MOXY - Part 1 Principles of Placement
The video covers best practices for placing the Moxy Monitor to obtain reliable muscle oxygen saturation (SmO₂) data. Emphasis is placed on selecting active muscles, measuring tissue thickness to avoid signal interference, and ensuring consistent device placement on the muscle belly for accurate and repeatable readings.
MOXY - Part 3 Assessment with Moxy
The video discusses using the Moxy Monitor to assess physiological responses during exercise, focusing on muscle oxygen saturation (SmO₂). Key points include identifying specific breakpoints in SmO₂ to determine shifts in muscle oxygen supply and demand, as well as utilising this information to guide training intensity and track physiological readiness.
Artinis - Muscle Near Infrared Spectroscopy, How and Why? (by Prof. Chris Cooper)
In this webinar, Prof. Chris Cooper from the University of Essex explains what NIRS is, how it can practically be used to measure the muscle, and what analysis methods can benefit future muscle NIRS applications.
Artinis - How to setup the PortaMon - NIRS device for muscle oxygenation measurement
The PortaMon is a wearable, wireless near-infrared spectroscopy (NIRS) device to measure muscle oxygenation. It uses a Bluetooth connection, enabling you to record online while the subject is on a running track. PortaMon can also store its data inside for larger distances, ready for downloading afterwards. Although of small and handy size the PortaMon offers many possibilities (and high data quality). Next to the standard concentration changes of oxy-, deoxy- and total haemoglobin, this device also provides a value of tissue saturation index (TSI): the percentage of oxygenated hemoglobin.

MOXY - Part 2 mNIRS Terminology
The video explains terminology related to muscle oxygen saturation (SmO₂) and tissue saturation (TSI), particularly focusing on differences in their measurements and implications. The speaker argues that SmO₂, which measures muscle-specific oxygen saturation, differs significantly from general tissue indices, highlighting the importance of understanding these distinctions when interpreting data.
MOXY - Part 4 Warm up
The video discusses the principles of an effective warm-up, specifically how real-time muscle oxygenation (SmO₂) can be used to assess whether an athlete is adequately prepared. The presenter proposes a two-phase warm-up approach—cardiovascular and muscle preparation—to optimise SmO₂ without inducing fatigue. This method could potentially improve performance by individualising warm-ups based on physiological responses.
Artinis - Introduction to NIRS muscle measurements – Measure muscle oxygenation using Near-Infrared Spectroscopy
Near-infrared spectroscopy (NIRS) is a technology that enables non-invasive measurement of oxygenation in local tissue, for instance muscle. The field of sport Science is one of the first research fields where NIRS found wide use application to get insight in the local muscle oxygen consumption.
