Background: Personalized approaches to behavior change to improve mental and physical health outcomes are needed. Reducing the intensity, duration, and frequency of stress responses is a mechanism for interventions to improve health behaviors. We developed an ambulatory, dynamic stress measurement approach that can identify personalized stress responses in the moments and contexts in which they occur; we propose that intervening in these stress responses as they arise (ie, just in time; JIT) will result in positive impacts on health behaviors.

It also evaluated perceived accountability to a primary care provider for weight loss as a moderator and study engagement (operationalized as weeks logged into the study website) as a mediator of these relationships. Participants with complete data for all model variables ( = 428) were included.

- The study aimed to analyze how antiphase trunk motion affects quiet stance stability without changes in visual or surface conditions.
- Wearing a rigid orthotic brace that limited trunk motion, researchers compared sway characteristics across different brace conditions.
- Findings revealed that allowing antiphase motion reduced trunk and leg sway velocities and highlighted the relationship between trunk movement and ankle torque, suggesting that this motion is crucial for maintaining balance, especially in predicting postural issues due to various factors.
Article Synopsis
- This study investigates how well stroke survivors in the U.S. follow physical activity recommendations compared to myocardial infarction survivors and healthy adults, using data from a national survey between 2011 and 2019.
- Results show that adherence rates among stroke survivors varied by year, with rates of 75.4%, 40.2%, and 69.2% for the 2011, 2014, and 2021 guidelines respectively, while MI survivors and healthy adults had lower rates of 42.7% and 72%.
- Older stroke survivors (≥65 years) adhered better to the latest 2021 recommendations than younger ones, and non-Hispanic Black survivors showed lower adherence rates even after adjusting for
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.
