Muscular Force Generation in Microgravity

"MVC tested during three different tasks: (1) leg press, (2) plantarflexion and (3) grip strength.~parameters of muscle function that can be easily implemented in parabolic flight:~* Rate of force development~* Electromyographic activity~* Ultrasound measure: fascicle length and pennation angle of the gastrocnemius medialis muscle~* Superimposed twitch torque (M-waves at rest and V-waves in MVC conditions)~* Maximum voluntary activation capacity (%VA): %VA = (1-\[torque superimposed twitch/torque resting twitch\])\*100%."
