RQ may stand for a number of things but in science it means respiratory quotient. This is a measure which is used in calculations of basal metabolic rate.

How do you calculate respiratory quotient?

The respiratory quotient (RQ) is calculated by dividing the volume of carbon dioxide (CO2) produced by the volume of oxygen (O2) consumed during respiration. The formula is RQ = CO2 produced / O2 consumed. RQ values can vary based on the type of substrate being metabolized; for example, carbohydrate metabolism typically has an RQ of 1.0, while fat metabolism has an RQ around 0.7. This measurement helps to assess metabolic processes and substrate utilization in the body.


What does RQ stand for?

It has many diffrent names. However the one you may come across is: "Request".


Why are vectors RQ and QR not equivalent?

Vectors involve a direction component. So while the magnitudes may be the same, the direction won't be.

How many kilocalories per kg per hour would expend exercising at 6 METS?

The answer to this can only be approximated. To do it, you need to know the oxygen consumption at 6 METS. The standard assumption for this is that 1 MET is 3.5 ml/min/kg of body weight. Now you need to know how many Calories are burned for each ml/min of VO2. This again, is only an approximation, because the answer depends on assumptions about muscle efficiency and fuel burned. When the RQ (ratio of VCO2/VO2) is about 0.8, we burn about 4.8 Cal per liter of VO2 (source: ACSM resource manual). So, here we go: 6 METS = 6 x 3.5 = 21 ml/min/kg of VO2. Assume a 70-kg body weight, this gives VO2 of 1.47 l/min. Now multiply by the KCal factor to get 7 Cal per minute, or 420 Cal per hour. Putting the answer in units per Kg as requested, gives 420/70 = 6 Cal/kg/hour. 6 METS is about 3.5 MPH at 5% grade (brisk walk up slight hill).
