1. Oxygen is KEY to everything in your body, but it is also CENTRAL to AVERAGE human health and PEAK performance. It drives everything from BREATHING, to molecular signaling pathways, and combines so much more.

  2. NIRS can be used for specific muscles in that oxygen chain, but not whole-body processes. Yet, they can help us understand the path the oxygen has taken for your muscles during specific exercises (e.g. maximal blood volume as a marker for capillary adaptation).

  3. Overtraining is not often the problem. More often than not you might not have enough recovery, or not the right type of training, or there are nutritional issues. Thus, consider “re-”thinking of these problems as MALADAPTATION.
