This study investigated the relation between seasonal variation of clothing weight and its resting metabolic rate to determine the relation between proper living temperature and cold/heat tolerance. Thirty six subjects(18 males and females, twenties) were composed to obtain the clothing weight(Total clothing weight) and resting metabolic rate for a year and grouped four seasons : spring(Mar∼May), Summer(Jun∼Aug), Fall(Sep∼Nov), and Winter (Dec∼Feb). The data of males and females were respectively divided into three groups by cluster analysis with clothing weight. 1. The resting metabolic rate of male (41.lkcal/m^3/hr) was higher than that of female (33,2kcal/m^3/hr), It is suggested there is gender difference in the resting metabolic rate(p<.001). 2. The resting metabolic rate of male and female was the highest in Winter. It is suggested there is seasonal variation in the resting metabolic rate (p < .001). 3. It was found that there was relation between clothing weight and resting metabolic rate. The difference of resting metabolic rate between Summer and Winter, which is profitable to adaptation to living temperature, was significant in light clothing weight in male as well as in female. 4. In comfortable sensation, most subjects responded that he/she felt 'comfortable' except Winter. However the heavy clothing weight group felt 'a little uncomfortable' throughout all seasons. In thermal sensation, most subjects responded that he/she felt 'neutral' . And then the heavy clothing weight group responded warmer in summer and cooler in winter than light clothing weight group. From the results, it was confirmed that male and female showed seasonal variations in clothing weight and resting metabolic rate. Also the resting metabolic rate of male and female was influenced by the clothing weight. In short, seasonal variation of resting metabolic rate was larger in light clothing weight group than in heavy clothing weight group. Therefore, light clothing weight group is advantageous in living temperature to improve cold/heat tolerance, and it also shows that living with the light clothing weight may enhance the degree of adaptation to change of living environment

신경아(Shin, Kyung-A) 한국웰니스학회 2015 한국웰니스학회지 Vol.10 No.4

안정시 심박수는 자율신경계 반응지표이다. 안정시 심박수와 대사증후군의 증가는 심혈관질환 이환율과 사망률의 위험요인이다. 본 연구는 한국 성인남성을 대상으로 안정시 심박수와 대사증후군 위험요인간의 관련성에 대해 알아보고자 하였다. 2010년 1 월부터 2012년 12월까지 J 종합병원 건강검진센터에서 종합건강검진을 실시한 20세 이상 80세 이하의 남성 14,252명을 대상으로하였다. 대사증후군은 미국심장학회에서 제시한 American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI, 2005)의 진단 기준에 따랐으며, 3개 이상의 위험요인을 가진 경우 대사증후군으로 진단하였다. 안정시 심박수는 대사증후군 위험요인과 관련이 있으며, 대사증후군 위험요인의 개수가 증가할수록 안정시 심박수는 직선적으로 증가하였다(각각 p<.001). 또한 염증지표인 고감도 C-반응단백질 및 백혈구수, 인슐린은 안정시 심박수가 가장 낮은 그룹에 비해 가장 높은 그룹에서 높게 나타났으며, 안정시 심박수가 증가함에 따라 대사증후군 유병률은 증가하였다(각각 p<.001). 결론적으로 안정시 심박수는 각각의 대사증후군 위험요인과 관련이 있으며, 안정시 심박수가 증가할수록 대사증후군 발병위험이 높았다. Resting heart rate is a recognized marker of autonomic nervous system response. Increased resting heart rate and metabolic syndrome are risk factors for cardiovascular morbidity and mortality. The author examined the cross-sectional association between resting heart rate and components of the metabolic syndrome in the Korean men. The study subjects were 14,252 males between 20-80 years who visited the health promotion center at a J General Hospital from January 2010 to December 2012. According to the American heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI) criterion, subjects with 3 or more risk factors were diagnosed with metabolic syndrome. The resting heart rate was correlated with metabolic syndrome risk factors and resting heart rate develops clustering of risk factors (respectively p<.001). Inflammatory markers in high sensitivity C-reactive protein and white blood cell counts and insulin were higher in the highest quartile than in the lowest quartile, the prevalence of metabolic syndrome increased with the in increase in resting heart rate (respectively p<.001). Resting heart rate was correlated with metabolic syndrome risk factors. The prevalence of metabolic syndrome increased linearly with the increase in resting heart rate.

