Effects of Exercise Training during Christmas on Body Weight and Cardiometabolic Health in Overweight Individuals

Individuals with abdominal obesity and metabolic syndrome (MetS) have augmented risk of all-cause mortality. Lifestyle interventions are effective to treat MetS, however, there are periods during the year in which exercise programs are discontinued and improper dietary habits reappear (e.g., Christmas holidays). We aimed to analyze if exercise-training during Christmas holidays would avoid body-weight gains and cardiometabolic deterioration in MetS individuals, using a randomized control trial. Thirty-eight men with MetS undergoing exercise training were randomly allocated to either continue (TRAIN group, n = 16) or discontinue (HOLID group, n = 22) training, during the three weeks of Christmas. Anthropometrics (body weight, fat, and waist circumference), fasting blood metabolites (glucose, insulin, triglycerides, and cholesterol concentrations) and exercise maximal fat oxidation (FOMAX) and oxygen uptake (VO2PEAK) were determined before and after Christmas. Both groups were similar at baseline in all parameters (p > 0.05). HOLID group increased body weight (91.3 ± 13.0 to 92.0 ± 13.4 kg, p = 0.004), mean arterial pressure (94.0 ± 10.6 to 97.1 ± 8.9 mmHg, p = 0.026), blood insulin (10.2 ± 3.8 to 12.5 ± 5.4 µIU·mL−1, p = 0.003) and HOMA (3.2 ± 1.3 to 4.1 ± 2.3, p = 0.003). In contrast, TRAIN prevented those disarrangements and reduced total (170.6 ± 30.6 to 161.3 ± 31.3 mg·dL−1, p = 0.026) and low-density lipoprotein cholesterol (i.e., LDL-C, 104.8 ± 26.1 to 95.6 ± 21.7 mg·dL−1, p = 0.013). TRAIN also prevented the reductions in exercise FOMAX and VO2PEAK that was observed in the HOLID group (p = 0.002). In conclusion, exercise training during Christmas, prevents body weight gains and the associated cardiovascular (increase in blood pressure and LDL-C) and metabolic (reduced insulin sensitivity) health risks are an optimal non-pharmacological therapy for that period of the year.

ObjectiveTo determine the effect of prolonged exposure to a submarine environment on biomarkers of cardiometabolic risk in Royal Navy (RN) submariners.MethodsSerum lipids (cholesterol (C), triglyceride (TG), low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL-C), non-HDL-C), glucose, insulin and anthropometrics were compared within three RN submarine crews before and after submerged patrols of 12 or 6 weeks, and with a crew that remained ashore (SUB-HOME). Dietary intake and activity patterns were self-reported during each patrol. Differences were assessed in crew characteristics using one-way analysis of variance and in serum lipids using paired t-tests.ResultsPostpatrol, the mean body weight of submerged crews decreased (−1.4±4.2 kg, p=0.0001), but increased in SUB-HOME (1.9±1.8 kg, p=0.0001). Modest improvements in serum lipids (mean individual change (mmol/L); C=−0.3±0.7, p=0.0001; TG=−0.3±0.7, p=0.0001; HDL-C=−0.1±0.3, p=0.0001; non-HDL-C=−0.2±0.6, p=0.012), glucose (−0.2±0.5, p=0.0001) and insulin (−1.5±4.6 mU/L, p=0.001) were observed in submerged crews. Changes in serum lipids were positively associated with changes in body weight within crews combined. Energy intake was maintained during submerged patrols but was lower compared with non-submerged (11 139±2792 vs. 9617±2466 kJ, p=0.001; 11 062±2775 vs. 9632±2682 kJ, p=0.003).ConclusionsThe environment of a submerged submarine produced no adverse effects on serum biomarkers of cardiometabolic risk in crew. Conversely, modest improvements in these biomarkers were associated with a decrease in body weight.

Arterial Dilation

ObjectiveImpairment of flow-mediated endothelium-dependent arterial dilation (FMD) exists in patients with subclinical hypothyroidism (sHT). Several studies showed that exercise training can improve FMD in patients with type 1 and type 2 diabetes. Therefore, we hypothesized that exercise training can also improve FMD in subjects with sHT. The purpose of the study was to test this hypothesis.Research design and methodsWe selected 30 sedentary women with sHT and 27 sedentary healthy women with euthyroid. All individuals participated in an exercise training of 6 months. Before and after exercise training, high resolution ultrasound was used to measure FMD.ResultsAt baseline, FMD among subjects with sHT was 3.87%, which was significantly lower than that in controls (5.98%; P<0.001). After 6 months of exercise, there was a remarkable increase in FMD (31.3%) and VO2 max (36.7%; P<0.01), and significant decreases in total cholesterol (20%), low-density lipoprotein cholesterol (LDL; 29%), triglycerides (TG; 47.6%), and C-reactive protein (CRP; 61.5%; P<0.05) were observed over the exercise in patients with sHT. The absolute changes in FMD showed significant correlation with changes in LDL (r=−0.596), TG (r=−0.532), and CRP (r=−0.511; P<0.01), and multiple regression analysis showed changes of LDL, TG, CRP were significant determinants of changes of FMD in sHT patients during exercise course.ConclusionRegular aerobic exercise improves FMD in sHT patients, and changes of lipids and inflammation during the exercise period may partially contribute to the improvement of endothelial function.

