Testing Interventions for Mobility through Exercise (TIME): Study protocol for a randomized trial comparing a novel, brief home-based exercise program and a standard home-based group exercise for older adults with mobility disability.

One in four older adults report difficulty walking, greatly increasing the risk of future disability and death. Though exercise improves mobility, too few older adults do it. While studies show that brief exercise sessions provide most of the benefit of longer sessions and that older adults note that "time" is a critical barrier to being active, what remains unknown is whether briefer RT sessions can improve mobility as well as, or better than, longer traditional sessions, possibly due to greater adherence.

Friend Social Network Size Moderates the Association Between Age and Physical Activity Across Adulthood.

Both physical activity and social network size decline as people age. However, limited research has examined if social network size and contact frequency differentially influence physical activity across the adult lifespan. This study aimed to assess if these social network characteristics moderated the relationship between age and physical activity level across adulthood.

AYA-UNITE: Lessons Learned on Intervention Development Promoting Social and Physical Health of Adolescent/Young Adult Cancer Survivors.

Adolescent/young adult cancer survivors (AYACS) struggle with poor psychosocial health related to social disruptions due to cancer diagnosis, impacting long-term goal achievement and overall health. In particular, social health promotion is overlooked in AYACS' care. AYA-UNITE, a sociobehavioral exercise intervention pilot for AYACS 15-21 years of age at cancer diagnosis, was designed to foster AYACS' social and physical health.

Effects of Desk Pedaling Work Rate on Concurrent Work Performance among Physically Inactive Adults: A Randomized Experiment.

Purpose: Under-desk pedaling devices could help reduce health risks associated with the global decline in work-related energy expenditure. However, the optimal pedaling work rate to facilitate concurrent work performance among physically inactive adults is unclear. We examined the effects of two light-intensity pedaling work rates on physically inactive adults' work performance.

The Association between Gender and Physical Activity Was Partially Mediated by Social Network Size during COVID-19.

The COVID-19 pandemic has disrupted physical activity, particularly among women. Limited research has explored how social network support may explain gender-based variations in physical activity during COVID-19. The purpose of this study was to examine the mediating role of social networks in the association between gender and physical activity during a pandemic.

Adult outdoor group sport play during a pandemic: Feasibility, acceptability, and program adherence results from a study of modifications to mitigate COVID-19 risk.

The purpose of this study was to investigate the feasibility, acceptability, and short-term adherence to an adult outdoor group sport play program designed to maximize enjoyment that was modified to incorporate COVID-19 risk mitigation strategies. We enrolled 17 healthy, but sedentary, central Pennsylvania adults (  = 31.6 ± 7.

Comparative effectiveness of an adult social physical play versus traditional group exercise program for adherence and fitness: Protocol for a randomized-controlled trial.

Despite the myriad benefits associated with regular physical activity (PA), few American adults accrue sufficient weekly PA. Although "lack of time" is often cited as a correlate of physical inactivity, a growing body of evidence suggests that, perhaps more importantly, people allocate their leisure-time to activities they find more enjoyable than PA. These findings underscore the need to devise physical activities that will be chosen over other enjoyable, but less healthy, behavioral alternatives.

Effects of Bluetooth-Enabled Desk Ellipticals on Office Work Performance: Rationale, Design, and Protocol for a Randomized Trial With Overweight and Obese Adults.

Background: Workplaces that provide opportunities for physical activity without requiring extra time for activity could help counteract the obesity epidemic. Desk ellipticals can contribute to activity-supportive workplace environments; however, the feasibility of engaging employees in pedaling ellipticals during simultaneous office work has not been well evaluated.

Objective: We aim to present the rationale and methods from an ongoing randomized trial with overweight and obese employees that will evaluate (1) the effects of pedaling a compact desk elliptical on work performance and (2) the influence of different incentive types and schedules on desk pedaling quantity.

Adults Want to Play Too: Feasibility of an Adult Physical Activity Program Designed to Maximize Enjoyment.

