Effects of vitamin D supplementation and circuit training on indices of obesity and insulin resistance in T2D and vitamin D deficient elderly women. JENB., Vol. 18, No. 3, pp.249-257,2014 [Purpose]The purpose of this study was to investigate the effects of vitamin D supplementation and circuit training on body composition, abdominal fat, blood lipids, and insulin resistance in T2D and vitamin D deficient elderly women. [Methods]Fifty-two elderly women were randomly assigned to either the vitamin D supplementation with circuit training group (D+T: n= 15), the circuit training group (T: n = 13), the vitamin D supplementation group (D: n = 11), or the control group (CON: n= 13). The subjects in D took vitamin D supplements at 1,200 IU per day for 12 weeks; the subjects in T exercised 3 to 4times per week, 25 to 40 minutes per session for 12 weeks; and the subjects in D+T participated in both treatments. Subjectsin CON were asked to maintain normal daily life pattern for the duration of the study. Body composition, abdominal fat, bloodlipids, and surrogate indices for insulin resistance were measured at pre- and post-test and the data were compared among the four groups and between two tests by utilizing two-way ANOVA with repeated measures. The main results of the present study were as follows: [Results] 1) Body weight, fat mass, percent body fat, and BMI decreased significantly in T, whereas there were no significant changes in the variables in D and CON. Lean body mass showed no significant changes in all groups. 2) TFA and SFA decreased significantly in T, whereas there were no significant changes in the variables in D and CON. The other abdominal fat related variables showed no significant changes in all groups. 3) TC, TG, HDL-C, and LDL-C showed improvements in T, whereas there were no significant changes in the variables in D and CON. 4) Fasting glucose, fasting insulin, and HOMA-IRtended to be lower in D+T. [Conclusion]It was concluded that the 12 weeks of vitamin D supplementation and circuit training would have positive effects on abdominal fat and blood lipid profiles in T2D and vitamin D deficient elderly women. Vitamin D supplementation was especially effective when it was complemented with exercise training. [Key words]Diabetes, Circuit training, Vitamin D, Elderly, Abdominal fat, Insulin resistance.

Type 2 Diabetes: Endothelial dysfunction and Exercise. JENB., Vol. 18, No. 3, pp.239-247,2014 [Purpose]Vascular endothelial dysfunction is an early marker of atherosclerosis characterized by decreased nitric oxide bioavailability in the vascular endothelium and smooth muscle cells. Recently, some animal models and in vitro trials demonstrated that excessive superoxide production from mitochondria within vascular endothelial cells played a role in the pathogenesis of atherosclerosis in type 2 diabetes. This review provides a systematic assessment of the effectiveness of exercise to identify effective approaches to recognize diabetes risk and prevent progression to heart disease. [Methods]A systematic literature search was conducted to retrieve articles from 1979 to 2013 using the following databases: the MEDLINE, PubMed. Articles had to describe an intervention that physical activity and exercise to identify effective approaches to heart in people with Type 2 diabetes. [Results]Currently, physical activity and exercise guidelines aimed to improve cardiovascular health in patients with type 2 diabetes are nonspecific. Benefit of aerobic exercise training on vascular endothelial function in type 2 diabetic patients is still controversial. [Conclusion]it is necessary to demonstrate the mechanism of endothelial dysfunction from live human tissues so that we can provide more specific exercise training regimens to enhance cardiovascular health in type 2 diabetic patients. [Key words]Type 2 diabetes, vascular endothelial function, nitric oxide, flow-mediated dilation, oxidative stress, exercise training.

