What PACER Measures

What PACER Measures

Unmatched accuracy through
Real breath analysis

PACER measures your actual breathing, providing performance metrics far more accurate than any other wearable device. It even delivers insights that other devices simply cannot, setting a new standard for precision and reliability in fitness tracking.

Performance Metrics:
VO2max

VO2max (Maximum Oxygen Uptake) is the maximum amount of oxygen your body can utilize during intense exercise. It is widely regarded as the gold standard for measuring aerobic fitness and endurance capacity.

A higher VO2max indicates greater efficiency in delivering oxygen to your muscles, allowing you to sustain physical activity for longer and at higher intensities. It's a critical metric for assessing overall cardiovascular and respiratory efficiency.
Running Economy

Running Economy refers to the amount of energy your body uses to maintain a certain running speed. It's a measure of how efficiently you convert oxygen into movement during running.

Better running economy means you use less energy (and oxygen) to run at the same speed, allowing you to run farther or faster with the same effort. Factors influencing running economy include biomechanics, muscle efficiency, and physiological adaptations. It's a crucial metric for optimizing performance, especially in long- distance running.
Lactate Threshold

Lactate Threshold (LT) is the intensity where lactate builds up faster than it can be cleared, marking the shift from aerobic to anaerobic effort.

LTP (Lactate Threshold Pace) is the running pace at this threshold, crucial for optimizing endurance and pacing strategies during training and races. Training at your LTP helps improve performance and sustain higher intensities for longer.

Respiratory Metrics:

Imagine knowing exactly how efficiently your body delivers oxygen to your muscles and manages carbon dioxide during exercise. With PACER's advanced tracking, you gain insights that go beyond the surface, helping you breathe better, train smarter, and push your limits.
Biomechanical Metrics:

Biomechanical Metrics provide detailed insights into your running form and efficiency, helping you refine your technique and reduce the risk of injury. These metrics analyze how your body moves, offering a deeper understanding of your performance mechanics.
Energy Metrics:

Energy Metrics reveal how your body fuels itself during exercise, providing actionable insights to optimize your training and performance. PACER's advanced testing measures your energy dynamics and pinpoints the pace where fat burns most efficiently, helping you maximize results.
