Fig. 7From: Effects of beta-hydroxy-beta-methylbutyrate (HMB) on the expression of ubiquitin ligases, protein synthesis pathways and contractile function in extensor digitorum longus (EDL) of fed and fasting ratsData of maximum skeletal muscle strength production in EDL. Muscle twitch force was determined at 1 Hz and tetanic force was at 100 Hz electrical stimulation frequency. a Muscle twitch force; b muscle tetanic force; c specific muscle twitch force normalized per CSA (fed vs. fasting, p = 0.07); d muscle tetanic force normalized per CSA. Results are expressed as mean ± SEM (n = 6 animals/group); in white Fed:Control and Fasting:Control and in black Fed:HMB and Fasting:HMB Back to article page
