—The purpose of this study was to assess whether a treadmill mile is an acceptable FitnessGram® Test substitute for the traditional one-mile run for middle school boys and girls. Peak heart rate and perceived physical exertion of the participants were also measured to assess students’ eff ort. 48 boys and 40 girls participated, with approximately 85% classifi ed as Hispanic. Boys’ mean time for...

Though the development of physical limitations associated with neuromuscular disease is often apparent to the clinician, the development of neuromuscular-induced respiratory muscle weakness can be insidious. Respiratory muscle weakness is often overlooked by the clinician, particularly when weakness of the extremities limits physical exertion and no respiratory compensation for exertion is requ...

[Purpose] The aim of this study was to observe the relationships among heart rate, rate of perceived exertion, and oxygen consumption in stroke patients and the effectiveness of improving aerobic capacity during routine rehabilitation therapy. [Subjects and Methods] Thirty-six stroke patients participated in the study. A K4b(2) pulmonary function device was used to record heart rate (beats per ...

The aim of this study was to investigate the heart rate (HR) responses, the rate of perceived exertion (RPE), and the feeling during physical education schooling while performing traditional games activities compared to intermittent exercise. Nineteen pre-pubertal children randomly performed on different days two types of lessons (intermittent running mode vs. traditional Tunisian "Raqassa" gam...

Research shows that self-control is resource limited and there is a gradual weakening in consecutive self-control task performance akin to muscle fatigue. A body of evidence suggests that the resource is glucose and consuming glucose reduces this effect. This study examined the effect of glucose on performance in the antisaccade task - which requires self-control through generating a voluntary ...

Loading/unloading a ladder on vehicles are frequent tasks and involve overhead handling that may expose workers to risk factors of shoulder musculoskeletal disorders. The objective of the present study was to evaluate posture, forces required and perceived exertion when loading and unloading the ladder on a utility truck. Thirteen male overhead line workers from an electric utility in Brazil pa...

OBJECTIVE The aim of this study was to evaluate the role of urodynamic test in diagnosis of urinary incontinence, comparing detailed data of history and physical examination, and some easy- to-apply clinical tests. METHODS A cross-sectional retrospective study was carried out by reviewing the medical charts of 55 patients with complaint of loss of urine, seen at the Urogynecology Service of W...

Taylor, Derek V., James G. Boyajian, Norman James, Danette Woods, Aleksandra Chicz-Demet, Archie F. Wilson, and Curt A. Sandman. Acidosis stimulates P-endorphin release during exercise. J. Appl. Physiol. 77(4): 1913-1918, 1994.-Elevated blood levels of /3-endorphin have been associated with high-intensity exertion, but the stimulus for P-endorphin release is unknown. Some studies of exercise ha...

This study used a computer-controlled electric right angle nutrunner to investigate the relative effects of different power hand tool and process parameters on operator muscular exertions, handle stability and subjective ratings of perceived exertion. Target torque (25, 40 and 55 Nm), torque build-up time (35, 150, 300, 500 and 900 ms), and workstation orientation (horizontal and vertical) were...

It is important to develop an accurate method of measuring controlled force exertion. This study examined the age differences between the controlled force exertion measured by a sinusoidal waveform and a bar chart display. The participants comprised 175 right-handed male adults aged 20–86 years. The participants were divided into three age groups: young (n = 53), middle-aged (n = 71), and elder...
