Statistical analysis results of post - pre training differences: NMR body mass, lean mass, fat mass, % lean mass, % fat mass; difference between terminal and pre-training NMR mass at 1W and 2W of endurance training; absolute VO\(_2\)max; relative VO\(_2\)max; and maximum run speed.

PRE_POST_STATS

Format

An object of class data.frame with 90 rows and 21 columns:

response

character; the measurement being tested.

age

factor; the age of the rat at the beginning of the training protocol. Levels: "6M" (Adult) and "18M" (Aged).

sex

factor; the sex of the rat with levels "Female" and "Male".

group

factor; exercise training group. Either "SED" (sedentary) or the number of weeks of training ("1W", "2W", "4W", "8W").

estimate_type

character; interpretation of the value in the estimate column. Either "(post - pre) mean" (mean of the paired (post - pre) differences) or "signed mean (post - pre) rank" (the signed mean ranks of the (post - pre) differences).

estimate

numeric; the value of the estimate, as described by estimate_type.

SE

numeric; the standard error of the estimate.

lower.CL

numeric; lower bound of the 95% confidence interval.

upper.CL

numeric; upper bound of the 95% confidence interval.

statistic_type

character; the type of statistical test. Either "t" (Student's t-statistic) or "W" (Wilcox's W-statistic).

statistic

numeric; the value of the test statistic.

p.value

numeric; the p-value associated with the statistical test.

p.adj

numeric; the Holm-adjusted p-value.

signif

logical; TRUE if p.adj < 0.05.

model_type

character; the statistical model used for testing. Either "lm" (linear regression) or "wilcox.test" (Wilcoxon test).

formula

character; the model formula. Includes the response variable, any transformations, and predictors.

family

character; the probability distribution and link function for the generalized linear model.

weights

character; if reciprocal group variances were used as weights to account for heteroscedasticity (nonconstant residual variance), this is noted here.

obs_removed

character; if any observations were omitted during the analysis, they are listed here.
