Forty-six varsity ice hockey players participated during the 2014-15 season. All underwent baseline measurements and were tested ever 4 weeks throughout the season, plus one post-season session. Dependent linear (mean power frequency, mean velocity, and total excursion) and nonlinear (approximate entropy) measures were used to interpret force plate data. Linear and nonlinear measures both showed significant main effects of time. Monthly testing throughout the season demonstrated decreases in mean values for all measures with respect to baseline.
