An Analysis of Perceived Exertion of a Graded Isometric Muscle Contraction of the Forearm Flexors Under Conditions of Magnitude Production and Magnitude Estimation
Description: This study analyzed an individual's ability to perceive levels of exertion of an isometric contraction. Two samples of college students were tested under magnitude production or magnitude estimation. A significant F was obtained for the magnitude production condition. An insignificant F was obtained for the magnitude estimation condition. This study concludes that subjects tested under magnitude production will perceive the 100 percent level with the least amount of error and that error will increase as the percentages descend from the 100 percent level. Subjects tested under magnitude estimation will be equally in error when perceiving percentages of a maximum contraction of the forearm flexors.
