OBJECTIVE To evaluate pulse pressure changes according to duration of type 1 diabetes and to assess the influence of posture. RESEARCH DESIGN AND METHODS We performed continuous measurement of blood pressure with a Finapres device during a 3 x 1 min posture test (standing, squatting, standing) in 159 type 1 diabetic patients divided into four groups according to diabetes duration (<or=10, 11-...

In certain disease states prolongation of the QT interval has been shown to be arrhythmogenic. Whether QTc interval changes with position and thus whether certain positions are more arrhythmogenic than others is not known for different diseases that predispose to arrhythmias, and was therefore studied. Patients with left ventricular hypertrophy and heart failure, and the appropriate matched con...

Squat jump (SJ) has been extensively used in training, yet analysis in trained athletes is scarce. Therefore, main research question was: what strength parameters can better explain the best SJ performance in trained athletes? Thirty five athletes performed 3 maximal SJ (using a 17kg bar) weighted jumps while ground reaction forces were sampled using a force platform synchronized with a linear ...

Poor working postures and task demands are common factors that affect human performance in a workplace , particularly in the industrial sector (i.e., assembly tasks). These factors can lead to performance deterioration and introduce musculoskeletal disorders (MSDs). The current research study examines the interaction effects of working postures and assembly task demands on human performance and...

PURPOSE To determine whether nifedipine, an L-type calcium channel blocker, alters choroidal blood flow (ChBF) regulation during isometric exercise in healthy subjects. METHODS The study was carried out in a randomized, placebo-controlled, double-masked, two-way crossover design. Fifteen healthy male subjects were randomly assigned to receive either placebo or nifedipine on two different stud...

OBJECTIVE To analyze relationships between physical occupational exposures, post-retirement shoulder/knee pain, and obesity. METHODS 9 415 male participants (aged 63-73 in 2012) from the French GAZEL cohort answered self-administered questionnaires in 2006 and 2012. Occupational exposures retrospectively assessed in 2006 included arm elevation and squatting (never, <10 years, ≥10 years). "Sev...
