Abstract Previous studies examining methods of monitoring the training and match load in soccer players have simply compared those to each other, not changes fitness. Training measures from nine professional youth were collected for a period six weeks. A lactate threshold test was conducted before after this period. Mean weekly as determined by session-RPE, Banister's TRIMP, Team TRIMP individualised (iTRIMP) correlated with percentage velocity at 2 mmol · L−1 (vLT) 4 (vOBLA) blood...
This study aimed to assess the relationships of fitness in soccer players with a novel integration internal and external training load (TL).Ten amateur performed lactate threshold (LT) test followed by simulation (Ball-Sport Endurance Sprint Test [BEAST90mod]).The results from LT were used determine velocity at (vLT), onset blood accumulation (vOBLA), maximal oxygen uptake (VO2max), heart rate-blood profile for calculation TL (individualized impulse, or iTRIMP). The total distance (TD) high...
Bacterial microcompartments (BMCs) are proteinaceous organelles widespread among bacterial phyla. They compartmentalize enzymes within a selectively permeable shell and play important roles in CO2 fixation, pathogenesis, microbial ecology. Here, we combine X-ray crystallography high-speed atomic force microscopy to characterize, at molecular resolution, the structure dynamics of BMC facet assembly. Our results show that preformed hexamers assemble into uniformly oriented layers, single...
Three billion people are exposed to household air pollution from biomass fuel use. Exposure is associated with higher incidence of pneumonia, and possibly tuberculosis. Understanding mechanisms underlying these defects would improve preventive strategies. We used human alveolar macrophages obtained healthy Malawian adults naturally compared them monocyte-derived in vitro respirable-sized particulates. Cellular inflammatory response was assessed by IL-6 IL-8 production particulate challenge;...
Research has demonstrated that induced mental fatigue impairs soccer-specific technical, tactical and physical performance in soccer players. The findings are limited by the lack of elite players low ecological validity tasks used to induce fatigue, which do not resemble cognitive demands soccer. current study collected survey data from English academy (n = 256; age groups - U14 U23), with questions comprising five themes (descriptors travel, education, match-play fixture congestion)....
Cyanobacteria have evolved effective adaptive mechanisms to improve photosynthesis and CO2 fixation. The central CO2-fixing machinery is the carboxysome, which composed of an icosahedral proteinaceous shell encapsulating key carbon fixation enzyme, Rubisco, in interior. Controlled biosynthesis ordered organization carboxysomes are vital activity cyanobacterial cells. However, little known about how carboxysome spatial positioning physiologically regulated adjust dynamic changes environment....
Bacterial microcompartments (BMCs) are proteinaceous self-assembling organelles that widespread among the prokaryotic kingdom. By segmenting key metabolic enzymes and pathways using a polyhedral shell, BMCs play essential roles in carbon assimilation, pathogenesis, microbial ecology. The BMC shell is composed of multiple protein homologs self-assemble to form defined architecture. There tremendous interest engineering develop new nanobioreactors molecular scaffolds. Here, we report...
There has been growing interest in the mechanical behaviour of skin due to rapid development microneedle devices for drug delivery applications into skin. However, most vitro experimentation studies that are used evaluate performance do not consider biomechanical properties or subcutaneous layers. In this study, a representative experimental model was developed which comprised and muscle mimics. Neonatal porcine from abdominal back regions used, with gelatine gels differing water content...
Whilst the movement demands of players completing a whole soccer match have been well-documented, comparable information relating to substitutes is sparse. Therefore, this study profiled match-day physical activities performed by substitutes, focusing separately on pre and post pitch-entry periods. Seventeen English Championship were monitored using 10 Hz Micromechanical Electrical Systems (MEMS) devices during 13 matches in which they participated as (35 observations). Twenty variables...
Introducing reflection anisotropy spectroscopy (RAS) as a new probe for solid-liquid interfaces, we present results the Au(110)/electrolyte interface which serves model system. We demonstrate that RAS is sensitive to surface phase transitions, step morphology, and electronic states. Using an empirical approach, RA spectra are reproduced features identified reflect known character of bias voltage driven (2x1) (1x1) transition. established experimental technique structure interfaces in real...
This study aimed to identify professional soccer practitioners’ perceptions of the application performance analysis technology within a single academy club. Secondary aims were understand importance that practitioners place on monitoring technical and tactical player characteristics, current practices, barriers implementing wearable technology. Utilising mixed method design, forty-four (Age = 32 ± 5.8; Years experience 8.5 6.2) completed an online survey intended examine present trends,...
The aims of this study were to i) compare a foot-mounted inertial system (PlayerMaker™) three commercially available Global Positioning Systems (GPS) for measurement velocity-based metrics during team sport movements and ii) evaluate the inter-unit reliability PlayerMaker™. Twelve soccer players completed simulation, whilst wearing PlayerMaker™ GPS (GPS#1, #2 #3). A sub-sample (n = 7) also wore two systems concurrently. measured higher (p < 0.05) total distance (518 ± 15 m) compared GPS#1...
The structure of the mixed p(3 x 3)-(3OH + 3H2O) phase on Pt[111] has been investigated by low-energy electron diffraction-IV analysis. OH H2O overlayer consists hexagonal rings coplanar oxygen atoms interlinked hydrogen bonds. Lateral shifts O away from atop sites result in different O-O separations and hexagons with only large (2.81 3.02 angstroms) linked alternating 2.49 2.813.02 angstroms. This unusual pattern is consistent a hydrogen-bonded network which water adsorbed cyclic separated...
Diabetes is strongly associated with cardiovascular disease, but the mechanisms, structural and biomechanical consequences of aberrant blood vessel remodelling remain poorly defined. Using an experimental (streptozotocin, STZ) rat model diabetes, we hypothesized that diabetes enhances extracellular protease activity in aorta induces morphological, compositional localized micromechanical tissue remodelling. We found medial aortic layer underwent significant thickening diabetic animals without...
The aim of this study was to examine the effect bio-banding on technical and tactical markers talent identification in 11- 14-year-old academy soccer players.Using a repeated measures design, 92 players were bio-banded using percentage estimated adult stature attainment (week 1), maturity-offset 2) mixed-maturity method 3). All contested five maturity (mis)matched small-sided games with variables measured. Data analysed series Bayesian hierarchical models, fitted different response...
Oral epithelial dysplasia (OED) is a histopathologically-defined, potentially premalignant condition of the oral cavity. The rate transformation to frank carcinoma relatively low (12% within 2 years) and prediction based on histopathological grade unreliable, leading both over- under-treatment. Alternative approaches include infrared (IR) spectroscopy, which able classify cancerous non-cancerous tissue in number cancers, including oral. aim this study was explore capability FTIR...
