Purpose. The purpose of this study were to investigate the effects of a 12-week brisk walking program on triglycerides (TG) and apolipoprotein B (Apo B) and to compare these effects to those of a brisk walking plus diet program in middle-aged overweight/obese ($BMI{\geq}23$) Korean women with hypertriglyceridemia. Method. This analysis was done with nineteen middle-aged overweight/obese Korean women who completed either the brisk walking program (9 women) or the brisk walking plus diet program (10 women) for 12 weeks. The brisk walking consisted of walking for 20 to 50 minutes/day at an intensity of 40 to 70% of heart rate reserve (HRR) for 3 to 6 days/week. The diet consisted of 60 minutes of group education and 20 to 30 minutes of individual counseling every week. TG and Apo B were assessed pre- and post-intervention. Results. TG and Apo B decreased significantly after the brisk walking program (Z = -2.31, p = 0.021; Z = -2.59, p = 0.009). TG and Apo B lowering effects of the brisk walking program were not significantly different from those of the brisk walking plus diet program (U = 37.0, P = 0.549; U = 42.0, P = 0.842). Conclusion. Brisk walking can be an effective intervention for overweight/obese middle-aged women with hypertriglyceridemia in reducing cardiovascular risk by lowering TG and Apo B levels. Adding diet to brisk walking may have no additional significant effects on changes in TG and Apo B.

Background: Cervical radiculopathy is the result of cervical nerve root pathology that may lead to chronic pain and disability. Although manual therapy interventions including cervical traction and neural mobilization have been advocated to decrease pain and disability caused by cervical radiculopathy, their analgesic effect has been questioned due to the low quality of research evidence. The purpose of this paper is to present the effect of manual therapy on pain, ROM, disability in a patient experiencing cervical radiculopathy. Methods: In this study, 30 participants who met the diagnostic criteria for cervical radiculopathy were randomized into two groups: group I (nerve mobilization group) & group II (Mckenzie exercise group). The experimental group was performed manual cervical traction and neural mobilization technique. The control group was performed manual cervical traction and cervical retraction, extension exercise. Assessments were performed to 30 participants before and after 4 weeks therapy. The components of assessments were pain intensity (PI), cervical rotation ROM (CR) and neck disability index (NDI). Results: After 4 weeks therapy, PI, CR and NDI were significantly reduced in both groups (p<.01). The PI, CR and NDI were no significantly reduced between group I and group II (p>.01). Conclusions: Manual therapy could reduce the symptoms of cervical radiculotpathy.

Objectives: The purpose of this study is to identify prevalence and related factors of the elderly, who took health examination, with metabolic syndrome. Methods: The health examination and lifestyle survey were performed for 21,512 adults at 60 years of age or older who took health examination in H health promotion center during January-March 2009. Results: The prevalence of metabolic syndrome for the subject was 24.0%. Of the subject with metabolic syndrome, the prevalence of the diseases was obesity 60%, abdominal obesity 78.5%, hypertension 82.6%, dyslipidemia 89.7% and diabetes 51.9%. In comparison of the relationship between metabolic syndrome and other diseases, the male subject with metabolic syndrome were significantly higher in BMI, waist circumference, systolic/diastolic blood pressure, hemoglobin, AST, ALT, $\gamma$-GTP, TG, AC glucose, creatinine than normal male(p<0.001). In comparison of the relationship between metabolic syndrome and lifestyle, more drinking frequency and amount in male and more drinking frequency in female were associated with increased risk of metabolic syndrome(p<0.01). Regardless of exercise intensity, practice of exercise contributed to reduce the risk of metabolic syndrome(p<0.01). Conclusion: In conclusion, TLC program, focused on lifestyle behaviors which is strongly associated with the prevalence of metabolic syndrome, should be developed for the improvement of life quality in the elderly with metabolic syndrome.

Objective: The purpose of this study was to investigate the effects of an exercise with and without neuromuscular electrical stimulation (NMES) of the quadriceps femoris muscle, on strength, pain, and weight distribution in patients with knee instability post surgery. Design: Randomized controlled trial. Methods: Twenty patients in the early stage of rehabilitation after knee surgery were recruited as subjects and were randomly divided into either experimental group (exercise combined with NMES) (n=10) or control group (n=10). Both groups received strength training of the lower limb for 20 min/day, 5 days/week for 4 weeks. The experimental group used NMES for unilateral quadriceps femoris training with incremental increases in the intensity of isometric contraction over 4 weeks. Outcome measurements were assessed using the digital manual muscle testing, 30-chair stand test (30CST), numeric pain rating scale (NPRS) and weight distribution using the foot analyzer before and after 4 weeks of training. Results: After the 4-week intervention, knee extensor strength increased significantly in the experimental group post intervention (p<0.05), and there was a significant improvement in the experimental group compared with the control group (p<0.05). The 30CST and NPRS scores improved significantly in the experimental group compared to the control group (p<0.05), and there was a significant difference between the two groups (p<0.05). Weight distribution was significantly improved in the experimental group compared with the control group, (p<0.05), but there was no significant difference in improvement between the two groups. Conclusions: This study showed that NMES combined with strengthening exercises of the lower limbs is effective in improving lower limb pain and strength in patients with instability after knee surgery.

