The purpose of this study was to examine the use of nonlinear analysis as a tool to evaluate postural sway patterns in athletes and physically active non-athletes. Balance is an integral part of many sports but seems to be task specific. Data collection occurred for 30 seconds during eyes open condition on Double Leg and Single Left and Right Leg trials. Analysis of the data using Transfer Entropy (TE) and Fractal Dimension (FD) yielded Ice Hockey and Football players having distinctly different postural dynamic control from each other and physically active non-players in only a couple conditions for TE and multiple conditions for FD. These balance measures support the idea of sports requiring different postural sway dynamics.
