Tidsramme |
|---|---|---|
|
Composition of Stool Micro Biome Diversity and Phylogenetic Distribution at 0 Days, 8 Days and 28 Days
Tidsramme: Baseline, Day 8, Day 28
|
Relative abundance is defined as the proportion of total identified bacteria in a sample that are a given type of bacteria.
As an example a relative abundance of firmicutes equal to 0.9 would mean that 90% of the bacteria identified in a sample are firmicutes

Indirect Calorimetry Data at 0 Day, 8 Days and 28 Days Respiratory Quotient RQ
Tidsramme: Baseline, Day 8, Day 28
|
The respiratory quotient is a ratio between the volume of carbon dioxide exhaled and the volume of oxygen inhaled during respiration.
It typically ranges between 0.7 and 1.0 and is an indicator of metabolic fuel or substrate use in tissues; it must be calculated under resting or steady-state exercise conditions.
A ratio of 0.7 is indicative of mixed fat use, whereas a ratio of 1.0 indicates the exclusive use of carbohydrates
