Objectives:
To determine if positive affect is related to the self-reported health and health behaviors of blue-collar women.
Methods:
Analysis of baseline survey data of 1093 women participating in a worksite health promotion intervention at 12 workplaces in 5 rural counties.
Results:
Positive affect was related to women's self-reported health and exercise. Also, positive coping behaviors were related to exercise.
Conclusions:
These findings suggest that incorporating strategies to encourage positive emotional states and positive coping into health promotion interventions might be helpful for improving women's levels of physical activity and overall reported health.

Exercise 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...

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.
Purposes
Assessment of the Cardiovascular System I: Subjective Data
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities
