Performance of a psychomotor skill following rest, exercise at the plasma epinephrine threshold and maximal intensity exercise

The purpose of this study was to examine the effect of exercising at the ep inephrine threshold and at Maximum Power Output on the performance of a ski ll that requires both decision-making and motor performance. Participants ( N=12) undertook an incremental test to exhaustion from which their epinephr ine threshold and Maximum Power Output were calculated. They were then exam ined on a soccer skill test following rest and exercise that was previously determined to elicit their epinephrine threshold and Maximum Power Output. The soccer test examined the participants' speed and accuracy of response. Speed of response was measured by voice reaction time and whole body react ion time. No significant effects of exercise were shown for any of the vari ables. The need for further research using more complex skill tests and the use of discontinuous exercise protocols, rather than continuous ones, is r ecommended.
