Purpose: This study investigated the effects of home-based exercise intensity on the aerobic capacity and 1 year re-hospitalization rate in patients with chronic heart failure (CHF). Methods: Forty seven patients with CHF (males 33, females 14, age $61.3{\pm}9.8years$) participated in this study. The patients were allocated randomly to 3 groups in accordance with home-based exercise intensity: no home based exercise (NHE, 40%, n=19), moderate intensity home-based exercise (MIHE, 43%, n=20), and high intensity home based exercise (HIHE, 17%, n=8). All patients completed the symptom-limited cardiopulmonary exercise (CPX) test safely at the cardiac rehabilitation hospital. Results: The NHE group significantly showed lower peak $VO_2$ and a higher $VE/VCO_2$ slope than the MIHE (p<0.05) and HIHE (p<0.01) groups. On the other hand, the NHE group did not show significant differences in the other hemodynamic responses, such as heart rate (HR) max, HR reserve, maximal systolic blood pressure (SBP), and SBP reserve. Nine out of 19 NHE patients (47%) were re-hospitalized related to heart disease and two out of 20 MIHE (10%) patients were re-hospitalized, but nobody in the HIHE group were re-hospitalized within 1 year from the CPX test. Conclusion: In patients with CHF, home-based self-exercise is one of the important factors for reducing the re-hospitalization rate. In addition, improved aerobic capacity is strongly associated with a lower re-hospitalization rate. In particular, re-hospitalized CHF patients showed significant differences in respiratory parameters and hemodynamic parameters compared to the non-re-hospitalized patients.

본 연구는 심근경색 환자에서 젊은 환자군과 60세 이상의 노인 환자군에서 심장 재활이 심폐운동 기능에 미치는 효과를 비교하고자 하였다. 2012년에서 2015년까지 심장 재활을 실시하였던 환자 중 외래 경과 관찰중인 환자의 기록을 후향적으로 분석하였다. 총 46명 (60세 이상의 노인 18명, 28명의 60세 미만의 젊은 환자군)이 연구에 포함되었다. 대상자들은 초기 운동부하 검사 결과를 바탕으로 심장재활 치료실에서 심전도 감시 하에 유산소 운동요법을 시행하였다. 심폐기능은 심장재활 실시 전, 후로 운동부하 검사에 의해 평가되었다. 심장재활을 실시하기 전 시행한 운동 부하 검사에서 최대 산소소모량, 최대 운동시의 신진대사 해당치, 무산소 역치 지표 등이 60세 이상의 노인에서 의미 있는 운동 기능 저하가 관찰되었다(p<0.05). 심장재활 전과 후의 운동 능력을 비교하였을 때, 두 군에서 최대 운동 가능시간, 최대하 심근부담률, 최대 심박수, 안정시 심박수, 최대 산소 소모량, 최대 산소소모량 측정시의 최대 환기량, 최대 운동시의 신진대사 해당치, 무산소 역치 지표에서 통계학적으로 유의한 변화가 관찰되어(p<0.05), 심장재활 후 두 군 모두에서 운동기능의 개선의 효과가 있었다. 60세 이상 군과 60세 미만 군 두 군 사이에서 심장재활 전과 후의 운동능력 지표 변화율의 상대적인 비교 시에 최대 운동 가능시간, 최대 산소 소모량, 최대 운동시 신진대사 해당치, 무산소 역치 지표 등의 모든 운동 부하 검사 결과는 유사한 호전을 보였다. 한국에서 노인 환자의 심장재활 참여율과 전과율은 낮은 상태이다. 60세 이상의 노인 환자에서의 심장재활의 참여를 확대하는 것이 필요할 것으로 생각된다.

