KEY-FEATURES FOR YOU

FASTEST SPORT TEST

Skip the masks and labs. Here's the simplest muscle oxygen-based fitness test you can do anytime, anywhere. It's the cornerstone of your training advice for athletes. Take the course to learn how.

Improve your athletes

Enhance your coaching strategies with our pacing feature, ensuring optimal performance from your athletes while prioritizing their fitness and well-being.

Muscle stamina / aerobic capacity

The longer your body can maintain a balance in the supply of oxygen by your heart and lungs, and the demand of oxygen by your muscles to create energy, the better your muslce stamina. Use our Muscle States 2 or the Supply & demand feature.

Muscle efficiency / Critical power

Your muscles' ability to sustain medium-intensity, tempo efforts. In this so-called 'grey' training domain, your muscles are very efficient with oxygen.

MUSCLE POWER / ANAEROBIC CAPACITY

Your muscles' ability to perform high-intensity, sprint efforts. You're mainly using very strong, inefficient energy pathways. You'll be out of breath and need to recover.

IN APP FEATURES

The sensor measures the oxygen saturation and (de-)oxyhemoglobin changes in your muscle and converts this data into real-time key features with the help of AI.

Profile + organisation

Create multiple profiles and choose your level. You can also include your team or organization.

live feedback features

Our advanced algorithm monitors muscle recovery and intensity levels in real-time, displaying oxygen supply and demand visually through graphs or live view. Combine more than 4 sensors at once.

Post session overview

In the app, for each sensor, you can view muscle oxygen levels over time and distance after every session. This includes average time spent in different muscle states and smart rest intervals during training.

Laps & timed sections

Analyze lap intensity to optimize interval training and enhance muscle efficiency for athletes.

WE RECOMMEND 4x TRAIN.RED FYER SYSTEM

Endurance trainers and coaches, we highly recommend opting for the 4x FYER sensor. The FYER stands out as the most versatile and lightweight Muscle Oxygen system globally. With four sensors, you can assess left-right differences and multi athlete monitoring. Purchasing the set of four sensors entitles you to a substantial discount. This comprehensive package includes the FYER sensor, software, and all necessary accessories.

WHAT MAKES TRAIN.RED DIFFERENT

Train.Red uses Near InfraRed Spectroscopy (NIRS) to measure your muscles. This tech is not new, our scientific partner Artinis Medical Systems has over 20 years of research experience with this tech and helped us develop the next generation of wearable Muscle Oxygen Sensors.

Not only are our sensors the most advanced on the market. We also translate your data into easy to understand, actionable insights. Making it easier than ever to use muscle oxygen data in your daily training or do tests without a lab setting.

Christian Pirri

Athlete & Coach

I use Train Red regularly, on the one hand to make pause control between intervals more efficient but also to control increased SMO2 saturation in the muscle during aerobic training sessions.

Gommaar d'Hulst

The days of bulky, complicated devices are over. Train.Red has broken new ground with user-friendly sensors. It can be effortlessly attached, and the app shows the data in a simple GUI that anyone can comprehend.

Roman Fomin

PhD Director of Sport Science UFC

We (UFC) are taking performance improvement to the next level, using real-time energy systems assessment on both systemic and peripheral levels.

Sarah Thivent

Sports scientist

As a researcher, I needed to measure muscle oxygen saturation (SMO2) during the cycle ergometer tests of my patients. I then discovered Train.Red, I use it every week and it meets my needs very well. It's a simple tool that provides very important information if one is aiming for improvement or research purposes.
