Background: This study examines the impact of participating in a seven-week football programme on the personal well-being of male asylum seekers residing in contingency accommodation in the UK. Methods: This repeated measures study included a cohort of participants who engaged in weekly football sessions and completed a well-being questionnaire (ON...

Video assistant referee (VAR) has been introduced to elite football (soccer) to avoid clear and obvious mistakes, especially for goal scoring situations. Some literature has reported on VAR’s impact on the game across particular league competitions. The current study meta-analysed data across two seasons (pre-VAR and post-VAR) from 20 competitions...

High amplitudes of shock during running have been thought to be associated with an increased injury risk. This study aimed to quantify the association between dual-energy X-ray absorptiometry (DEXA) quantified body composition, and shock attenuation across the time and frequency domains. Twenty-four active adults participated. A DEXA scan was perfo...

Background This study assessed the specific influence of physical activity (PA) and waist circumference (WC) on the 4-year growth trajectory of blood pressure in UK high-school students. Methods Four-year longitudinal monitoring of 1501 adolescents was conducted as part of the EoEHHS. Measurements were taken in Grades (G)7, 9, and 11. Results Sys...

Context: Cold-water immersion (CWI) is reported to reduce tissue metabolism post immersion, yet there is a lack of physiologic data regarding muscle metabolic response to its application. Near-infrared Spectroscopy (NIRS) is a non-invasive optical technique that can inform upon muscle haemodynamics and tissue metabolism. Objective: The purpose o...

The purposes of the present investigation were: 1) to explore the utility of Near Infrared Spectroscopy (NIRS) as a measurement tool within triathlon; 2) create a profile of the physiological responses to triathlon. A laboratory based study explored the utility of multi-site NIRS as a measurement tool within triathlon using recreational male triath...

This brief overview and commentary explores the effect of exercise training on muscular strength, and the influence of genetics on the level of response and adaptation between individuals. We aim to outline and explore some limitations within the current research and discuss how future research could address these. Muscular strength is a vital comp...

Introduction: New Zealand Blackcurrant Extract (NZBC) is a popular ergogenic aid used to improve endurance performance. The aim of this research was to determine the effects of a single bolus of NZBC on 10-km time trial (TT) cycling performance in normobaric hypoxia. Methods: A double-blind, crossover design study was conducted with trained cyclist...

Objectives Explore the feasibility of lower-limb garment-integrated BFR-training. Design Observational study. Setting Human performance laboratory. Participants Healthy males with no experience of BFR-training. Main outcome measures Feasibility was determined by a priori thresholds for recruitment, adherence, and data collection. Safety was det...

The aim of the present study was to examine whether full leg-length compression tights modify physiological and kinematic measures during treadmill running at a competitive race pace in moderately trained runners. Thirteen males and five females completed two 15-minute running tests at a speed corresponding to a recent race time wearing compression...

The effect of compression tights on running economy is unclear. The purpose of this investigation was to assess the influence of compression tights on economy. Following an incremental test to exhaustion to determine aerobic capacity (V̇O 2max) and peak running speed (vV̇O 2max), twenty-six moderately endurance-trained males (28 ± 7 years; 76.1 ± 8...

Objective: The aim of this study was to assess the extent of misreporting in obese and nonobese adults on an absolute, ratio-scaled, and allometrically-scaled basis. Method: Self-reported daily energy intake (EI) was compared with total energy expenditure (TEE) in 221 adults (106 male, 115 female; age 53 ± 17 years, stature 1.68 ± 0.09 m, mass 7...

The interface pressure applied by compression clothing is an important measure in evaluating the efficacy of the bio-physical impact of compression. The aim was to compare two portable pneumatic pressure measuring devices (PicoPress and Kikuhime), against a non-portable, Hohenstein System (HOSY) reference standard, used by medical regulatory agenci...

The purpose of the study was to compare muscle oxygenation as measured by two portable, wireless near-infrared spectroscopy (NIRS) devices under resting and dynamic conditions. A recently developed low-cost NIRS device (MOXY) was compared against an established PortaMon system that makes use of the spatially resolved spectroscopy algorithm. The inf...

The aim of this case study is to describe the nutrition practices of a female recreational runner (VO2max 48.9 ml·kg⁻¹·min⁻¹) who completed 26 marathons (42.195 km) in 26 consecutive days. Information relating to the nutritional intake of female runners during multi-day endurance events is extremely limited, yet the number of people participating y...

Objectives: Compression garments are used by athletes in attempts to enhance performance and recovery, although evidence to support their use is equivocal. Reducing the exertion experienced during exercise may encourage sedentary individuals to increase physical activity. The aim of this study was to assess the effect of compression garments on wa...

D1.P43. The validity of the VASA swim ergometer in the assessment of swimmers in the laboratory KELLY MURRAY, CHRIS MCMANUS & DAVID PARRY* University of Essex *Corresponding author: dapcoach@essex.ac.uk The physiological assessment of swimmers presents numerous challenges. Simulated swimming (SS) has been shown to elicit similar physiological respo...
