What is The Twitch Interpolation Technique for the Estimation of True Quadricepsmuscle Strength about?

The aim of this study was to examine the reliability of the twitchinterpolation technique when used to estimate the true isometric knee extensor muscle strength.This included an examination of whether submaximal activation causes any bias in the estimationof the true muscle strength and an examination of the precision of the method. Twenty healthysubjects completed three contraction series, in which the sub‐jects were told to perform as if theirvoluntary strength was 60%, 80% or 100% of that determined by a maximalvoluntary contraction (MVC). Electrical muscle stimulations were given at each of five differentcontraction levels in each series. At torque levels above 25% of MVC the relationshipbetween torque and twitch size could be approximated to be linear. The true muscle strength(TMS) could therefore be estimated using linear regression of the twitch–torquerelationship to the torque point of no twitch in each of the three series, termed TMS~60~, TMS~80~ and TMS~100~. The TMS~80~ was slightly lower (__P__<0·01), median 94% (IQ range 87–101%) of the TMS~100~. The TMS~60~ was median 99% (IQ range 83–125%)(NS) of TMS~100~, but a few severe outliers were ob‐served. In conclusion, we f
