BACKGROUND/OBJECTIVES: Energy production and the rebuilding and repair of muscle tissue by physical activity require folate and vitamin $B_{12}$ as a cofactor. Thus, this study investigated the effects of regular moderate exercise training and durations of acute aerobic exercise on plasma folate and vitamin $B_{12}$ concentrations in moderate exercise trained rats. MATERIALS/METHODS: Fifty rats underwent non-exercise training (NT, n = 25) and regular exercise training (ET, n = 25) for 5 weeks. The ET group performed moderate exercise on a treadmill for 30 min/day, 5 days/week. At the end of week 5, each group was subdivided into 4 groups: non-exercise and 3 exercise groups. The non-exercise group (E0) was sacrificed without exercising and the 3 exercise groups were sacrificed immediately after exercising on a treadmill for 0.5 h (E0.5), 1 h (E1), and 2 h (E2). Blood samples were collected and plasma folate and vitamin $B_{12}$ were analyzed. RESULTS: After exercise training, plasma folate level was significantly lower and vitamin $B_{12}$ concentration was significantly higher in the ET group compared with the NT group (P < 0.05). No significant associations were observed between plasma folate and vitamin $B_{12}$ concentrations. In both the NT and ET groups, plasma folate and vitamin $B_{12}$ were not significantly changed by increasing duration of aerobic exercise. Plasma folate concentration of E0.5 was significantly lower in the ET group compared with that in the NT group. Significantly higher vitamin $B_{12}$ concentrations were observed in the E0 and E0.5 groups of the ET group compared to those of the NT group. CONCLUSION: Regular moderate exercise training decreased plasma folate and increased plasma vitamin $B_{12}$ levels. However, no significant changes in plasma folate and vitamin $B_{12}$ concentrations were observed by increasing duration of acute aerobic exercise.

[Purpose] The effect of acute nitrate supplementation on muscle fatigue is largely unknown. This study aimed to evaluate the effect of acute nitrate supplementation on muscle fatigue. [Methods] Thirty-five recreationally active subjects consumed 140 ml of beetroot (BR) juice (nitrate: 8 mmol·d^-1) or placebo (PL) 12 and 2.5 hours before two exercise sessions. Peak torque was measured during 50 repetitions, at maximal effort, and during concentric knee extensions at 90°·s^-1. Blood pressure (BP) was recorded pre- and post-exercise. [Results] Peak torque, maximum work, rate of fatigue, and rate of work fatigue were similar between the BR and PL conditions. Post-exercise diastolic BP (BR: 67.2 ± 9.8 vs. PL: 64.5 ± 7.9 mmHg, p < 0.05) and mean arterial pressure (BR: 91.6 ± 9.3 vs. PL: 88.8 ± 8.2 mmHg, p < 0.05) were higher with BR supplementation. [Conclusion] These findings suggest that the acute intake of BR juice had no effect on knee extensor muscle strength or fatigue but increased BP in a healthy recreationally active population.

Purpose: This study compared the effectiveness of sling exercise and McKenzie exercise in patients with acute cervical whiplash associated disorder (WAD) caused by rear-end collision. Methods: Thirty WAD patients were randomly assigned to one of three groups; a sling exercise (SE) group, a McKenzie exercise (McE) group, and a control group. Members of the SE and McE exercised three times a week for four weeks under the researcher's guidance. Three groups performed TENS treatment three times a week for four weeks. Diagnostic radiological equipment was used to measure whiplash injury. Visual analog scale (VAS), neck disability index (NDI), and range of motion (ROM) were used in this study. Results: The three groups showed a significant pre-post treatment difference in measures of VAS and NDI (p<0.05). The SE group showed a significant pre-post treatment difference in measures of flexion and extension changes compared to the McE and control group (p<0.05). The SE group also showed significantly greater improvement in the VAS, NDI, and ROM changes than the control group (p<0.05). Conclusion: These findings indicate that sling exercise is a stronger and more aggressive intervention for treatment of acute WAD patients.

The purpose of the study was to investigate effects of Low intensity cardiac rehabilitation, using a treadmill, on the myocardial structure. We identified the effects by analyzing changes in the rats' weights and the results of biopsies. Twenty Sprague-Dawley male rats, 50 weeks old, were randomly divided into the exercise group and the control group. myocardial infarction(MI) was induced by ligaturing their left anterior descending artery. After the acute MI induction, two rats of each group began to fall dead, therefore, eight of each group completed at the end of the experiment. We used treadmills for animals for the exercise group. This exercise group performed 30 minutes of exercise five times per week for six weeks, while the control group did not perform any exercise. No statistically significant differences in weight were found in within group comparison and between group comparison. Furthermore, we observed histological changes in the myocardium using Hematoxylin & Eosin and Masson's trichrome staining in both groups. Low-intensity exercise inhibited myocardial fibrosis, may serve as a reference in the cardiopulmonary field, which plays a role in rehabilitating patients with cardiac disorders, including acute MI.