NAMPT regulates mitochondria biogenesis via NAD metabolism and calcium binding proteins during skeletal muscle contraction. JENB., Vol. 18, No. 3, pp.259-266, 2014 [Purpose]The purpose of this study was to investigate the effect that muscle contraction induced NAD metabolism via NAMPT has on mitochondrial biogenesis. [Methods]Primary skeletal muscle cells were isolated from the gastrocnemius in C57BL/6 mice. The muscle cells were stimulated by electrical current at 1Hz for 3 minutes in conditions of normal or NAD metabolism related inhibitor treatment.NAD/NADH level, Sirt1 and mitochondria biogenesis related signal factor's changes were examined in normal or NAD metabolism related inhibitor treated cells. [Results]Electrical stimulation (ES) induced muscle contractions significantly increased NAD/NADH levels, NAMPT inhibitor FK-866 inhibited ES-induced NAD formation, which caused SIRT1 expression and PGC-1α deacetylationto decrease. Moreover, NAMPT inhibition decreased mitochondrial biogenesis related mRNA, COX-1 and Tfam levels. Along with AMPK inhibitor, compound C decreases SIRT1 expression, PGC-1α deacetylation and muscle contraction induced mitochondrial biogenesis related mRNA increment. These results indicated that the AMPK-NAMPT signal is a key player for muscle contraction induced SIRT1 expression and PGC-1α deacetylation, which influences mitochondrial biogenesis. Inhibition of the AMPK upregulator, Camkkβ, STO-609 decreased AMPK phosphorylation and SIRT1 expression but did not decrease PGC-1α deacetylation. However, CAMKII inhibition via AIP decreased PGC-1α deacetylation. [Conclusion]In conclusion, the results indicate that NAMPT playsan important role in NAD metabolism and mitochondrial biogenesis. However, mitochondrial biogenesis is also controlled by different calcium binding protein signals including Camkkβ and CAMKII. [Keyword]Muscle contraction, NAD metabolism, SIRT1,PGC-1 α, mitochondria biogenesis.

The Effects of Pilates Exercise on Lipid Metabolism and Inflammatory CytokinesmRNA expression in Female Undergraduates. JENB., Vol. 18, No. 3, pp.267-275, 2014 [Purpose]The purpose of the study wasto verify the effects of Pilates exercise by observing the impact of 8 weeks of Pilates exercise on lipid metabolism and inflammatorycytokine mRNA expression in female undergraduates in their 20s who had no prior experience in Pilates exercise and had notexercised in the previous 6 months. [Methods] There were 18 subjects with no prior experience in Pilates exercise. The subjects were separated into the Pilates exercise group (n = 9) and the non-exercise control group (n = 9). The former performed Pilates exercise for 60-70 minutes over 8 weeks with a gradual strength increase of 9-16 in the Rating of Perceived Exercise (RPE). The body composition, creatine kinase in the bloodstream and lipid metabolism (TC, LDL-C, HDL-C, TG) were measured before and after the experiment and Real-Time PCR was used to investigate the mRNA expression of the inflammatory cytokines IL-6and TNF-?. [Results]The creatine kinase (CK) in the blood had significant differences between the groups. The test group showed significant increase compared to the control group after 8 weeks of Pilates exercise (p = 0.007). Lipid analysis showed that the level of high-density lipoprotein cholesterol (HDL-C) was significantly different in the two groups (p = 0.049), with the Pilatesexercise group exhibiting significantly higher levels compared to the control group. No significant differences were observed in the levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and triglyceride (TG). IL-6 mRNA expression did not show significant differences between the groups either. Timing and TNF-α mRNA expression showed significant effect in both the exercise and the control groups (p = 0.013) but no correlation. [Conclusion]It was found from the study that Pilates exercise for 8 weeks affected CK expression (the muscle damage marker) and induced positive changes in the levels of high-density lipoprotein. [Key words] Pilates, creatine kinase, lipid metabolism, inflammatory cytokine mRNA.

