[Freiburg Questionnaire of physical activity--development, evaluation and application]

Area of Science:

• Public Health
• Exercise Science
• Epidemiology

Context:

• Assessing physical activity is crucial for public health.
• Existing methods may have limitations in population studies.
• Understanding activity patterns informs health interventions.

Purpose:

• To design and validate a questionnaire for health-related physical activity.
• To evaluate the reliability and validity of the instrument.
• To assess physical activity patterns in an adult population sample.

Summary:

• The study developed a reliable questionnaire for physical activity assessment.
• Test-retest reliability was high over two weeks and six months.
• Validity was confirmed by correlating activity with maximum oxygen uptake and self-perception.
• Median physical activity was 9.2 hours/week, dominated by low-to-moderate intensity activities.
• Age and gender significantly influenced activity patterns.
• 40% did not meet Paffenbarger's 2000 kcal/week recommendation; 63% fell short of ACSM's 1000 kcal/week training guideline.

Impact:

• Provides a validated tool for future physical activity research.
• Highlights a significant portion of the adult population failing to meet physical activity recommendations.
• Identifies key demographic factors influencing activity levels.
• Informs targeted public health strategies to promote physical activity.
