Filter by:Although there is increasing evidence that low physical fitness is a risk factor for many non-communicable diseases, the early identification of subjects at risk remains inadequate due to the absence of clear anamnestic and clinical criteria. Defining physical fitness. For the same reason, the monitoring of subjects following lifestyle interventions remains suboptimal. The aim of this study is to develop a simple field tool to non-invasively assess global physical fitness in overweight patients participating to a physical activity program. Male and female overweight subjects referred to a physical activity intervention by their primary care physician will be included. Within this program, they will take part to 2 weekly supervised activity sessions during which participants will be instructed by a specialist in adapted physical activity, and 2-3 weekly session of unsupervised physical activity which will be performed according to detailed instructions regarding intensity and duration. In addition, participants will take part to teaching sessions in group of 4-6 patients, addressing the effects of physical activity on metabolism, contra-indications to physical activity, self-monitoring of exercise, and prevention of injuries Their physical fitness will be assessed at inclusion (ie before starting the exercise program) and at the end of the 3-month program. This will be done by calculating a Global Fitness Score (GFS) based on performances attained and cardiovascular responses observed during physical exercises (3 min step test with measurement of heart rate and blood pressure, number of time subject can stand from a chair within 1 min., handgrip strength measure, "reach-test" to assess osteo-articular mobility of back and hips, balance test). Results obtained from this GFS will be compared to maximal power output calculated from a submaximal spirometry at 25, 50, 75 and 100 W M.
It is estimated that 15% of adults aged 60-70 years, and up to 50% of adults aged 80 years and older are affected by sarcopenia—the age related loss of muscle mass and function. A disruption of the homeostatic balance between periods of muscle protein breakdown (predominant during fasting) and muscle protein synthesis (predominant following nutrient ingestion) can result in the loss of muscle mass over time. In particular, research suggests that an inability of muscle to fully respond to the anabolic influence of nutrient intake may contribute significantly to age-related muscle loss. This anabolic resistance is likely influenced by increased age-related inflammation. There is evidence in cell line and animal models that increased levels of the inflammatory cytokine, tumor necrosis factor-α (TNFα) impairs the molecular pathways that initiate muscle protein synthesis (i.e. mammalian target of rapamycin, mTOR signaling), and can accelerate muscle protein breakdown. Obesity, and sedentary lifestyle have been linked to increased TNFα expression, and thus may partially explain impaired muscle protein balance in older adults. The objectives of this clinical trial are to 1) determine if lifestyle modification via weight loss and aerobic exercise can reduce skeletal muscle inflammation and subsequently improve nutrient-stimulated muscle protein synthesis in previously sedentary, obese older adults; and 2) expose undergraduate Kinesiology and Nutrition majors to meritorious research. The investigators have recently published data with undergraduate researchers showing that body composition is associated with elevated skeletal muscle expression of TNFα converting enzyme (TACE). One of the primary actions of TACE is to cleave membrane bound TNFα (mTNFα) to soluble TNFα (sTNFα)—a more mature and bioactive form of TNFα. Both TACE and sTNFα are known to be elevated in a number of clinical conditions, including heart disease, cancer, arthritis, and diabetes. Based on these data, the investigators feel that TACE may represent an important and potentially modifiable (via weight loss and aerobic conditioning) regulator of skeletal muscle inflammation in humans. There are currently no data on the associations among skeletal muscle expression of TACE, TNFα, and muscle protein balance. Thus, the focus of this study is to determine if 5-10% diet-induced weight loss and 6-months (3 days per week) of aerobic exercise training can influence: 1) TACE and TNFα expression in skeletal muscle; and 2) improve molecular indices of muscle protein breakdown and nutrient-stimulated muscle protein synthesis (mTOR signaling) in sedentary, obese older adults. Specifically, 60 sedentary, obese older adults will be randomized to one of the following groups: 1) control group (CON), 2) a diet-induced weight loss group (DIET), 3) an aerobic exercise training group (EX), or 4) a diet-induced weight loss + aerobic exercise training group (DIET + EX). The results of this study will advance the understanding of the connections among skeletal muscle inflammation and muscle protein balance in older adults, and validate TACE as a potentially modifiable target for the prevention and treatment of sarcopenia and other age-related inflammatory diseases, which will contribute to the development of practice-based guidelines for healthcare practitioners.
