Such commercially available machines all aim at targeting and isolating the knee-flexor muscle group. Depending on mechanical design, they differ somewhat with regard to external torque offered and hence muscle use in the desired range of motion. Given the high rate of injury reported for the flexor-muscle group in athletes relying on high horizontal speed and power and the fact that leg-curl machines are frequently used both in prevention and rehabilitation of hamstring injuries, the scant information describing the basic kinematics of this exercise is rather surprising. A novel leg-curl device (YoYo Technology AB, Stockholm, Sweden) uses the inertia offered by rotating flywheels to provide resistance. Contrary to traditional weight-stack machines, this loading feature allows for exercise with eccentric overload, as shown elsewhere for configurations aimed at other muscle groups.With use of the flywheel leg curl, an 8-week training program improved maximal running speed and, perhaps even more important, reduced the incidence of hamstring strains in elite soccer players.<\/p>\n<div  class='avia-button-wrap avia-button-left  avia-builder-el-0  avia-builder-el-no-sibling ' ><a href='https:\/\/einercial.com\/wp-content\/uploads\/2019\/02\/2006_Tesch-Tous-Maldonado_Flywheel-leg-curl-machine-offering-eccentric-overload.pdf' class='avia-button  avia-color-theme-color   avia-icon_select-no avia-size-large avia-position-left ' target=\"_blank\" rel=\"noopener noreferrer\"><span class='avia_iconbox_title' >Seguir leyendo en PDF<\/span><\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>For the sole purpose of developing knee-flexor strength, power, and size, almost any weight room or training facility is equipped with a prone, face-down leg-curl weight-stack machine.
