Ageing-related declines in physiological attributes, such as muscle strength, can bring with them an increased risk of falls and subsequently greater risk of losing independence. These declines have substantial impact on an individual's functional ability. However, the precise relationship between falls risk and physical functionality has not been(More)
OBJECTIVES Moderate intensity aerobic exercise is known to facilitate cognitive performance but new technologies enable increasing opportunities to investigate this phenomenon under different circumstances. This study aimed to describe the effect of exercise on executive function assessed though a novel tablet-based test. DESIGN Twenty healthy, active(More)
PURPOSE Nitrate supplementation improves endurance exercise and single bouts of high-intensity activity, but its effect on repeated sprints is unclear. This study is the first to investigate the effects of acute dietary nitrate supplementation during a high-intensity intermittent-sprint test to exhaustion. METHODS Team-sport athletes (9 male, age 22.3 ±(More)
BACKGROUND Falls are of great concern to older adults and costly to the health system. In addition the relationship between falls risk and falls risk predictor characteristics is complex. OBJECTIVE This study aimed to explore the relationship between two objective fall-risk measures tools, the Physiological Profile Assessment and the Berg Balance Scale(More)
We sought to explore the relationship between two subjective falls-risk assessment tools (Falls Efficacy Scale-International [FES-I] and Activities-Specific Balance Confidence [ABC] Scale) and functional, health-related, and body composition characteristics. A total of 245 community-dwelling people aged 60 to 88 years underwent assessments for subjective(More)
This study sought to describe middle cerebral artery blood flow velocity (MCAv) during a 4 km cycling time trial, and relate it to different pacing strategies adopted by participants. After familiarisation and a standardised exercise protocol, 15 male trained cyclists rode a 4 km time trial on a cycling ergometer. MCAv was assessed via transcranial Doppler(More)
BACKGROUND Physical exercise is seen as a promising intervention to prevent or delay cognitive decline in individuals aged 50 years and older, yet the evidence from reviews is not conclusive. OBJECTIVES To determine if physical exercise is effective in improving cognitive function in this population. DESIGN Systematic review with multilevel(More)
