Background: Energy expenditure is of paramount importance in the assessment of usefulness of wheelchair for paraplegics. Despite widespread recognition of problems associated with currently available mobility systems for persons with spinal cord injuries, development of more efficient systems has been slow.  Lack of a suitable and simple technique for the assessment of energy expenditure in par...

INTRODUCTION The most widely used instrument to measure perceived exertion or exercise intensity is the Borg's Rating of Perceived Exertion (RPE) Scale. Panic attacks are aversive experiences that may be triggered by bodily sensations such as palpitations, breathlessness or dizziness due to increasing autonomic distress, prior sensitisation to panic and fear conditioning. The consequence is cat...

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...

in this study, 10 normal volunteers and 5 sports-trained paraplegics with lesions between t6 and l2 were studied whilst walking with axillary crutches and knee-anlde-foot orthoses. all subjects walked at their preferred speed on a figureof- eight track. normal subjects also walked at slower and faster speeds. oxygen consumption, heart rate and rating of perceived exertion were measured. in norm...

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' effort. 48 boys and 40 girls participated, with approximately 85% classified as Hispanic. Boys' mean time for the...

OBJECTIVE The objective was to investigate effects of dieted weight reduction on walking ability in obese women. METHODS Fifty-seven obese women 44.1 +/- 10.7 years, body mass index 37.1 +/- 3.4 kg x m(-2) performed an indoor walking test. Speed, oxygen consumption and heart rate were measured, perceived exertion and pain graded and oxygen cost calculated. Maximum oxygen uptake (VO2max/kg) wa...

This study assessed whether video self-modeling improves running performance and influences the rate of perceived exertion and heart rate response. Twelve men (M age=26.8 yr., SD=6; M body mass index=22.1 kg.m(-2), SD=1) performed a time to exhaustion running test at 100 percent maximal aerobic velocity while focusing on a video self-modeling loop to synchronize their stride. Compared to the co...

BACKGROUND The aim of this study was to investigate whether perceived exertion, perceived comfort and working technique is associated with the incidence of neck and upper extremity symptoms among professional computer users. METHODS At baseline a self-administered questionnaire was distributed to 853 participants from 46 different work sites (382 men and 471 women) who, at baseline, had been ...
