Abstract:
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.

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