PURPOSE: To examine the cumulative (7 days) effect of breaking up prolonged sitting on systemic endothelial function in sedentary men. METHODS: Thirty sedentary men ($33.93{\pm}5.72years$) participated in two randomized 7 days sitting trial (Sit group (control) vs. Breaks group). The protocol of Breaks group is as follows: 4-minute of moderate-intensity marching in place (walking) every 1 hour during business hour (total: 8 breaks/day). Assessment of brachial artery endothelial function using flow-mediated dilation (FMD) and arterial stiffness indices (augmentation index, arterial pressure and pulse wave velocity) were measured before and after 7 days treatment. RESULTS: Brachial artery FMD significantly increased after 7 days breaking up prolonged sitting treatment (Breaks groups, $9.65{\pm}2.61$ to $9.62{\pm}2.6%$) compared with 7 days prolonged sitting (Sit group, $8.37{\pm}3.41$ to $10.11{\pm}3.75%$) (interaction effect, p=.004). Arterial pressure (AP) significantly increased after treatment (Breaks group, $2.75{\pm}2.19$ to $2.38{\pm}1.63mmHg$, p=.002) in Sit group but there was no change (Sit group, $1.00{\pm}3.18$ to $2.50{\pm}9.23mmHg$) in Breaks groups (interaction effect, p=.008). CONCLUSIONS: These finding show that 7 days regular breaking up prolonged sitting improve in FMD, compared with prolonged sitting. Therefore, regular breaking up prolonged sitting may improve systemic endothelial function in sedentary men.

The purpose of this study is to review the effect of previous research data with virtual reality-based Physical Activity Therapy Programs(PATPs) in adult on the physical fitness factors. Research articles were retrieved from 2008 to 2021 with the Research Information Sharing Service(RISS) and Pubmed database. The main search terms were 'care', 'therapy', 'healing', 'exercise' or 'physical activity', and 'virtual reality'. The criteria for selecting articles of this study were the originality, duplication, Randomized controlled trial(RCT) experiment and subject. Finally, 18 papers were selected among 318 articles, which were excluded if any of the criteria was not satisfied. Most of papers(15) were conducted in the last 5 years, because of the high interest due to the development of virtual reality implementation technology and COVID-19 pandemic. The participants were mainly patients(8), and the types of diseases were stroke(2). The physical fitness factors were mostly balance ability(7), muscle strength(7), and range of motion(6). All the physical fitness factors were significantly improved after PATPs. However, 11 studies were conducted for less than 4 weeks, including 6 studies were performed a bout of acute exercise. Also, 14 studies did not clearly present the intensity of PATPs. In addition, there were 9 studies, that simply applied games without specialized programs. In conclusion, it seems that virtual reality-based PATPs have a positive effect on physical fitness factors. However, VR-based PATPs should be specialized and developed in order to verify their effectiveness for the further research.

[Purpose] In this study, we investigated whether a 70% ethanolic (EtOH) extract of Sargassum horneri had antioxidant and anti-inflammatory effects in lipopolysaccharide (LPS)-stimulated macrophage-like RAW 264.7 cells. [Methods] The proximate composition, fatty acids, amino acids, and dietary fiber of S. horneri, various biologically active compounds, and antioxidant activity were analyzed. [Results] The DPPH and ABTS free radical scavenging activities, as well as the reduction power, of the S. horneri extract used here were significantly increased in a concentration-dependent manner. This indicates that S. horneri contains bioactive compounds, such as phenols and flavonoids, that have excellent antioxidant activity. The cellular viability and metabolic activity results confirmed that the extract had no discernible toxicity at concentrations up to 100 ㎍/mL. The levels of nitrites and cytokines (PGE₂, TNF-α and IL-6), which mediate pro-inflammatory effect, were significantly inhibited by treatment with either 50 or 100 ㎍/mL S. horneri extract, whereas that of IL-1β was significantly inhibited by treatment with 100 ㎍/mL of the extract. Similarly, the expression of iNOS and COX-2 proteins also decreased according to 50 or 100 ㎍/mL extract concentrations. NF-κB binding to DNA was also significantly inhibited by treatment with 100 ㎍/mL of extract. [Conclusion] These results suggest that 70% EtOH extracts of S. horneri can relieve inflammation caused by disease or high intensity exercise.
