A two-way (eccentric versus concentric training) repeated measures (pre-training versus post-training) ANOVA, with a 5% significance level, was used to compare: (a) the vastus lateralis muscle architecture (fascicle length, pennation angle, and muscle thickness); (b) the patelar tendon morphological properties (tendon length and anatomical cross-sectional area); (c) the torque angle relation; and (d) the torque-velocity relation between the concentric and eccentric groups.
Mean PK activity in dog heart is ~6 times and in vastus lateralis muscle ~26 times higher compared to mean CS activity [52]; human vastuslateralis muscle seems to be somewhat less glycolytic; ratio of mean activities of the abovementioned enzymes is ~17 [53].
The capacity of classic markers for mitochondrial density, ie, the capacity of citrate synthase (CS) and succinate dehydrogenase (SDH), as well the capacity of cytochrome c oxidase (COX) and beta-hydroxyacyl-CoA dehydrogenase (HAD), was determined in homogenized muscle biopsy samples obtained from the vastus lateralis muscle of nonexercising healthy young (age 20 [+ or -] 2 yr) subjects (31 women, 7 men).

Knee extensor (7.5 x 10 cm): One electrode was placed on the skin 2 to 3 cm above the superior aspect of the patella over the vastus medialis muscle, and the other electrode was placed lateral to and 30 cm above the patella over the vastus lateralis muscle.
