Interaction of Rate of Force Development and Duration of Rate in Isometric Force.
Siegel, Donald
A study attempted to determine whether force and duration parameters are programmed in an interactive or independent fashion prior to executing ballistic type isometric contractions of graded intensities. Four adult females each performed 360 trials of producing ballistic type forces representing 25, 40, 55, and 75 percent of their maximal voluntary isometric elbow flexor strength over five test days. During observation of the tests, duration of peak force and average rate at which force was produced were monitored and recorded. The data suggested that rate of force development and duration of force development varied inversely from trial to trial within different targeted force conditions. Furthermore, partial correlational analysis demonstrated that this relationship was independent of feedback from previous trials. It was concluded that some type of internal computation to adjust time and force parameters for one another takes place during the latency period occurring between when a subject decides to initiate a response and when the actual overt force is manifested.