연구배경 : 폐암환자는 폐암자체 뿐만 아니라 만성기도질환을 비롯한 기존의 폐질환 및 심질환 등으로 폐기능이 감소한 경우가 많으며, 전신항암치료는 약제에 의한 부작용으로 환자들의 신체활동능력이 급격히 감소되는 것이 일반적이다. 운동은 안정상태에서는 알 수 없는심 폐기능 이상을 확인할 수 있는 좋은 방법으로 심혈관계 및 폐기능 이상은 이들 환자의 삶의 질을 결정하는 중요한 원인으로 작용할 수 있다. 본 연구는 전신항암치료 중인 국소진행성 폐암환자의 심 폐기능 변화를 안정시, 그리고 운동시 각각 측정하여 전신항암치료가 환자의 운동 능력에 미치는 영향을 평가하는 것이 목적이다. 방 법 : 조직화적으로 임상적 병기 IIIA의 비소세포암으로 진단되고 전신항암치료를 받고 있는 11명을 대상으로 치료 전, 그리고 매 주기 전신항암치료 직전 안정시 폐기능검사, Karnofsky performance scale, 체성분검사, 그리고 운동부하 심 폐기능검사를 실시하였다. 결 과 : 안정시 폐기능은 전신항암치료 전 후 유의한 변화는 없었으나 폐확산능의 경우 통계적인 의미는 없었지만 치료 전 기대값의 $89.7{\pm}34.1%$에서 치료 후 기대값의 $71.9{\pm}20.5%$로 상당히 감소하는 경향이 있었다. 호흡근의 기능을 평가하는 최대흡기압 및 최대호 기압 역시 전신항암치료 전 후 차이가 없었다. 전신 항암치료전 후 체성분 및 신체활동능력의 변화는 없었다. 3주기 전신항암화학치료 후 운동부하 심 폐 기능은 최대산소섭취량은 치료 전 기대값의 64.8%(17.9ml/kg/$m^2$)에서 치료 후 44.7% (12.6ml/kg/$m^2$)로 감소하였고 (p<0.05), 산소맥은 치료 전 기대값의 63.5% ($7.0{\pm}1.7ml$/beat)에서 치료 후 46.3% ($5.2{\pm}2.1ml$/beat)로 감소하였다(p<0.05). 결 론 : 전신항암치료 후 짧은 기간 내 체성분 변화와 안정시 폐기능의 저하는 없지만 최대산소섭취량 및 산소맥은 감소하여 운동에 대한 심기능 및 폐기능의 허용한계는 감소한다. 그러나 이러한 결론은 전신항암치료 후 짧은 기간 내의 변화로 장기적인 전향적인 연구가 필요하리라 생각한다.

The purpose of this study focused how to show physiological responses comparing exercise group and non exercise group for progressive maximal wheelchair ergometer exercise loading in complete paraplegia. It also examined the various factors which would be influenced physiological responses. Sixteen subjects have been investigated in this study, and the subjects are divided into two groups as follows: 1) exercise group (7 subjects) 2) non exercise group (9 subjects). Each test was terminated by physical exhaustion and/or an inability to maintain a flywheel velocity. The results were as follows: 1) No difference was noted in pulmonary function test between two groups. 2) $\dot{v}$ Emax value during maximal exercise was significantly different between the groups (p<0.05). The mean $\dot{v}$ Emax of exercise group was $69.67{\ell}/min$, non exercise group was $41.47{\ell}/min$. 3) $\dot{v}$ $O_2max$(${\ell}/min$) value during maximal exercise was significantly different between the groups (p<0.05). The mean $\dot{v}$ $O_2max$(${\ell}/min$) of exercise group was $1.72{\ell}/min$, non exercise group was $1.15{\ell}/min$. 4) $\dot{v}$ $O_2$ max(ml/kg/min) value during maximal exercise was significantly different between the groups (p<0.05). The mean $\dot{v}$ $O_2max$($ml/kg{\cdot}min$) of exercise group was $25.99ml/kg{\cdot}min$, non exercise group was $18.61{\ell}/min$. 5) Maximal heart rate(HRmax) value during maximal exercise was significantly different between the groups (p<0.05). The mean HRmax of exercise group was 180.43 beats/min, non exercise group was 175.00 beats/min. 6) $\dot{v}\;E/\dot{v}\;O_2$ value during maximal exercise was not significantly different between the groups (p>0.05). The mean $\dot{v}\;E/\dot{v}\;O_2$ of exercise group was $36.36{\ell}/{\ell}\;O_2$, non exercise group was $45.46{\ell}/{\ell}\;O_2$. Considering the results which explore the exercise group with paraplegia has shown the maximal aerobic power compared with non exercise group, regular and consistent physical training is highly assumed as a main factor to improve cardiopulmonary fitness.

