Background The aim was to determine the reliability and validity of IPAQ measured sedentary behaviour (SB) moderate–vigorous physical activity (MVPA) in older persons whilst examining any sex differences results. Method 89 participants (73.7 ± 6.3 years, 54% female) completed IPAQ. Participants were fitted with a thigh mounted triaxial accelerometer (GeneActiv Original) for seven consecutive days subsequently second Results showed weak qualities Total SB (h·week-1) 10 minute MVPA...

Abstract Adherence rates to current twice-weekly strength training guidelines are poor among older adults. Eccentric-only elicits substantial improvements in muscle function/size so the aim of this study was compare effects once- versus eccentric programmes on Thirty-six participants (69.4 ± 6.0 yr) were randomised into non-active control, once-, or groups. Lower-limb power, strength, and size assessed at baseline, mid-, post-eccentric training. Training performed for 12 min per session 50%...

Attendance at university often presents significant personal, environmental, and social changes to an individual. Such are likely exacerbated in young students given the transition from living home, increased independence that attendance requires. These factors may influence dietary habits of students, which is important consider for long-term health maturation, as well academic performance. In this study, a survey was cross-sectionally distributed obtain both qualitative quantitative data...

Sedentary behaviour (SB) has emerged as an independent public-health risk and may contribute to the lower bone mineral density (BMD) in old (>60 years of age) than young adults. The purpose this study was quantify SB habitual physical (PB) community-dwelling older adults how correlates with BMD. In 112 relatively healthy independent-living individuals aged 72.56.4 years, BMD, PB were determined using dual energy x-ray absorptiometry 7-day three-dimensional accelerometry, respectively. men,...

Using infrared counters is a promising unobtrusive method of assessing footfall in urban parks. However, are susceptible to reliability and validity issues, there limited guidance for their use. The aims this study were (1) determine how many weeks automated active count data would provide behaviourally stable estimates park each meteorological season, (2) the comparison direct manual observation counts.

The study explored public perceptions of the role that wayfinding signage can play to enhance engagement with recreational walking routes in greenspaces. A mixed-methods online survey was distributed within Northampton, England and there were 266 respondents. had Likert scale open text answer options allow for respondents share richer opinions. Key themes suggested increased participants' confidence explore, safety, motivation walk further, reduced anxiety. 33% strongly agreed should be...

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

This study explores urban park users' engagement with a wayfinding intervention from natural experimental study- The Delapré Walk Project. A qualitative approach was taken, 16 intercept go-along interviews conducted 28 local users while they engaged the greenspace. Barriers to greenspace access included lack of seating and unfamiliarity distances footpath terrains. inclusion walking route distance on signage valued by visitors, enabling them make capability decisions about be walked. offered...

Abstract Background Eccentric resistance training elicits greater preservation of training-induced muscular adaptations compared with other modalities, however the detraining profiles different dosages remain unknown. Aims To examine effects following once- or twice-weekly eccentric-specific in older adults. Methods Twenty-one adults (age = 70.5 ± 6.0 year) completed a 12-week period eccentric programmes neuromuscular function and muscle structure assessed six (mid-detraining) 12...

Abstract 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 illustrate how profiles differ between adult groups (60–89 years), with ‘low’ compared those ‘high’ concentrations endocrine disease risk markers, using CoDA. Method Ninety-three participants (55% female) wore a thigh-mounted triaxial accelerometer for seven consecutive...

Physical behavior [PB, physical activity (PA), and sedentary (SB)] can adjust cardiovascular mortality risk in older adults. The aim of this study was to predict parameters (CVPs) using 21 PB.Participants [n = 93, 73.8 (6.23) y] wore a thigh-mounted accelerometer for 7 days. Phenotype the carotid, brachial, popliteal arteries conducted ultrasound.Sedentary associated with one 19 CVPs. Standing light-intensity PA 3 1 CVP, respectively. Our prediction model suggested that an hourly increase...

Background It has been advocated that older adults should concomitantly spend less time in sedentary behaviour (SB), and engage sufficient physical activity (PA), to reduce their risk of cardio-metabolic diseases. However, it is not clear what intensity PA must be done offset SB engagement. Aim Model how profiles could change if replaced an hour per day (hr·day-1) a with 1 hr·day-1 another different intensity. Methods Older (n = 93, 60–89 years old, 55% female) wore thigh-mounted triaxial...

Greenspaces are recognised as important assets for supporting and promoting human flourishing in an increasingly urbanised world. Whilst much epidemiological research has shown the various health benefits of urban greenspaces, far less work focused on personal everyday interactions with, within, them. By examining social significance this article shows how they resources people use within their to enhance a broadly defined understanding wellbeing. The insight draws data from 'intercept...
