered to be?

• 2-3 weeks

• 6-8 weeks

• 8-10 weeks

• 4-6 weeks

What is hypoxia?

• A condition where respiring tissue is deprived of adequate CO2

• A condition where respiring tissue is deprived of adequate O2

• A condition where respiring tissue is deprived of adequate H2O

• A condition where respiring tissue is deprived of adequate N2

What is altitude acclimatisation?

• The process of the body adjusting to increased availability of O2

• The process of the body adjusting to decreased availability of O2

• The process of the body adjusting to increased availability of CO2

• The process of the body adjusting to decreased availability of CO2

What is the effect of altitude on the cardiovascular and respiratory systems pre-acclimatisation?

• Increased efficiency

• Decreased efficiency

• No effect

• Improved strength

What is the effect of altitude on the cardiovascular and respiratory systems post-acclimatisation?

• No effect

• Decreased efficiency

• Improved strength

• Increased efficiency

What is detraining?

• When exercise intensity increases causing an increase in physiological adaptations

• When exercise intensity reduces causing a decrease in physiological adaptations

• When exercise intensity reduces causing an increase in physiological adaptations

• When exercise intensity increases causing a decrease in physiological adaptations

What is the core body temperature?

• 38°C

• 37°C

• 35°C

• 36°C

What is thermoregulation?

• The process that allows the body to maintain its bone temperature

• The process that allows the body to maintain its skin temperature

• The process that allows the body to maintain its core body temperature

• The process that allows the body to maintain its muscle temperature

What is the effect of heat on the cardiovascular and respiratory systems?

• Improved strength

• No effect

• Decreased efficiency

• Increased efficiency

Cardiovascular adaptations to altitude training are (more than one)

• increased capillary density around alveoli and muscles

• increased release of erythropoietin (EPO)

• increased haemoglobin content in the blood

• increased capacity for diffusion during external and internal respiration

• increased surface area of alveoli
