Background There is a lack of research considering acute fatigue responses to high- and low-load resistance training as well as the comparison between male and female responses. Furthermore, limited studies have considered fatigue response testing with the inclusion of perceptions of discomfort and exertion. Methods The present study included males (n = 9; 23.8 ± 6.4 years; 176.7 ± 6.2 cm; 73...

This study investigated the effect of different repetition durations on ratings of perceived exertion (RPE) in active muscles (RPE-AM) and the overall body (RPE-O). 19 male volunteers (M age = 25.4 yr., SD = 3.5) performed strength training protocols with multiple sets matched by the number of sets and repetitions, intensity and rest interval but different repetition durations: 4 sec., 6 sec., ...

Subjective estimates of physical work intensity are considered of major importance to those concerned with prescription of exercise. This article reviews major theoretical models which might guide research on the antecedents for ratings of perceived exertion (RPE). It is argued that an active rather than passive view of perception is warranted in future research, and a parallel-processing model...

BACKGROUND To examine the role of psychological distress, negative life events, social support and lack of fitness (using breathlessness on exertion as a proxy) in the development of new onset fatigue in a primary care population. METHOD Adults between the ages of 18 and 45 years who were registered with five general practices in South East England were asked to complete a fatigue questionnai...

The purpose of our study was to analyze the effects of upper-body fatigue and lower-body fatigue on post-exercise standing balance. Force plates were used to assess static balance by measuring the displacement of the Center of Pressure (COP) while subjects stood on the plate. Ten healthy male undergraduate students (mean age 20.7 years, SD = 1.3) each participated in one session. All subjects w...

PERCEPTION OF EFFORT, also known as perceived exertion or sense of effort, is a major feature of fatigue (7), and it is widely used to monitor and prescribe exercise intensity (18). However, despite its importance, the neurophysiological bases of this atypical sensation are poorly understood. A model popular among physiologists investigating central regulation of exercise performance is that pe...

Unlike facial expressions of emotion, the effect of static and dynamic facial information on the perception of physical exertion have not been discussed in much depth. The purpose of this study is to examine whether the observer could perceive exertion by others based only on static or dynamic facial expression. And to examine which conditions (static and dynamic exertion face) could be better ...

BACKGROUND Previous research has demonstrated that trained rescuers have difficulties achieving and maintaining the correct depth and rate of chest compressions during both in and out of hospital cardiopulmonary resuscitation (CPR). Feedback on rate and depth mitigate decline in performance quality but not completely with the residual performance decline attributed to rescuer fatigue. The purpo...
