Sciatica is a medical condition characterized by pain going down the leg from the lower back.[1] This pain may go down the back, outside, or front of the leg. Typically, symptoms are only on one side of the body. Certain causes, however, may result in pain on both sides.
respiratory quotient (RQ) the ratio of the volume of expired carbon dioxide to the volume of oxygen absorbed by the lungs per unit of time. Called also respiratory exchange ratio (above).
1 Respiratory Exchange Ratio Respiratory Quotient (RQ) reflects the composition of fuels oxidized by the cells during exercise. At the cellular level, RQ is the volume of CO 2 (VCO 2) produced divided by the volume of oxygen consumed (VO 2) during the same period of time.Since these values are measured at the mouth and not in the lungs, R or Respiratory Exchange Ratio is the term utilized to represent fuel oxidation by indirect calorimetry.When an individual is utilizing 100% carbohydrate for energy, R = 1.0.For fats, R ~ 0.7.ince these values are measured at the mouth and not in the lungs, R or Respiratory Exchange Ratio is the term utilized to represent fuel oxidation by indirect calorimetry.
