Filter by:Background: The relationship between the frequency of high-intensity interval training (HIIT) and the resultant adaptations is largely unclear. Purpose: This study examined the effects of different frequencies of HIIT compared to moderate-intensity continuous training (MICT) on body composition and cardiovascular biomarkers in overweight or obese adults. Methods: This study was a randomized, controlled, single-blinded trial. Fifty-six overweight or obese men aged between 18 and 30 years were randomly assigned to no-intervention control (CON; n=14), MICT performed thrice weekly (MICT×3/wk; n=9), HIIT performed thrice weekly (HIIT×3/wk; n=14), HIIT performed twice weekly (HIIT×2/wk; n=10), and HIIT performed once weekly (HIIT×1/wk; n=9). Each HIIT session consisted of 12 × 1-min bouts at 90% heart rate reserve (HRR), interspersed with 11 × 1-min bouts at 70% HRR (HIIT×3/wk: 69 min/wk; HIIT×2/wk: 46 min/wk; HIIT×1/wk: 23 min/wk). Aerobic capacity, resting heart rate, body composition, waist circumference, blood pressure, endothelial function, fasting blood glucose and lipids, circulatory adipokines and inflammatory biomarkers were examined at baseline, after 4 weeks and 8 weeks of intervention.
The PERGROUP trial aims to investigate whether Web-based personal or Web-based group counselling weight management program can help to achieve lifestyle changes needed for weight loss and improvement in quality of life and cardiovascular risk factors. The control group is the traditional nurse-lead weight management group counselling.
Plant-based nutrition may have positive effects on chronic diseases such as cardiovascular or metabolic disorders. This study investigates the effects of a 8 week plant-based diet for patients with metabolic syndrom and cardiovascular risk factors.
This study seeks to confirm and extend previous finding that four weeks of daily intake of 40 g of walnuts improve microvascular function, increasing the reactive hyperemia index (RHI), effects which were greatest in individuals with the worst initial RHI and correlating to circulating levels of vasoactive plasma epoxides. The current trial will enroll postmenopausal women who are at risk for cardiovascular disease due to their menopausal status and increased central adiposity. The initial trial focused on non-esterified (i.e. plasma) derived oxylipins, but substantial and unique changes were also observed in the esterified lipoprotein pool. The current study will add the esterified lipoprotein pool, important, as the mechanisms by which walnut intake influences endothelial function are currently undefined, but may include lipoprotein induced modulation of vascular hemostasis. As a secondary objective, primary metabolism and urolithin metabotype will be analyzed as a way to capture the influence of potential differences in habitual diet and metabolism on physiologic response. Therefore, this study will combine measures of cardiovascular physiology, metabolomics, and walnut-derived metabolite analyses to assess the 12 week influence of 40 g of daily walnut intake on the health of overweight and obese postmenopausal women.
The DELPhi system is a software device that is used for the noninvasive evaluation of brain plasticity and connectivity. The DELPhi software uses EEG and TMS devices as accessories. Standard electro-physiological acquisition is performed using TMS to evoke regional neuronal potentials measured as EEG data. TMS-EEG data is analyzed with regards to conventional, well established characteristics of neuronal network plasticity and connectivity.
The investigators aim to test an evidence-based intervention, allocated to a mobile app designed to parents and their children with 3 to 6 years old, identified by family doctors or nurses at well-child care visits as overweight or obese for age. This intervention aims to improve parent's perceptions and attitudes regarding children's weight status and food intake, leading to better dietary intake and children's' eating behaviors through positive parental child-feeding practices. In this study, the investigators aim to assess the feasibility of the intervention and explore its impact on the beliefs and attitudes of parents.
Good nutritional status of patients with Crohn's disease (CD) is associated with better outcome of the disease and better health-related quality of life. The prevalence of malnutrition in patients with Crohn's disease varies and is higher in patients with active disease. Available studies in the literature have assessed the nutritional status of patients with Crohn's disease. However, sample size of available studies is small and highly heterogeneous, and most patients are hospitalized with active disease. The aim of the present study is a thorough assessment of nutritional status of 250 patients either with active Crohn's disease or in remission of the disease using multiple widely available tools and methods, in order to assess their accuracy and estimate the prevalence of multiple malnutrition phenotypes such as undernutrition, sarcopenia, sarcopenic obesity and cachexia as well as overweight and obesity. Finally, the effect of the nutritional status on the course of the disease will be investigated.
The aim of the present study is to investigate effects of 12 weeks time-restricted eating on behaviour and metabolism in individuals with overweight or obesity at high risk of type 2 diabetes.
The purpose of this pilot study is to examine the effects of different types of just-in-time intervention messages on daily meeting dietary, activity, and weighing goals in a sample of young adults participating in a mobile-based weight loss program.
Overweight and obesity prevalence in adolescents and adults continues to remain significantly high in the United States. While diet and exercise improve many consequences of obesity, dietary strategies are not always nutrient sufficient and manageable long-term. Thus, highly complaint dietary strategies that lead to fat loss, while maintaining muscle mass, are needed. Time-restricted feeding (TRF) may be an ideal dietary approach for reducing fat mass and cardiovascular disease risk, while diminishing the loss of muscle mass and strength associated with obesity and aging. TRF, unlike continuous energy restriction, does not require a restrictive energy intake10. TRF requires individuals to consume calories within a set window of time (example = 8 hours), inducing a fasting window of 16 hours per day. There are few human studies on TRF that measure their effects in combination with both aerobic and resistance training. One recent study found an 8-hour TRF program (16-hour fast) improved insulin sensitivity, decreased fat mass, and maintained muscle mass in resistance-trained males after 8 weeks. Thus, the feasibility of TRF as dietary approach should be investigated further.The aims of this study are to: 1) determine whether time-restricted feeding (TRF) is an effective dietary strategy for reducing fat mass while preserving fat-free mass with aerobic and resistance training; 2) evaluate potential changes in health-related biomarkers (cardiovascular profile and anabolic-catabolic hormones) and muscle health indicators (mass, strength and quality) after 8 weeks of concurrent training with TRF; and 3) examine the influence of caloric intake and macronutrient consumption on muscle health in the TRF and normal feeding (NF) groups pre- to post-concurrent resistance training.
