Effect of Foreperiod Duration and Handedness on Simple and Choice Auditory Reaction Time Among the Older People

2017

Objectives Cognitive functions such as reaction time undergo change with aging. Given the importance of preparation in response to reaction time in various life situations, this study aimed to examine the effect of various foreperiods (0.5, 1.5, 2.5, and 3.5 s), and handedness at the time of simple and choice auditory reaction time. Methods & Materials The current research followed a quasi-experimental methodology and was carried out using a self-made software. The study population comprised all old people living in Ahvaz City. Of them, 30 people were selected through purposive sampling method and allocated into two groups of right- and left-handed people. Each individual was randomly teste…

Physical Activity Scaled to Preferred Walking Speed as a Predictor of Walking Difficulty in Older Adults: A 2-Year Follow-up

2021

Abstract Background The usual accelerometry-based measures of physical activity (PA) are dependent on physical performance. We investigated the associations between PA relative to walking performance and the prevalence and incidence of early and advanced walking difficulties compared to generally used measures of PA. Methods Perceived walking difficulty was evaluated in 994 community-dwelling participants at baseline (age 75, 80, or 85 years) and 2 years later over 2 km (early difficulty) and 500 m (advanced difficulty). We used a thigh-mounted accelerometer to assess moderate-to-vigorous PA, daily mean acceleration, and relative PA as movement beyond the intensity of preferred walking spee…

Toxicological and bioactivity evaluation of blackcurrant press cake, sea buckthorn leaves and bark from Scots pine and Norway spruce extracts under a…

2021

Aqueous extracts from blackcurrant press cake (BC), Norway spruce bark (NS), Scots pine bark (SP), and sea buckthorn leaves (SB) were obtained using maceration and pressurized hot water and tested for their bioactivities. Maceration provided the extraction of higher dry matter contents, including total phenolics (TPC), anthocyanins, and condensed tannins, which also impacted higher antioxidant activity. NS and SB extracts presented the highest mean values of TPC and antioxidant activity. Individually, NS extract presented high contents of proanthocyanidins, resveratrol, and some phenolic acids. In contrast, SB contained a high concentration of ellagitannins, ellagic acid, and quercetin, exp…

The mediating role of behavioural automaticity and intention on past to future bootcamp attendance

2023

Objective The aim of the current study was to test whether behavioural automaticity and intention mediated the effects of past behaviour on a particular type of vigorous physical exercise: bootcamp attendance. Methods A community sample (N = 69) who had previously attended a bootcamp class was recruited from Queensland, Australia. Participants were asked to complete measures of their previous bootcamp attendance, behavioural automaticity, and intention to attend bootcamps (Time 1). One month later (Time 2), participants were asked to report their bootcamp attendance and behavioural automaticity in the previous month. Data were fitted to a Partial Least Squares-SEM model. Results Past behavi…

Continuity and changes in commuting mode and influence on physical activity, BMI and waist circumference among Finnish adults

2022

Regular physical activity (PA) has been found to be important for cardiovascular health and longevity. However, notable proportion of adult population does not meet the national PA recommendations. Active transport is one domain of physical activity, that could be a time-efficient way to increase PA and reach the national recommendations. Additionally, it could have a positive effect to body composition. nonPeerReviewed

A scoping review on interventions to promote physical activity among adults with disabilities

2016

People with disabilities are at increased risk for obesity as well as other secondary conditions that lead to further decline in health and functional status. Despite there being strong evidence that physical activity (PA) can help to reduce the incidence and severity of preventable conditions, approximately half of all adults with disabilities get no regular physical activity. In addition, there is limited knowledge on the PA promotion interventions effectiveness among individuals with disabilities. Recently the Behaviour Change Techniques Taxonomy version 1 (BCT Taxonomy v1) became available as a method for reporting, replicating, and synthesizing research evidence, yet it is lacking in s…

The structural effect between the output module and chromophore-binding domain is a two-way street via the hairpin extension.

2022

AbstractSignal transduction typically starts with either ligand binding or cofactor activation, eventually affecting biological activities in the cell. In red light-sensing phytochromes, isomerization of the bilin chromophore results in regulation of the activity of diverse output modules. During this process, several structural elements and chemical events influence signal propagation. In our study, we have studied the full-length bacteriophytochrome from Deinococcus radiodurans as well as a previously generated optogenetic tool where the native histidine kinase output module has been replaced with an adenylate cyclase. We show that the composition of the output module influences the stabi…
