정용주(Jeong Yong-Ju),오재근(Oh Jea-Keun),김영주(Kim Young-Joo) 한국체육과학회 2010 한국체육과학회지 Vol.19 No.2
The aim of this study is to compare cardiac diastolic function and cardiovascular factor in male elite athletes according to training types. Thirty-two male university students(Runner, n=8; Bodybuilder, n=8; Cyclist, n=8; Control, n=8) were assigned to 1 of 4 groups. All groups measured cardiac diastolic function by echocardiography and VO₂max, RPP were measured by graded exercise test One-way ANOVA was used to compare variables among 4 groups. Then, Bonferroni was used as post hoc analysis. A significant level was considered as p<.05. The results are as follows; 1. E/A ratio was higher in Run group compared to Body and Cyc, Con groups(p<.05, p<.01, p<.05). DT was higher in Run and Cyc, Con groups compared to Body group(p<.01, p<.001, p<.05). E'/A' ratio was higher in Run group compared to Body and Con group(p<.001, p<.001 and Cyc group was higher than Body group(p<.05). E/E' ratio was higher in Run group compared to Body and Con group(p<.01, p<.05) and Cyc group was higher than Body and Con group(p<.01, p<.01). 2. Sub-RPP was lower in Run group compared to Body, Cyc, Con group(p<.001, p<.01, p<.001, Cyc group was lower than Con group(p<.05). Cyc group was lower than Con group(p<.05). VO₂max was higher in Run group compared to Body and Con group(p<.001, p<.001) and Cyc group was higher than Body and Con group(p<.001, p<.001). In conclusion, Run and Cyc groups were improved in cardiac diastolic function and cardiovascular factors.

The purpose of this study is to estimate the effect when performing Basic Gymnastics of New Millenium Health Work Out with providing Kilo calorie and exercise intensity. The subjects consisted of 32 women(age 30~69) in good health living in S city who understood completely Basic Gymnastics of New Millenium Health Work Out. Experiment is done following procedures. First day, Maximal oxygen consumption and peak VO₂ was recorded by performing graded exercise test to the subjects. Second, when the subjects were performing Basic Gymnastics of New Millenium Health Work Out, they were wearing K4b2 and it was recording heat rate, VO₂, and Kilo calorie of the subjects in real time. The results are as follows. 1. While performing Basic Gymnastics of New Millenium Health Work Out, there was no meaningful difference of Kilo calorie per minute in age groups(5.67±0.80㎉~6.79±1.40㎉) and also total Kilo calorie for six minutes between age groups didn't show a meaningful difference(34.03±4.83에서 40.74±8.44㎉). 2. The percentage of average VO₂ was in thirties (55.77±15.66), in forties(64.32±15.94), in fifties (64.40±7.08) and in sixties (79.26±6.29). This showed the age group of sixties are 42.14% higher than the age group of thirties(p<.0l). 3. The percentage of VO₂peak was in thirties(78.57±5.42%), in forties(88.64±7.34%), in fifties(90.47±6.17%) and in sixties(94.10±6.37%). This showed no meaningful difference like 40>30(p<.05), 50>30(p<.0l), 60>30(p<.001). 4. The percentage of average heart rate was in thirties(69.28±3.68%), in forties (72.79±5.54%), in fifties(67.05±6.86%), and in sixties(72.84±5.38%). It showed no meaningful difference between age groups. 5. The percentage of peak heart rate was in thirties(86.31±5.91%), in forties(89.14±5.21%), in fifties(86.46±7.49) and in sixties(88.13±6.87), it also didn't show a meaningful difference. Consequently, Kilo calorie when performing Basic Gymnastics of New Millenium Health Work Out was similar to when performing light jogging. All the age groups showed moderate exercise intensity in average exercise intensity but age groups of forites, fifties and sixties except thirties showed more than a hard exercise intensity when they reached the level of peak exercise intensity

탄성밴드 운동이 뇌졸중 편마비 장애인의 하지근력, 평형성 및 보행능력에 미치는 영향
안선향 ( Seon Hyang Ahn ),이정필 ( Jeong Pil Lee ),윤진호 ( Jin Ho Yoon ),김상훈 ( Sang Hoon Kim ),오재근 ( Jea Keun Oh ) 한국특수체육학회 2009 한국특수체육학회지 Vol.17 No.4
본 연구는 초발한 뇌졸중 편마비 장애인을 대상으로 총 6주간의 입원기간 중 절대안정이 요구되는 초기 1주일을 제외한 5주간의 입원 기간 중에 탄성밴드를 이용한 운동 프로그램을 실시하여 하지근력, 평형성 및 보행능력에 미치는 영향을 살펴보기 위해 시도하였다. 이를 위해 뇌졸중 편마비 여성 장애인 14명을 물리치료만 실시한 비교집단과 물리치료와 탄성밴드 운동을 병행한 운동집단으로 각각 7명씩 무선배정하고 이들과 신체적 특성이 유사한 정상인 여성 7명을 일반집단으로 선정하였다. 탄성밴드 운동은 주 6회의 빈도로 5주간 실시하였으며 분석결과 다음과 같은 결과를 얻었다. 물리치료와 탄성밴드 운동을 병행한 운동집단이 물리치료만 실시한 비교집단에 비해 하지근력이 더 많이 개선된 것으로 나타났으며 평형성도 환측과 건측 모두 비교집단에 비해 유의하게 향상된 것으로 나타났다. 보행능력을 측정하기 위한 항목에서는 6m 걷기속도, 분속수 및 보폭의 기록이 향상된 것으로 나타났다. 이상의 결과를 종합하면 본 연구에서 초발 후 입원 기간 중에 실시한 5주간의 탄성밴드 운동이 뇌졸중 편마비 장애인의 하지근력과 평형성을 향상시켰으며, 보행능력도 개선시키는 효과가 있는 것으로 나타났다. The purpose of this study was to investigate the effects of the 5-week Elastic-band exercise on the strength of lower extremities, balance and gait ability in hemiplegia. For this study, fourteen female patients with hemiplegia caused by strokes were participated voluntarily and then there were divided into two groups; i) Control group(n=7, physical therapy), ii) Exercise group(n=7, physical therapy and elastic-band exercise). Seven normal women were participated as a Normal group. Elastic-band exercise were accomplished during 5weeks(6days/week). All tests were completed before and after experiment. The results of this study were as follows; Strength of lower extremities were higher in exercise group compared to control group. Balance test of exercise group was significantly improved in post test compared to pre test. Also 6m walking velocity, cadence, and step length were significantly improved in exercise group compared to control group. As a results, the elastic-band exercise can improve strength of lower extremities, balance and gait ability in hemiplegia.
