The purpose of this study was to evaluate the results of analysis of covariance (ANCOVA) with ages that can be controlled through this study, taking into account the fact that adult males can bring a direct impact on the body mass index (BMI) level and blood pressure, and physical fitness. The subjects of this study was 243 adult males, who has no case past history, and BMI groups were divided in three groups (normal, 18.5~22.9 kg/㎡; over weight, 23~24.9 kg/㎡; and obesity, over 25 kg /㎡). The results were analyzed statistically using ANCOVA, and Bonferroni test was used in the event of a significant F-ratio (p<.05). Systolic blood pressure (SBP) and diastolic blood pressure (DBP) in the obesity group was significantly higher than the normal group, respectively (p<.05).VO₂max in the obesity group was significantly lower than the normal and overweight groups, respectively (p<.05). Isokinetic thigh muscle strength in the normal group was significantly higher than obesity group at three variables (knee flexion left, KFL; knee extension right, KER; knee extension left KEL), respectively (all, p<.05). The results of the push-ups, in the obesity group was significantly lower than the normal group (p<.05). Ages that can be controlled through the analysis of covariance, taking into account the results of this study in accordance with the increase of age, the BMI affects respectively.

The purpose of this study to explore and conclude relationships between body mass index (MBI) level and blood pressure, VO₂max and isokinetic strength. The subjects chosen for the study were sample size of 211 middle-aged women divided into three groups(normal, 18.5~22.9 ㎏/㎡; overweight, 23~24.9㎏/㎡; obese, over 25㎏/㎡) according to their BMI level. The data was analyzed by analysis of covariance(ANCOVA) with age as the covariate via SPSS 18.0 soft program. One-way ANOVA was used because the relationship between age and BMI cannot be established. Bonferroni test was performed as post-hoc analysis to obtain the results hereafter with significance level set at α=.05. First, the obese group showed higher systolic blood pressure(SBP) and diastolic blood pressure(DBP) than that of the normal group, with significance(both p<.05). Also SBP was significantly higher in the overweight group than the normal group(p<.05). Second, the obese group’s VO₂max was lower than those of the overweight and normal group, with significance(both p<.05). Lastly, isokinetic strength in the normal group was significantly higher than the obese group in four variables(Knee flexion right, KFR; knee flexion left, KFL; knee extension right, KER; knee extension left, KEL) (in which of all p<.05) while KER and KEL was significantly higher in overweight group than in the obese group(both p<.05). Therefore it can be concluded that BMI level has influence on blood pressure, VO₂max, and isokinetic strength, calling for more awareness on the importance of middle-aged women’s weight control. Also the results can possibly serve for studying and developing activities that consider middle-aged women’s shape and physical.

Obesity is being regarded as a disease which causes the most serious public health problem in single disease. It also has a big impact on mortality directly and indirectly. The purpose of this study was to investigate the effects of low intensity walking for 12 weeks on body composition, physical strength, blood content and nutrition uptakes in obese women. The subjects of this study were 17 women in middle ages, who has no case past history, and their percent body fat was over 35%. For data analysis, mean and standard deviation scores were indicated, and paired t-test was used at p<0.05. After aerobic exercise for 12 weeks, body composition, physical strength and blood contents showed significant differences compared with pre and post respectively. This data suggest that low intensity walking exercise for 12 weeks have any beneficial effects in a major mechanism of physiological variation and obese reduction.

It was suggested that the exercise pressor reflex(EPR) plays an important role in the cardiovascular responses to exercise intensity. EPR experiment function was altered and exaggerated cardiovascular response during resting in obese people. But it was not reported that the exaggerated cardiovascular responses to exercise are mediated by EPR overactivity in exercise intensity with obese people. Therefore, this study was to compare the physiological responses between non-obese and obese middle aged women in exercise intensity. 14 non-obese subjects and 25 obese subjects with percent body fat were recruited for this study. All subjects were continuously instrumented to measure stroke volume, heart rate, cardiac output, total vascular conductance, and blood pressure with increasing workloads(40%, 60% of VO_2max). The results showed that systolic blood pressure, diastolic blood pressure, and mean arterial pressure significantly increased in both groups with increasing workloads that those blood pressure were significantly higher in subjects with obese middle aged women. There were no differences in stroke volume(SV) between both groups with increasing exercise intensity. Cardiac output(CO), and total peripheral resistance(TPR) was significantly higher in subjects with obese middle aged women at 60% of VO_2max. This study suggests that there were an exercise blood pressure responses in people with obese middle aged women of essential blood pressure in exercise intensity and there may be higher risk of future hypertension development.

