BIOVARIABILlTY: THE STARTING POINT FOR DEVELOPING RELIABLE MOTOR FEED-BACK PROCEDURES IN SPORTS

Abstract

Modem technologies allow multifactorial analyses of sports movement. Their output might be used as a reliable feed-back for sports motor applications, but individual variability must be assessed first, to gain more insight on treating data, interpreting results and presenting suggestions. Former studies evidenced important aspects of multijoint coordination and successfully interpreted the role of many kinematic/kinetic measures. Nevertheless they didn't examine biovariability extensively. In this work a common, Widely-studied field test (vertical jump) was chosen to evaluate intralintersubject variance. Results showed a considerable variability in many kinematic and kinetic parameters. Some suggestions on treating data are proposed. Some indications of possible applications are presented.