Preeclampsia is a pregnancy-specific syndrome that affects 3 - 5% of pregnancies. It is one of the main causes of maternal, fetal and neonatal morbidity and mortality, resulting in approximately 40,000 maternal deaths worldwide each year. Fortunately, preeclampsia-related deaths have been reduced remarkably in recent decades thanks to improvements in antenatal care and therapeutic interventions, and prophylactic use of low-dose aspirin in women who are at a higher risk of developing preeclampsia. Effective prevention is rarely available for obstetric complications. Aspirin is one of them. Several meta-analyses456 suggested that aspirin prescription reduced the risk of preeclampsia and fetal growth restriction by 40-50% in an aspirin-dose-response pattern.
Background Atrial fibrillation (AF) affects over 1 million individuals in the UK and results in costs of over £450 million per year to the National Health Service (NHS). Current rhythm control strategies are limited by high recurrences of AF. New strategies tackling more upstream pathophysiological mechanisms are most needed. The incidence and prevalence of AF markedly increase with age, whilst obesity is the strongest modifiable risk factor for AF. Preliminary data in relatively young patients suggest that weight loss programmes may reduce AF burden and improve AF-related symptoms. Such programmes could be a widely-applicable and cost-effective option in AF management if they are also effective in elderly patients with AF, particularly if they also improve physical performance. Aim The aim of this study is to investigate whether, in older overweight/obese AF patients, referral to a weight loss programme with meal replacement & behavioral support can reduce AF-recurrences and improve physical performance compared to usual care. Study design Parallel-group, open-label, multi-centre randomised controlled trial. Elderly individuals (60-85 years) with persistent AF and elevated body mass index (BMI; ≥ 27 kg/m2) will be recruited. Participants will be randomly allocated (1:1) to (a) referral to a meal replacement programme with behavioral support (intervention) or (b) usual care (control) for 32-to-36 weeks. The primary endpoints are AF recurrence and physical performance test (PPT) score. Participants randomised to the study intervention will be referred to a commercial provider (CP) providing the intervention. The co-primary endpoints of AF recurrence & PPT score will be analysed irrespective of compliance during the scheduled treatment period following an intention-to-treat principle.
The main purpose of this study is to compare the impact of concurrent high-intensity interval training (HIIT) and whole-body electromyostimulation exercise (WB-EMS) or low-volume conventional strength training (CST) on the cardiometabolic risk profile, overall physical fitness (cardiorespiratory fitness and muscular strength), body composition, inflammatory markers and subjective health outcomes after a 12-week intervention trial in overweight individuals at increased cardiometabolic risk. Furthermore, this study aims to investigate the influence of intra-session exercise order on all outcomes.
The accumulation of excess of body weight is one of the most important problems worldwide, thus effective and accessible treatments are required. Some authors highlighted that treatment is focused solely on lifestyle (diet, physical activity, behavioral therapy) has a limited effect on body weight because it does not consider the biological mechanisms linked to weight loss in patients with obesity. On the other hand, drugs and bariatric surgery consider these biological approaches; however, its costs, safety and effectiveness limits its use on a large scale. Research studies support the existence of compounds in plants (such as epigallocatechin gallate, caffeine, cinnamaldehyde, fiber), and water with biological properties that would contribute to the treatment of overweight and obesity. However, at the moment, these compounds have only been evaluated individually and their effects have been significant but limited clinically, therefore, more research studies are needed to evaluate whether several of these compounds contained in common plants synergistically have a clinical impact on the management of overweight and obesity. The present work integrates diverse plant-based approaches to stop obesity and it is compared with a control group and a waiting list group. The main aim is to evaluate the efficacy of the Plant-based Approaches to Stop Obesity diet (PASO diet) compared with a control group on body weight at 3 months in Mexican adults with overweight and obesity. This is a pilot study designed as a randomized controlled trial. The study will be conducted with a (n=36). The primary outcome is the change in body weight from baseline to 3 months. Secondary outcomes will be the changes from baseline to 3 months in body mass index, waist circumference, systolic and diastolic blood pressure, symptoms of depression, quality of life scales and biochemical parameters (fasting glucose, total cholesterol, LDL cholesterol, HDL-cholesterol, triglycerides and gamma glutamyl transferase). Additionally two 24-hour dietary recall will be measured at baseline and 3 months to evaluate adherence to the intervention.
The aim of the study is to determine if time-restricted feeding (TRF) is an effective dietary strategy to weight loss after 8 weeks intervention. TRF will be compared with an intervention without restriction in time for feeding. Both strategies will be with caloric restriction.
