PA and the Lungs (lecture 13) Flashcards
Describe some of the adaptations that occur to the CV system as a result of exercise training?
Increased oxygen uptake, increased plasma volume and blood vessel function.
VO2 Max, blood volume and metabolic control all increase whereas bp decreases
What does exercise do the risk of hypertension?
Decreased risk by 50%, typically a 7mmHg decrease in blood pressure occurs, just 2mmHg is significant (CHD decrease 7%,stroke 10%)
What is Asthma and some of the triggers?
Asthma is a condition that causes coughing, wheezing tight chest and breathlessness.
Causes inflammation of the bronchi which makes them more sensitive than normal
Triggers include dry, cold air, animal fur pollen, EIB (can occur during or right after exercise)
What stops airway obstruction?
Breathing air at 37 degrees, maximal airway obstruction occurs at colder temperatures
How can exercise help asthma?
- Improving lung function - reducing worry about attacks
- increasing confidence
- losing weight
What is COPD?
Chronic obstructive pulmonary disease is the name given to the collection of chronic bronchitis, emphysema and asthma
What does COPD lead to?
Damaged airways and lung tissue resulting in obstruction to airflow
Describes the patient inactivity cycle in COPD?
Cycle occurs where patients feel breathless, therefore do less activity, muscles weaken, then muscles use more O2 and the cycle continues
How can inactivity cycle be broken?
With PA and pulmonary rehabilitation
PA biggest predictor of mortality in COPD patients
Exercise benefits of COPD?
Increased O2 capacity, decreased minute ventilation, FEV2 decline reduced, cardiac function improved
Decreased anxiety about breathlessness, lower bp, reduced social isolation, positive effects on co-morbidities
When should an individual take caution to exercise with COPD?
If their SaO2
Advice for health professionals dealing with COPD patients?
Should use an RPE scale and ensure a thorough warm up/cool down
Consider interval training
