The purpose of this study was to investigate the effects of low-intensity cardiac rehabilitation exercise on the cardiac function and the degree of fibrosis in an older white rat model. This study used male Sprague-Dawley white rats that were 50 weeks old. After the acute myocardial infarction induction, Twenty of the rats were randomly allocated into an experimental group and a control group, and each of the groups consisted of 8 rats. In the experimental group, the exercise was conducted for six weeks, 30 minutes a day, five days a week, using a Rotarod treadmill for animals. The degree of myocardial fibrosis was significantly repressed in the experimental group($13.69{\pm}1.90%$) and in the control group($15.67{\pm}1.54%$)(p<0.05). However, fractional shortening and ejection fraction did not show a significant difference. The results of this study suggest that cardiac rehabilitation with low intensity treadmill exercise repress the myocardial fibrosis.

The purpose of this study was to investigate the degree of improvement of scoliosis, muscle function and VAS between the exercise group and the control group after conducting correct posture exercise program with 20 female students diagnosed with scoliosis through PAPS in M middle school for 12 weeks. The conclusion was as follows. Cobb's angle in exercise group was changed from $11.6^{\circ}{\ae}2.5^{\circ}\acute{y} $ to $7.3^{\circ}{\ae}2.0^{\circ}\acute{y} $ which was statistically significant difference (p<.001). However, the change in Cobb's angle was not significant in control group, hence there was no statistically significant difference. The limber back strength was changed from $45.9^{\circ}{\ae}8.7$ kg to $51.6^{\circ}{\ae}14.9$ kg and sit-up was changed from $13.7^{\circ}{\ae}5.1$ times to $12.9^{\circ}{\ae}5.3$ times in exercise group, but they were not statistically significant. Control group also showed no statistically significant change in back strength and sit-up. The degree of VAS was changed from $7.3^{\circ}{\ae}1.6$ to $3.3^{\circ}{\ae}2.4$ which was a statistically significant difference (p<.01) in exercise group. However, there was no statistically significant difference in control group. Consequently, correct posture exercise program was considered to be effective for the reduction of Cobb's angle and degree of VAS for middle school female students with scoliosis. Therefore the correct posture exercise program can be recommended for youth scoliosis to improve and prevent the body imbalance and ultimately for the health of the youths.

The purpose of this study was to analyze the effect of acute forest walking exercise on blood glucose of IGT (impaired glucose tolerance), NIDDM (non-insulin dependent diabetes mellitus) in the elderly. There were four groups (n=60): forest walking exercise with IGT group (n=15; $66.21{\pm}4.16$ yrs), forest walking exercise with NIDDM group (n=15; $64.85{\pm}3.23$ yrs), field walking exercise with IGT group (n=15; $67.44{\pm}1.78$ yrs), field walking exercise with NIDDM group (n=15; $65.55{\pm}8.21$ yrs). They were tested on blood glucose levels at the beginning and at the end of each walking exercise. While the forest walking groups (interval + resistance exercise) worked for 40minutes with HRmax 50~60% level, the field walking groups (only aerobic exercise) worked for 40 minutes with HRmax 50~60% level. For data analysis, mean and standard deviation scores were calculated, and paired t-test and ANCOVA test were used. This study resulted in as follows. First, both walking groups showed the significant decrease of blood glucose in impaired glucose tolerance (IGT) after completing each exercise. Second, while the forest walking group showed the significant decrease of blood glucose in insulin dependent diabetes mellitus (NIDDM) after completing the forest exercise, the field walking group did not present any decrease of blood glucose in NIDDM after the field walking exercise. Therefore, the present findings suggest that the forest walking exercise as an interval and resistance exercise may be more effective to decrease blood glucose for IGT and NIDDM peoples in comparison to the field walking exercise as an aerobic exercise.

Adiponectin and Gut hormones(insulin, glucagon, ghrelin, PYY and GLP-1) are recently discovered peptides that are associated with lipid metabolism, insulin resistance, and control appetite. The purpose of this study was to investigate the effects of acute treadmill exercise(walking, 45min ; all-out running, 5min) on Adiponectin and gut hormones in high school ssireum player(light class, n=8; heavy class, n=8). From the experimental results, Adiponectin and ghrelin of light class were significantly higher than heavy class(p<.05), but there was no difference between pre and post exercise. Insulin level of heavy class was significantly higher than that of light class(p<.01) and no difference between pre and post exercise. Only glucagon significantly increased after exercise(p<.01), but no difference between classes. PYY and GLP-1 were no difference on classes and pre vs. post-exercise. The result of this study suggest that adiponectin, ghrelin and insulin were affected by body weight(light class vs. heavy class) and glucagon was affected by acute exercise.

