When multiple electrical stimuli are applied to a muscle at a sufficiently high frequency, twitches merge into higher force contractions, a process referred to as summation. Summation is influenced by the time between successive stimuli (i.e. the inter-pulse interval, IPI), twitch force and twitch duration. shrimp mac n cheese near me

"WebThe twitch/tetanus ratio, F lu /F 0, depends on the velocity of contraction of the muscle fibers and on the viscoelastic properties of the muscle. The F,JF 0 of motor units is generally in the range, 0.1-0.4, the mean ratio for fast fibers being larger than that for slow fibers.. It may be noted that when motoneurons are firing asynchronously, as in voluntary contraction, the … " - Summation twitch
