BACKGROUND The leading cause of mortality in on-duty firefighters is sudden cardiac death. While the reason for this remains unclear, low cardiorespiratory fitness and the metabolic syndrome have been associated with increased risk of cardiovascular disease-related events. AIMS To document the levels of cardiorespiratory fitness and the metabolic syndrome, as well as to determine if there is ...

OBJECTIVE To analyze the association and agreement of fitnessgram reference criteria (RC) for cardiorespiratory fitness, body mass index (BMI) and strength in youth. METHODS The study included 781 youth, 386 females, aged 10 to 18 years of Londrina-PR. It were performed cardiorespiratory fitness and muscular strength tests and was calculated body mass index. The association between the tests ...

BACKGROUND Prevalence of cardiovascular risk factors is unevenly distributed among occupational groups. The working environment, as well as lifestyle and socioeconomic status contribute to the disparity and variation in prevalence of these risk factors. High physical work demands have been shown to increase the risk for cardiovascular disease and mortality, contrary to leisure time physical act...

T he authors evaluated whether the effects of cardiorespiratory fitness and adiposity jointly are related to mortality in hypertensive men.1 They found that the effect of cardiorespiratory fitness is a powerful modifier of the association between adiposity and mortality in men with hypertension. It has been shown, in a well-known long-term prospective study in a general population, that cardior...

Regular exercise training improves insulin sensitivity and blood glucose control in subjects with type 2 diabetes [1] and is considered a key element in the management of this condition [2]. Furthermore, regular exercise in these subjects offers a number of additional benefits, such as improved body composition with increased skeletal muscle mass and decreased fat mass, especially ectopic and a...

The literature examining the relationship between cardiorespiratory fitness and the brain in older adults has increased rapidly, with 30 of 34 studies published since 2008. Here we review cross-sectional and exercise intervention studies in older adults examining the relationship between cardiorespiratory fitness and brain structure and function, typically assessed using Magnetic Resonance Imag...

BACKGROUND We tested the hypothesis that higher levels of cardiorespiratory fitness are inversely associated with carotid artery intima media thickness in 746 (age 53 ± 7 yrs) men with type 2 diabetes. METHODS We measured common carotid intima media thickness and defined carotid atherosclerosis as a carotid intima media thickness > 1.0 mm. Cardiorespiratory fitness was directly measured by pe...

(i) In 2.2. Clinical Evaluation. Shimamoto et al. [3] studied seasonal variations in body composition and anthropometric characteristics during a weight loss program. The aim of our study was to examine cardiorespiratory parameters at IVT and peak exercise capacity, and it was not to evaluate the effects of a weight loss program on body composition in obese subjects. However, the season (Januar...

BACKGROUND Epidemiologic studies have reported that cardiorespiratory fitness is inversely associated with mortality from cancer. However, the evidence relating cardiorespiratory fitness to cancer mortality has not yet been quantitatively summarized. METHODS Following the preferred reporting items for sytematic reviews and meta-analyses (PRISMA) checklist, we conducted a systematic review and...