Effect of Herbal Ephedra sinica and Evodia rutaecarpa on Body Composition and Resting Metabolic Rate: A Randomized, Double-blind Clinical Trial in Korean Premenopausal Women

Jung-Mi Park,Ho-Jun Kim,Jin-Ah Kim,Byeong-Pyo Ko 사단법인약침학회 2008 Journal of Acupuncture & Meridian Studies Vol.1 No.2

Background: As obesity is becoming an epidemic, diet programs, including low-calorie diets, are continuously being developed. It is generally believed that a low-calorie diet is commonly followed by a resting metabolic rate decrease and ultimate weight regain. Ephedra sinica and evodia rutaecarpa are known to have sympathomimetic and anti-obesity effects. Design and Objective: This study was a prospective; double-blinded, randomized and placebo-controlled clinical trial to evaluate the effects of ephedra sinica and evodia rutaecarpa on resting metabolic rate (RMR), body composition and shortterm safety in obese Korean premenopausal women on a low-calorie diet. Methods: One hundred and twenty-five otherwise healthy obese women (body mass index ≥ 25 kg/m2) were recruited and randomly assigned to three groups: ephedra group (n = 41), evodia group (n = 45) and placebo group (n = 39). Subjects were administered ephedra extract in capsules (pseudo-ephedrine 31.52 mg) or evodia extract in capsules (evodiamine 6.75 mg, rutaecarpine 0.66 mg) or placebo capsules as well as participating in a low-calorie diet for 8 weeks. Resting metabolic rate and body composition were measured at baseline, 4 and 8 weeks. Basic serum tests were performed to evaluate the short-term safety and lipid-lowering effects of the herbs. Results: All three groups showed significant body mass index (BMI) decreases, probably due to the low-calorie diet. Among the groups, the most prominent BMI-reducing effect was seen in the ephedra group. In RMR, no significant change in any group or significant difference among the groups was found. No significant adverse effects were observed in serum tests or in the self-questionnaire. Conclusion: Ephedra combined with a low-calorie diet was effective in reducing BMI. RMR change was not compensated for by the herbal medicines tried. RMR change seemed to be affected by constitution and body composition rather than by medicine. Ephedra and evodia were proven to be safe for short-term use in the herbal form.

