BCAT (Body Composition Assessment Tool) is a decision-support tool developed for sports and health professionals who assess body composition (BC) in athletes.

The app guides you step by step through a structured evaluation of whether it is appropriate to proceed with a BC assessment, based on recommendations from the IOC consensus on Relative Energy Deficiency in Sport (REDs).

HOW IT WORKS
You answer a series of yes/no questions organized across eight steps:
• Preparation
• Starting the assessment
• Choice of method
• Data collection
• Interpretation of data
• Reporting of data
• Communication of data
• Monitoring

Along the way, you receive color-coded guidance:
🟢 Green – continue to the next step
🟡 Yellow – be attentive, consider action before continuing
🔴 Red – do not proceed until the issue has been resolved

WHO IS IT FOR?
BCAT is designed for sports and health professionals involved in assessing body composition in athletes — not for athletes to self-assess.

Important: The app is a support tool and does not replace professional, medical, or ethical judgment. Use of the app should be part of a holistic assessment carried out by relevant professionals.

PRIVACY
The app requires no login or personal information. Your answers are processed locally on your device. When you finish a review, the app may send an anonymous result status (e.g. whether the assessment was completed or stopped) for statistics and further development of the app — no names, emails, or other identifying information is collected.

ABOUT THE PROJECT
BCAT was developed as a bachelor's project in the Information Systems program at Østfold University College, commissioned by Therese Fostervold Mathisen. The guidelines in the app are based on:

Mathisen, T. F., Ackland, T., Burke, L. M., Constantini, N., Haudum, J., Macnaughton, L. S., Meyer, N. L., Mountjoy, M., Slater, G., & Sundgot-Borgen, J. Best practice recommendations for body composition considerations in sport to reduce health and performance risks.

Available in Norwegian and English.
