Last but not least fro today.
 We just shipped out a full production of  the new MOXY. Why.
 In the past  many  progressive coaches mailed us and we had great discussion about ECGM and the idea of Limiter and compensator.
 The main problem was, that the equipment to  look live  oxygenation trends and move them into context with  the other physiological systems like respiration and cardiac information was  simply a very expensive  idea and even many  universities   hesitated to but this equipment.
 In studies like rowing or  cross country skiing alone the idea to  test left and right arm and at the same time left and right leg would explode your year budget for  equipment.

 Well now we just had a Ice hockey coach  ordering 8  MOXY's  so he  can use them either on 8 athletes at the same time and see on his screen the individual needed load or rest period  or he can look at  both legs  and or even legs and core at the same time.
 He still is  nearly   half Price to a one  NIRS unit option in the current available tools.
 Fortiori with its MOXY production opens a futuristic  way  that you and I  can go out today and workout  live individual at the right intensity as  we may have planned for today's workout. If you combine   other bio markers like HR and RF to it and pair it with a performance  info like Watt on a bike or speed or time in swimming or running or rowing  than you have now your small lab on your leg and have information only available in the past for some selected groups of researchers.
 Here a nice info on what we  can do and why it works.

The use of near infrared spectroscopy in sports medicine.


Department of Biomedical Sciences and Technologies, University of L'Aquila, L'Aquila, Italy.


In the last 15 years the study of the human muscle energetics in sports medicine underwent a radical change thanks to the progressive introduction of non-invasive techniques, including near infrared (NIR) spectroscopy (NIRS). NIR light (700-1000 nm) penetrates skin, subcutaneous fat and underlying muscle, and is either absorbed (by oxy- and deoxy-haemoglobin) or scattered within the tissue. NIRS is a non-invasive and relatively low cost optical technique that is becoming a widely used instrument for measuring muscle O(2) saturation and changes in haemoglobin volume. Muscle O(2) saturation represents a dynamic balance between O(2) supply and O(2) consumption in the small vessels such as the capillary, arteriolar and venular bed. NIRS offers the advantage of being less restrictive than (31)P-magnetic resonance spectroscopy with regard to muscle performance and more comfortable and suitable for the monitoring, with high temporal resolution (up to 10 Hz), of multiple muscle groups. The aim of this review is to summarise the NIRS instrumentation and the measurable parameters, the role of NIRS in muscle exercise physiology, and the applications in sports medicine. The advantages and the problems of NIRS measurements, in resting and exercising skeletal muscles, are reported. The results of several studies suggest that NIRS is a powerful tool for being applied successfully in sports medicine. NIRS can objectively evaluate muscle oxidative metabolism in athletes and its modifications following potential therapeutic strategies and specific training programs.
