SCIENCE IN NEUMAFIT

WHY CPET

CPET is a scientific test that quantifies your body’s metabolic response during aerobic exercise — revealing exactly when and how your limits are reached. Traditional training often relies on guesswork or past experience. CPET, on the other hand, uses real breathing data to guide your training with precision. Instead of repeating routines blindly, training based on your own physiology leads to faster, more effective results.

VALIDATION & ACCURACY

PACER has shown remarkably high accuracy when compared to premium lab equipment like COSMED and VO2Master. Error margins are extremely low, with measurement agreement exceeding 98%. The PACER team continues to refine its algorithms and measurement technology — with the goal of delivering even more precise, personalized insights.

OUR AI EDGE

Traditional lab equipment relies on real gas analyzers to directly measure oxygen and carbon dioxide. While accurate, these systems are bulky and expensive — not ideal for everyday use. Neumafit reimagined this entire approach. By combining data from high-precision sensors — including flow sensors, PPG, and IMU — our proprietary AI and GPS-based algorithms deliver detailed, reliable analysis. The result? PACER achieves lab-grade accuracy without the need for gas sensors.

PERFORMANCE INSIGHTS

Many runners obtain data like VO₂max and lactate threshold, but few know how to actually apply it to their training. PACER goes beyond just showing numbers. It provides clear strategies tailored to each user's physiology, including training zones, pace guides, and energy gel timing. As a personalized training coach that supports not just measurement but also interpretation and execution, PACER led 98.4% of users to improved race times or noticeably better running experiences.
