Environmental Resources in Maintenance of Physical Activity 6 Months Following Cardiac Rehabilitation

Facilitators and barriers of initiation and maintenance of physical activity among people with coronary heart disease: a qualitative study

PURPOSE

We aimed to describe the facilitators and barriers of physical activity for patients with coronary heart disease.

METHODS

A qualitative descriptive study using semi-structured interviews was conducted with 15 participants with coronary heart disease. The interview guide was developed based on a multi-theory model. Interviews were audio-recorded, transcribed verbatim, and analyzed using a thematic analysis.

RESULTS

Two main themes were identified: facilitators of initiation and maintenance of physical activity (behavioral motivation, perceived benefits, behavioral confidence, supportive physical environment, positive emotional experience, self-regulation, supportive social environment, illness perception, and excellent self-control), barriers of initiation and maintenance of physical activity (perceived barriers, restricted physical environment, psychological distress, insufficient social support, and poor self-control).

CONCLUSIONS

This study presents an in-depth theory-based exploration of facilitators and barriers to initiating and maintaining physical activity among people with coronary heart disease. Relevant factors should be taken into account to increase their effectiveness when designing the target interventions to encourage a physically active lifestyle in this population.

Pilot randomized controlled trial of the Yoga for HEART intervention in community-dwelling older adults

Physical activity reduces cardiovascular risk; however, many older adults do not engage in recommended levels. Theory-based interventions supporting motivation for physical activity are limited. This pilot study evaluated the feasibility of Yoga for Health Empowerment and Realizing Transformation (HEART), a theory-based intervention combining motivation and yoga-based physical activity. Feasibility was addressed as acceptability, demand, implementation fidelity, and limited efficacy in promoting physical activity, cardiovascular health, and mechanisms of action. Sedentary older adults (m = 65 years old, sd = 8.5) were randomized to Yoga for HEART (n=8) or Active Control (n=7) conditions. Yoga for HEART was: (a) acceptable, (b) retention 73%, (c) implemented as planned. A significant main effect for body mass index (BMI) was found in Yoga for HEART participants (p = .02). No significant effects were found for physical activity, other cardiovascular outcomes, or mechanisms of action. Yoga for HEART is feasible and recommended for further testing.

Factors Influencing the Impact of Depressive Symptoms on Physical Functional Capacity After Cardiac Rehabilitation

PURPOSE

This study aims to determine (1) if depressive symptoms in the year following completion of cardiac rehabilitation impact physical functional capacity and (2) if exercise, perceived benefits and barriers, self-efficacy, and social support moderate this relationship.

DESIGN

This longitudinal correlational secondary data analysis included 379 cardiovascular rehabilitation patients.

METHODS

Participants completed measures of depression and potential moderating variables at baseline, 2 months, 6 months, and 12 months and 6-minute work test at baseline and 12 months and wore heart rate monitors to measure exercise for 12 months.

FINDINGS

Poorer physical functional capacity was predicted by depressed mood score. This relationship was moderated by the percentage of time exercising in target heart rate zone and family support of exercise, but not by perceived benefits and barriers or self-efficacy for exercise.

CONCLUSIONS

Depressive symptoms negatively impact physical functional capacity, and this relationship is moderated by family support and the percentage of time exercising in target heart rate zone.

CLINICAL RELEVANCE

Improving percentage of time exercising in target heart rate zone may be a mechanism by which patients with depressed mood can optimize physical functional capacity.

Mediators of physical activity adoption and maintenance among breast cancer survivors

The purpose of this study is to explore the mediators associated with physical activity (PA) within the adoption and maintenance phase of a PA intervention trial among breast cancer survivors. Overall, 192 breast cancer survivors (average age = 55.9 years) were randomized to an Intervention or Control group. Both groups received 8 calls in the first 3-months, 3 monthly calls, and then entered a no-contact maintenance phase for the remaining 6-months. Assessments were completed at baseline, 3-months, 6-months and 12-months. On average, participants were 55.9 years of age (SD = 9.8) and 2.9 years since diagnosis (SD = 2.2). In the adoption phase, all significant univariate mediators (self-efficacy, cognitive and behavioral processes and decisional balance cons) were included in the multivariate model. Results suggest self-efficacy (ab = 13.56, SE = 7.04) and behavioral processes (ab = 36.10, SE = 12.22) were significant for PA adoption. No mediators were identified in the maintenance phase. In the adoption phase, there were significant indirect effects of group on PA adoption through self-efficacy and behavioral processes. There were no indirect effects of group on PA maintenance.

ReadySteady intervention to promote physical activity in older adults with Parkinson's disease: Study design and methods

The main motor impairments of gait and balance experienced by people with Parkinson's disease (PD) contribute to a sedentary lifestyle, resulting in poor physical conditioning, loss of functional independence, and reduced quality of life. Despite the known benefits of physical activity in PD, the majority of older adults with PD are insufficiently active. Few studies incorporate behavioral change approaches to promoting physical activity in PD. The main goal of this research is to foster community mobility in older adults with PD by promoting physical activity and improving gait patterns using a theory-based behavioral change intervention. The ReadySteady intervention combines wellness motivation theory with polestriding physical activity, which has been shown to be beneficial for people with PD. The intervention will be tested using a randomized controlled design, including inactive older adults diagnosed with PD. Participants will be randomly assigned the 12-week ReadySteady intervention, 12-week polestriding, and education intervention, or 12-week education intervention. Thirty-six older adults with PD will participate in each of the interventions. Level of physical activity, clinical scores, quantitative measures of gait and balance control, and motivational variables for each intervention will be measured at three time points: pre-intervention, post-intervention (12 weeks), and follow-up (24 weeks). If the intervention is beneficial, it may serve as a sustainable addition to current practice in health promotion efforts serving the PD population.
