The effect of dynamic intermittent hypoxic conditioning on arterial oxygen saturation.

Background: Increases in arterial oxygen saturation (SaO2) in response to intermittent hypoxic exposure (IHE) are well established. However, IHE protocols have historically involved static hypoxic environments. The effect of a dynamic hypoxic environment on SaO2 is not known.

Selective serotonin reuptake inhibitors and rhabdomyolysis after eccentric exercise.

Purpose: The purpose of this report was to review three cases of clinically significant rhabdomyolysis that developed in research subjects after completing an eccentric exercise protocol. All three cases occurred in subjects who reported use of selective serotonin reuptake inhibitors (SSRI).

Methods: Sixty-three subjects enrolled in the study.

Physiologic considerations of therapeutic slideboard rehabilitation with an external loading device.

Context: Slideboard exercise is consistent with the American College of Sports Medicine guidelines for exercise intensity of 55% to 90% of maximal heart rate or 40% to 85% of maximal oxygen uptake.

Objective: To determine if slideboard exercise while in a leg harness increases the metabolic and cardiorespiratory demands.

Design: Repeated-measures design.
