An Optimal Interset Rest Period For Strength Recovery During A Common Isokinetic Test
… basis, yet there is a lack of consistency in rest period usage among protocols. Purpose: The purpose of this study was to establish an optimal rest period that would allow reproducibility of strength during a common isokinetic strength-test. Methods: Twentyseven healthy college-aged males …

An investigation of the effects of a rest period on simple reaction times of kindergarten children
… study was to investigate the effects of a rest period on kindergartners’ performance in a simple reaction time situation. Effects of sex, class, time of measurement and practice on simple reaction time were also factors investigated in the present study. The sample consisted of 32 children …

Investigation of Fatigue Properties of Superpave HMA at the Virginia Smart Road
… of 1 Hz and 5Hz, and at 10 Hz including rest periods of 0.4sec and 0.9sec were performed for one mixture to explore the impact of frequency and rest periods. Analyses were performed on the strain-life relationships and predicted endurance strain limits for the mixtures. Investigation of …

The Effects of Active Recovery during High Intensity Resistance Training on Lactate Clearance in Collegiate Athletes
… the effects of active recovery during the rest periods of a resistance training session on lactate clearance in varsity collegiate athletes. </p> <p>Methods: Twenty healthy varsity collegiate athletes age 18-22 yr participated in a collegiate strength and conditioning workout session. …

Management and Livestock Performance of Alfalfa-Tall Fescue Mixed Stands
… wire exclosures included defoliation height, rest period, exclosure movement, and month and were evaluated using detailed botanical composition and persistence measurements. Defoliation height, rest period, and month all affected alfalfa-tall fescue competition. Alfalfa was generally more …

Skin conductance and reaction time correlates of learning disability in children
… a simple reaction time task, each preceded by a rest period. The two tasks were methodologically equivalent except that only the latter required an active response. LDs had more rapid decline of basal conductances during rest, more rapid habituation of GSRs during tasks, and slower reaction …

Sex differences in the effects of two-hit stress on the structure and function of rat medial prefrontal cortex
… in mPFC is sex-specific during the post-stress period. To assess whether these changes might give rise to functional changes, I developed a “two-hit stress” paradigm in which rats were exposed to chronic stress, given a no-stress rest period, and then exposed to a novel stress challenge (i.e., a …

Gender Differences in the Relation Between Locus of Control and Physiological Responses
… skin conductance responses during a ten minute rest period and to a tone (an Orienting Response (OR) task). A simple difficulty effect was found on the performance scores across the three levels of difficulty for all subjects. There was an inverse relationship between the I and C scales and the …

Hemodynamic Responses to Isometric Contractions of the Finger Flexor and Leg Extensor Muscle Groups in Men 18-30 and 50-70 Years of Age
… for the twenty-five second pre-exercise rest period and for the forty-five second contraction period. Systolic and diastolic blood pressures were recorded once during the pre-exercise rest period and twice, at twenty second intervals, during the contraction period. All four variables were …

The effect of beta-carotene vitamin E, and vitamin C supplementation upon work capacity during a protocol of arm curl exercise using the Biodex dyanamometer
… C, vitamin E). There was a 28 day washout period between the two supplemental stages. Subjects were tested during each stage for an acute effect (one day of supplementation) and chronic effect (twenty-eight days of supplementation). Testing consisted of seven sets of arm curl exercises with …

Cardiovascular Fitness of Horses Conditioned by Treadmill Work
… In all three experiments, the SET consisted of a rest period and warm-up walk followed by a period of trotting (11.4 to 12.1 kph) and a six minute standing recovery period on the treadmill. Parameters were measured at rest and at the end of both the trot and recovery periods. In the first …

A study of lithographic ink and water interactions
… of the system showed that allowing 'rest periods' between episodes of mixing altered the rate and nature of emulsification. Thus using a modified varnish, rest periods of 1 and 3 minutes produced mean droplet diameters in the range of 1.5-1.8 um whereas rest period of 5 minutes …

A comparison of the standard barbell bench press and novel BandBell bench press
… was tested (115kg ± 21kg) followed by a 4-7 day rest period. A within-subjects design was used and during experimental testing subjects completed eight bench press trials of increasing intensity, and with a variety of loading conditions. Distance travelled of the bar in the sagittal and …

Whole-Body Vibration and Its Effects on Electromechanical Delay and Vertical Jump Performance
… 60 s of WBV in a half-squat followed by 60 s of rest. After 5 intervals, subjects had 6 min of rest before the final 5 intervals. Each subject also participated in the control which included the same 10 intervals in a half-squat without the WBV. Tests were conducted to assess electromechanical …

Effects of mecamylamine on nicotine-induced conditioned hyperactivity and sensitization in differentially reared rats
… training followed by a 16-day drug-free rest period before being tested for sensitization. Mecamylamine (1.0 mg/kg) was administered to rats prior to the conditioned hyperactivity test and sensitization test. Nicotine treatment resulted in sensitization and conditioned hyperactivity in …

Within-Day Reliability of Submaximal Running Economy Testing: Implications for Advanced Footwear Testing
… at their estimated marathon pace (5-minute rest period) during a single visit to the lab. Oxygen consumption (VO2) data were collected during the final two minutes of each stage and averaged in duplicate across stages (A-B-B-A) to replicate the structure of footwear testing. Duplicate …

Heart Rate as a Moderator between Child Abuse Potential and Reactive and Proactive Aggression
… of psychophysiological activity, particularly resting heart rate (HR) and HR variability (HRV), on the relationship between child abuse potential (CAP) and child reactive and proactive aggression. Thirty-six children, between the ages of 7 and 13, and their parents were recruited from the local …

Effect of a Protein-Carbohydrate Beverage on Muscle Damage During an Acute Bout of Concurrent Exercise in Competitively-Training “Crossfit” Men
… (5x5 front barbell squat, 80% 1RM, with 2 min rest), a 15 minute rest period where water or nutritional supplement was consumed, and an aerobic exercise portion (8X10sec maximal sprints, with 45sec rest). Serum measurements were obtained pre AET and immediately post, 30min post, 60min post, and …
