Performance measures provide important information, but the meaning of change in these is not well known. The purpose this research to 1) examine effect treatment assignment on relationship between self-report and performance; 2) estimate magnitude meaningful 400-meter walk time (400MWT), 4-meter gait speed (4MGS), Short Physical Battery (SPPB) 3) evaluate direction estimates magnitude.
<h3>Importance</h3> Epidemiological evidence suggests that physical activity benefits cognition, but results from randomized trials are limited and mixed. <h3>Objective</h3> To determine whether a 24-month program in better cognitive function, lower risk of mild impairment (MCI) or dementia, both, compared with health education program. <h3>Design, Setting, Participants</h3> A clinical trial, the Lifestyle Interventions Independence for Elders (LIFE) study, enrolled 1635 community-living...
W ITH persons aged ≥70 years representing the fastest growing segment of U.S. population (1), preventing disability and maintaining independence throughout later life is an important public health goal (2,3).Mobility activities daily living are necessary for basic independent functioning (4,5).The inability to perform these tasks a critical threshold, conferring increased risk illness, institutionalization, reductions in quality life, death (6,7).
A randomized controlled trial examined the growth and form of multidimensional self-esteem over a 12-month period (6-month exercise intervention 6-month follow-up) in 174 older adults engaged either walking or stretching/toning program. The extent to which changes physical fitness parameters self-efficacy were related perceptions attractive body, strength, conditioning, self-worth was also determined. Latent curve analyses showed curvilinear pattern esteem with significant increases at all...
OBJECTIVE Although the Diabetes Prevention Program (DPP) and Finnish Study (FDPS) demonstrated that weight loss from lifestyle change reduces type 2 diabetes incidence in patients with prediabetes, translation into community settings has been difficult. The objective of this study is to report first-year results a community-based DPP (LWL) intervention on fasting glucose, insulin resistance, adiposity. RESEARCH DESIGN AND METHODS We randomly assigned 301 overweight obese volunteers (BMI...
Abstract Objective To examine changes in mobility‐related self efficacy following exercise and dietary weight loss interventions overweight obese older adults with knee osteoarthritis (OA), to determine if pain mediate the effects of on mobility task performance. Methods The Arthritis, Diet, Activity Promotion Trial was an 18‐month, single‐blind, randomized, controlled trial comparing alone, a combination plus loss, healthy lifestyle control intervention treatment 316 or symptomatic OA....
The efficacy of non-pharmacological intervention approaches such as physical activity, strength, and cognitive training for improving brain health has not been established. Before definitive trials are mounted, important design questions on participation/adherence, interventions effects must be answered to more fully inform a full-scale trial.SHARP-P was single-blinded randomized controlled pilot trial 4-month activity (PA) and/or (CT) in 2 × factorial with education control condition 73...
In light of the need to expand reach and access clinically proven digital Diabetes Prevention Programs (d-DPPs) for rigorous evidence effectiveness, purpose this study was determine effectiveness a Program improving weight, HbA1c, cardiovascular risk factors among people with prediabetes compared enhanced standard care plus waitlist control.This single-blind RCT participants at developing type 2 diabetes included 12 months follow-up.A total 599 volunteer patients were recruited primarily...
Observational evidence suggests that higher physical activity is associated with slower kidney function decline; however, to our knowledge, no large trial has evaluated whether and exercise can ameliorate decline in older adults.
Abstract INTRODUCTION The U . S study to pr o tect brain health through lifestyle inte rvention r educe risk (U.S. POINTER) is conducted confirm and expand the results of Finnish Geriatric Intervention Study Prevent Cognitive Impairment Disability (FINGER) in Americans. METHODS U.S. POINTER was planned as a 2‐year randomized controlled trial two interventions 2000 older adults at for dementia due well‐established factors. primary outcome global cognition composite that permits harmonization...
Abstract Increasing evidence suggests that regular physical activity can have considerable psychological, as well physical, benefits in the elderly. Although factors such exercise dosage may be implicated exercise-induced affect responses, it has also been suggested social and psychological might influence this relationship. This study examined roles played by environment (group versus alone) self-efficacy affective change 80 older adults (M age = 66 yrs) over course of three acute bouts....
Although progressive resistance strength training (ST) has been found to improve various measures of physical functioning in older adults, the benefit quality life is unclear. Additionally, recent evidence suggests that high velocity power (PT) may be more beneficial for than ST, but it not known whether this type impacts life. The purpose study was compare changes multiple resulting from ST vs. PT adults. A no exercise group also included as control comparison condition. Forty-five adults...
Purpose: Lifestyle Interventions and Independence for Elders Pilot (LIFE-P) was a trial to examine the effects of physical activity intervention (PA) compared with health education control (SA) on measures disability risk in sedentary older adults (N = 424). We examined adherence LIFE-P PA first 12 months trial. Methods: The consisted walking, strength, flexibility, balance training supplemented behavioral skills modules, it used phased, center-based schedule adoption (3× wk−1, weeks 1-8),...
OBJECTIVES: To determine whether participation in usual moderate‐intensity or more‐vigorous physical activity (MVPA) is associated with function performance and to identify sociodemographic, psychosocial, disease‐related covariates that may also compromise performance. DESIGN: Cross‐sectional analysis of baseline variables a randomized controlled intervention trial. SETTING: Four academic research centers. PARTICIPANTS: hundred twenty‐four older adults aged 70 89 at risk for mobility...
Abstract: The Lifestyle Interventions and Independence for Elders (LIFE) Study is a Phase III randomized controlled clinical trial (Clinicaltrials.gov identifier: NCT01072500) that will provide definitive evidence regarding the effect of physical activity (PA) on major mobility disability in older adults (70–89 years old) who have compromised function. This paper describes methods employed delivery LIFE PA intervention, providing insight into how we promoted adherence monitored fidelity...
A randomized controlled trial examined the effect of two physical activity modes on changes in self-efficacy over course a 12-month period older, formerly sedentary adults (N = 174, M age 65.5 years). Participants were into either an aerobic group or stretching and toning group. Structural equation modeling was employed to conduct multiple sample latent growth curve analyses individual exercise time. Results revealed curvilinear pattern for both types efficacy with increases occurring first...
We examined the hypothesis that physical activity will have favorable effects on measures of self-efficacy for a 400-m walk and satisfaction with functioning in older adults 70+ years age who deficits mobility. randomized total 412 aged 70–89 at elevated risk mobility disability to either or successful aging educational control intervention 12 months. Participants had more changes both outcomes as result treatment than those intervention. Gender, age, scores short performance battery did not...
