Assessment of Endurance Capacity by Gas Exchange and Heart Rate Kinetics During Physical Training (EKE)

Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
The preservation of aerobic capacity is a major goal of exercise countermeasures during weightlessness. The effectiveness and the time-consumption of the training depend on the appropriate choice of exercise protocols, and it is necessary to monitor endurance capacity throughout space flight. A widely used measurement for endurance capacity is maximal oxygen uptake (VO2 max) determined by incremental exercise tests until exhaustion.

Main objectives:
1) Development of a diagnostic tool for the assessment of endurance capacity from respiratory and cardiovascular kinetics in response to changes in exercise intensity.
2) Development of a physiological model to explore the delay and distortion of muscle VO2 signals during their travel to the lungs.
