Concussion history and balance performance in adolescent rugby union players
Matthews, M., Johnston, W., Bleakley, C. M., Davies, R. J., Rankin, A. T., Webb, M., Caulfield, B. C., Archbold, H. A. P.Published in The American Journal of Sports Medicine (2021)“…Dependent variables were normalized reach distance and the sample entropy (SEn) of the 3 axes (x, y, and z). Results: Of the 195 participants, 100 reported a history of concussion. …”

The role of variability in the control of the basketball dribble under different perceptual setups
Robalo, R., Diniz, A., Fernandes, O., Passos, P.Published in European Journal of Sport Science (2021)“…A variability analysis (correlation dimension, approximate entropy and Lyapunov exponent) was used to evaluate how an increased variability or stability, in a specific joint movement, contributes to a better adaptive behaviour when facing perceptual impairment. …”

Perceptual-cognitive expertise when refereeing the scrum in rugby union
Moore, L. J., Harris, D. J., Sharpe, B. T., Vine, S. J., Wilson, M. R.Published in Journal of Sports Sciences (2019)“…., other) locations, and exhibited lower entropy than the players. While search rate failed to predict decision-making accuracy, the time spent fixating central-, outer-, and non-pack locations, as well as entropy, were significant predictors. …”

Effect of defensive pressure on movement behaviour during an under-18 basketball game
Leite, N. M., Leser, R., Gonçalves, B., Calleja-Gonzalez, J., Baca, A., Sampaio, J.Published in International Journal of Sports Medicine (2014)“…The positional data were captured by the Ubisense Real Time Location System and analysed with non-linear signal processing methods (approximate entropy) and repeated measures ANOVA. There were differences in the regularity values between F¼ and FULL in distance to the basket and to the opponents` basket. …”

Morpho-textural changes of the patellar ligament in professional volleyball players: 6 months longitudinal study
de-Groot-Ferrando, A., Rios-Diaz, J., Martinez-Paya, J. J., del-Baño-Aledo, M. E.Published in British Journal of Sports Medicine (2013)“…The morphometric parameters were: echogenicity, echogenicity variation, width, thickness and circularity; and GLCM textural features: contrast and entropy. Image analysis was performed with ImageJ software v1.44. …”

Competitiveness and uncertainty in the NBA and ACB professional basketball leagues
de Saa Guerra, Y., Martin Gonzalez, J. M., Garcia-Manso, J. M.Published in World Congress of Performance Analysis of Sport IX (2012)“…We studied 18 NBA and 14 ACB regular seasons. Both leagues´ entropy levels are high (NBA mean 0.984; ACB mean 0.979), which indicates high competitiveness, but the entropy of the ACB (from 0.972 to 0.987) shows more seasonal variability than the NBA (from 0.985 to 0.990). …”

Herzfrequenzvariabilität (HRV) und subjektives Belastungsempfinden (PE) während spielsportspezifischer Ausdauerbelastung
Gerhard, J., Lott, C., Hoos, O.Published in Herzfrequenzvariabilität: Gesundheitsförderung - Trainingssteuerung - Biofeedback. Internationales Symposium am 29. und 30. Oktober. (2011)“…Beneath traditional HRV parameters, fractal correlation properties and predictability of RR-intervals were analysed using short-term scaling exponent a1 of DFA and sample entropy (SampEn). A repeated measure ANOVA was used to reveal significant changes in HRV-parameters with increasing PE. …”