본 연구는 체지방을 감소시키는데 효과적이라는 diacylglycerol (DG) 섭취와 유산소운동이 체구성비의 변화 및 혈중 지질 개선에 미치는 영향을 규명하고 안정 시 대사량 변화를 관찰함으로써 임상적 및 대사적 측면에서 비만 개선 효과를 규명하는데 그 목적이 있었다. 본 연구의 대상은 의학적으로 다른 질병을 동반하지 않은 비만 남자 대학생으로서 연구의 의의를 충분히 이해하고 자발적으로 참여 의사를 밝힌 사람으로 선정하였으며, 체지방 측정 후 25%미만인 자와 흡연자는 대상에서 제외하였다. 모든 피험자들은 기본검사와 사전검사가 끝난 후 세가지(D, E, DE) 집단에 6명씩 무선 배정하였다. 첫 번째 실험군(D)은 diacylglycerol 섭취 조건으로 12주 동안 diacylglycerol을 섭취하였고, 두 번째 실험군(E)은 12주 동안 러닝 트레이닝을 실시하였다. 마지막 세번째 실험군(DE)은 12주 동안 diacylglycerol 섭취와 유산소 트레이닝을 실시하였으며, 본 연구결과 모든 그룹에서 12주 동안의 그룹별 처치가 진행됨에 따라 체지방이 감소하는 경향을 보였다. 안정 시 대사량은 D그룹을 제외하고 모든 그룹에서 증가하는 경향을 보였으며 운동과 다이아실글리세롤 섭취에 따라 콜레스테롤의 감소가 일어났다. 추후 카테콜라민, CAMP, HSL, Insulin 등과 같은 지방대사와 관련된 항목들에 대한 추가적인 분석이 이루어짐으로써, DG섭취와 트레이닝의 비만개선효과를 보다 신뢰성 높게 예측할 수 있으리라 본다. The aim of this study was to investigate the combined effects of aerobic training and diacylglycerol ingestion on lipid profiles and resting metabolic rate changes in obese men. The subjects were divided into 3 groups: the Diacylglycerol group (D, n=6), aerobic training group (E, n=6), and diacylglycerol ingestion and aerobic training group (DE, n=6). Diacylglycerol was ingested and aerobic exercise training performed for 12 weeks. The information received from the research was calculated through a Windows SPSS/PC+ Ver. 12.0K statistics package to standardize the means and deviations for each group. Then, two-way repeated measures ANOVA was used to evaluate the research hypothesis. Percent body fat, blood lipid profiles and resting metabolic rate changes were tested to evaluate the combined effect of aerobic exercise training and diacylglycerol ingestion. The results of this study were as follows; DG ingestion was shown to have a positive effect on body weight and body fat, while having a negative effect on resting metabolic rate changes. However, aerobic training was shown to have a positive effect on all factors including body weight, body fat, and resting metabolic rate. In conclusion, DG ingestion and exercise training were not shown to have synergistic effects on resting metabolic rate changes, percent body fat and lipid profiles, while aerobic exercise training was shown to have a positive effect on resting metabolic rate changes, percent body fat, and lipid profiles. To investigate the therapeutic effect of DG ingestion and aerobic exercise for obese men, analysis of catecholamine, cAMP, HSL, or insulin sensitivity should be considered.

The purpose of this study is to examine the effect of long-term oral creatine supplementation combined with weight training on muscle mass, body composition, and resting metabolic rates. Ten participants are divided into 2 groups: Creatine supplement group, non-Cr supplement group. The creatine supplement group took 20 g of creatine monohydrate daily for the first 4 days and 5 g daily for the following 54 days. All the subjects performed onehour resistive training three times per week. Between creatine supplementation group and non creatinesupplementation group, there was no significant difference in resting metabolic rate,body weight, body fat percentage, body fat mass, lean body mass, urinary creatinine level, and one repetition maximum. However, creatine supplementation group had a tendency of being increased in resting metabolic rate, body weight, lean body mass, urinary creatinine, and one repetition maximum.

[Purpose] This study investigated the effects of exogenous lactate intake on energy metabolism during 1 h of rest after acute exercise. [Methods] Eight-week-old ICR mice were randomly divided into four groups: SED (no treatment), EXE (exercise only), LAC (post-exercise oral lactate administration), and SAL (post-exercise saline administration) (n=8 per group). The exercise intensity was at VO2max 80% at 25 m/min and 15° slope for 50 min. After acute exercise, the LAC and SAL groups ingested lactate and saline orally, respectively, and were allowed to rest in a chamber. Energy metabolism was measured for 1 h during the resting period. [Results] LAC and SAL group mice ingested lactate and saline, respectively, after exercise and the blood lactate concentration was measured 1 h later through tail blood sampling. Blood lactate concentration was not significantly different between the two groups. Energy metabolism measurements under stable conditions revealed that the respiratory exchange ratio in the LAC group was significantly lower than that in the SAL group. Additionally, carbohydrate oxidation in the LAC group was significantly lower than that in the SAL group at 10–25 min. No significant difference was observed in the fat oxidation level between the two groups. [Conclusion] We found that post-exercise lactate intake modified the respiratory exchange ratio after 1 h of rest. In addition, acute lactate ingestion inhibits carbohydrate oxidation during the post-exercise recovery period.