Purpose : This study aimed to investigate the effects of 12 weeks of resistance exercise on body composition, physical strength, blood lipids, and insulin. Methods : The study was conducted on 24 elderly women divided into two groups: 12 subjects in an exercise group and 12 subjects in a control group. Resistance exercise was performed for 50 minutes a day, three times a week, for the duration of 12 weeks, and body composition, physical strength, blood lipids, and insulin were measured before and after the subjects completed the program. For the statistical analysis, the mean and standard deviation (M±SD) of each variable were calculated using SPSS version 20, and a paired t-test and two-way repeated ANOVA were conducted to test for the differences before and after the resistance exercise. All significant levels were set to α=.05 as a result of the experiment. Results : Changes in body composition after the 12-week resistance exercise program did not show any significant difference based on the comparison between the groups, but when noting the values for body fat percentage and body in the control group before and after, a significant difference was shown in fat mass (p<.05). As for changes in physical fitness, significant differences appeared in flexibility, muscle strength, and stenotic force (p<.01) when the groups were compared. Regarding pre- and post-values within each group concerning flexibility within the exercise group, significant differences were shown in gender (p<.001), muscle strength (p<.05), (p<.01), muscle earth strength, equilibrium (p<.01), stenosis force, and cardiopulmonary earth force (p<.001). Also, comparisons between populations in changes in blood lipids the values before and after in each group, significant differences in glucose (p<.05) and insulin (p<.05) were shown in the exercise group. When comparing the values before and after in each population, a significant difference was shown in the control group (p<.05). Conclusion : When all the results were integrated, the 12-week resistance exercise program was found to enhance physical strength (flexibility, muscle strength, and coordination) and improve the blood sugar levels of elderly women. In particular, resistance exercise is believed to lower the prevalence of obesity, type 2 diabetes mellitus, and metabolic diseases by having a positive effect on insulin. Further studies are suggested to verify the effect on body composition and blood lipids by setting up a variety of exercise treatment methods (including subjects, exercise periods, exercise plans, and exercise intensity focuses).

This study aimed to compare the Korean Activity Status Index (KASI) with the cardiopulmonary exercise test (CPET) among patients with acute myocardial infarction. A total of 2,268 patients (85.4% male; mean age, 59.3±10.2 years; range, 23-90 years) diagnosed with acute myocardial infarction were enrolled in the Regional Center Myocardial Infarction Registry between July 2016 and June 2019. The KASI is a tool used to measure functional capacity by asking patients about their ability to perform specific activities and then scoring their responses. In contrast, CPET is the gold standard for assessing the objective functional capacity in patients undergoing cardiac rehabilitation. Peak oxygen uptake (VO_2peak) was used to analyze the correlation. Patients who completed two consecutive KASI and CPET evaluations during their first (KASI_1, VO_2peak_1) and second visits (KASI_2, VO_2peak_2) for cardiac rehabilitation were included in the study. The mean KASI_1 and KASI_2 scores were 43.3±14.3 and 49.8±13.9, respectively, and the mean VO_2peak_1 and VO_2peak_2 scores were 25.9±8.0 and 28.5±8.3, respectively. Both the KASI scores were significantly correlated with the measured VO_2peak during each visit, with correlation coefficients of 0.385 (P<0.001) and 0.346 (P<0.001), respectively. Moreover, the KASI score and VO_2peak had a linear relationship (VO_2peak_1=0.22×KASI_1+16.5, P<0.001; VO_2peak_2=0.21×KASI_2+18.2,VO_2peak_2=0.21×KASI_2+18.2, P<0.001). This study revealed that the KASI is a valid measure for the follow-up evaluation of the functional capacity of patients. These findings suggest that VO_2peak can be predicted using the KASI score in patients who do not undergo CPET.
