Cardio respiratory fitness can be measured by the​

Cardiorespiratory fitness is measured through VO2max testing. VO2max is essentially a measurement of the maximum amount of oxygen that your body is capable of consuming to generate energy that can be used at the cellular level.

Cardiorespiratory endurance is measured by maximum oxygen uptake (VO2 max) and how it's used during intense exercise. Higher amounts of oxygen uptake show that you're using more oxygen and that your cardiorespiratory system is functioning efficiently.

the answer is nerve impulses.