Purpose : The purpose of this study was to investigate effects of movement with mobilization(MWM) and stabilization exercise on pain and range of motion of patients with acute low back pain. Methods : The subjects were consisted of 24 patients who had non specific acute low back pain. All subjects randomly assigned to the MWM group and the stabilization exercise group. The MWM group received sustained natural apophyseal glides(SNAGs) with modality treatment and stabilization exercise group received stabilization exercise with modality treatment. The remodified schober test(RST) was used to measure forward flexion and lateral flexion range of motion of lumbar segment. Visual Analogue Scale(VAS) was used to measure subjective pain level of the patients. The Oswestry Low Back Pain Disability Scale was used to measure functional disability level of the patients. Results : The lumbar flexion range of motion of MWM group was significantly increased compared with stabilization exercise group(p<.01). The range of motion of lumbar segment of MWM group was significantly decreased compared with stabilization exercise group(p<.01). The left lateral flexion range of motion of lumbar of MWM group was significantly decreased compared with stabilization exercise group(p<.05). The right lateral flexion range of motion of lumbar of MWM group was significantly decreased compared with stabilization exercise group(p<.05). The VAS of both MWM group and stabilization exercise group was significantly decreased(p<.001). The Oswestry Low Back Pain Disability Scale of stabilization exercise group was significantly increased compared with mobilization group(p<.001). Conclusion : In the result of this study, mobilization with movement and stabilization exercise had significant difference on pain and flexibility of patients with acute low back pain.

Physical activity is a primary cancer control strategy that has received little attention to date. However, an Increasing number of epidemiological studies have proposed that physical exercise may be beneficial by enhancing anticancer immune system responses. We investigated the effects of acute exercise on changes in nitric oxide (NO) production and inducible nitric oxide synthase (iNOS) expression. The amounts of NO generated by abdominal macrophages in mice were measured after exercise. Thirty-two mice, which were challenged with thioglycollate broth to activate peritoneal macrophages, were randomly assigned to control, exercise and recovery groups. The mice exercised on a motor-driven treadmill for 3 consecutive days, either moderately (18m/min, 30 min/day, 5％ grade) or severely (18-35m/min, 60 min/day, 5％ grade). The mice were killed immediately after exercise or after 6 hrs of recovery. Nitric oxide was quantified by the Griess assay. The exercised mice showed higher levels of NO generation than those of the control mice, but the intensity of exercise had no significant effect on NO generation. Mice allowed six hours of recovery after exercise showed higher levels of NO generation than that of animals sacrificed immediately after exercise, but there were no significant differences in NO generation with variations in the intensity of exercise. Increased levels of iNOS were found in the exercised groups, and this was greatest in the groups allowed six hours of recovery compared to those groups sacrificed immediately after exercise. The results of this study suggest that acute exercise may enhance an immune response by inducing macrophage-derived NO generation; these results support the epidemiological findings which support the benefits of exercise in the prevention and control of cancer. Further study is needed to determine the physiological significance of these findings, which could be applied to the use of therapeutic exercises to assist in the prevention and control of cancer.

Purpose: This study aimed to identify the effects of a task-oriented exercise program on balance in patients with acute stroke. Methods: Twenty participants with hemiparesis resulting from acute stroke volunteered to participate in this study. They were randomly assigned to either the experimental or control group, with 10 patients per group. Both groups underwent a task-oriented exercise program averaging 30 minutes daily for 4 weeks. Balance was assessed before and after the 4-week training period. Before and after the intervention, we conducted a paired t-test to compare the within-group changes and an independent t-test to compare the between-group differences. The statistical significance level was set at p=0.05 for all the variables. Results: Both groups showed significant within-group and between-group changes in balance (p<0.05) after the intervention. Conclusion: This study provides valuable information for future studies in this field. Further research using a larger sample and longer experiment spans can corroborate the results of our study.

The purpose of this study was to investigate the effects of a acute ankle mobility exercise (AE) program on the range of motion and pain levels associated with chronic ankle instability (CAI). Twenty adult women with an average score of 24 or less on both sides in the ankle instability questionnaire were selected and divided into two groups: the Ankle Mobility Exercise Program group (AE, n=10) and the control group (CON, n=10). The AE treatment involved a one-time, 20-minute exercise session for each ankle, conducted separately on the left and right ankles, to examine the response to a acute exercise. Measures of ankle instability, pain, and ankle range of motion were evaluated before and after the treatment. In the AE group, which underwent the AE program, a significant decrease in pain was observed post-AE compared to pre-AE (p<.01). In addition, an increase in dorsiflexion was observed in the AE group post-AE compared to pre-AE following the AE program(p<.05). These results suggest that a acute AE program can effectively alleviate some aspects of ankle instability by improving ankle pain and range of motion in adult women with chronic ankle instability (CAI).

Background: The purpose of this study was to investigate the effects of kinesio taping and neuromuscular rehabilitation exercise for patients with acute whiplash-associated disorders. Methods: Twenty acute whiplash-associated disorders patients were recruited for the study. Subjects were randomly allocated into two groups. Neuromuscular rehabilitation group (NRG) received neuromuscular rehabilitation exercise, kinesio taping group (KTG) received kinesio taping. All subject was evaluated before and after intervention by their range of motion (ROM), neck disability index (NDI), numeric pain rating scale (NPRS) and fatigability. Results: First, the ROM was significantly increased in all group (p<.05). The NDI, NPRS and fatigability were significantly decreased in all group (p<.05). Secondly, NRG had significantly more increased ROM (flexion, both rotation) than KTG (p<.05). NRG had significantly more decreased NDI, NPRS and fatigability than KTG (p<.05). Conclusion: According to the results above, increased in range of motion in the neck, decreased in NDI, NPRS, fatigability were more effective in the NRG that received neuromuscular rehabilitation exercise than the KTG that received kinesio taping.
