Masimo MightySat
When the majority of the pack in cycling can compete at the same level, winning the race comes down to the marginal gains. Before Road Worlds last year I added a new, extremely valuable tool to my collection... the MightySat Fingertip Pulse Oximeter! Now I am still pretty new to all of the science behind the functions on it, but basically what it does is measures your pulse rate, oxygen saturation, perfusion index, respiration rate and pleth variability index. The pulse rate is pretty self explanatory; how many times your heart beats per minute. The fitter you are, the lower your resting heart rate will be, because more blood is pumped with each pulse; your heart is strengthened to work more efficiently :) One of the most useful measurements I found was the oxygen saturation. It is the measurement, as a percentage, of oxygen in the arterial blood. Higher levels of blood oxygen, means that more oxygen is being transported around the body, thus providing more oxygen to your muscles. ...
