Which respiratory change occurs after regular physical training?
1
Decreased lung capacity
2
Increased tidal volume
3
Decreased breathing efficiency
4
Reduced oxygen uptake
Answer and Solution
Answer
B. Increased tidal volume
Solution:
After regular physical training, lung capacity increases due to enhanced alveolar function and muscle efficiency. It allows for greater amounts of air to be inhaled and exhaled, hence 'Increased tidal volume' is the correct answer.
