We support the proposed approach to introduce an annual Activities and Outcomes Report. 8. Explain why RV does not change with exercise. Based on these types of changes we speculate that active expiration during exercise in humans may be controlled by a combination of locomotor-related feed-forward and lung volume related feed-back mechanisms. During exercise, the depth of respiration increases. FRC is functional residual capacity is the amount of air left in the lungs after complete exhalation. ERV+RV=FRC. Volume of air remaining in the lungs at the end of maximal expiration. 6. Exercise-induced reductions in EELV occurred in all subjects, averaging 0.3 L (-0.1 to -0.7 L) in light exercise and 0.79 L (-0.5 to -1.2 L) in heavy or maximum exercise. The FRC supervises how companies comply with its Stewardship Code of governance best practice, requiring them to explain in a “clear and compelling” way if they choose to ignore some parts. the ERV decrease with exercise asssuming that the volume of air was exhaled more than being enhaled at the time. Although the mean (SE) end expiratory chest wall volume was 541 (118) ml lower (p<0.001) at the end of exercise, the endurance time was unchanged by the bronchodilator.
