What is Phase Angle?

How does it work?

Bodystat’s Phase Angle is a direct measurement, (not a calculation using equations) of your cell membrane.

When the cell membrane (or capacitor) loses its ability to function efficiently (ie in cases of malnutrition or disease) it effectively loses its ability to store electrons and can no longer function as an effective capacitor. This is what the Phase Angle picks up. The Phase Angle is the measurement of the functionality of the cell membrane, ie how well our battery is working. If there are leaks in the cell membrane the ability of the cell membrane to hold on to voltage will decrease, thus the Phase Angle will decrease.

A high Phase Angle shows good health, and a low Phase Angle shows a decline in health status.

Applications

Phase Angle is currently used in hospitals to monitor nutritional assessment and is recognised as a general ‘wellness’ biomarker, however this measurement has found its way into the fitness industry as there is a significant statstical correlation between Phase Angle and muscle strength (lean muscle mass).

As well as the numerous benefits in a clinical setting, Phase Angle is increasingly becoming known as an indicator for muscle strength and nutritional status..

This has potential for a wide variety of potential applications such as sports injury, rehabilitation and tracking of strength training.

A study on elite Brazilian athletes depicted a strong correlation between Phase Angle and increased muscle strength, and in fact noted that “intense physical training may affect cellular membrane stability” as shown by the Phase Angle marker. This has led to the question whether Phase Angle can actually predict injury?  (Proceedings of the Nutrition Society (2008), 67 (OCE8), E332)

The Slovenian Olympic Rowing Team also used Phase Angle in Rio as part of their training, and it was found that an unusually high Phase Angle (>10) indicated over-training, and poor performance due to muscle fatigue.

 

In Summary

When the cell membrane (or capacitor) loses its ability to function efficiently (i.e. in cases of malnutrition or disease) it effectively loses its ability to store electrons and can no longer function as an effective capacitor. This is what the Phase Angle picks up. The Phase Angle is the measurement of the functionality of the cell membrane, i.e. how well our battery is working. If there are leaks in the cell membrane the ability of the cell membrane to hold on to voltage will decrease, thus the Phase Angle will decrease.
A high Phase Angle shows good health, and a low Phase Angle shows a worse status of health.

An individual’s Phase Angles are very different, and as it stands at the moment, there are no standardisations for population groups.
