#Caffeine increases maximal #fat oxidation during a graded exercise test: is there a diurnal variation?

There is evidence that caffeine increases the maximal fat oxidation rate (MFO) and aerobic capacity, which are known to be lower in the morning than in the afternoon. This paper examines the effect of caffeine intake on the diurnal variation of MFO during a graded exercise test in active men. Methods Using a triple-blind, placebo-controlled, crossover experimental design, 15 active caffeine-naïve men (age: 32 ± 7 years) completed … Continue reading #Caffeine increases maximal #fat oxidation during a graded exercise test: is there a diurnal variation?

OR10-1 – Efficacy of High-Intensity Intermittent #Training for Improving Cardio-Metabolic Health in Women With #Polycystic Ovary Syndrome

Polycystic ovary syndrome (PCOS) is a common and complex endocrinopathy with significant metabolic and reproductive manifestations, carrying a major health and economic burden. Consistent improvements in clinical outcomes have been reported as a result of exercise training, but shortfalls with exercise prescription are evident. Research suggests that high-intensity intermittent training (HIIT) is feasible, well tolerated and enjoyable for people with or at risk of chronic … Continue reading OR10-1 – Efficacy of High-Intensity Intermittent #Training for Improving Cardio-Metabolic Health in Women With #Polycystic Ovary Syndrome

#Physical activity may not be associated with long‐term risk of #dementia and #Alzheimer’s disease

While it is well established that physical activity is associated with reduced risk of vascular and nonvascular outcomes as well as mortality, evidence on the association between physical activity and dementia is inconsistent. We aimed to assess the associations of physical activity with the risk of dementia and Alzheimer’s disease (AD). Material and methods We analysed data on 2394 apparently healthy men with good baseline … Continue reading #Physical activity may not be associated with long‐term risk of #dementia and #Alzheimer’s disease

#Pain and fatigue are longitudinally and bi-directionally associated with more #sedentary time and less standing time in #rheumatoid arthritis

The aims of this study were to examine the longitudinal and bi-directional associations of pain and fatigue with sedentary, standing and stepping time in RA. Methods People living with RA undertook identical assessments at baseline (T1, n = 104) and 6-month follow-up (T2, n = 54). Participants completed physical measures (e.g. height, weight, BMI) and routine clinical assessments to characterize RA disease activity (DAS-28). Participants also completed questionnaires to … Continue reading #Pain and fatigue are longitudinally and bi-directionally associated with more #sedentary time and less standing time in #rheumatoid arthritis

Effect of High-Intensity Strength #Training on #Knee Pain and Knee Joint Compressive Forces Among Adults With Knee #Osteoarthritis

Thigh muscle weakness is associated with knee discomfort and osteoarthritis disease progression. Little is known about the efficacy of high-intensity strength training in patients with knee osteoarthritis or whether it may worsen knee symptoms. Objective To determine whether high-intensity strength training reduces knee pain and knee joint compressive forces more than low-intensity strength training and more than attention control in patients with knee osteoarthritis. Design, … Continue reading Effect of High-Intensity Strength #Training on #Knee Pain and Knee Joint Compressive Forces Among Adults With Knee #Osteoarthritis

Long-term risk of #stroke and myocardial #infarction in middle-aged men with a #hypertensive response to exercise: a 44-year follow-up study

Data on the prognostic value of hypertensive response to exercise in cardiovascular disease are limited. The aim was to determine whether SBP reactions during exercise have any prognostic value in relation to the long-term risk of stroke and myocardial infarction (MI). Patients and methods: A representative cohort of men from Gothenburg, Sweden, born in 1913, who performed a maximum exercise test at age 54 years, … Continue reading Long-term risk of #stroke and myocardial #infarction in middle-aged men with a #hypertensive response to exercise: a 44-year follow-up study

Longitudinal Associations of Midlife Accelerometer Determined #Sedentary Behavior and Physical Activity With #Cognitive Function: The CARDIA Study

To determine if accelerometer measured sedentary behavior (SED), light‐intensity physical activity (LPA), and moderate‐to‐vigorous–intensity physical activity (MVPA) in midlife is prospectively associated with cognitive function. Participants were 1970 adults enrolled in the CARDIA (Coronary Artery Risk Development in Young Adults) study who wore an accelerometer in 2005 to 2006 (ages 38–50 years) and had cognitive function assessments completed 5 and/or 10 years later. SED, LPA, … Continue reading Longitudinal Associations of Midlife Accelerometer Determined #Sedentary Behavior and Physical Activity With #Cognitive Function: The CARDIA Study

Childhood Daily #Energy Expenditure Does Not Decrease with Market Integration and Is Not Related to #Adiposity in Amazonia

Childhood overweight and obesity (OW/OB) is increasingly centered in low- and middle-income countries (LMICs) as rural populations experience market integration and lifeway change. Most explanatory studies have relied on imprecise estimates of children’s energy expenditure, restricting understanding of the relative effects of changes in diet and energy expenditure on the development of OW/OB in transitioning contexts.. ..Cross-sectional data were collected from “rural” (n = 43) … Continue reading Childhood Daily #Energy Expenditure Does Not Decrease with Market Integration and Is Not Related to #Adiposity in Amazonia

The Effect of Flat Flexible Versus Stable Supportive #Shoes on Knee #Osteoarthritis Symptoms

Experts recommend that persons with knee osteoarthritis wear stable supportive shoes; however, evidence suggests that flat flexible shoes may be more beneficial.. ..Of 164 participants recruited, 161 (98%) completed 6-month primary outcomes. No evidence was found that flat flexible shoes were superior to stable supportive shoes in primary outcomes. Evidence did show a between-group difference in change in pain favoring stable supportive shoes (mean difference, … Continue reading The Effect of Flat Flexible Versus Stable Supportive #Shoes on Knee #Osteoarthritis Symptoms

#Cardiac Structure and Function in Elite Female and Male #Soccer Players

Population-specific normative data are essential for the evaluation of competitive athletes. At present, there are limited data defining normal electrocardiographic (ECG) and echocardiographic values among elite US soccer players.. .. A total of 238 athletes (122 [51%] female; mean [SD] age, 20 [4] years; age range, 15-40 years) were included. Male athletes demonstrated a higher prevalence of normal training-related ECG findings, while female athletes were more likely … Continue reading #Cardiac Structure and Function in Elite Female and Male #Soccer Players

The global epidemiology of #hypertension

Hypertension is the leading cause of cardiovascular disease and premature death worldwide. Owing to the widespread use of antihypertensive medications, global mean blood pressure (BP) has remained constant or has decreased slightly over the past four decades. By contrast, the prevalence of hypertension has increased, especially in low- and middle-income countries (LMICs). Estimates suggest that 31.1% of adults (1.39 billion) worldwide had hypertension in 2010. … Continue reading The global epidemiology of #hypertension

#Cardiovascular health metrics from mid- to late-life and risk of #dementia: A population-based cohort study in Finland

Very few studies have explored the patterns of cardiovascular health (CVH) metrics in midlife and late life in relation to risk of dementia. We examined the associations of composite CVH metrics from midlife to late life with risk of incident dementia. This cohort study included 1,449 participants from the Finnish Cardiovascular Risk Factors, Aging, and Dementia (CAIDE) study, who were followed from midlife (baseline from1972 … Continue reading #Cardiovascular health metrics from mid- to late-life and risk of #dementia: A population-based cohort study in Finland
