In Cardiorespiratory Fitness (CRF) tests, you usually measure heart rate, lung capacity, and blood flow, but muscle performance is often forgotten. With Train.Red sensors, you can easily measure muscle oxygen and include it in your tests or focus just on muscles.

The Fick principle tells us that VO2max equals the amount of blood pumped by the heart, times the oxygen your muscles take from the blood. Train.Red helps you measure how much oxygen your muscles are using.

Like heart rate or lactate, hemoglobin changes can help you:
- Track performance and identify key training points
- Monitor progress
- Set the right training intensity and pacing
- See how your training is working

For sports tests or research, all you need is a Train.Red sensor, a smart device, a strap, and a patch to keep everything in place and block outside light. You’ll be ready in just one minute!

WODSCIENCE THRESHOLD TEST


Warm-up
Initial phase to set the baseline and get your muscles ready for action.
Muscle Stamina
Muscle State 2 & Zone 2 Training
Your muscles' ability to sustain low-intensity, endurance efforts. Breathing stays easy and comfortable because your muscles are getting plenty of oxygen.
Muscle Efficiency
Muscle State 3 & Zone 3 Training
Your muscles' ability to maintain medium-intensity, tempo efforts. In this "grey zone," your muscles use oxygen very efficiently to keep you going.
Muscle Power
Muscle State 4-5 & Zone 4 Training.
Your muscles' ability to perform high-intensity, sprint efforts. In this zone, your muscles rely on strong but inefficient energy pathways, leaving you out of breath and in need of recovery.
Muscle recovery
After exercise, your muscles need less oxygen, but your heart keeps working hard! Oxygen and nutrients help repair and restore your muscles. The faster this happens, the better your recovery will be!
We recommend
Clinics and sports labs choose the 4 PLUS sensor system. The PLUS is the most advanced and fastest Muscle Oxygen system worldwide, offering deeper muscle measurements than any other system. With four sensors, you can assess left-right differences and establish a reference area.
