“…The results of adjusted analysis indicated that there were no significant patterns in relations between physical activity and cognitive decline in any of the three states. These findings differed from previous research that showed physical activity to be a neuroprotective factor [1][2][3][4][7][8][9].…”

“…In addition, this study examined females ages 55 to 64, whereas most previous research focused on the elderly [1,[6][7][8]12]. The variables in this study were concurrent levels of cognitive decline and physical activity levels at one point in time; therefore, benefits of physical activity for cognitive decline may not be immediate.…”

“…Many studies have shown that those who are physically active experience lower rates of cognitive decline [2,7,8]. IGF-1, a factor associated with neurogenesis, presents with diminished levels in elderly with poor cognitive performance.…”

Purpose: Physical activity could help prevent or slow deficits in cognition as an individual age; however, little is known about this relationship in females ages 55 to 64. The purpose of this study was to assess the relationship between physical activity levels and cognitive decline in females ages 55 to 64. Methods:This cross sectional analysis used 2015 data from the Behavioral Risk Factor Surveillance System (BRFSS) for females ages 55 to 64 in Connecticut, Montana, and Oregon. Logistic regression was used to assess the relationship between physical activity levels and cognitive decline while controlling for health and demographic factors.Results: Across states, few participants reported cognitive decline (10-14%), and only one-fifth reported being inactive (18-29%), while twice as many reported being highly active (34-48%). Adjusted results indicated that cognitive decline was not found to be significantly related to physical activity levels in any state, but cognitive decline was significantly related to number of health conditions, mental health, and substance use (all with moderate to large effect sizes) in two or three of three states. Conclusion:Across states, cognitive decline was not related to physical activity levels in females ages 55 to 64. The measurement for cognitive decline provided a limited scope of the condition and this study was unable to control for menopause and hormone replacement therapy, which may affect the outcome.Primary providers should not screen for physical activity levels related to cognitive decline in this population, but should screen for cognitive decline, multiple health conditions, current mental health issues, and substance use, if symptoms present for any of these in this target population.Providers should educate patients about the overall benefits of physical activity, but should focus on concurrently managing health conditions and discontinuing tobacco use as related to cognitive decline in females ages 55 to 64.

“…The primary objectives of studies have been and continue to be the evaluation and measurement of the cognitive benefits that PA can potentially confer with special attention to cognitively impaired individuals, including those with dementia [5, 6], Alzheimer’s disease [7], Parkinson’s disease [8, 9], schizophrenia [10], or mild cognitive impairment [11, 12]. Cognition has been measured along the domains of executive function, attention, memory, and working memory, each associated with distinct psychological measurement instruments.…”

BackgroundUnderstanding how physical activity (PA) influences cognitive function in populations with cognitive impairments, such as dementia, is an increasingly studied topic yielding numerous published systematic reviews. In contrast, however, there appears to be less interest in examining associations between PA and cognition in cognitively healthy individuals. Therefore, the objective of this review was to evaluate and synthesize randomized controlled trial (RCT) studies that investigated the effects of both chronic and acute PA on working memory performance (WMP) in physically and cognitively healthy individuals.MethodsFollowing the preferred reporting items for systematic review and meta-analysis (PRISMA) guidelines, a systematic review of studies published between August 2009 and December 2016 was performed on RCTs investigating the effects of chronic and acute PA on WMP with healthy participants as the sample populations. Searches were conducted in Annual Reviews, ProQuest, PsycARTICLES, PsycINFO, PubMed, and Web of Science. Main inclusion criteria stipulated (1) healthy sample populations, (2) PA interventions, (3) WMP as an outcome, and (4) RCT designs. Descriptive statistics included cohort and intervention characteristics and a risk of bias assessment. Analytical statistics included meta-analyses and moderation analyses.ResultsFrom 7345 non-duplicates, 15 studies (eight chronic PA and seven acute PA studies) met the inclusion criteria and were evaluated. Overall, there was noticeable variance between both cohort and intervention characteristics. Sample populations ranged from primary school children to retirement community members with PA ranging from cycling to yoga. The majority of studies were characterized by “low” or “unclear” risk of selection, performance, detection, attrition, reporting, or other biases. Meta-analysis of chronic PA revealed a significant, small effect size while analysis of acute PA revealed a non-significant, trivial result. Age and intensity were significant moderators while allocation concealment, blinding, and intervention length were not.ConclusionsChronic PA can significantly improve WMP while acute PA cannot. The limiting factors for acute PA studies point to the diversity of working memory instruments utilized, unequal sample sizes between studies, and the sample age groups. Large-scale, high-quality RCTs are needed in order to provide generalizable and more powerful analysis between PA and WMP in a systematic approach.Electronic supplementary materialThe online version of this article (doi:10.1186/s13643-017-0514-7) contains supplementary material, which is available to authorized users.

A inatividade física tem sido descrita como um dos principais problemas de saúde pública do século XXI. Neste contexto, a atividade física desempenha um papel importante na redução da prevalência de sedentarismo, melhorando a qualidade de vida e a saúde mental dos indivíduos. Objetivo: Este estudo teve como objetivo analisar a influência de seis meses de atividade física (AF) na qualidade de vida (QV) e estados de humor (EH) de adultos jovens. Métodos: Uma amostra de 32 indivíduos completou uma bateria de questionários para avaliar o seu nível de atividade física, qualidade de vida e estados de humor. Eles foram separados em dois grupos: sedentários (n = 15) e fisicamente ativos (n = 17). O International Physical Activity Questionnaire (IPAQ) foi utilizado para avaliar os níveis de AF, o WHO Quality of Life-BREF (WHOQOL_Bref) para QV e a Escala Brasileira de Humor (BRAMS) para os EH. Foi realizada análise fatorial de variância com medidas repetidas e teste post-hoc de Tukey (p ≤ 0,05) para QV e análise inferencial para os EH. Resultados: Escores de QV foram significantemente maiores para o grupo fisicamente ativo nos domí- nios ambiental e social. Da mesma forma, EH apresentaram maiores escores na dimensão Vigor para o grupo fisicamente ativo depois de seis meses, sem contudo, atingir os níveis de significância estatística. Conclusões: Estes resultados sugerem que AF pode influenciar positivamente aspectos na qualidade de vida do indivíduo. Contudo, os dados não evidenciam uma influência significativa da AF nos estados de humor
