OXY4 is the first to offer you a device for monitoring multiple parameters for different areas of performance diagnostics.
The reliability and high quality of the measuring data, as well as their easy interpretability are taken for granted by us. In this way, we make performance diagnostics, which were hitherto reserved to sports medicine and the professional fitness sector, accessible to every athletically ambitious person.
Below, you will find an overview of the measured parameters.
SmO2 – Muscle Oxygen Saturation
This parameter shows you the level of oxygen-saturated blood in the muscle tissue.
The circulatory system provides the muscle with arterial blood (red) that is saturated with oxygen. In order to function, the muscle tissue uses the oxygen and leaves the blood less oxygenated. The veins (blue) transport the blood back to the lungs where it is saturated with oxygen again.
When the oxygen supply of the muscle is sufficient, the muscles work in the so-called aerobic zone: at this point, metabolic processes are functioning at their respective optimum, muscle tissues grow larger and the performance is enhanced. However, if the energy requirement of the muscle tissue surges due to an increasing strain without a rise in oxygenation levels, cellular processes reach the anaerobic zone. During this energy turnover, lactate (salt of lactic acid) and hydrogen ions are produced that lead to a reduction of the pH value of the blood. The body over acidifies and the physical performance cannot be sustained. The muscles get tired rapidly and the activity would need to be stopped.
For that reason, the continuous monitoring of the muscle oxygenation is of great importance for an effective training strategy. To achieve maximum efficiency during a training session, the workout needs to be in the upper limit of the aerobic zone – without crossing the line to anaerobic processes.
THI – Tissue Hemoglobin Index
The THI indicates how high the concentration of hemoglobin in the monitored tissue is.
PI – Pulse Index (Pulse Strength)
The PI shows the strength of the pulsation of the hemoglobin in the muscle at the measuring site. It is influenced by the heart’s pump output.
PR – Pulse Rate
This parameter provides you with the number of pulse rates per minute.
RR – Respiratory Rate
This rate indicates how many breaths are taken per minute.
PRV – Puls Rate Variability
This parameter provides information about the variability of the time interval between two pulse beats. In contrast to heart rate variability (HRV), pulse rate variability (PRV) is not measured directly at the heart, but at other locations of the body, e.g. wrist, carotid artery or as with the use of TrainOXYTM or OXY DR2 at the musculature under load. As a rule, the pulse rate and the heart rate and the respective variability are often the same, which is why the term heart rate has become established in general speech use as well as in the area of sports. Especially in the case of higher physical activity, there is the possibility that not every heart contraction (systole) triggers a pulse wave.
