The Incidental and Planned Exercise Questionnaire (IPEQ) is a valid tool for measuring moderate- to vigorous-intensity physical activity (MVPA) in older adults. This questionnaire is useful for both surveillance and intervention studies in aging research.
Area of Science:
- Gerontology
- Exercise Science
- Public Health
Background:
- Physical activity assessment is crucial for older adults' health.
- Existing questionnaires may not adequately capture incidental and planned exercise.
- The Incidental and Planned Exercise Questionnaire (IPEQ) was developed for aging research.
Purpose of the Study:
- To evaluate the criterion validity of the IPEQ.
- To assess the responsiveness of the IPEQ in older adults.
- To determine the IPEQ's utility in aging research.
Main Methods:
- 315 community-dwelling inactive older adults participated.
- Criterion validity was assessed using accelerometers (ActiGraph GT1M).
- Responsiveness was measured by comparing IPEQ change in intervention vs. control groups.
Main Results:
- IPEQ-MVPA showed moderate correlations with accelerometer measures (0.26-0.35).
- IPEQ demonstrated significant correlations with light-intensity physical activity.
- The 12-month responsiveness for planned walking was 0.44.
Conclusions:
- The IPEQ is a practical and valid measure for assessing physical activity in older adults.
- It is suitable for use in surveillance and intervention studies.
- Lower correlations for incidental activities may be due to their light intensity and low ambulatory component.

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...
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.

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
