Acute and Chronic Effects of Artificial Rearing on Rat Genioglossus Muscle
… P14 and P42. At P14 maximum tetanic tension and fatigue index were lower in the AR group than the DR group and no differences were found in MHC distribution. By day 42, AR rats had a higher fatigue index that DR rats and DR rats had a higher percentage of MHCIIa than AR rats. The artificial …

Effect of Honey on Anaerobic Performance in Male Collegiate Soccer Players
… looking at maximum, minimum, and mean power, and fatigue index. Immediately following the RAST, subjects answered questions about gastrointestinal distress, and rated their perceived exertion. Pre-test carbohydrate ingestion showed no significant effect on maximum, minimum, or mean power, fatigue …

The Effects of a Combined Supplementation of Creatine and Sodium Bicarbonate on Repeated Sprint Performance
… peak power, RPP, mean power, RMP, fatigue index, and perceptions of fatigue and GI distress were assessed during six 10-second repeated Wingate tests. Blood bicarbonate, pH, and lactate were measured 5 minutes before testing and immediately after the last Wingate sprint. The main …

The effect of trunk stability and leg strength training on vertical take-off velocity in athletes
… take-off velocity using a force plate and fatigue index using a repeated vertical jump test. Pre-training take-off velocity and pre-training body mass were used as co variates. After three weeks of training, only the TS group had a significantly greater vertical take-off velocity compared …

Factors related to cycling performance
… threshold (AT) velocity, 4mM AT velocity, fatigue index, peak blood lactate, and anaerobic work capacity. Participants were USCF 30 category 1 through 5 cyclists. Participants performed one 20.75 km and two 10.37 km all-out tests in the field. They also performed an incremental test. The …

Determining optimal load for a constant-load cycle ergometer test relative to isotonic leg strength
… power (PP), time to peak power (TTPP), power fatigue rate (PFR), power fatigue index (PFI), and average power (AP). These values were collected by a microcomputer interfaced with the cycle ergometer. In general, PP decreased at a resistance greater than 9 % 1RM. The average reported PP values …

Vocal Fatigue in Collegiate Singers: An Exploratory Investigation Towards a New Assessment Protocol
… and one from a non-singing context (The Vocal Fatigue Index: VFI) with the intent of identifying the most effective means to monitor the vocal status of collegiate singers. Participants (N = 123) completed a survey that included the VFI, EASE, perceptual evaluations of each protocol, and other …

The effect of rapid dehydration on repeated bouts of short-term, high-intensity cycling exercise in college wrestlers
… power (AP,W), time to peak power (TTPP,s), power fatigue rate (PFR,W/s), and power fatigue index (PFI,%) were recorded by an integrated microcomputer. Pretrial plasma osmolality (PO), HTC, plasma electrolytes, and caloric intake (Kcal) were also measured. The wrestlers lost 4.5±1.0% (X±SD) …

The effects of a high-carbohydrate, low-fat diet versus a low-carbohydrate, high-fat diet on dancer's performance
… diet for approximately one month. A Perceived Fatigue Assessment, dual energy x-ray absorptiometry, and exercise testing including a 30 second Wingate, lateral raises, calf raises, push-ups, and 90-second box jumps were performed at pre- and post-assessment for both diets. HRV was measured …

Effectiveness of sleep extension on athletic performance and nutrition of female track athletes
… 713.5 +/- 214.6 watts) and slight decrements in fatigue index from baseline (37.3 +/- 10.6% versus 38.8 +/- 8.42%), however these were not significant (p = 0.07, p = 0.28 respectively). Mean PVT scores remained unchanged (p = 0.98) and POMS scores significantly decreased (p = 0.01) following more …

Optimisation considerations for the measurement of human muscle power
… Peak mechanical power, mean mechanical power, fatigue index and total mechanical work values were calculated for each subject during each test, and the sample mean differences associated with the two protocols were compared using paired Student t-tests. The with - grip protocol yielded …

Effects of emphysema and chronic hypoxemia on skeletal muscle oxygen supply and demand
… included peak force, force-time integral, and fatigue index. Due to a presumed rat respiratory virus, which likely resulted in the control group being nearly as hypoxemic as the elastase-induced emphysema group, this study was not able to definitively test the hypothesis that chronic hypoxemia …

Dysphoria, Fatigue, and Sleep in Employed Postpartum Women
… health status. The symptoms of dysphoric mood, fatigue, and sleep disturbances have been recognized as reasons for which postpartum women seek health care services. Yet, unless the symptom experience is clinically significant, few interventions are offered. The recognition that causal …

Quantification of muscle fatigue in cerebal palsy and its relationship to impairments and function
… designed to explore the measurement of muscle fatigue in people with cerebral palsy (CP). The four aims were to 1) develop a feasible and reliable isokinetic protocol to assess muscle fatigue of the knee flexors and extensors in this population, 2) determine if muscle fatigue of the knee …

The Longitudinal Effects of Beta-Alanine on Punch Power, Punch Frequency, and Fatigue in Female Amateur Fighters
… of BA on punch power, punch frequency, fatigue, and lactate accumulation in female amateur fighters. Twelve females (age = 23.25 ± 3.84) with at least three months of training volunteered to participate in this randomized double-blind study. Each participant was supplemented with either …

Relationships between sprint performance, power output and fatigue
… power (AP), time to peak power (TTPP), power fatigue rate (PFR), and power fatigue index (PFI) were computed using a microcomputer system. In addition, PP,AP, and PFR were adjusted for total bodyweight (PP/kg, AP/kg, PFR/kg). On a separate day each subject performed six sprints two each at …
