ALL YOU NEED TO KNOW ABOUT THE PLUS 2.0
Discover advanced muscle oxygen monitoring with Train.Red PLUS 2.0. Featuring six independent NIRS channels and 100 Hz sampling, PLUS 2.0 delivers detailed physiological insights for coaches, sports scientists and performance laboratories.
Technical Specifications
Train.Red PLUS 2.0 is an advanced wearable muscle oxygen sensor designed for professional monitoring and physiological analysis.
- Technology: Near-Infrared Spectroscopy (NIRS)
- Measurement Channels: 6 independent NIRS channels
- Sampling Rate: 100 Hz
- Measurement: Multi-depth tissue monitoring
- Parameters: SmO2%, O2Hb, HHb, tHb and HbDiff
- Connectivity: Support for 10+ sensors connected to one device
- Software: Train.Red App and Coaching Platform
- Reporting: Automated testing and lab reports
What are the benefits of six NIRS channels?
PLUS 2.0 uses six independent NIRS measurement channels to capture detailed muscle oxygen information across different tissue depths.
Compared with a single-channel measurement system, this provides additional physiological information for advanced analysis.
This makes PLUS 2.0 particularly suitable for performance laboratories, researchers and professional coaches seeking detailed muscle oxygen data.
What does the 100 Hz sampling rate mean?
A sampling rate of 100 Hz means the sensor can collect measurements 100 times per second.
This high temporal resolution supports detailed analysis of rapidly changing muscle oxygen responses during exercise.
It can be particularly useful when studying transitions between exercise intensities, interval training and recovery periods.
Which physiological metrics does PLUS measure?
PLUS 2.0 provides several muscle oxygen and hemoglobin metrics:
- SmO2: Muscle oxygen saturation, expressed as a percentage.
- O2Hb: Oxygenated hemoglobin.
- HHb: Deoxygenated hemoglobin.
- tHb: Total hemoglobin.
- HbDiff: Difference between oxygenated and deoxygenated hemoglobin.
Together, these measurements provide a more detailed picture of local muscle oxygen dynamics.
Is the Train.Red App included?
Yes. Train.Red PLUS 2.0 includes access to the Train.Red App without a mandatory subscription.
The app supports visualization of muscle oxygen data, physiological interpretation, athlete monitoring and performance analysis.
Train.Red also offers coaching and reporting tools for structured performance testing.
Which devices and platforms are compatible?
PLUS 2.0 integrates with the Train.Red App and its associated coaching platform.
Train.Red describes BLE and ANT+ connectivity within its sensor range.
Compatibility with specific smartphones, operating systems, sports watches and third-party applications should be verified before purchase.

FYER vs. FYER PRO vs. PLUS 2.0: What's the difference?
Train.Red offers three sensor solutions designed for different levels of physiological monitoring.
| Feature | FYER 2.0 | FYER PRO | PLUS 2.0 |
|---|---|---|---|
| Sampling Rate | 10 Hz | 100 Hz | 100 Hz |
| NIRS Design | Line sensor | Line sensor | 6 channels |
| SmO2 | Yes | Yes | Yes |
| Full Hb Profile | No | Yes | Yes |
| Primary Use | Everyday training | Advanced analysis | Research & labs |
FYER 2.0 is suitable for athletes starting with muscle oxygen monitoring.
FYER PRO adds high-frequency measurement and additional hemoglobin metrics.
PLUS 2.0 provides six-channel NIRS measurement for detailed professional and research-oriented applications.
SmO2 vs. Heart Rate: What's the difference?
Heart rate reflects the body's cardiovascular response to exercise.
Muscle oxygen saturation (SmO2) provides information about oxygenation in the measured muscle.
These measurements are complementary. Monitoring both can help athletes and coaches better understand physiological responses to training.
Who should choose Train.Red PLUS 2.0?
PLUS 2.0 is designed for users requiring detailed physiological monitoring capabilities.
- Sports scientists and researchers
- Exercise physiology laboratories
- Professional coaches
- High-performance sports centers
- Professional sports teams
- Advanced performance practitioners
For athletes who primarily need straightforward SmO2 monitoring, FYER 2.0 may be a more suitable starting point.
