Monocentric unblinded two parallel-group randomized controlled trial to evaluate the effect of diet with or without Nordic Walking on weight loss, physical performance and cardiovascular risk factors in overweight and obese population
The aim of this study is to analyze the impact of physical exercise through a protocol of concurrent training in the psychological, physical, hormonal and sexual aspects in middle aged men with androgen deficiency in the aging male (ADAM). The study design with randomized clinical trial, comprising men in middle age (40 to 59 years) with ADAM, should be divided into two groups: 1) Control group (CG); 2) Experimental group (EG). Information related to sociodemographic and clinical profile will be collected; Psychological aspects (depressive and anxiety symptoms - Hospital Anxiety and Depression Scale ; stress - Perceived Stress Scale); Physical acpects (IMC; Percentage of body fat; Abdominal obesity - waist circumference in cm; Muscle strength - Biodex System 4 PRO isokinetic dynamometer; cardiorespiratory Fitness - Cycle-ergometer - CASE ECG Stress Testing System, General Electric Medical Systems, Milwaukee, WI); Hormonal aspects (total and free testosterone - blood collection); Sexual Aspect (Sexual satisfaction- International Index of Erectile Function); DAEM (scale of symptoms of aging). Apply a physical exercise protocol using the functional training method over a six-month period. All information will be collected before and after the intervention period. For statistical analysis, use the SPSS statistical package, version 20.0. (Kolmogorov-Smirnov or Shapiro-Wilk test) for the selection of statistical tests.
This randomized, placebo-controlled, double-blind, controlled study was designed to investigate the efficacy of electrical muscle simulation (EMS) for treatment of waist circumference (WC) reduction in abdominal obese adults. 60 patients with abdominal obese, man with WC > 90 cm and woman with WC > 80 cm, received EMS as experimental group (EG) or transcutaneous electrical nerve stimulation (TENS) as control group (CG) 5 times a week for 12 weeks.
The prevalence of overweight and lifestyle related diseases such as cardiovascular disease (CVD) and type 2 diabetes (T2D) is increasing world wide. The metabolic syndrome (MeS) is a condition characterized by abdominal obesity, high blood lipids, high blood pressure and elevated blood sugar. MeS is associated with an increased risk of developing CVD and T2D. Dietary fibers and whey protein have independently shown beneficial effects on several of these risk factors in previous studies. Whey protein is furthermore seen to show positive effects on bone turnover. The purpose of this trial is to investigate whether an increased intake of dietary fibers and whey protein (separately or combined) over a period of 12 weeks will affect the risk markers of MeS and bone turnover in abdominally obese subjects. A total of 80 people with abdominal obesity will be included. The design is a randomized, double blinded, controlled dietary intervention trial. Subjects are assigned to one of four experimental groups. Each group are provided with test products containing either high or low whey protein and high or low dietary fibers to replace part of their regular diet. The subjects are instructed in how to incorporate the test products in their habitual diets in order to maintain weight stability. The primary outcome is postprandial lipaemia (PPL) - an independent risk factor of developing CVD. PPL is estimated by performing a standardized high fat meal test during which postprandial level of triglycerides is measured. The authors hypothesize that a diet of high content of whey protein and high dietary fiber during 12 weeks will induce a reduction in PPL.
Aging has been associated with reduced bioavailability of nitric oxide (NO) and endothelial dysfunction. Beetroot consumption, a nitrate-rich food, has been associated with increased NO bioconversion, which may promote beneficial effects on vascular health. The present study evaluated the effects of a beetroot-based nutritional gel (BG) on vascular function, arterial stiffness and blood pressure in the elderly at cardiometabolic risk. Twenty elderly individuals were submitted to BG and nitrate-depleted gel (PLA) interventions. Brachial flow-mediated dilation (FMD), blood flow velocity (BFV), peak wave velocity (PWVβ), augmentation index (AI), stiffness parameter (β), pressure-strain elasticity modulus (Ep), arterial compliance (AC), muscle oxygenation and function were measured 90 min after interventions. Urinary nitrate, nitrite, systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) were measured at baseline, 90 min and 150 min after interventions.
The purpose of the WorkACTIVE-P study is to assess the outcome of an innovative multi-component intervention focused on increasing energy expenditure and re-balancing the disrupted energy balance equation of sedentary workplaces with an ultimate target of reducing workers' abdominal obesity.
To evaluate the effectiveness of acupuncture therapy combined with healthy education for patients with abdominal obesity.
Abdominal obesity and its metabolic consequences, particularly type 2 diabetes, require personalized nutritional monitoring. Today, it is not always possible to provide patients with appropriate care to both, the diet plan, physical activity, stress and sleep management. Emerging data have shown the effectiveness of remote support (e- coaching), in order to increase the level of physical activity and reducing calorie intake which causes weight loss similar to that obtained during a face to face consultation. Compared to a food survey conducted by a dietician, the dietary survey MXS computer software showed similar results on the collection of nutritional data. Furthermore, users preferred this method of remote collection compared to direct interview. The investigators recently developed a tool for e-coaching combining this computerized dietary survey and education and support modules on diet and physical activity (MXS- health program) for the patients. The aim of the investigators' study is to compare efficacy of this new software vs usual care.
In the Belly Fat study, the effects of two different caloric-restricted diets on metabolic health will be examined in male and female subjects with increased abdominal adiposity (BMI >27 kg/m2). Metabolic health is defined as health of the primary metabolic organs the liver, gut and the adipose tissue, examined in a static state as well as after the application of a challenge test. The diets are equally caloric-restricted, but differ in nutrient composition. It is hypothesized that one of the two diets causes a larger improvement in organ health and reduction in liver fat.
Currently, the incidence of obesity and obesity-related disorders is reaching epidemic proportions, which entails an increasing burden for health care systems. The association of obesity with other risk factors for type 2 diabetes mellitus and cardiovascular disease, such as insulin resistance and hypertension, is often referred to as the metabolic syndrome. During recent years, salt-sensitivity of blood pressure has emerged as an additional cardiovascular risk factor that is related to obesity and other key components of the metabolic syndrome. The underlying pathophysiological mechanisms of these interrelationships are complex and incompletely elucidated. Microvascular dysfunction has been proposed as a link between insulin resistance and hypertension in obese individuals. In addition, impairment of microvascular function was found to be associated with salt-sensitivity of blood pressure. Increased aldosterone levels, as observed in obese individuals, might be a cause of microvascular dysfunction-induced salt-sensitivity and insulin resistance. Aldosterone not only gives rise to sodium-retention in the distal tubule of the kidney, but was also found to impair endothelial function and thus lower NO-availability, which is characteristic of microvascular dysfunction. In addition, elevated aldosterone levels are associated with both hypertension and insulin resistance, which is illustrated in patients with primary aldosteronism, but also in the general population. The investigators hypothesize that increased aldosterone levels in obese individuals lead to impairment of microvascular function through reduction of NO-availability. This microvascular dysfunction is suggested to play a central role in the pathogenesis of salt-sensitive hypertension and insulin resistance.
