Abstract

The purpose of this study was to investigate association between HRR and serum lipids, low exercise capacity in metabolic syndrome patients. All subjects(N=71) devide to Control(52.85±.45yrs) and Metabolic Syndrome(52.49±5.71yrs), Compared to HRR and Thought regression analysis observed to association of metabolic syndrome with poor heart rate recovery and low exercise capacity, metabolic risk factors. we used to bruce protocol with submax treadmill exercise test and heart rate recovery 1min(HRR1min) was calculated as peak heart rate during exercise minus heart rate 1 minute into recovery. In conclusion, Control compared to Metabolic syndrome were showed significantly higher BMI, % body fat, fasting glucose, TG, Rest and Peak BP, Rest and Peak RPP and significantly lowerO2peak, HRR1min, Exercise time. also, Poor HRR1min correlated to TG(r=-.447, p=.002), HRrest(r=-.473, p=.001), DBPpeak(r=-.501, p=008), O2peak, (r=.409, p=.008). Metabolic syndrome is associated with autonomic dysfunction and Poor heart rate recovery may have prognostic factor in prediction of vascular events in patients with metabolic syndrome.

본 연구의 목적은 중년의 남자 71명을 대상으로 대사증후군(52.49±5.71yrs)과 대조군(52.85±.45yrs)으로 나누고 두 집단의 회복기 심박수(HRR)를 비교하고, 저조한 회복기 심박수와 운동능력, 대사적위험요인과의 관련성을 조사하였다. 모든 대상자들은 bruce protocol을 사용하여 최대하운동부하검사(GXT)를 실시하였으며 회복기 심박수 1분(HRR1min)은 운동중 최고심박수(HRpeak)에서 회복기 1분(Recovery1min)의 심박수를 뺀 값을 사용하였다. 이상의 결과를 종합해 볼 때, 대조군에 비하여 대사증후군(MS) 환자의 체질량지수(BMI), 체지방율(%body fat), 공복시혈당(fasting glucose), 중성지방(TG), 안정시와 운동중 수축기 및 이완기 혈압(Rest & Peak BP), 안정시와 운동중 심근산소소모량(Rest & Peak RPP)이 유의하게(p<.05) 높았으며 회복기심박수 1분(HRR1min)과 최고산소섭취량(VO2peak), 운동시간(Exercise time)은 대조군에서 유의하게(p<.05) 높았다. 또한 대사증후군(MS)환자에서 회복기 심박수 1분(HRR1min)과 중성지방(TG), 안정시심박수(HRRest), 운동시 이완기혈압(DBPPeak), 최고산소섭취량(VO2peak)이 유의하게(p<.05) 높은 상관관계를 나타냈다. 따라서 대사증후군(MS)은 자율신경계 기능이상(AD)과 관련이 있으며 저조한 회복기 심박수는 나아가 심혈관계 합병증을 예측할 수 있는 인자로 판단된다.
