| Abstract |
Introduction Individuals with dyslipidemia has lower aerobic capacity and ventilatory threshold or VT during exercise. The aim of this study was to evaluate the ventilatory threshold in overweight dyslipidemic females, BMI 27.2±0.76, without drug treatment. Methods Seven overweight dyslipidemic females aged between 47±4.74 yr. (Total cholesterol 198.3±9.59 mg/dL, Triglyceride 188.6±31.94 mg/dL, LDL-c 124.5±10.42 mg/dL and HDL-c 50.4±5.6 mg/dL) underwent a graded exercise testby the electricalmagnetically braked cycle ergometer (Corival, Lode, The Netherlands). Each subject performed exercise starting at 30 watts to 70 watts depending on individual fitness status Then the workload increased by 10 watts every 3 minutes until HR reached 85% HRmax. VO2, peak was calculated from the VO2, and HR relationship. Then the workload was calculated from the VO2, peak and workload relationship. The cycling speeds had to be maintained not lower than 60 rpm. Expired gas was recorded and analyzed by a gas analysis system (Cortex, Germany). The ventilatory threshold was determined by two methods 1) Ventilatory Equivalents Method 2) V-Slope method. This study complies with the guiding principles for experimental procedures found in the Declaration of Helsinki of the World Medical Association. The ethics committee that approved our work is Khon Kaen University Ethical Committee. In addition, it is not published at other meeting prior to the WCPT-AWP & PTAT 2017 Congress. Results The results show that ventilatory threshold (VT) was at 50 watts, 58.24±1.72 % of VO2, peak, 72.27±1.59 % of HRmax. VO2 at VT was 0.81± 0.04 (L/min), VCO2 at VT was 0.87±0.07 (L/min), RER at VT was 1.06 ± 0.06, Heart rate at VT = 126±4 (/min) and VO2, peak = 22.2±1.42 (ml/kg/min). Discussion The results suggest the work load at VT may be used to train or evaluate for aerobic capacity in overweight dyslipidemic females for improve aerobic capacity and alteration on the blood lipid profile. |
