The study of acceleration capacity decrease in repeated 30m sprints


Author(s): Riccardo Izzo, Valerio Morello Zenatello

Abstract: The purpose of this study (in collaboration with Prozone and K-Sport) was to highlight acceleration and deceleration (sudden drop in maximal velocity) capacity in repeated sprints by means of field test results. rnThe test consisted of 5x30m sprints, and the 20 selected athletes were monitored through the use of wearable 10Hz GPS devices, able to measure acceleration and deceleration parameters, which would otherwise not be detectable through photocells. The purpose of the study was to evaluate acceleration and deceleration capacity in repeated sprints (RSA) and high-intensity performance, with only 25 seconds rest between each sprint, by examining the speed and acceleration graphs as well as their peaks when signs of fatigue set in, through GPS devices. To verify repeatability the subjects were asked to perform the test several times, on a short term basis within a 24 hour period, and weekly on a long term basis. The test has proved to be a reliable means to measure capacity and performance as well as each subjects’ own performance ability improvement. GPS data have, for the first time, shown the variation of acceleration and speed peaks, and their trend during intermittent or high-intensity performance.
