Cardiometabolic Responses Of Body-weight Exercises With And Without Vibration: 3183 Board #52 June 2 8 00 AM - 9 30 AM

PURPOSE: This investigation examined cardiometabolic responses of body-weight (BW) exercises with and without concurrent vibration. METHODS: Eight men and six women performed a BW exercise protocol either on the floor (BW–V) or with a vibration platform (BW+V) in a randomized order. The BW exercise protocol consisted of three circuits of eight calisthenics-based exercises performed using Tabata intervals. Vibratory frequency and amplitude were set at 40 Hz and 4 mm, respectively. Oxygen uptake (VO2), heart rate (HR), expired ventilation (VE), and respiratory exchange ratio (RER) were measured throughout the protocol and during 30 min recovery. Blood lactate concentrations ([La] were determined at rest and at the end of BW-V and BW+V. RESULTS: The mean (±SE) VO reached 22.11 (±0.51) and 23.28 (±0.82) ml[BULLET OPERATOR]kg-1[BULLET OPERATOR]min-1 or 48% and 50% of VO max in BW-V and BW+V, respectively. The mean HR reached 156.63 (±4.15) and 162.22 (±4.40) beats[BULLET OPERATOR]min-1 or 80% and 83% of HRmax in BW–V and BW+V, respectively. During the protocol, while the mean VE was greater (p=0.031) in BW+V than BW-V, no differences were seen for VO2, RER, and HR between the two conditions. During recovery, while mean VO2 was greater (p=0.002), and RER was lower (p=0.033) in BW+V than BW-V, no differences were seen for VE and HR between the two conditions. [La] were significantly elevated, but remain similar between the two conditions. CONCLUSION: Performing three circuits of eight BW exercises using Tabata intervals produces a sufficient increase in cardiometabolic responses. Metabolic potentiation associated with combining vibration with BW exercises seems to be influenced by how the exercises were carried out on a vibration platform.
