Background: This study conducted a comparative evaluation of the effects of Pilates stabilization exercise combined with pain neuroscience education (PNE) in patients with chronic low back pain. The evaluation was based on their visual analogue scale (VAS) scores, Korean Oswestry disability index (KODI) scores, and fear avoidance belief questionnaire (FABQ) scores. Methods: A total of 36 participants were recruited and randomly assigned to either a Pilates stabilization exercise group (PSE, n=18) or Pilates stabilization exercise combined with pain neuroscience education group (PPNE, n=18). Both the PSE and PPNE groups participated in 50-minute sessions of Pilates stabilization exercise, three times per week for six weeks. The VAS, KODI, and FABQ scores of the participants were measured before and after the intervention. Results: There were significant improvements in the VAS of the PSE and PPNE group, with significant difference found between them. Both groups showed a significant decline in KODI scores following the exercise interventions, with significant difference observed between the two groups. FABQ scores were significantly decline in both groups, with significant difference found between them. Conclusion: In this study, Pilates stabilization exercise combined with pain neuroscience education was found to be more effective than Pilates stabilization exercise alone in reducing the VAS, KODI, and FABQ scores of patients with chronic low back pain. Thus, Pilates stabilization exercise combined with pain neuroscience education can be used in clinical practice to treat and prevent chronic lower back pain.

The objective of this study was to investigate the effects of a nutritional education and physical exercise program on obese children (47 boys and 36 girls). The nutritional education and physical exercise program was provided for 6 weeks and dietary habits, nutrient intake and hematological profiles were measured before and after the program. The BMI (body mass index, $kg/m^2$) in male children was significantly reduced to $24.58{\pm}2.81$ from $25.89{\pm}3.27$ (p<0.01) and it was significantly reduced to $24.29{\pm}3.51$ from $25.21{\pm}3.59$ in female children after the completion of nutritional education and exercise program. Body fat in male children was remarkably reduced to $32.69{\pm}7.74%$ after education from $37.38{\pm}9.21%$ (p<0.001). After the program total cholesterol concentration in male children was reduced to $176.48{\pm}29.10\;mg/dL$ from $196.03{\pm}29.10\;mg/dL$, whereas there was no significant difference in females before and after the nutritional education and exercise program. The grasping power of male children (p<0.05) and backmuscle strength of male (p<0.05) and female children (p<0.001) were significantly increased after the exercise program. The nutrient intakes that were different before and after the nutrition education were calories (p<0.05) and carbohydrate (p<0.05) in male children, and a significant increase in intake of vitamin A (p<0.05) was found in female children. There was a significant difference in meal time regularity before and after program. The findings of this study showed that there was a significant decrease in both body fat and weight, in addition to normalization of hematological profiles after the completion of nutrition education and physical exercise programs.

This study assessed the amount of energy consumed and fat deposition after endurance training in order to review the effect of 4-week endurance exercise on resting metabolic rate of a mouse during and after exercise and the effect of exercise. A total of 19 seven-week-old ICR male mice were used as the study subject. Those mice were divided into sedentary group (Sed) and trained group (Tr) after a week of environment adaption. The Tr group was trained with endurance exercise five times a week for four weeks. Weight and the amount of food intake were daily weighed and resting metabolic rate and metabolic rate after exercise were assessed before starting exercise and on the fourth week after training. Metabolic rate during exercise were measured four weeks after training. At the end of breeding period, statistically significant difference was shown in weights of trained and sedentary groups (p < 0.05). During a resting period, no significant difference was shown in oxygen intake, respiratory exchange ratio, and the amount of carbohydrate and fat oxidized. Moreover, no significant difference was shown in excess post-exercise oxygen consumption (EPOC) of an hour period after training. In contrast, the maximal oxygen uptake (VO₂ max) was approximately 11.1% higher in trained group after training compare to before. However, there was no significant difference in respiratory exchange ratio and carbohydrate and fat oxidization. During exercise, oxygen uptake, carbon dioxide production, and respiratory exchange ratio in energy metabolism during exercise showed no significant difference. However, significant difference was exhibited in the amount of fat oxidized in both groups. Summing up those results, endurance exercise could be concluded to be effective in weight control. However, weight loss is thought to be resulted from increase in fat oxidization during exercise unlike the conclusion made from previous studies where weight loss is prominently influenced by energy metabolism during a resting period and increased fat oxidation during post-exercise recovery. All experimental procedures were carried out at the Animal Experiment Research Center of Konkuk University. This study was conducted in accordance with the ethical guidelines of the Konkuk University Institutional Animal Care and Use Committee.