It is generally known that in hypertensive individuals, exercise induces exaggerated increase in arterial blood pressure and in turn this dangerous elevation may increase the risks for myocardial infarction, cardiac arrest, or stroke. However, it has still not been investigated whether the exaggerated cardiovascular responses occur in prehypertension and these excessive responses are mediated by exercise pressor reflex overactivity. Therefore, the purpose of this study was to examine the effects of exercise pressor reflex on the cardiovascular responses when exercise intensity increased from rest through low exercise intensity to high exercise intensity. Twenty young, fit people (10 normotension and 10 prehypertension) with normal body fat percentage were recruited for this study. All subjects were instrumented to measure the cardiovascular responses at rest and during exercise. A catheter to collect blood samples was inserted into left brachial vein. Systolic blood pressure, diastolic blood pressure, and mean arterial blood pressure were significantly higher in prehypertension across workloads compared to the normotension. Stroke volume (SV), heart rate (HR), and cardiac output (CO) were significantly increased in both groups with increasing workloads, but SV and CO were significantly higher in prehypertension. There was no difference in total vascular conductance in both groups. Thus, exaggerated blood pressure responses were mediated via increases in CO. This study suggests that the excessive cardiovascular responses to exercise in prehypertension may be due to dysfunction of exercise pressor reflex.

We investigated the accuracy of a activity tracker, a wrist-worn device and a waist-worn device that estimate energy expenditure. 100 subjects aged from 20 to 39 yrs engaged in simulation of physical activity, walking and running on a treadmill. For validity, a portable metabolic cart was used as criterion measure. Comparability was tested by wearing of both wrist and waist accelerometers during each 30 min simulation of daily activity, walking and running. The energy expenditure obtained from the wrist-worn accelerometer was highly correlated with those from the portable metabolic cart. Significant and positive correlations were found to be 0.4 and 0.8 (p<0.05), respectively during simulation of daily activity, and walking and running. Significant and positive correlations between waist-worn and the portable metabolic cart were found to be 0.6 and 0.8 (p<0.05), respectively during simulation of daily activity, and walking and running, These data suggest that a multi-sensor accelerometer is a valid device for monitoring energy expenditure during physical exercise and activities of daily living. This device is easier to wear and may facilitate long-term recordings.

The purpose of this study was to evaluate energy expenditure of active video dancing game and to determine the effects of dancing game on growth hormone and serotonin. 10 men(mean age=32.6±2.0) and 10 women(mean age=32.3±2.1) completed three aerobic exercise session in which they performed active video dancing game(6min), walking(6km/h, 6min), and Jogging(8km/h, 6min). There was 30-min rest intervals between dancing game and walking, and 10-min rest intervals between walking and Jogging. Energy expenditure data was collected by the Cosmed K4b2, which was averaged over a 20-s period. Blood hormones were sampled and analyzed before and after exercise. The results were analyzed statistically using repeated one-way ANOVA, and Tukey HSD test was used in the event of a significant F-ratio(p<.05). The energy expenditure of active video dancing game was significantly increased by 467% compare to rest(p<.05). It was similar to that of 6km walking. The plasma concentration of growth hormone was increased about 77% after dancing game, but no significant difference was observed between before and after. The plasma concentration of serotonin was significantly increased about 27% after dancing video game(p<.05). These findings indicate that active video dancing game may be an effective aerobic exercise for those who have no time doing work out in facilities and like to do physical activity like dance.

From March-25, 2000 to April-2, 2000, we investigated anthropometry, body composition, and general lifestyle of 157 collegiate students in Kyung-Gi province and 106 soldiers of the Korean Army Soldiers in Kang-Won province. The results were as follows : 1.There was no significant difference of the height between the students and the soldiers. The Weight of the students was 64.9±7.8kg compared to 69.3±7.1kg of the weight of the Army soldiers. The percent body fat was 17.0±4.1% and 14.8±3.2% for the students and the sold-iers, respectively. 2.The trend of height is that the most highest population is the under fat groups, with the students 173.8±5.9cm and the soldiers 173.6±6.0cm. The population with obese groups had the lowest height. 3.TBW of the soldiers was 40.9±4.2ℓ, which is about 3.7 ℓ more than TBW of the students. And the soldiers had more protein and mineral of body, about 1.4kg and 0.14kg. respectively. 4.In students, the obese group had the most TBW, 38.0±2.8ℓ. In sold-iers, the under fat soldiers, however, had the most TBW, 41.2±4.2ℓ. 5.The percents of people with the iregular lifestyle were 79% and 17%, the students and soldiers, respectively, and the percent of people drinking three times per week were 29% and 3%, the students and soldiers, respectively. 6.51% in the students and 75% in the soldiers were smokers, and 64% in the students and 85% in the soldiers considered them healthy. 7.65% in the students and 7% in the soldiers have taken an irregular meal and 50% and 15% often had instant food. 8.25% in the students and 100% in the soldiers take an regular exercise, and frequency is 3 times per week and 5 times per week, students and soldiers respectively. 9.In collegiate students, Pearson coefficient correlation between height and weight was proportional with r=0.320, between height and LBM with r=0.565, and also weight and WHR with r=0.490, weight and LBM with r=0.900, weight and percent body fat with r=0.559, WHR and LBM with r=0.311, percent body fat and WHR with r=0.515, smoking amount and lifestyle with r=0.277, smoking amount and frequency of drinking with r=0.370, but height and percent body fat had inverse proportion with r=-0.342. 10.In Amy soldiers, Pearson coefficient correlation between height and weight was proportional with r=0.675, and also between height and LBM with r=0.744, weight and WHR with r=0.298, weight and LBM with r= 0.932, percent body fat and WHR with r=0.284. But Pearson coefficient correlation between percent body fat and smoking amount had inverse proportion with r=-0.240.
