Abstract

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.

SETTING: Athletic Training Research Laboratory.

PATIENTS OR OTHER PARTICIPANTS: Sixteen volunteers from the university community.

INTERVENTION(S): 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.

MAIN OUTCOME MEASURE(S): We measured maximal oxygen uptake, heart rate, blood lactate, respiratory exchange ratio, ratings of perceived exertion, and total time to exhaustion during each session.

RESULTS: Significant decreases in maximal oxygen uptake and blood lactate were observed when the leg harness was used.

CONCLUSIONS: Performance was hindered when subjects wore the leg harness during the slideboard exercise.
