  1. Individual group and time data expressed as means ± SD, while group effects are presented as means ± SEM. Data represents the response to muscle catabolism, mechanical damage, and physiological stress at each test session during the 10 day intervention. MANOVA analysis revealed overall Wilks' Lambda time (p<0.001) and group x time (p=0.504). 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. AST Aspartate aminotransferase, ALT Alanine aminotransferase, BUN blood urea nitrogen, CK Creatine kinase, G group p-level, T time p-level, G x T interaction, q quadratic p-level, L linear p-level
