- a Revolutions/day (distance), 1-min intervals/day (time, cumulative 1-min intervals in which at least one revolution was recorded), average running speed (total revolutions/time spent running), and maximum running speed (highest number of revolutions in any 1-min interval within a 24 h period). Data were from general linear model [Univariate GLM ANOVA (SPSS, Chicago, IL)] and transformed
- b as necessary to improve normality of residuals [11]
- c Group represents the following maternal experimental conditions: no exercise (standard mouse cage), post-weaning only exercise (access to a running wheel up until the time of mating), or post-weaning and gestational exercise (access to a running wheel until two days prior to giving birth). Additionally, age
- d and wheel freeness
- e (number of wheel revolutions following acceleration to a given velocity) were included in the model as covariates. Significance levels (P-values: bold indicates p < 0.05) for the effects of maternal (G1) exercise group (none, post-weaning only, post-weaning and gestational). The following covariates were also included in the analyses: Age, days since birth at the time of initial exposure to running wheel; Freeness, number of wheel revolutions following acceleration to a given velocity. Running wheel circumference was 1.1 m
