Hi Phani!
Since you posted in the Sample Size category: It's one of the four fixed values (α, acceptance range, T/R-ratio, CV). Based on those you calculate power (1–β).
In the study itself, none. But since the value is based on MSE, the higher the CV for any given sample size, the wider the confidence interval.
❝ Intrasubject variability. Is this expected value or calculated.

❝ How does this parameter have pertinence in study performance.
