Biological variability in maximum aerobic power.
Abstract
The biological variation in maximum aerobic power (V O2max) was examined in four trained females and one trained male. An average of 8-20 repeat VO2max treadmill tests over a 2-4 wk period were performed on each subject (80 total tests). Biological variation (Si) in VO2max was computed as the standard deviation for the VO2max values for each individual, after subtracting net technological error (Se). Technological error was computed for each piece of equipment as the standard deviation of multiple trials. Results revealed that Si + Se amounted to +/- 5.6%. Biological variability accounted for 90% or more of this variability, while technological error accounted for less than 10%. In light of the magnitude of biological variation for VO2max, the necessity for securing control data when attempting to study training effects is pointed out.

There is considerable within-individual and between-individual heterogeneity in acute psychophysiological responses to the same acute physical exercises and in long-term adaptations to the same physical training.
“Since every human is unique, there is a considerable amount of within-individual (intra-individual) (Katch et al., 1982; Coggan and Costill, 1984; Bagger et al., 2003; Skurvydas et al., 2010; Faude et al., 2017; Chrzanowski-Smith et al., 2019; Voisin et al., 2019) and between-individual (interindividual) heterogeneity (Karavirta et al., 2011; Chmelo et al., 2015; Bonafiglia et al., 2016; Greenham”

The same physical exercises induce very heterogeneous outcomes across individuals.
“However, growing evidence shows that the same physical exercises induce very heterogeneous outcomes across individuals.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