The purpose of this study was to examine the effects of acute aerobic exercise at different intensities on the blood pressure, blood lipids and fibrinolytic markers in pre-hypertension college-aged males. Six subjects performed an acute running exercise at three different intensities(low intensity(LI): 50-60% heart rate reserve(HRR), moderate intensity(MI): 60-70%HRR, and high intensity(HI): 70-80%HRR). The blood pressure(systolic(SBP) and diastolic blood pressure(DBP), blood lipids(total cholesterol(TC) and high-density lipoprotein cholesterol(HDL-C)) and fibrinolytic markers(tissue plasminogen activator(tPA) and plasminogen activator inhibitor-1(PAI-1)) were determined before(PRE), immediately after(POST) and 60minutes after the exercise(60 POST). Results: the SBP in the LI group was significantly increased at POST(p=0.013). The ES levels for the SBP in the MI and HI groups were reduced (-1.33 and -1.23, respectively), though the differences were not significant. The HDL in the MI(p=0.003) and HI(p=0.002) groups were significantly increased at 60 POST. Also, the tPA in the MI(p=0.021) and HI(p=0.042) groups were significantly increased at POST.

[Purpose] Strenuous exercise often induces skeletal muscle damage, which results in impaired performance. Sphingolipid metabolism contributes to various cellular processes, including apoptosis, stress response, and inflammation. However, the relationship between exercise-induced muscle damage and ceramide (a key component of sphingolipid metabolism), is rarely studied. The present study aimed to explore the regulatory role of sphingolipid metabolism in exercise-induced muscle damage. [Methods] Mice were subjected to strenuous exercise by treadmill running with gradual increase in intensity. The blood and gastrocnemius muscles (white and red portion) were collected immediately after and 24 h post exercise. For 3 days, imipramine was intraperitoneally injected 1 h prior to treadmill running. [Results] Interleukin 6 (IL-6) and serum creatine kinase (CK) levels were enhanced immediately after and 24 h post exercise (relative to those of resting), respectively. Acidic sphingomyelinase (A-SMase) protein expression in gastrocnemius muscles was significantly augmented by exercise, unlike, serine palmitoyltransferase-1 (SPT-1) and neutral sphingomyelinase (N-SMase) expressions. Furthermore, imipramine (a selective A-SMase inhibitor) treatment reduced the exercise-induced CK and IL-6 elevations, along with a decrease in cleaved caspase-3 (Cas-3) of gastrocnemius muscles. [Conclusion] We found the crucial role of A-SMase in exercise-induced muscle damage.

The purpose of this study was to survey the effects of Karvonen exercise prescription in coronary artery disease patients reaching age-predicted maximal heart rates with the exercise stress test on hemodynamic responses and cardiorespiratory fitness. The subject group was comprised of acute coronary syndrome (ACS) patients, who were divided into the maximal heart rate (MHR) group that included those who completed the test with their heart rates reaching the number of 220-age and the maximal dyspnea (MD) group that included those who could not continue the test due to respiratory difficulty and were asked to stop the test. Both groups had the exercise stress test before and after the experiment. In the exercise stress test before the experiment, the exercise prescription intensity of Karvonen was set at the target heart rates of 50~85% with a six-week exercise monitoring arrangement. As a result, there were no interactive effects in rest heart rate (RHR) according to time and group, but interactive effects were observed in maximal heart rate (MHR) (P=0.000). Both rest systolic blood pressure (RSBP) and rest diastolic blood pressure (RDBP) had no interactive effects according to time and group. Maximal systolic blood pressure (MSBP) showed significant interactive effects according to time and group (P=0.017). Maximal diastolic blood pressure (MDBP) showed no interactive effects according to time and group, while maximal rate pressure product (MRPP) showed significant interactive effects according to time and group (P=0.003). Maximal time (MT) had no interactive effects according to time and group. $VO_{2max}$ and maximal metabolic equivalent (MMET) showed significant interactive effects according to time and group (P=0.000, P=0.002, respectively), whereas maximal respiratory exchange ratio (MRER) and maximal rating of perceived exertion (MRPE) showed no interactive effects according to time and group. The exercise test that was discontinued as the subjects reached the predicted maximal heart rates considering age did not reach the maximal exercise intensity and accordingly showed low exercise effects when applied to Karvonen exercise prescription intensity. That is, the test should keep going by monitoring cardiac events, MRER and MRPE until the heart rates exceed the predicted MHR by up to 10~12 even after the subject reaches the predicted MHR considering age in the exercise stress test.

The purpose of this experiment was to examine influence of acute exercise on nocturnal sleep which had been disrupted by caffeine(400mg$\times$3) thought the daytime. Six healthy young males aged 21.0$\times$0.2 yr with a history of low caffeine use. Subjects completed three conditions in a within-subject. At three conditions Sleep EEG were investigated: (1) nocturnal following quiet rest, (2) nocturnal sleep following the consumption of 1200mg of caffeine (3) nocturnal sleep following cycling at 60 min of 60% V $O_{2peak}$ with 1200mg of caffeine consumption. Sleep data were calculated for REM sleep, REM latency, sleep onset latency, sleep efficiency, sleep stages, SWS. Those data were analyzed using repeated-measures ANOVA of change scores. A main effect to, drug(caffeine) indicated that caffeine elicited sleep disturbance that is, TST and sleep onset latency increase and sleep efficiency and stage 4 decrease. The effects of exercise on sleep following caffeine intake generally improve sleep that is, stage 2, 3 and SWS increase and sleep onset latency decrease. A condition effect for sleep indicated sleep improvement after exercise Therefore The data supported a restorative theory of slow-wave sleep and suggest that acute exercise may be useful in promoting sleep and reducing sleep disturbance elevated by a high dose of caffeine.
