Purpose
The United Kingdom (UK) government imposed its first national lockdown in response to COVID-19 on the 23rd of March 2020. Physical activity and sedentary behaviour levels are likely to have changed during this period.
Methods
An online survey was completed by n = 266 adults living within the UK. Differences in day-to-day and recreational p...
Introduction: The introduction of the COVID-19 lockdown and social distancing policy has the potential to restrict access to physical activity, change exercise behavior, and to increase sedentary behavior. This study was conducted with the support of British Blind Sport and evaluates the effect of the lockdown policy on adults with visual impairmen...
1) Background: Near-infrared spectroscopy (NIRS) is an innovative and non-invasive technology used to investigate muscular oxygenation. The aim of this study is to assess the within-and between-session reliability of the NIRS Portamon (Artinis, Elst, Netherlands) device following three sets of induced muscle ischemia.

Objective
A suite of adaptations facilitating endurance running (ER) evolved within the hominin lineage. This may have improved our ability to reach scavenging sites before competitors, or to hunt prey over long distances. Running economy (RE) is a key determinant of endurance running performance, and depends largely on the magnitude of force requi...
This study investigated overarm throwing technique at different developmental ages in children from the perspective of three distinct, though potentially complementary, approaches to motor skill acquisition. Children at 6, 10, and 14 years of age (N = 18), completed dominant overarm throws during which whole-body kinematic data were collected. Firs...

Introduction
Variations in plateau incidence at VO2max are shown to be related to the size of the finite anaerobic capacity (AnC). However, the AnC only refers to substrate availability and does not reflect changes in intracellular metabolites associated with fatigue processes which are evident at VO2max. The anaerobic work capacity (AWC) (W’) deri...
BACKGROUND: Union Ciycliste Internationale (UCI) rule 1.3.014 states, “The plane passing through the highest points at the front and rear of the saddle shall be horizontal”. The presupposition of this rule is, “an excessively sloping saddle could improve sporting performance to an unacceptable degree by the addition of a lumbar support”. Following...
