The molecular basis of idiopathic generalized epilepsy remains poorly understood. Absence epilepsy with 3 Hz spike-wave EEG is one of the most common human epilepsies, and is associated with significant morbidity. Several spontaneously occurring genetic mouse models of absence epilepsy are caused by dysfunction of the P/Q-type voltage-gated calcium channel(More)
Ratings of perceived exertion (RPE) are commonly used to monitor the intensity of aerobic exercise. Whether ratings of perceived exertion can be used similarly during resistance exercise is unclear. To examine this question, perceived exertion was measured at 30% and 90% of the one-repetition maximum (1-RM), while holding work constant between intensities.(More)
The purpose of this project was to determine the validity of standardized Borg scale instructions and scale anchoring procedures to measure active muscle rating of perceived exertion and overall rating of perceived exertion during resistance exercise. Anchoring procedures were determined for each of 7 exercises before the completion of 2 counterbalanced(More)
This investigation developed statistical models to estimate one repetition maximum (1 RM) muscular strength using submaximal ratings of perceived exertion (RPE) as predictor variables. Ten- to 14-year-old girls (n = 35) and boys (n = 35) performed two sets (10 repetitions) of biceps curl (BC) and knee extension (KE) exercise using weights approximating 30%(More)
BACKGROUND The ability to generate maximal muscular force is dependent upon time mediated mechanisms of fatigue. Interset rest interval length may not only affect force production but may also manifest changes in ratings of perceived exertion (RPE). The purpose of this study was to examine the effects of rest interval on quadriceps torque and RPE during(More)
The cooperatively breeding bell miner, Manorina melanophrys, differs from most other cooperative breeding species in the complexity of its social system, where discrete social organization occurs on at least three levels. Microsatellite markers were used to investigate the degree of genetic structure underlying the social organization of M. melanophrys by(More)
The purpose of this study was to explore the effects of a 7-week heavy elastic band and weighted-chain program on maximum muscular strength and maximum power in the bench press exercise. Thirty-six (n = 36) healthy men aged 18-30 years old, from the Robert Morris University football team, volunteered to participate in this study. During the first week,(More)
PURPOSE The stepping pictorial format of the Children's OMNI Perceived Exertion Scale (0-10) was validated for female (N = 20) and male (N = 20) children, 8-12 yr old with a peak (step) oxygen consumption of 46.1 +/- 5.3 mL.kg(-1).min(-1). METHODS Ratings of perceived exertion for the overall body (RPE-O), legs (RPE-L), and chest (RPE-C) were determined(More)
This investigation analyzed the effect of rest interval length on the rating of perceived exertion (RPE) during a resistance exercise session. Nineteen males performed two experimental sessions: resistance exercise with 30-sec. rest intervals (E30) and 90-sec. rest intervals (E90). In both sessions, five exercises (bench press, knee extension, seated row,(More)
The purpose of this review is to examine the evidence that links specific physiological processes with central signals of perceived exertion during dynamic exercise. The physiological processes thought to be associated with a central signals of exertion include heart rate (HR), ventilation (VE), respiratory rate (RR), and oxygen uptake (VO2). Parallel(More)
