Can indirect calorimetry and accelerometry be used to assess energy expenditure in healthy and unhealthy population? A systematic review and meta-analysis

Key Points

• The aim is to compare the effectiveness of indirect calorimetry and accelerometry in measuring energy expenditure across populations.
• Conducted a systematic review and meta-analysis.
• Compared measurements from indirect calorimetry and accelerometry.
• Assessed reliability in both healthy and unhealthy subjects.
• Accelerometers showed higher reliability when measuring energy expenditure during physical activity.
• The reliability of accelerometers increased significantly in healthy subjects compared to unhealthy subjects.
