Decrease of force capabilities as an index of upper limb fatigue

摘要: The aim of the study was to assess upper limb fatigue on basis force change index (FCI), which expresses changes in developed force, and demonstrate that this differentiates muscle depending external load. performed ten young men 12 conditions Ten characterized repetitive work a two-period cycle, both or one periods were loaded, two continuous with constant participants tried maintain hand-grip at an imposed level during determined time standard posture. Changes values recorded exerted successive cycles approximated by regression function. In most cases there strong correlation between measurement data logarithmic curve. However, several lower load showed absence such correlation. 75% cases, statistically significant differences FCI calculated for individual That means not only quantitatively but also points resulting from results have shown (FCI) can be applied assessment discrimination more sophisticated model task than just simple rest model.
