Cardiorespiratory And Metabolic Responses To Low-Intensity Blood-Flow Restricted Running, Violet E. Sullivan, Amanda P. Ares, Summer B. Cook Ph.D.

Honors Theses and Capstones

Low-intensity (LI) aerobic exercise with blood-flow restriction (BFR) increases heart rate (HR), oxygen consumption (VO₂), and ratings of perceived exertion (RPE), sometimes to similar levels as high-intensity (HI) exercise. Distance runners may benefit from LI-BFR running in periods of reduced volume or intensity, possibly due to injury. PURPOSE: To compare HR, VO₂, blood lactate (BLa), and RPE during LI-BFR running and HI running without BFR. METHODS: Fifteen female distance runners (age 23+4yrs, height 1.67+0.50m, body mass 57.6+5.7kg, VO₂max 51.0+4.5mL•kg^-1•min^-1) completed three randomized 12-minute running conditions: LI control (40% VO_{2 …}
