1. Describe the conditions at altitude that could limit the ability to perform physical activity. 2. What types of exercise are detrimentally influenced by exposure to high altitude and why?

3. When someone ascends to an altitude of over 1,500 m, describe the physiological adjustments that occur within the first 24 h.

4. Describe the theoretical advantage of living high and training low.

5. What are the health risks associated with acute exposure to high altitude and how can they be minimized?

1. Lower Barometric Pressure

2. Aerobic exercise

3. Basal Metabolic Rate Increase

4. improvements in some short duration sea-level performances

5. Vomiting, insomnia, dyspnea, nausea, and headache

Explanation:

1. Lower Barometric Pressure

-Hypobaric environment of the particular altitude

-Low atmospheric pressure or Hypobaria

Reduced atmospheric pressure

- Reduced PO2 air breathed in

Reduced PO2

-Caps pulmonary oxygen diffusion from the lungs

-Restricts O2 transport to the tissues

Low PO2 content in the air

-Also known as hypoxia

Hypoxia

-Low O2

Associated Low PO2 in the blood

-Hypoxemia

2. what types of exercise are detrimentally influenced by exposure to high altitude and why

aerobic exercise

The oxygen requirements of aerobic exercise leads to increased heart rate and, resulting tiredness within a short period of time

3. When someone ascends to an altitude of over 1500 m, describe the physiological adjustments that occur within the first 24 h

- Basal Metabolic Rate Increase

- Arterial PO2 Reduction

- Progressive Decrease In Blood plasma volume

- Blood pH increases

- Decreases in Pressure Gradient

- Drop in Alveolar PO2

- Increases in Ventilation

4. Describe the theoretical advantage of living high and training low

The logic in this system is that acclimatising the body to altitude by living there, and maintaining training intensity by training at sea level provides the harnessing of the gains of altitude exposure and avoiding some of the negative effects of altitude exposure. There are improvements in some short duration sea-level performances by keeping to the above technique.

5. Vomiting, insomnia, dyspnea, nausea, and headache

Consider the ascent rate, the altitude intended to be ascended, and the experience of the individual with the altitude to reduce the likelihood for symptoms to manifest.
