OBJECTIVE: To analyze the association between the Trp64Arg polymorphism of the ADRB3 gene, maximal fat oxidation rates (FATMAX) and the lipid profile levels in non-obese adolescents. METHODS: 72 schoolchildren, of both genders, aged between 11 and 17 years, participated in the study. The anthropometric and body composition variables, in addition to total cholesterol (TC), high density lipoprotein (HDL-c), low density lipoprotein (LDL-c), triglycerides (TG), insulin (INS), and basal glycemia (GLIC), were evaluated...

Exercise stress testing is a validated diagnostic test for coronary artery disease in symptomatic patients, and is used in the evaluation of patients with known cardiac disease. Testing of asymptomatic patients is generally not indicated. It may be performed in select deconditioned adults before starting a vigorous exercise program, but no studies have compared outcomes from preexercise testing vs. encouraging light exercise with gradual increases in exertion. Preoperative exercise stress testing is helpful for risk stratification in patients undergoing vascular surgery or who have active cardiac symptoms before undergoing nonemergent noncardiac surgery...

To examine the temporal effects of high-intensity exercise on learning, short-term and long-term retrospective memory and prospective memory. Among a sample of 88 young adult participants, 22 were randomized into one of four different groups: exercise before learning, control group, exercise during learning and exercise after learning. The retrospective assessments (learning, short-term and long-term memory) were assessed using the Rey Auditory Verbal Learning Test. Short-term memory included a 20-min delay assessment, with long-term memory including a 24-hour follow-up assessment...

OBJECTIVE: Rates of mild cognitive impairment and Alzheimer's disease are increasing rapidly. None of the current treatment regimens for Alzheimer's disease are effective in arresting progression. Lifestyle choices may prevent cognitive decline. This study aims to clarify which factors best predict cognitive function. METHODS: This was a prospective cross-sectional analysis of 799 men and women undergoing health and cognitive testing every 1 to 3 years at an outpatient center...

Background Cardiorespiratory fitness training is commonly provided to manual wheelchair users (MWUs) in rehabilitation and physical activity programs, emphasizing the need for a reliable task-specific incremental wheelchair propulsion test. Objective Quantifying test-retest reliability and minimal detectable change (MDC) of key cardiorespiratory fitness measures following performance of a newly developed continuous treadmill-based wheelchair propulsion test (WPTTreadmill). Methods Twenty-five MWUs completed the WPTTreadmill on two separate occasions within one week...

OBJECTIVE: Physical exercise contributes to improving stability against nerve injury caused by ischaemic stroke. Here we aimed to preliminarily investigate the effects of continuous endurance training (CET) and high-intensity interval training (HIT) on stroke-associated anxiety, locomotion, neurological assessments and P70S6 Kinase (P70S6K) activation as well. To do this, rats were trained according to HIT and CET protocols for 2 months prior to being subject to middle cerebral artery occlusion surgery...

BACKGROUND: In this double-blind randomized placebo-controlled crossover trial, we investigated whether oral sodium nitrate, when added to existing background medication, reduces exertional ischemia in patients with angina. METHODS AND RESULTS: Seventy patients with stable angina, positive electrocardiogram treadmill test, and either angiographic or functional test evidence of significant ischemic heart disease were randomized to receive oral treatment with either placebo or sodium nitrate (600 mg; 7 mmol) for 7 to 10 days, followed by a 2-week washout period before crossing over to the other treatment (n=34 placebo-nitrate, n=36 nitrate-placebo)...

PURPOSE: Cardiac rehabilitation programs (CRPs) remain underutilized partly because of access barriers. We therefore evaluated a CRP with fewer center-based sessions (rCRP) compared with standard CRP (sCRP) with respect to changes in exercise capacity and cardiac risk factors. METHODS: In this randomized controlled noninferiority trial, primary and secondary prevention patients at low and moderate risk were randomized to an sCRP (n = 60) or an rCRP (n = 61). Over 4 months, sCRP and rCRP participants attended 32 and 10 on-site cardiac rehabilitation sessions, respectively...

Aerobic exercise (AE) and non-aerobic neuromuscular electric stimulation (NMES) are common interventions used in physical therapy. We explored the dose-dependency (low, medium, high) of these interventions on biochemical factors, such as brain derived neurotrophic growth factor (BDNF), vascular endothelial growth factor-A (VEGF-A), insulin-like growth factor-1 (IGF-1) and Klotho, in the blood and brain of normal rats, as well as a treadmill-based maximum capacity test (MCT). A medium dose of AE produced the most improvement in MCT with dose-dependent changes in Klotho in the blood...

Purpose: The aim of this study was to examine physiological responses to two different simulated firefighting exercises: a firefighting exercise with flashovers, smoke, poor visibility and extreme temperatures (300°) in a burning container and a standard firefighting exercise in temperate conditions. Furthermore, a second purpose of the study was to find out if the contribution of strength and endurance capacities to firefighting performance changes when the demands of the firefighting exercise change. Methods: Sixteen professional firefighters performed a maximum treadmill test, strength testing, a standard simulated firefighting exercise (SFE) without heat and flashovers and a firefighting exercise with a simulation of the flashover phenomenon in a burning container (FOT)...

BACKGROUND: Exercise is the AHA/ACC guideline-recommended stress modality for myocardial perfusion imaging, but many patients are unable to exercise to target heart rate on a conventional treadmill. We examined the feasibility and safety of stress imaging using an anti-gravity treadmill in patients with perceived poor exercise capacity. METHODS AND RESULTS: 49 patients were recruited for stress testing by anti-gravity treadmill (n = 29) or to a regadenoson control group (n = 20)...

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is an increasingly common cause of death worldwide. Its cardinal symptoms include breathlessness and severely reduced exercise capacity. Several patient-reported outcome (PRO) measures are used to assess health-related quality of life (HRQoL), functional performance, and breathlessness in patients with COPD. Exercise testing is employed to measure functional performance objectively, which is generally believed to impact on overall HRQoL...

Background -Exercise promotes metabolic remodeling in the heart, which is associated with physiologic cardiac growth; however, it is not known whether or how physical activity-induced changes in cardiac metabolism cause myocardial remodeling. In this study, we tested whether exercise-mediated changes in cardiomyocyte glucose metabolism are important for physiologic cardiac growth. Methods -We used radiometric, immunologic, metabolomic, and biochemical assays to measure changes in myocardial glucose metabolism in mice subjected to acute and chronic treadmill exercise...

Abstrato Background: Constraint-induced movement therapy (CIMT) is suggested to reduce functional asymmetry between the upper limbs after stroke. However, there are few studies about CIMT for lower limbs. OBJECTIVE: To examine the effects of CIMT for lower limbs on functional mobility and postural balance in subjects with stroke. METHODS: A 40-day follow-up, single-blind randomized controlled trial was performed with 38 subacute stroke patients (mean of 4.5 months post-stroke)...

BACKGROUND: Fewer than half of individuals with peripheral artery disease (PAD) experience classic claudication, and the relationships between PAD typical or atypical symptom intensity, location, and description (classic or atypical) with ischemic changes have not previously been reported. OBJECTIVE: The primary purpose of this study was to evaluate the relationship between self-reported PAD symptom intensity and calf tissue ischemia measured using the tissue saturation index (TSI) during treadmill exercise...
