  1. Individual group and time data expressed as means ± SD, while group effects are presented as means ± SEM. Data represents the isokinetic MVC knee extension and flexion performance each test session during the 10 day intervention. MANOVA analysis revealed overall Wilks' Lambda time (p<0.960) and group x time (p=0.748). Univariate ANOVA p-levels from MANOVA analysis are presented for each variable. Univariate ANOVA p-levels are listed first by the Greenhouse-Geisser (GG) analysis and then by the within-subjects contrasts (WSC) to demonstrate the potential shape of the time or group x time interaction with significance indicated by the following super/subscripts: * indicates p<0.05 p-level significance, § indicates p<0.10 p-level significance. LSD post hoc analysis is indicated by the following superscripts: ^ represents p<0.05 difference between groups, † represents p<0.05 difference from baseline value, Ψ represents p<0.05 difference from pre-lift, represents p<0.05 difference from 60-min post, # represents p<0.05 difference from 24-hr post. Ext = extension; Flex = flexion; IK = isokinetic; MVC = maximal voluntary contraction; G = group p-level; T = time p-level; G x T = interaction; q = quadratic p-level; L = linear p-level
