Adaptations and Responses
Short-term Responses
Increase in breathing rate more breathes used per minute
Maximal HR can reach as high as 60 from 12-15 at rest
Increased Tidal Volume-can increase up to vital capacity
Increase in Minute Ventilation- tidal volume x respiratory rate
Increased contraction of respiratory muscles
Increase in depth and frequency of breathing
Long-term Adaptations
Increased vital capacity
Stronger Respiratory Muscles- Diaphragm and Intercostal mucles
Greater pressure gradient produces faster air flow in and out of the lungs
Faster o2 and Co2 diffusion-gas exchange
Capillaries of the alveoli increase pulmonary blood flow
Steeper diffusion gradient
Increased tidal volume (TV) and minute ventilation (TE)
Increased number of functioning alveoli
Effects of a Warm-Up
Warmup gradually increases breathing rate
Diameter of airways increases due to change in smooth muscles
Respiratory muscles prepared for exercise, increased blood flow.
More oxygen to the working muscles
Effects of a Cool-Down
Gradual decrease of pre- exercise heart rate
BR remains elevated for up to 2 hours after exercise
Breathing rate remains higher than at rest to remove waste- Co2
Blood pressure to return to normal at a slower pace.
