Abstract : The research is designed to answer the following questions: Does prior loading in terms of grip-holding cause a decrement in manual dexterity; if a decrement does exist, how long does it last; and can decrement be predicted from the amount of endurance to which subjects are loaded. In answering these questions, ten male subjects were tested for manual dexterity using a Purdue Pegboard. Conclusions drawn from analyses are as follows: muscular loading in the form of grip-holding causes a decrement in manual dexterity; this decrement lasts for a period of ten seconds or less; and there is a relationship between the amount of endurance required by loading and the decrement caused by that loading.