Before And After

PurposeSprint interval training (SIT) provides a strong stimulus for improving cardiovascular fitness, which is among the key markers for premature mortality. Recent literature demonstrated that SIT protocols with as few as two stacked 20 s Wingate Anaerobic Test (WAnT) cycle sprints provide sufficient training stimulus for a robust increase in maximal aerobic power. However, this effect is lost when only one bout is performed. This suggests training adaptation is still dependent on the volume of SIT. Therefore, the purpose of this study was to determine the effects of three dispersed 30 s WAnT bouts, done over a day but interspersed with 4 hours of recovery time, on selected cardiometabolic health markers.MethodsEighteen sedentary women, age 36±8 years, were recruited and underwent 8 weeks of supervised training using the WAnT protocol, 3 days a week. Criterion measure of cardiovascular fitness (ie, V̇O2peak), skinfolds and blood lipids such as triglyceride, low density lipoprotein (LDL) and high density lipoprotein (HDL) were measured before and after training intervention.ResultsV̇O2peakimproved by a mean of 14.0% after training (21.7±5.7 vs 24.7±5.7 mL/kg/min, p<0.01). No significant change was observed for body fat and lipid profile.ConclusionPerforming three dispersed WAnT bouts with a 4-hour recovery period between bouts throughout a day, 3 days per week for 8 weeks provides sufficient training stimulus for a robust increase in V̇O2peak, which is comparable with other previous SIT protocols with very short recovery intervals. However, no other changes in the other cardiometabolic health markers were detected.

Controlled Clinical Study

Dyslipidemia and oxidative modifications of lipid are frequently associated in patients with chronic kidney diseases (CKD) and considered the most important risk factors for cardiovascular events. Melatonin is a well-known potent antioxidant and has beneficial effect on lipid metabolism. the study was designed to evaluate if Melatonin could improve lipid profile and ameliorates lipid peroxidation. This single blind placebo controlled clinical study carried out on 41 patients with CKD who were randomized into two groups, control groups (n=20) those who received placebo cap and melatonin group those who received 5mg melatonin (n=21). Lipid profile [total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL-C), low-density lipoprotein (LDL-C)] and parameters of lipid peroxidation [oxidized LDL (oxLDL) and malondialdehyde (MDA) were measured before and after 12 weeks of the treatment. After 12 weeks of treatment, melatonin significantly increased HDL-C and decreased LDL-C compared to the initial value. The elevation in HDL-C and reduction in LDL-C were significantly different from that in placebo group. Also, both oxLDL and MDA levels significantly lowered by melatonin compared to the baseline and to the placebo group. Collectively, the results of our study showed that melatonin has advantageous effect on lipid profile and inhibit lipid peroxidation in patients with CKD.

Background and Objective: Yoghurt, especially bio-yoghurt has long been recognized as a product with many health benefits for consumers. Also, honey and olive oil have considerable nutritional and health effects. So, the effect of administration of yoghurt made using ABT culture and fortified with honey (2 and 6%), olive oil (1 and 4%) or honey + olive oil (2+1 and 6+4% respectively) on some biological and hematological properties of rats was investigated.Methods:The body weight gain, serum lipid level, blood glucose level, serum creatinine level, Glutamic Oxaloacetic Transaminase (GOT) activity, Glutamic Pyruvic Transaminase (GPT) activity, leukocytes and lymphocytes counts of rats were evaluated.Results:Blending of bio-yoghurt with rats' diet improved body weight gain. Concentrations of Total plasma Cholesterol (TC), High-Density Lipoprotein cholesterol (HDL), Low-Density Lipoprotein cholesterol (LDL), Very Low-Density Lipoprotein cholesterol (VLDL) and Triglycerides (TG) significantly lowered in plasma of rats fed bio-yoghurt. Levels of TC, LDL, VLDL, and TG also decreased in rat groups feed bio-yoghurt supplemented with honey and olive oil. LDL concentrations were reduced by 10.32, 18.51, 34.17, 22.48, 43.30% in plasma of rats fed classic starter yoghurt, ABT yoghurt, ABT yoghurt contained 6% honey, ABT yoghurt contained 4% olive oil and ABT yoghurt contained 6% honey + 4% olive oil respectively. The blood glucose, serum creatinine, GOT and GPT values of rats decreased while white blood cells and lymphocytes counts increased by feeding bioyoghurt contained honey and olive oil.Conclusion:The findings enhanced the multiple therapeutic effects of bio-yoghurt supplemented with honey and olive oil.

