Frame Running as a community-based exercise option for young people with moderate-to-severe walking impairments: a feasibility study.

Frame Running is an adapted community-based exercise option for people with moderate-to-severe walking impairments. This mixed-methods study aimed to examine the feasibility of 1) community-based Frame Running by young people with moderate-to-severe walking impairments and 2) conducting future studies on the impact of Frame Running on functional mobility and cardiometabolic disease risk factors. Weekly training sessions and data collection occurred in two sites.

Talent identification and development strategies in elite women's soccer: a pan-European perspective.

The question of how best to identify and develop youth soccer players has received considerable attention from the scientific community. Existing literature has, however, largely focused on male players, with comparatively little exploration of the specific approaches employed within women's soccer. Accordingly, we sought to investigate the key factors deemed important by elite women's soccer clubs concerning the: 1) identification of potential talent; 2) development of players within the player pathway; and 3) selection of players for the next age group or senior team.

Decision-making accuracy of soccer referees in relation to markers of internal and external load.

This study examined the relationships between the decision-making performances of soccer referees and markers of physiological load. Following baseline measurements and habituation procedures, 13 national-level male referees completed a novel Soccer Referee Simulation whilst simultaneously adjudicating on a series of video-based decision-making clips. The correctness of each decision was assessed in relation to the mean heart rate (HR), respiratory rate (RR), minute ventilation (VE), perceptions of breathlessness (RPE-B) and local muscular (RPE-M) exertion and running speeds recorded in the 10-s and 60-s preceding decisions.

Quantifying key parameters related to the life cycle of Caligus rogercresseyi.

The salmon louse Caligus rogercresseyi (Boxshall and Bravo 2000) is a common ectoparasite of farmed salmonids in Chile. Sea lice can negatively impact the growth of hosts, adversely affecting aquaculture productivity. Unlike Lepeophtheirus salmonis (Krøyer, 1838), whose life cycle parameters have been well studied due to its importance in the Northern Hemisphere, for C.

Changes in markers of body composition of professional male soccer players during pre-season.

To evaluate changes achieved in whole-body and regional (upper limbs, lower limbs, and trunk) estimates of body composition, twenty professional male soccer players (7 defenders, 7 midfielders, 6 forwards) underwent dual-energy x-ray absorptiometry (DXA) analysis at the beginning and end of pre-season. Measures included: mass, fat mass (FM), fat-free mass (FFM), and body fat per cent (BF%). Players' activity during on-field training sessions was monitored using Global Positioning System (GPS) units, with GPS data used to obtain estimations of energy expenditure (EE).

Correlational data concerning body centre of mass acceleration, muscle activity, and forces exerted during a suspended lunge under different stability conditions in high-standard track and field athletes.

This article reports data concerning the body centre of mass acceleration, muscle activity, and forces exerted during a suspended lunge under different stability conditions. Ten high-standard track and field athletes were recruited to perform one set of 5 repetitions of the following exercises: suspended lunge, suspended lunge-Foam (front leg on a foam balance-pad and the rear leg on the suspension cradles), a suspended lunge-BOSU up (dome side up), and a suspended lunge-BOSU down (dome side down). For each exercise trial, the acceleration of the body centre of mass (tri-axial accelerometer BIOPAC), the muscle activity of the front leg (surface electromyography BIOPAC) and the force exerted on the suspension strap (load cell Phidgets) were measured.

Modelling sea lice control by lumpfish on Atlantic salmon farms: interactions with mate limitation, temperature and treatment rules.

Atlantic salmon farming is one of the largest aquaculture sectors in the world. A major impact on farm economics, fish welfare and, potentially, nearby wild salmonid populations, is the sea louse ectoparasite Lepeophtheirus salmonis. Sea louse infestations are most often controlled through application of chemicals, but in most farming regions, sea lice have evolved resistance to the small set of available chemicals.

Recruiting Older Men to Walking Football: A Pilot Feasibility Study.

Context: Walking football (soccer) has recently emerged as a physical activity option targeted at older males to enhance health and wellbeing.

Design: This pilot study aimed to examine the feasibility of recruiting and retaining males aged 50 years and over to an 8-week walking football programme in a professional football club.

Intervention: Participants were recruited via social media and assigned to an intervention group or a wait-list control group.

