Interplay between body stabilisation and quadriceps muscle activation capacity

The study aimed to distinguish the effect of stabilisation and muscle activation on quadriceps maximal isometric voluntary contraction (MVC) torque generation. Nine subjects performed a) an MVC with restrained leg and pelvis (Typical MVC), b) a Typical MVC with handgrip (Handgrip MVC), c) an MVC focusing on contracting the knee extensors only (Isolated knee extension MVC), and d) an MVC with unrestrained leg and pelvis (Unrestrained MVC). Torque and activation capacity between conditions were compared with repeated measures ANOVA and dependent t-tests.
