WebAlterations of aerobic fitness and muscle deoxygenation during a ramp incremental exercise test (GXT) were assessed on two occasions within a time-frame of 2.9 ± 0.1y in competitive youth cyclists. Nine cyclists (age, 14.5 ± 1.1y; peak oxygen uptake (V ˙ O 2peak), 62.6 ± 4.2 mL.min-1.kg-1) participated in this investigation. WebQuestion: 1. During exercise, the lungs and muscles require more oxygen than at rest. Oxygen is carried on the hemoglobin in red blood cells. The heart and its nervous system sensors control blood flow. Describe how the heart reacts to create homeostasis for the body during exercise. 2.As you rested post-exercise, what happened to the heart rate?