Clinical Usefulness of Serum Uric Acid and Resting Heart Rate in the Diagnosis of Metabolic Syndrome in Korean Adults

Kyung-A Shin 대한의생명과학회 2017 Biomedical Science Letters Vol.23 No.2

Elevated serum uric acid and resting heart rate are risk factors and predictors of metabolic syndrome. However, few studies have examined the optimal cutoff value for serum uric acid and resting heart rate to predict metabolic syndrome in Korean adults. Subjects for this study were 22,302 adults (average age 45 years old), who underwent health screening examination from January 2010 to December 2012 at the Health Promotion Center of one hospital in Gyeonggi-do for general health check-up. The uric acid and resting heart rate cutoff values were calculated by ROC analysis for metabolic syndrome. Elevated serum uric acid and resting heart rate were associated with an increased prevalence of metabolic syndrome in Korean adults. The optimal cutoff value for uric acid level to predict metabolic syndrome in adults was 4.95 mg/dL (male 6.35, female 4.55) and optimal cutoff value for resting heart rate to predict metabolic syndrome was 68 beats per minute (male 66, female 68). However, serum uric acid and resting heart rate were found to have limitations for the diagnosis of metabolic syndrome.

Accuracy of predicted resting metabolic rate and relationship between resting metabolic rate and cardiorespiratory fitness in obese men

( Do Kyung Kim ) 한국운동영양학회 2014 Physical Activity and Nutrition (Phys Act Nutr) Vol.18 No.1

[Purpose] The purpose of this study is to examine that not only the relationship of the resting metabolic rate (RMR) and cardiorespiratory fitness(VO2peak), but also the comparison between measured and predicted results of RMR in obese men. [Methods] 60 obese men (body fat>32%) were recruited for this study. They did not participate in regular exercising programs at least 6 months. The RMR was measured with indirect calorimetry and predicted RMR using Herris-Benedicte equation. The cardiorespiratory fitness was determined by directly measuring the oxygen consumption (VO2peak) during the exercise on the treadmill. [Results] The significance for the difference between the measured results and predicted result of RMR were tested by paired t-test. Correlation of measured date was obtained by Pearson correlation coefficient. The value of predicted RMR and measured RMR were significantly different in these obese subjects. (p<0.001). The difference between RMR cardiorespiratory fitness and cardiorespiratory fitness showed significant correlation (r=0.67, p<0.05). [Conclusion] The current formulas of predicted RMR have limited the evaluation of measured RMR for Korean obese men. Therefore, this study suggests that new formula should be designed for Korean in order to obtain more accurate results in obese.