AbstractDyslipidemia is one of the main risk factors for coronary heart disease (CHD). The E3 ubiquitin ligase which is encoded by the ring finger protein 145 (RNF145) gene is very important in the mediation of cholesterol synthesis and effectively treats hypercholesterolemia. Thus, the purpose of the present research is to investigate the connection between the polymorphism of the RNF145 gene and cholesterol levels in the populations in Xinjiang, China. A total of 1396 participants (Male: 628, Female: 768) were included in this study for genetic analysis of RNF145 gene, and we used the modified multiple connection detection response (iMLDR) technology to label two SNPs (rs17056583, rs12188266) of RNF145 genotyping. The relationship between the genotypes and the lipid profiles was analyzed with general linear model analysis after adjusting confounding variables. Through the analysis of the two SNPs in RNF145 gene, we discovered that both rs17056583 and rs12188266 were related to total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) concentrations (All P < 0.001). In addition, the association of rs17056583 and rs12188266 with lipid profiles concentrations is still statistically significant after multivariate adjustment of sex, age, smoking, obesity, drinking, diabetes, hypertension and lipid profiles. Meanwhile, we also found that rs17056583 was associated with high triglycerides concentrations before and after adjustment (All P < 0.001). Our study shows that both rs17056583 and rs12188266 SNPs of RNP145 gene are related to TC and LDL-C concentrations in Xinjiang population.

Data Driven Decisions

Isotemporal substitution modelling (ISM) and compositional isotemporal modelling (CISM) are statistical approaches used in epidemiology to model the associations of replacing time in one physical behaviour with time in another. This study’s aim was to use both ISM and CISM to examine and compare associations of reallocating 60 min of sitting into standing or stepping with markers of cardiometabolic health. Cross-sectional data collected during three randomised control trials (RCTs) were utilised. All participants (n = 1554) were identified as being at high risk of developing type 2 diabetes. Reallocating 60 min from sitting to standing and to stepping was associated with a lower BMI, waist circumference, and triglycerides and higher high-density lipoprotein cholesterol using both ISM and CISM (p < 0.05). The direction and magnitude of significant associations were consistent across methods. No associations were observed for hemoglobin A1c, total cholesterol, or low-density lipoprotein cholesterol for either method. Results of both ISM and CISM were broadly similar, allowing for the interpretation of previous research, and should enable future research in order to make informed methodological, data-driven decisions.

Introduction: The delipid extracorporeal lipoprotein filter from plasma (DELP) has been approved for the treatment of acute ischemic stroke (AIS) by the China Food and Drug Administration, but its effectiveness and mechanism are not yet fully determined. The purpose of this study was to evaluate the effect of DELP treatment on AIS patients after intravenous thrombolysis. Methods: A retrospective study was performed on AIS patients with no improvement within 24 h after intravenous thrombolysis who were subsequently treated with or without DELP. Primary outcome was the proportion with a modified Rankin scale (mRS) of 0–1 at 90 days. Secondary outcomes were changes in National Institute of Health Stroke Scale (NIHSS) score from 24 h to 14 days after thrombolysis, and the rate of improvement in stroke-associated pneumonia (SAP). The main safety outcomes were the rates of symptomatic intracranial hemorrhage and mortality. To investigate its mechanisms, serum biomarkers were measured before and after DELP. Results: A total of 252 patients were recruited, 63 in the DELP group and 189 matched patients in the NO DELP group. Compared with the NO DELP group, the DELP group showed an increase in the proportion of mRS 0–1 at 90 days (p = 0.042). More decrease in NIHSS from 24 h to 14 days (p = 0.024), a higher rate of improvement in SAP (p = 0.022), and lower mortality (p = 0.040) were shown in DELP group. Furthermore, DELP decreased levels of interleukin (IL)-1β, E-selectin, malondialdehyde, matrix metalloprotein 9, total cholesterol, low-density lipoprotein, and fibrinogen, and increased superoxide dismutase (p< 0.05). Conclusions: DELP following intravenous thrombolysis should be safe, and is associated with neurological function improvement, possibly through multiple neuroprotective mechanisms. Prospective trials are needed.

Subcutaneous Adipose

Adipose tissue is an important site of clearance of circulating triacylglycerol (TAG), especially in the postprandial period. Postprandial lipemia is usually increased in obesity. We studied the extraction of TAG from plasma and TAG-rich lipoproteins (TRLs) in subcutaneous adipose tissue in 11 control and 8 obese subjects before and after a mixed meal. Clearance of plasma TAG and very low-density lipoprotein (VLDL)-TAG was decreased in the obese subjects after an overnight fast. After the meal, chylomicron-TAG extraction increased in the control group whereas VLDL-TAG clearance decreased; these changes were not seen in the obese group, in whom the VLDL particles appeared to be better able to compete with the chylomicrons for clearance by lipoprotein lipase. In the control subjects, removal of TAG from the TRL in the postprandial period was accompanied by a shift toward addition of cholesterol to the high-density lipoprotein (HDL) fraction; this was not observed in the obese subjects. We conclude that disturbed TRL-TAG clearance in adipose tissue is related both to the elevated plasma TAG concentrations and the depressed HDL-cholesterol concentrations typical of obesity.