Background: Few adults in the United States obtain sufficient physical activity (PA) despite knowledge of the associated health benefits. The current feasibility study examined the feasibility of a novel modified sports intervention designed to promote enjoyment and sustained PA in sedentary adults.

Methods: The US adults (N = 22, mean age 39.

Why just exercise if you can play? Interest in a modified sports program to enhance physical activity among primary care patients.

Fewer adults meet guidelines for aerobic physical activity, and many report a lack of enjoyment as a barrier. This survey was designed to determine the interest of primary care patients in participating in program designed to maximize enjoyment. Primary care patients (n = 540) in Central Pennsylvania reported their interest in participating in a "a regular fitness program where people your own age played games, such as softball, floor hockey and soccer, that were made to be easier to play and less competitive.

Physical Activity Mode and Mental Distress in Adulthood.

Introduction: Nearly one fifth of American adults suffer from mental health issues, yet many treatments have side effects and stigma attached. Physical activity can be an effective treatment for mental health disorders, but most promotion efforts fail. One understudied aspect of physical activity is the specific mode, including if it engages others, and how this may relate to mental health.

Engineering Online and In-Person Social Networks for Physical Activity: A Randomized Trial.

Background: Social networks can influence physical activity, but little is known about how best to engineer online and in-person social networks to increase activity.

Purpose: The purpose of this study was to conduct a randomized trial based on the Social Networks for Activity Promotion model to assess the incremental contributions of different procedures for building social networks on objectively measured outcomes.

Methods: Physically inactive adults (n = 308, age, 50.

Is strength training associated with mortality benefits? A 15year cohort study of US older adults.

Background: The relationship between strength training (ST) behavior and mortality remains understudied in large, national samples, although smaller studies have observed that greater amounts of muscle strength are associated with lower risks of death. We aimed to understand the association between meeting ST guidelines and future mortality in an older US adult population.

Methods: Data were analyzed from the 1997-2001 National Health Interview Survey (NHIS) linked to death certificate data in the National Death Index.

Interest in Using Workplace Energy Expenditure Devices Among Primary Care Patients.

Background: Workplace energy expenditure devices (WEEDs), such as bicycle desks and treadmill desks, can contribute to weight gain prevention and disease risk-reduction. Little is known about the extent to which adults with diverse health risk factors are interested in using WEEDs.

Methods: Primary care patients aged 18 to 65 years at 2 outpatient clinics in Central Pennsylvania completed a cross-sectional survey in April, 2014 to assess interest in using "a small pedaling device under the desk" and "walking on a treadmill with a desk attached" if these options were provided at no cost.

A Growing Opportunity: Community Gardens Affiliated with US Hospitals and Academic Health Centers.

Background: Community gardens can reduce public health disparities through promoting physical activity and healthy eating, growing food for underserved populations, and accelerating healing from injury or disease. Despite their potential to contribute to comprehensive patient care, no prior studies have investigated the prevalence of community gardens affiliated with US healthcare institutions, and the demographic characteristics of communities served by these gardens.

Methods: In 2013, national community garden databases, scientific abstracts, and public search engines (e.

Complete home smoking bans and antitobacco contingencies: a natural experiment.

Introduction: The California antitobacco culture may have influenced home smoking bans in Mexico. Based on the Behavioral Ecological Model, exposure to socially reinforcing contingencies or criticism may explain adoption of home smoking bans in Tijuana, Mexico, approximating rates relative to San Diego, California, and higher than those in Guadalajara, Mexico.

Methods: A representative cross-sectional population survey of Latinos (N = 1,901) was conducted in San Diego, Tijuana, and Guadalajara between June 2003 and September 2004.

Engineering online and in-person social networks to sustain physical activity: application of a conceptual model.

Background: High rates of physical inactivity compromise the health status of populations globally. Social networks have been shown to influence physical activity (PA), but little is known about how best to engineer social networks to sustain PA. To improve procedures for building networks that shape PA as a normative behavior, there is a need for more specific hypotheses about how social variables influence PA.
