Deck 6 Adaptations and additional factors Flashcards
1 There are a few additional factors that can affect your respiratory system: what are they?
- Asthma
- The effects of altitude
2 What is asthma and what id the result of this?
A common condition where the airways of the respiratory system can become restricted, making it harder for air to enter the body. The result; coughing, wheezing or shortness of breath.
3 How does asthma occur?
Asthma causes the band of muscles surrounding the airway to contract and tighten.
4 Why does asthma have a negative effect on sports performance?
Asthma will have a negative effect on sports performance as it restricts oxygen delivery to working muscles
5 How does an inhaler help Asthma?
An inhaler helps to relax the band of muscles surrounding the airways, supporting the movement of air/gas through the system
6 Why do sports performers chose to train at altitude?
lower air pressure and the oxygen particles are farther apart
7 Altitude training creates two effects. What are they?
This creates two effects;
Short term effects.
Long term effects.
8 List the 5 short term effect of altitude training
Less oxygen in the atmosphere; oxygen supply to alveoli is less
Reduces diffusion gradient of oxygen
Less oxygen combining with haemoglobin; less 02 in the blood
Reduction in air pressure causes increase breathing rate
Performance at altitude decreases; fatigue sets in sooner
9 List the 5 long term effect of altitude training
Effects seen when returning to sea level
Increased EPO level (erythropoietin; stimulates RBC production)
Increases RBCs; greater oxygen carrying capacity
Can work aerobically at a higher intensity without fatigue
Improves recovery time after exercise
10 State the four negative effect of altitude training
Due to hypoxia (body being deprived of oxygen)
Altitude sickness, headaches and dizziness
Financially unsustainable
Time away from family
