Effects of a multicomponent training and detraining on frailty status, physical activity level, sedentary behavior patterns and physical performance of pre-frail older adults: a randomized controlled trial.

Purpose: To evaluate the effects of a multicomponent training protocol and detraining on frailty status, physical activity level, sedentary behavior patterns, and physical performance in pre-frail older adults.

Methods: A randomized controlled blinded trial was conducted with pre-frail older adults (74.8 ± 6.

Monitoring SARS-CoV-2 seroprevalence over time among pregnant women admitted to delivery units: Suitability for surveillance.

Objectives: To determine SARS-CoV-2 seroprevalence over time and risk factors among pregnant women at delivery in São Paulo, Brazil; and to evaluate the suitability of pregnant women as a sentinel population for SARS-CoV-2 serosurveillance.

Methods: Unselected consecutive pregnant women presenting at the labor ward of a single large hospital between July 20th 2020 to February 21st 2021 were enrolled and tested for SARS-CoV-2 serology using two assays: the rapid chromatic Wondfo One Step (for total IgA and IgG detection) and Roche Elecsys assay (detecting anti-nucleoprotein [N] IgG). SARS-CoV-2 seroprevalence was computed as smooth spline function over time with 95% confidence intervals (CI).

Self-management strategies and multicomponent training to mitigate the effects of the interruption of physical exercise programmes in the pandemic context on functionality, sedentary behaviour, physical capacity, mental health, body composition and quality of life in older adults: a blinded randomized controlled study protocol.

Background: Considering the confinement recommended by the World Health Organization due to the pandemic caused by COVID-19, many community physical exercise programmes for older adults have had their activities cancelled. In this context, proposing strategies to recover the possible adverse effects of the confinement period is pertinent. The use of self-management strategies associated with regular physical activity reduces sedentary behaviour and improves physical capacity in older adults.

Cardiac Autonomic Modulation Response Before, During, and After Submaximal Exercise in Older Adults With Intellectual Disability.

The analysis of the heart rate variability (HRV) consists of changes in the time intervals between consecutive R waves. It provides information on the autonomic nervous system regulation and it is a predictor of adverse cardiovascular events. Several studies analyzed this parameter in youth and adults with Intellectual Disability (ID).

Effects of aquatic physical exercise on neuropsychological factors in older people: A systematic review.

Background: . There is a lack of standardized protocols and clinical trials for older adults involving neuropsychological factors in the literature. Furthermore, no systematic review has been published investigating this theme.

Effects of physical exercise on the cognition of older adults with frailty syndrome: A systematic review and meta-analysis of randomized trials.

Objectives: To analyze the effects of physical exercise on the cognition of community-dwelling older adults with frailty syndrome, through randomized clinical trials.

Data Sources: Articles published until March 2020 were searched in the databases Science Direct, Scopus, Web of Science, PubMed, Lilacs, Cochrane, IEEE, EMBASE, and SciELO. Search terms included frailty, aged, exercise, rehabilitation, and cognition.

Complexity of knee extensor torque in patients with frailty syndrome: a cross-sectional study.

Background: Frailty syndrome is characterized by a marked reduction in physiological reserves and a clinical state of vulnerability to stress. Torque complexity analysis could reveal changes in the musculoskeletal systems that are the result of having the syndrome.

Objective: The aim of this study was to evaluate the complexity of submaximal isometric knee extensor torque in frail, pre-frail, and non-frail older adults.

Dual-Task Performance: Influence of Frailty, Level of Physical Activity, and Cognition.

Background And Purpose: Cognition and level of physical activity have been associated with frailty syndrome. The development of tools that assess deficits related to physical and cognitive frailties simultaneously are of common interest. However, little is known about how much these aspects influence the performance of dual-task tests.

Performance of Different Timed Up and Go Subtasks in Frailty Syndrome.

Background And Purpose: Gait speed, mobility, and postural transitions should be taken into account in older adults with frailty syndrome and can be assessed by the Timed Up and Go (TUG) Test. However, it is unclear which TUG subtasks have greater influence in identifying frail people and whether prefrail individuals present with any reduced subtask performance. The objective of this study was to investigate the differences in performance of TUG subtasks between frail, prefrail, and nonfrail older adults.

Effects of the Addition of a Dual Task to a Supervised Physical Exercise Program on Older Adults' Cognitive Performance.

The purpose of this study was to investigate the effects of the addition of a dual task to multicomponent training on cognition of active older adults. Eighty physically active older adults were divided into an intervention group (IG) and a control group (CG). Both groups performed multicomponent training over 12 weeks.
