Environmental Factors Effecting Exercise

What is the key issue with exercising at higher altitudes?

• Low percentage of oxygen in the air

• 'Thin air'

• Lower Partial Pressure of Oxygen

• Higher Partial Pressure of oxygen

If partial pressure of oxygen is lower, this will lead to...

• Quick removal of carbon dioxide

• Decreased transportation of oxygen to the working muscles

• Decreased saturation of haemoglobin

• A lower rate of diffusion

When the body cannot utilise the oxygen it needs, the below happen...

• Q increases at high intensities

• SV decreases

• HR increases

• Q decreases at high intensities

These physiological effects lead to...

• Early fatigue

• Delayed fatigue

• Lower VO2 MAX

• Higher VO2 MAX

What is the name given to the process of the body 'adapting to it's environment'?

During acclimatisation, the body produces more of which hormone?

Increased EPO results in...

• Stabilised breathing rate

• Reduced SV and Q

• Increased oxygen carrying capacity

• Increased red blood cell production

The body is thermoregulated to within 1⁰C of what temperature?

• 35

• 36

• 37

• 38

If our body gets too hot, we sweat.

If we sweat excessively, what physiological effects can happen?

• More EPO

• Increased Blood Viscosity

• Reduced blood plasma

• Fewer red blood cells

In addition to...

• Higher HR

• Lower HR

• Higher SV

• Lower SV