[Purpose] Lactate is a principal energy substrate for the brain during exercise. A single bout of high-intensity interval exercise (HIIE) can increase the blood lactate level, brain lactate uptake, and executive function (EF). However, repeated HIIE can attenuate exercise-induced increases in lactate level and EF. The lactate levels in the brain and blood are reported to be correlated with exercise-enhanced EF. However, research is yet to explain the cause-and-effect relationship between lactate and EF. This study examined whether lactate consumption improves the attenuated exercise-enhanced EF caused by repeated HIIE. [Methods] Eleven healthy men performed two sets of HIIE, and after each set, 30 min were given for rest and examination. In the 2^nd set, the subjects consumed experimental beverages containing (n = 6) and not containing (n = 5) lactate. Blood, cardiovascular, and psychological variables were measured, and EF was evaluated by the computerized color-word Stroop test. [Results] The lactate group had a higher EF (P < 0.05) and tended to have a higher blood lactate level (P = 0.082) than the control group in the 2^nd set of HIIE. Moreover, blood lactate concentration was correlated with the interference score (i.e., reverse score of EF) (r = -0.394; P < 0.05). [Conclusion] Our results suggest that the attenuated exercise-enhanced EF after repeated HIIE can be improved through lactate consumption. However, the role of lactate needs to be elucidated in future studies, as it can be used for improving athletes' performance and also in cognitive decline-related clinical studies.

Objective: This study was performed to identify the related factors of exercise injury throughout the actual cases among patients. Method: The subjects of the study consisted of 304 patients(209 male and 95 female) over 20's in seoul and kyonggi area, and data collected by using questionnaires were analyzed with SPSS/WIN 11.0 program. To prove the relative factors of exercise injury from hospital patients Results: 1) It was found that the general degree of exercise injury showed significant difference regarding gender, age and education level. In other words, if it was male, young and high school graduate, the portion of exercise injury for the person was higher than others. On the other hand, the duration of medical treatment for the patient, who is male, old and college graduate took longer than the others. 2) It demonstrated that the lower extremity was most intensively damaged due to the exercise injury, especially, knees and ankles had the most portion of exercise injury and a sprain was the most common form of exercise injury for these body parts. 3) The degree of exercise injury regarding of exercise maintains significant difference with the frequency of exercise. In fact, the more exercise was done by a person such as 3 to 4 days a week, the less duration of medical treatment for the person was taken. 4) It also showed that there was significant difference between the habit of exercise and the degree of exercise injury. In other words, a person had better exercise habit, it took the person less duration of medical treatment. As well, if someone had better warming up, he or she had lower degree of exercise injury after all. Conclusion: Consequently, according to the data, the research suggested that the male needed more carefulness than the female in exercise. Old age people needed to be more careful of getting sprain of knee and ankle in particular. As well, it concluded that people needed not only enough warming up before doing exercise but also positive habit of exercise in order to minimize the exercise injury.

[Purpose] Exercise is a fundamental way to maintain and improve health and physical fitness. Many human studies have demonstrated the beneficial effects of exercise on various biological parameters. However, studies investigating the effects of exercise in dogs are limited. This review summarized the current data from studies that examined the effects of different exercise conditions (treadmill vs. non-treadmill and acute vs. chronic) on physiological and hematological parameters in dogs. [Methods] Papers addressing the effects of exercise in dogs published from January 2000 to October 2020 were retrieved from the online databases of Scopus, Google Scholar, and PubMed and were selected and reviewed. [Results] The exercise conditions differentially affected physiological and hematological responses and adaptation in dogs. Therefore, the development and comprehensive evaluation of scientific exercise programs for dogs are necessary. [Conclusion] The dog would be a valuable exercise science animal model, and studies aiming at the optimal health, well-being, and quality of life of dogs need to be conducted.
