Objective:
To determine whether a transtheoretical model-based exercise stage-matched intervention (ESMI) has positive effects on the exercise behavior of sedentary patients with coronary heart disease (CHD).
Methods:
The study was a randomized controlled trial with a repeated measures design. Participants (N=196) were randomly allocated to either a conventional (C) group, a patient education (PE) group, or an ESMI group. Exercise behavior was measured by exercise stages of change, exercise self-efficacy, exercise decisional balance, and duration of moderate exercise at baseline, immediate post-intervention, and at 3- and 6-month follow-up.
Results:
Our results showed that the ESMI group demonstrated a more positive shift in exercise stages of change (p<0.01), higher exercise self-efficacy (p<0.01), greater exercise benefits (p<0.01), fewer exercise barriers (p<0.01), and longer moderate exercise duration (minutes/week) (p<0.01) after completion of the 8-week intervention compared with the C and PE groups. These significantly positive effects were maintained at 3- and 6-month follow-up.
Conclusion:
The transtheoretical model-based ESMI had significantly positive effects on the exercise behavior of sedentary CHD patients.
Practice Implications:
It is important to provide a structured education program for CHD patients, preferably guided by the transtheoretical model.

01:26Exercise 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.
Purposes
01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
