Metabolic stress of muscle during interval exercise. Top) Mean ± SD, and post-hoc p-values, bottom) and p-values of the main effects of interval ‘training’, the contraction ‘group’, and muscle, on the average and total oxygen deficit and hemoglobin concentration accruing in m. vastus lateralis and m. gastrocnemius combined during interval exercise before and after training (i.e., week 1–2 vs. week 7–8). Repeated-measures ANOVA with multivariate test correction for Roy’s Largest Root. Underlined p-values were deemed significant.
