All subjects performed maximal voluntary contractions (MVC) and an intermittent knee extension isometric submaximal voluntary fatigue task at 50% MVC until the fatigue criteria were met for pre-post testing. (wku.edu)
In order to determine which types of fatigue protocols are most likely to induce LFF, ten individuals participated in four different fatigue experiments which induced similar reductions in maximal force output as following: (1) 2-min intermittent high-frequency stimulation (40 Hz), (2) 4-min intermittent low-frequency stimulation (20 Hz), (3) sustained 100% maximal voluntary contraction (MVC), and (4) low-force voluntary contractions (20% MVC).
