Minute ventilation ____ in line with exercise intensity (as both TV and f increase). In sub maximal- ____ exercise, minute ventilation can ____ (as demand for O2 is being met and waste removal). 1. ____- due to the release of adrenaline, which stimulates the RCC. 2. ____- at the start of exercise due to neural stimulation of RCC by muscle and joint ____. This causes increased f and TV leading to increased VE. 3. Sub Max- Slower increase/ plateau- in sub-maximal proprioreceptors, but with additional stimulation from temperature and chemoreceptors due to an ____ in temperature, CO2 and LA levels and a ____ in O2 in the blood. This represents a steady state where the demands for oxygen by the muscles are being met. 3. Maximal intensity- Continued but slower increase in VE towards maximal values (____ plateaus but ____ increases) 4. Rapid decrease in VE- once exercise stops due to ____ demand for O2 (cessation of proprioreceptor and decreasing chemoreceptor stimulation). 5. Slower decrease- towards resting VE values. The more intense the exercise period the longer the elevated level of ____ required to help remove the increased by-products of exercise, e.g. LA.
