AIM To investigate the test-retest reproducibility of the Muscle Power Sprint Test (MPST), the 10 × 5-m sprint test, and the arm-cranking Wingate Anaerobic Test (WAnT) in children and adolescents with cerebral palsy (CP). A secondary objective was to assess the construct validity of the MPST. METHOD Twenty-three participants with spastic CP (mean age 13 y 3 mo, range 7-18 y, SD 3.6 y; 18 male...

the aim of this study was to study the effects of two fitness training programs with long and short sets with the same intensity and volume on physical fitness and performance factors in rugby elite players. 27 rugby players from rugby club of khorasan razavi gas industrial cooperative (age 24.29+3.172 yr and height 182.22+5.652 cm) participated voluntarily and were divided randomly into three ...

Objective: To explore the anaerobic power and surface EMG (sEMG) of quardrocep muscle in lower extremities after single vibration training intervention. Methods: 8 excellent male long jumpers voluntarily participated in this study. Four intervention modes were devised, including high frequency high amplitude (HFHA,30Hz,6mm), low frequency low amplitude(LFLA,15Hz,3mm), high frequency low amplitu...

Workout capacity is energy-production driven. To produce peak metabolic power outputs, the organism predominantly relies more on anaerobic metabolism, but this undoubtedly has a negative and limiting impact on muscle function and performance. The aim of the study was to evaluate if an innovative polyphenol-based food supplement, PerfLoad®, was able to improve metabolic homeostasis and physical ...

Purpose: This study evaluated the test-retest reliability of the Wingate Anaerobic Test (WAnT) performed on a Velotron electromagnetically-braked cycle ergometer (EE) for powertrained athletes and assessed whether a familiarization trial was necessary to achieve high test-retest reliability. Methods: Twentyone male ice hockey players (age 23.5 ± 4.7 yrs, mass 86.3 ± 16.6 kg, height 180.9 ± 7.4 ...

Simultaneous anaerobic and aerobic degradation pathways in two-chamber, tubular microbial fuel cells (MFCs) facilitated pentachlorophenol (PCP) mineralization by a mediator-less biocathode. PCP was degraded at a rate of 0.263 ± 0.05 mg/L-h (51.5 mg/g VSS-h) along with power generation of 2.5 ± 0.03 W/m(3). Operating the biocathode MFC at 50°C improved the PCP degradation rate to 0.523 ± 0.08 mg...

PURPOSE This study examined the effects of hypohydration and moderate hyperthermia (core temperature elevation) on anaerobic exercise performance in a temperate environment. METHODS Eight active males completed two passive heat exposure trials (180 min, 45 degrees C, 50% rh) with (EUH) and without (HYP) fluid replacement. A single 15-s Wingate anaerobic test (WAnT) was used to assess anaerobi...

Although the contribution of anaerobic power to soccer performance has been widely recognized, this parameter of physical fitness has not been well studied in young players. The aim of this study was to investigate the force-velocity (F-v) components of anaerobic power across adolescence. Male adolescent players (N=561; aged 10–22 years), classified into six two-year age groups, all members of ...

Lignocellulosic material can be used as biomass for power generation via biogas if it is pretreated to improve the anaerobic hydrolysis step, by either solubilising the hemicellulose (total reducing groups, TRG) or removing lignin (Lig), with consequent exposition of the cellulose fibre to anaerobic degradation. We evaluated the effects of acid, alkaline, and hydrothermal pretreatments on sugar...