고재면 ( Ko¸ Jae-myun ) 한국융합과학회 2021 한국융합과학회지 Vol.10 No.5

연구목적: 본 연구는 비만 남성을 대상으로 중강도와 고강도의 유산소 운동을 실시하여, 운동강도의 차이가 체구성 및 안정시 대사량(RMR) 그리고 혈중 지질 성분에 어떠한 영향을 미치는지 규명하고자 하였다. 연구방법: 연구대상자는 20-30대 비만 남성을 대상으로 중강도 유산소 운동 그룹(MIAE, N=10), 고강도 유산소 운동 그룹(HIAE, N=10)으로 구분하였다. 유산소 운동은 운동부하검사를 통해 측정된 V̇O₂max 기준으로 중강도 운동은 V̇O₂max 의 60~65%의 강도, 고강도 운동은 V̇O₂max의 80~85%의 강도로 설정하였으며, 8주간 주 3회의 횟수로 트레드밀에서 운동을 실시하였다. 운동 강도 차이에 따른 효과를 규명하기 위해 사전·사후 체구성 및 안정시 대사량을 측정하였고, 혈액 샘플을 채취하여 혈중 지질 성분을 분석하였다. 결과: 평균 운동시간의 경우 MIAE 그룹이 HIAE 그룹 보다 더 길었으며(P<.001), 체중 및 체지방률의 경우 두 그룹 모두 사전보다 사후에 유의한 감소를 보였다(P<.001). 그리고 제지방(LBM) 및 안정시 대사량(RMR)의 경우 HIAE 그룹에서 유의하게 증가하였다(P<.05). 그리고 혈중 지질 성분 중 Total cholesterol(TC), Low-density lipoprotein(LDL-C), Triglyceride(TG)의 경우 두 그룹 모두 유의하게 감소되었으며(P<.05), High-density lipoprotein(HDL-C)의 경우 HIAE 그룹에서 유의하게 증가하였다(P<.001). 결론: 8주간의 고강도 유산소 운동은 중강도와 비교하여 비만 남성에게 효과적임을 확인할 수 있었고, 안정시 대사량의 증진 그리고 혈중 지질 성분의 긍정적인 변화를 유도할 수 있음을 시사한다. Purpose: The purpose of this study was to investigate the effects of regular high- and moderate-intensity aerobic exercise on body composition, resting metabolic rate and blood lipid profile in obese man. Methods: The participants were recruited from a total of 20 obese man aged 20-30 years, and were high-intensity aerobic exercise(HIAE, n=10) and moderate- intensity aerobic exercise (MIAE, n=10) group. The participants were performed high- and moderate- intensity aerobic exercise three times a week for eight weeks, and body composition measurement, resting metabolic rate measurement, blood collection were performed before and after. Result: Mean exercise time was significantly longer in the MIAE group than in the HIAE group(P<.001). Body weight, and body fat(%) were significantly lower than pre both groups(P<.001). and lean body mass and resting metabolic rate were significantly higher in the HIAE group(P<.05). The total cholesterol(TC), low-density lipoprotein(LDL-C), Triglyceride(TG) concentrations were significantly lower than pre both groups(P<.05). and high-density lipoprotein(HDL-C) concentrations was significantly higher in the HIAE group(P<.001). Conclusion: High- intensity aerobic exercise not only decreases body weight and body fat in obese man, but also induces positive changes in resting metabolic rate and blood lipid profile.

The association of resting heart rate with diabetes, hypertension, and metabolic syndrome in the Korean adult population: The fifth Korea National Health and Nutrition Examination Survey

Yang, H.I.,Kim, H.C.,Jeon, J.Y. Elsevier Scientific Pub. Co 2016 Clinica chimica acta Vol.455 No.-

<P>Objective: Investigate the association of resting heart rate (RHR) with diabetes, hypertension and metabolic syndrome in a data set that represents the whole Korean adult population. Methods: The data of 18,640 adults, that represent the whole Korean adult population, was used to examine the association of resting heart rate (RHR) with blood related variables, diabetes, hypertension and metabolic syndrome. Results: Compared to participants with a RHR of < 60 beats per minute (bpm), participants with a RHR of 90 bpm had higher odds of diabetes {3.85 [95% confidence interval (CI) 2.14-6.90], 334 (95% CI 1.83-6.10)} and metabolic syndrome [3.55 (95% CI 2.19-5.74), 2.15 (95% CI 137-335)], for men and women, respectively. Furthermore, compared to the participants with normal BMI (< 23 kg/m(2)) normal RHR (< 80 bpm), participants with high BMI (>= 23 kg/m(2)) high RHR (>= 80 bpm) had higher odds of diabetes [2.51 (95% CI 1.83-3.46), 4.89 (95% CI 3.63-6.58)], hypertension [3.88 (95% CI 3.00-5.01), 2.61 (95% CI 2.07-3.28)], and metabolic syndrome [9.67 (95% Cl 7.42-12.61), 13.09 (95% CI 10.25-16.73)], for men and women, respectively. RHR shows a positive dose response relationship with the prevalence of diabetes and metabolic syndrome. The combined association of RHR with BMI increases the potency of RHR as a marker of diabetes, hypertension and metabolic syndrome. Conclusions: This study shows that RHR has an important role to play as a potential clinical measurement and prognostic marker. (C) 2016 Elsevier B.V. All rights reserved.</P>