[Purpose]The purpose of the study was to investigate the effect of 12-week walking exercise on abdominal fat, insulinresistance and serum cytokines in obese women. [Methods]Following baseline measurements, obese women (N = 20) who met obesity criterion of BMI at 25 kg/m2or greater were randomly assigned to the control (n = 10) or exercise groups (n = 10). Women assigned to the exercise group participated in a walking exercise (with an intensity of 50-60% of predetermined VO2max, a frequency of 3 days per week and duration of 50-70 minutes targeting 400 kcal of energy expenditure per session) for 12 weeks, while women assigned to the control group maintained their sedentary lifestyle. After the 12-week walking intervention, post-test measurements were conducted using the same procedure as the baseline measurement. Analyses of variance with repeated measures were used to evaluate any significant time by group interactions for the measured variables. [Results]With respect to body fat parameters, significant time-by-group interactions were found in the abdominal subcutaneous (p = < 0.001) and visceral adipose tissues (p =0.011). The exercise group had significant reductions in both subcutaneous and visceral adiposity, and the control group hadno significant changes in those parameters. Similarly, there were significant time by group interactions in fasting glucose (p =0.008), HOMA-IR (p = 0.029), serum TNF-α (p = 0.027), and IL-6 (p = 0.048) such that the exercise group had significant reductions in those parameters, with no such significant changes found in the control group. The exercise group also had a significant increasein serum adiponectin (p = 0.002), whereas the control group had no significant change in the parameter. [Conclusion]In summary, the current findings suggest that walking exercise can provide a safe and effective lifestyle strategy against abdominal obesity and serum insulin resistance markers in obese women.

A survey of overweight, body shape perception and eating attitude of Korean female university students. JENB., Vol. 18, No. 3, pp.287-292, 2014 [Purpose]We obtained basic data on a proper weight loss training program by consideringthe relationship between body mass index (BMI), the perception of appearance, and eating attitudes of Korean female university students. [Methods]The survey and anthropometry for the perception of appearance and eating attitudes were conducted targeting657 female university students located in Seoul, Busan, Ulsan, Daejeon, Chungcheongnam-do, and Gangwon-do South Korea who were not specializing in physical education. [Results]The underweight group accounted for 21.16% of the population, the normal weight group comprised 69.71%, the overweight group was 6.09%, and the obese group accounted for 3.04%. The satisfaction rate of appearance was 56.16%, the dissatisfaction rate was 43.84%, and normal-weight students who were dissatisfied with theirown appearance comprised 48.5%. The More obese students were more dissatisfied with their appearance. As a result of investigating eating attitudes, 37.75% of all subjects had a risk for an eating disorder, and 38.6% were normal weight but showed a risk foran eating disorder. More obese (BMI) subjects were at higher risk for an eating disorder. [Conclusion]The BMIs of the Korean female university students were lower than those of European and American Caucasian women students, but the dissatisfaction of Korean female university students with their appearances was greater than that of European and American students, indicating that more Korean female university students were suffering from an eating disorder. It is predicted that the incidence of eating disorders, such as anorexia and bulimia, will rise in Korean women if there is no accurate understanding and measure to identify the high risk group for an eating disorder.

[Purpose]The objectives of the present study were to determine the effect of sun exposure and aerobic exercise on quality of sleep and investigate sleep-related hormonal responses in college-aged males. [Methods]In this study, the cross-over design was utilized. The subjects (N = 10) without any physical problems or sleep disorders participated in the experimental performed 4 protocols in only sun exposure (for 30 minutes, EG1) protocol, only aerobic exercise (walking and jogging for 30 minutes, EG2) protocol, aerobic exercise with sun exposure (EG3) protocol, and control (no exercise and no sun exposure, EG4) protocol. Each protocol was 5 times per week with one-week break (wash-out period) between protocolsto prevent the effects of the previous protocol. Total test period was should be 7 weeks (one week of protocol and one week of break). Before and after each aerobic exercise session, the subjects completed stretching to warm up for 5 to 10 minutes. Surveys consisting of (bedtime, wake-up time, sleep onset latency, and (Pittsburgh Sleep Quality Index (PSQI) were obtained before the test and after each protocol. After each protocol, the following sleep-related hormonal responses were measured: blood concentrations of melatonin, cortisol, epinephrine, and norepinephrine. One-way ANOVA was used to determine differences between protocols. Statistical significance was set at p < 0.05. [Results]Bedtime of EG4 was significantly later than that of the EG1 orEG3. Wake-up time in the EG4 was significantly later than that of the EG1 or the EG3. Sleep onset latency in the EG4 waslonger than that of the EG3. The quality of sleep in the EG4 was lower than that of the EG3. Sleep cycle in the EG4 was significantly shorter than that of the EG1. Blood melatonin concentrations of the EG3 was significantly higher than that of theEG4. There were no significant differences in blood concentrations of cortisol, epinephrine, or norepinephrine among protocols, with the order from the lowest to the highest values of EG1 < EG2 < EG3 < EG4. [Conclusion]The present data found that EG1and EG3 showed positive sleep-related hormonal responses, sleep habits, and quality of sleep, indicating that sun exposure orexercise with sun exposure may improve the physical status and quality of life.