Tool for predicting Caligus rogercresseyi abundance on salt water salmon farms in Chile.

Caligus rogercresseyi is a host-dependent parasite that affects rainbow trout and Atlantic salmon in Chile. Numbers of sea lice on fish increase over time at relatively predictable rates when the environment is conducive to the parasite's survival and fish are not undergoing treatment. We developed a tool for the salmon industry in Chile that predicts the abundance of adult sea lice over time on farms that are relatively isolated.

Interval running with self-selected recovery: Physiology, performance, and perception.

This study (1) compared the physiological responses and performance during a high-intensity interval training (HIIT) session incorporating externally regulated (ER) and self-selected (SS) recovery periods and (2) examined the psychophysiological cues underpinning SS recovery durations. Following an incremental maximal exercise test to determine maximal aerobic speed (MAS), 14 recreationally active males completed 2 HIIT sessions on a non-motorised treadmill. Participants performed 12 × 30 s running intervals at a target intensity of 105% MAS interspersed with 30 s (ER) or SS recovery periods.

Managing aquatic parasites for reduced drug resistance: lessons from the land.

Atlantic salmon farming is one of the largest aquaculture industries in the world. A major problem in salmon farms is the sea louse ectoparasite Lepeophtheirus salmonis, which can cause stress, secondary infection and sometimes mortality in the salmon host. Sea lice have substantial impacts on farm economics and potentially nearby wild salmonid populations.

Using Agent-Based Modelling to Predict the Role of Wild Refugia in the Evolution of Resistance of Sea Lice to Chemotherapeutants.

A major challenge for Atlantic salmon farming in the northern hemisphere is infestation by the sea louse parasite Lepeophtheirus salmonis. The most frequent method of controlling these sea louse infestations is through the use of chemical treatments. However, most major salmon farming areas have observed resistance to common chemotherapeutants.

Toxicity of environmental lead and the influence of intestinal absorption in children.

Exposure to metals, particularly lead, remains a widespread issue that is associated with historical and current industrial practices. Whereas the toxic properties of metals are well described, exposure to metals per se is only one of many factors contributing to elevated blood metal concentrations and their consequent health effects in humans. The absorbed dose of metal is affected by geochemical, biochemical, and physiological parameters that influence the rate and extent of absorption.

Transepithelial resistance and inulin permeability as endpoints in in vitro nephrotoxicity testing.

Transepithelial electrical resistance (RT) and the flux of fluorescein isothiocyanate (FITC) across Madin Darby canine kidney (MDCK) strain 1 cells and porcine epithelial kidney (LLC-PK1) monolayers were compared between three laboratories for a range of nephrotoxins. The precision of the REMS AutoSampler was similar to that of the Ussing chamber and the ENDOHM technique, but superior to using chopstick electrodes, for measurements of resistance. The nephrotoxins used were selective for the proximal tubule, and in all cases, LLC-PK1 cells were more sensitive than MDCK cells.

Absorptive apical amiloride-sensitive Na+ conductance in human endometrial epithelium.

1. Human endometrial epithelial cells cultured on porous tissue culture supports formed tight, polarized epithelial monolayers with features characteristic of tight epithelia.

Co-culture of two MDCK strains with distinct junctional protein expression: a model for intercellular junction rearrangement and cell sorting.

Distinct epithelial MDCK cell strains displaying extremes in transepithelial electrical resistance (paracellular permeability) have been established in co-culture and the subsequent cellular behaviour and formation of junctional complexes investigated. After high-density seeding, MDCK strain I and II cells in co-culture are initially randomly distributed but subsequently sort themselves out in a time-dependent manner to form separate homotypic aggregates. The final pattern of cell arrangement of homotypic aggregates depends on the relative seeding proportion of each cell type.

Stimulation of three distinct guanylate cyclases induces mucosal surface alkalinisation in rat small intestine in vitro.

The absorptive surface of the small intestine is isolated from bulk pH changes in the luminal contents by a zone of maintained low pH, the acid microclimate. The present study set out to compare the effects of stimulation of each of the three guanylate cyclases (GCs) expressed in the intestinal mucosa on the pH microclimate of rat jejunum in vitro. The tissue was exposed to specific ligands for each of the GCs and mucosal surface pH determinations were made by a miniaturised glass pH electrode.
