OBJECTIVES To investigate whether bicycling to school improves cardiometabolic risk factor profile and cardiorespiratory fitness among children. DESIGN Prospective, blinded, randomised controlled trial. SETTING Single centre study in Odense, Denmark PARTICIPANTS 43 children previously not bicycling to school were randomly allocated to control group (n=20) (ie, no change in lifestyle) or i...

The peroxisome proliferator-activated receptor gamma 2 (PPARγ2) genotypes are related to obesity and the metabolic syndrome (MetS). A low level of cardiorespiratory fitness is also a strong determining factor in the development of MetS. This cross-sectional study was performed to investigate the influence of the interaction between the PPARγ2 genotype and cardiorespiratory fitness on the risk o...

firefighting is extremely strenuous and physically demanding work and involves ability to cope with emergency life-or-death situations. because of the high physical demands of firefighting, successful job performance and minimizing of morbidity and mortality depends on fitness for duty. the firefighting department of tehran does not perform periodic medical assessment for firefighters. the aim ...

the aim of this study was to evaluate standard and safety indexes in tehran fitness gyms. the population consisted of state and private fitness clubs in tehran.  5 regions of tehran city were selected by cluster sampling method; then, 20 clubs from each region were selected by on non-random convenience sampling method, so a total of 100 fitness clubs were assessed. the aim of this study was app...

OBJECTIVE Up to 30% of obese individuals are metabolically healthy. Metabolically healthy obese (MHO) individuals are characterized by having low abdominal adiposity, low inflammation level and low risk of developing metabolic comorbidity. In this study, we hypothesize that cardiorespiratory fitness (fitness) is a determinant factor for the MHO individuals and aim to investigate the association...

In species where males provide neither direct benefits nor paternal care, it is typically assumed that female preferences are maintained by indirect selection reflecting genetic benefits to offspring of preferred males. However, it remains unclear whether populations harbour sufficient genetic variation in fitness to support costly female preferences - a problem called the 'lek paradox'. Here, ...

Abdominal adiposity and low cardiorespiratory fitness are associated with insulin resistance in people with impaired glucose tolerance and type 2 diabetes. However, little is known about which factor precedes insulin resistance in people with impaired glucose tolerance and type 2 diabetes, and which is the stronger predictor of insulin resistance in non-diabetic people. The purpose of this stud...

conclusions although ceiling effects should be considered for rehabilitation targets, the two-factor model of fim (motor and cognitive independence) has an eligible fitness for iranian patients with tbi. results the results of this study showed that the floor effect was not observed; however, ceiling effects were observed for the fim total score and its subscales. the confirmatory factor analys...
