Why the study?
Does altering central blood volume via posture or water immersion affect cardiac performance during exercise?
Does altering central blood volume via posture or water immersion affect cardiac performance during exercise?
Changes in central blood volume induced by posture or water immersion significantly alter left ventricular dimensions during moderate exercise and heart rate during heavy exercise.