Antioxidant and antiapoptotic effects of pine needle powder ingestion and endurancetraining in high cholesterol-fed rats. JENB., Vol. 18, No. 3, pp.301-309, 2014 [Purpose]Pine needle is a kind of medicinal plantingested traditionally for a variety of purposes. Therefore, we examined the antioxidant and antiapoptotic capacities of pine needle ingestion in high cholesterol-fed and endurance exercise-trained rats. [Methods]Animals were divided into six groups as; CON: normal diet control group; EX: normal diet and exercise training group; HC: high cholesterol diet group; HCE: high cholesterol diet and exercise training group; HCP: high cholesterol and pine needle group; HCPE: high-cholesterol and pine needle diet with exercise training group, respectively. Each group consisted of seven Sprague-Dawley male rats. The swim-training groups, EX,HCE, and HCPE swam in the swim pool 60 min/d and 5 d/week for 5 weeks. During the rearing periods, freeze-dried pineneedle powder mix with 5% of the high cholesterol diet was supplied to the HCP and HCPE groups. Gastrocnemius musclewas used as the skeletal muscle. Malondialdehyde (MDA), Mn-containing superoxide dismutase (Mn-SOD), Cu, Zn containing superoxide dismutase (Cu,Zn-SOD), and glutathione peroxidase (GPx) were analyzed for their antioxidant capacities. Finally, p53,Bcl-2 (B-cell lymphoma 2), caspase-3 protein expression was analyzed to determine antiapoptotic ability. [Results]MDA showed low content in HCPE compared to the HC. Mn-SOD, Cu, Zn-SOD, and GPx protein expression was significantly increased by pine needle ingestion and/or exercise training. In addition, suppression of p53 protein expression resulted in Bcl-2 increase followed by caspase-3 decrease with/without pine needle ingestion and exercise training. [Conclusion]When exercise training in addition to pine needle powder ingestion may be a helpful nutritional regimen to athletes and exercisers.

[Purpose]This study suggests that the negative effects of inflammation caused by obesity could be prevented through diet restriction and exercise. [Methods]In this study, 44 C57/BL6 male mice at about 4 weeks old (Orient bio, South Korea) were given a high fat dietfor 5 weeks to make them obese. To help the mice lose weight, their dietary intake was limited and they were exercised on the treadmill for 8 weeks, and during that period, we analyzed the changes of MCP-1, ERK, Mn-SOD, HIF-1, and NOX in epididymaladipose tissue. There ND control group and obese group with high fat diet (HFD), and it is divided into four groups; HFD-ND-EX group, HFD-ND-nonEX group, HFD-DR-EX group and HFD-DR-nonEX group. [Results]During their progress, the mRNA expressions of HIF-1α and ERK2 decreased, as did the the expression of MCP-1 contained in the nucleus by suppressing oxygen free radicals, which was observed after the exercise program. However, dietary restriction without exercise training triggered an increase in the mRNA expression of MCP-1. [Conclusion]To put this in perspective, combining exercise and dietary intake restriction likelyprevented an influx of macrophages by reducing the number of fat cells, whereas only dietary restriction was not effective against reducing inflammation. [Key word] obesity, diet restriction, MCP-1, inflammation.
