BACKGROUND Epidemiological findings of higher injury incidence during the latter stages of soccer match-play have been attributed to fatigue. OBJECTIVE To examine the interaction of physical and cognitive responses during soccer-specific intermittent exercise. METHOD Ten semi-professional soccer players completed a 90-minute laboratory-based treadmill protocol replicating the activity profi...

OBJECTIVE Research suggests that one physiological effect of concussion is a disruption in regulation of autonomic nervous system control that affects the balance between parasympathetic and sympathetic output. While changes in heart rate after concussion have been observed, the nature of the heart rate change during progressive exercise has not been well evaluated in acutely symptomatic patien...

[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 ...

Objective. We investigated whether perceived exertion, in comparison to the physiological response to exercise, was associated with self-reported vitality, mental health, and physical function during daily activities, or weight control behaviors. Design. Weight-reduced, formerly overweight women (n = 126, aged 22-46 years), completed health and dietary control questionnaires, and underwent a tr...

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 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...

The objective of this study was to determine the validity and reliability of the EPInfant pediatric perceived exertion rating scale among Chilean children. Children aged 8-12 years old were selected; their heart rate, perceived exertion and workload were recorded during two consecutive Chester tests performed with a one week interval. Pearson's r coefficient and the intraclass correlation coeff...
