The effects of regular endurance exercise, or acute-exercise and rest on the levels of lipids, carnitines and carnitine palmitoyltransferase-I (CPT-I) were investigated in male Sprague-Dawley rats. The rats were exercise trained on a treadmill for 60 min per day for 60 days (long-term trained, LT), or non-trained for 59 days (NT) and exercised for 60 min on the 60th day. In NT rats, the levels of serum nonesterified carnitine (NEC), acidsoluble acylcarnitine (ASAC), and total carnitine (TONE) increased significantly during the post-exercise recovery period (PERP). In LT rats, ASAC, and TCNE, which increased right after the 60 min running session decreased to the levels of pre-exercise during the PERP. The levels of skeletal muscle ASAC in NT rats, which increased significantly by the acute-exercise, decreased to the pre-exercise levels during the PERP. However, the ASAC level in LT rats reached its peak at 4 h after running for 60 min. Liver triglyceride (TG) and total lipids (TL), which increased by the acute-exercise, decreased to the pre-exercise levels during the PERP in both NT and LT rats. CPT-I activity in NT rats increased significantly after 1 h of a 60-min exercise and slowly decreased to pre-exercise levels during the PERP. However, the CPT-I activity in LT rats, which increased significantly by the 60 min exercise, decreased slowly and reached its pre-exercise level within 8 h of the PERP. Northern blot analysis showed that the changes of CPT-I activities during the PERP coincided with changes in CPT-I mRNA levels. This study shows that both regular endurance exercise, and acute-exercise and rest, can influence differently the levels of carnitines, lipids and CPT-I in rats. The results suggest that regular endurance exercise, rather than the acute-exercise, can change effectively the distributions of carnitines, lipids and CPT-I in rats during exercise and rest.

This study aimed to investigate the immediate physiological responses, including heart rate, blood pressure, and rate pressure product (RPP), following squat exercises performed at three water depths (ground, knee depth, waist depth) and two speed conditions (60bpm speed, Max speed). The participants consisted of 10 men in their 20s with over 6 months of resistance exercise experience. For the 60bpm speed squats, participants performed 30 repetitions in 1 minute at a rate of 2 seconds per repetition, while for Max speed squats, they performed at Max speed without a set limit on the number of repetitions for 1 minute. All experiments were conducted with a random assignment. The study results showed that immediately after the aquatic squat exercise, the average heart rate, blood pressure, and cardiac load were higher in the order of knee depth, ground level, and waist depth at both 60bpm speed and Max Speed. At 60bpm speed, the heart rate was higher in the order of ground level, knee depth, and waist depth. Overall, exercise in an aquatic environment was considered to impose relatively lower physical burden compared to land-based exercise. Therefore, it is suggested that depending on individual fitness levels and exercise goals, appropriately combining aquatic exercise, which imposes lower immediate physiological burden, and land-based exercise may lead to safer and more effective exercise methods.

Objectives: A great number of the elderly are not aware of having metabolic syndrome, and this pattern differs among regions of the nation. This issue is particularly important for the elderly people with chronic diseases. This study was conducted in order to identify the prevalence, predicting factors of perception and exercise behaviors of among the elderly population. Methods: Using data from the 2009 Korean Community Health Survey, we employed two-level logistic regression models to determine whether individual and community factors are associated with perception and exercise behaviors among the elderly population. Results: Results from weighted two-level logistic regression analyses indicated the individual-level factors of smoking, education level, health center education, community exercise program participation and unmet needs in men, and marital status (being separated), health center education women predicted the elders' perception. As for the community-level predictors, higher smoking and living in regions with high suicide rates significantly predicted the elders' perception and exercise behaviors of metabolic syndrome. Conclusions: These findings demonstrate that education according to stage would increase the perception and motivation toward healthier behavior particularly for the elderly with lower perception levels of metabolic syndrome.

The purpose of this study was to determine the independent and the combined effects of cell cultured Acanthopanax senticosus extracts (ASE) supplementation and swimming exercise on body weight, lipid profile, carnitine and leptin levels in C57 BL/6J mice. Forty C57BL/6J mice were divided into four groups: non-supplement and non-exercise (NSNE); non-supplement and exercise (NSE); supplement and non-exercise (SNE); supplement and exercise (SE) mice. They were allowed free access to food and water. The exercised groups were forced to swim (1hr, 6 days a week) in a water bath for 12 weeks. The supplemented groups were fed Cell cultured ASE (0.5 g/kg body weight/day) for 12 weeks. In this study, we found that the combination of Cell cultured ASE supplementation and exercise significantly decreased liver triglyceride (TG) level and serum leptin level but significantly increased serum HDL-cholesterol level compare to control (NSNE) group. These improved lipid profiles and decreased serum leptin would have positive effects on obesity and cardiovascular disease.

Background: It has been proved that participating in exercise improves colorectal cancer patients' prognosis. This study is to identify barriers to exercise in Korean colorectal cancer patients and survivors. Materials and Methods: A total of 427 colorectal cancer patients and survivors from different stages and medical status completed a self-administered questionnaire that surveyed their barriers to exercise and exercise participation. Results: The greatest perceived exercise barriers for the sampled population as a whole were fatigue, low level of physical fitness, and poor health. Those under 60-years old reported lack of time (p=0.008), whereas those over 60 reported low level of physical fitness (p=0.014) as greater exercise barriers than their counterparts. Women reported fatigue as a greater barrier than men (p<0.001). Those who were receiving treatment rated poor health (p=0.0005) and cancer-related factors as greater exercise barriers compared to those who were not receiving treatment. A multivariate model found that other demographic and medical status were not potential factors that may affect exercise participation. Further, for those who were not participating in physical activity, tendency to be physically inactive (p<0.001) and lack of exercise skill (p<0.001) were highly significant barriers, compared to those who were participating in physical activity. Also, for those who were not meeting ACSM guidelines, cancer-related exercise barriers were additionally reported (p<0.001), compared to those who were. Conclusions: Our study suggests that fatigue, low level of physical fitness, and poor health are most reported exercise barriers for Korean colorectal cancer survivors and there are differences in exercise barriers by age, sex, treatment status, and physical activity level. Therefore, support for cancer patients should be provided considering these variables to increase exercise participation.
