Effects of detraining on neuromuscular function and structural adaptations following once- or twice-weekly eccentric resistance training in older adults.

Background: Eccentric resistance training elicits greater preservation of training-induced muscular adaptations compared with other training modalities, however the detraining profiles of different training dosages remain unknown.

Aims: To examine the detraining effects following once- or twice-weekly eccentric-specific resistance training in older adults.

Methods: Twenty-one older adults (age = 70.

Effects of once- versus twice-weekly eccentric resistance training on muscular function and structure in older adults: a randomised controlled trial.

Adherence rates to current twice-weekly strength training guidelines are poor among older adults. Eccentric-only training elicits substantial improvements in muscle function/size so the aim of this study was to compare the effects of once- versus twice-weekly eccentric training programmes on muscle function/size in older adults. Thirty-six participants (69.

Delapré Walk project: Are signposted walking routes an effective intervention to increase engagement in urban parks? -Natural experimental study.

Spatial education interventions in the built environment may increase engagement with urban greenspace. This research was a natural experimental study with mixed-method evaluation and repeated cross-sectional design. Twenty-four directional wayfinding signs were installed within an urban park to create a 3 km signposted walking route through the park's amenities in a clockwise direction.

The acute and repeated bout effects of multi-joint eccentric exercise on physical function and balance in older adults.

Purpose: Eccentric muscle actions generate high levels of force at a low metabolic cost, making them a suitable training modality to combat age-related neuromuscular decline. The temporary muscle soreness associated with high intensity eccentric contractions may explain their limited use in clinical exercise prescription, however any discomfort is often alleviated after the initial bout (repeated bout effect). Therefore, the aims of the present study were to examine the acute and repeated bout effects of eccentric contractions on neuromuscular factors associated with the risk of falling in older adults.

Influence of COVID-19 Building Restrictions on Physical Activity Promotion Through Increased Stair Use and Limited Elevator Access: A Quasi-Experimental Study-Sport and Physical Activity Group Active Campus Project.

Background: The aim of this study was to determine the effectiveness of UK government COVID-19 safe offices policy to increase stair use in a higher education setting during the COVID-19 pandemic.

Methods: Automated counts at 3 ground floor staircases and the elevator entrances were used to estimate stair to elevator use ratio for ascent and descent from/to the ground floor of a university building at baseline (January to March 2020), first and second intervention months (October 2020, November 2020, respectively). Stair promoting signage and a 1-way system was implemented, in line with government policy.

Correction to: The difference in sleep, sedentary behaviour, and physical activity between older adults with 'healthy' and 'unhealthy' cardiometabolic profiles: a cross-sectional compositional data analysis approach.

The difference in sleep, sedentary behaviour, and physical activity between older adults with 'healthy' and 'unhealthy' cardiometabolic profiles: a cross-sectional compositional data analysis approach.

Background: Studies have seldom used Compositional Data Analysis (CoDA) to map the effects of sleep, sedentary behaviour, and physical activity on older adults' cardio-metabolic profiles. This study therefore aimed to illustrate how sleep, sedentary behaviour, and physical activity profiles differ between older adult groups (60-89 years), with 'low' compared to those with 'high' concentrations of endocrine cardio-metabolic disease risk markers, using CoDA.

Method: Ninety-three participants (55% female) wore a thigh-mounted triaxial accelerometer for seven consecutive free-living days.

Using isotemporal substitution to predict the effects of changing physical behaviour on older adults' cardio-metabolic profiles.

Background: It has been advocated that older adults should concomitantly spend less time in sedentary behaviour (SB), and engage in sufficient physical activity (PA), to reduce their risk of cardio-metabolic diseases. However, it is not clear what intensity of PA must be done to offset SB engagement.

Aim: Model how cardio-metabolic profiles could change if older adults replaced an hour per day (hr·day-1) of a physical behaviour intensity with 1 hr·day-1 of another physical behaviour of a different intensity.

Reliability and validity of the international physical activity questionnaire compared to calibrated accelerometer cut-off points in the quantification of sedentary behaviour and physical activity in older adults.

Background: The aim was to determine the reliability and validity of IPAQ measured sedentary behaviour (SB) and moderate-vigorous physical activity (MVPA) in older persons whilst examining any sex differences in reliability and validity results.

Method: 89 participants (73.7 ± 6.

Segregating the Distinct Effects of Sedentary Behavior and Physical Activity on Older Adults' Cardiovascular Profile: Part 2-Isotemporal Substitution Approach.

Background: The aim of the study was to provide an isotemporal substitution model to predict how changes in physical behavior may affect the cardiovascular parameters (CVPs) of older adults.

Methods: Participants wore a thigh-mounted accelerometer for 7 days. Phenotype of the carotid, brachial, and popliteal artery was conducted using ultrasound.
