Physiologic considerations of therapeutic slideboard rehabilitation with an external loading device

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

Description
Summary: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. To determine if slideboard exercise while in a leg harness increases the metabolic and cardiorespiratory demands. Repeated-measures design. Athletic Training Research Laboratory. Sixteen volunteers from the university community. Subjects performed 2 graded slideboard exercise tests with and without the leg harness, each 2-minute stage ranging from 46 to 90 slides per minute. We measured maximal oxygen uptake, heart rate, blood lactate, respiratory exchange ratio, ratings of perceived exertion, and total time to exhaustion during each session. Significant decreases in maximal oxygen uptake and blood lactate were observed when the leg harness was used. Performance was hindered when subjects wore the leg harness during the slideboard exercise.
