BACKGROUND Oral tobacco (snuff) is taking a large market share in Scandinavia, especially with young users. However, long-term health effects are unknown. Small studies show association between snuff and reduced endothelial function, representing an early stage of vascular injury that often precedes manifest cardiovascular disease by several years. We therefore determined the associations betwe...

The present study is the first to investigate whether cerebral blood flow in the hippocampus relates to aerobic fitness in children. In particular, we used arterial spin labeling (ASL) perfusion MRI to provide a quantitative measure of blood flow in the hippocampus in 73 7- to 9-year-old preadolescent children. Indeed, aerobic fitness was found to relate to greater perfusion in the hippocampus,...

BACKGROUND Cardiorespiratory fitness is low after stroke. Improving fitness has the potential to improve function and reduce secondary cardiovascular events. OBJECTIVE . This review with meta-analysis aims to identify characteristics and determine the effectiveness of interventions to improve cardiorespiratory fitness after stroke. METHODS A systematic search and review with meta-analysis w...

BACKGROUND Health-related and disease-specific quality of life (HRQoL) has been increasingly valued as relevant clinical parameter in cystic fibrosis (CF) clinical care and clinical trials. HRQoL measures should assess - among other domains - daily functioning from a patient's perspective. However, validation studies for the most frequently used HRQoL questionnaire in CF, the Cystic Fibrosis Qu...

This study assessed the relationship between cardiovascular fitness and temporal preparation in elderly persons. 110 older adults (aged 60-69 or 70-79 years) were sorted into low- and high-fit groups based on aerobic fitness level estimated with a walking test. Response preparation processes were assessed with reaction time tasks in which short (1, 3, 5 s) and long (5, 7, 9 s) preparatory inter...

In humans, the strong statistical association between fitness and survival suggests a link between impaired oxygen metabolism and disease. We hypothesized that artificial selection of rats based on low and high intrinsic exercise capacity would yield models that also contrast for disease risk. After 11 generations, rats with low aerobic capacity scored high on cardiovascular risk factors that c...

Background. Archery is a sport that demands a high level of fitness due to its long hours of training and competitive nature. Thus, archers need to have high fatigue tolerance and body figure to perform successfully. Objectives. This study aims to compare and correlate the anthropometric and physical fitness variables on archery shooting performance. Methods. Participants were youth archers o...

The aim of this study was to address the question if the VO2 kinetics is further improved as the aerobic training status increases from trained to elite level athletes. Maximal oxygen uptake (VO2max), work-rate associated to VO2max (IVO2max) and VO2 kinetics of moderate (Mod) and maximal exercise (Max) were determined in fifty- five subjects. Then, they were assigned into three groups: low (LF)...

BACKGROUND Stress fractures account for substantial morbidity for young women undergoing U.S. Marine Corps basic training. HYPOTHESIS Certain pretraining characteristics identify women at increased risk of stress fractures during boot camp. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS Data collected included baseline performance on a timed run (a measure of aerobic fitness), a...

purpose the present study was designed to evaluate the effects of aerobic and strength training on cardiac variables such as blood pressure, heart rate (hr), and metabolic parameters like cholesterol, high density lipoprotein (hdl), triglycerides and anthropometric parameters of obese women of punjab. methods this study was performed as an experimental study, in which subjects were randomly sel...
