Expiratory flow limitation confounds ventilatory response during exercise in athletes

Article Abstract:

This article examines the effects of expiratory flow limitations on determining ventilatory responsiveness of trained long-distance runners during intense exercise. Results indicate that after controlling for flow limitations, a significant relationship was established between hypoxic ventilatory responsiveness and arterial hemoglobin levels in trained athletes.

Hemoglobin/myoglobin oxygen desaturation during Alpine skiing

Article Abstract:

This article investigates changes in muscle blood volume and tissue deoxygenation during giant slalom and Alpine skiing. Findings indicate that the lower posture assumed during slalom racing may be related to a increased restriction of blood flow and a greater desaturation of hemoglobin and myoglobin when compared to Alpine skiing.
