Influence of exercise-induced hamstrings fatigue on proprioceptive reweighting strategies and postural performance in bipedal stance in recreational athletes
Objective
An optimal proprioceptive reweighting strategy is necessary to maintain posture. A suboptimal strategy was associated with injury determinants and whether the strategy can be modified is unknown. Muscle fatigue can be used to investigate proprioceptive reweighting. The aims of this study were to evaluate the effects of local fatigue on proprioceptive reweighting strategies and postural stability as well as relationships between fatigue and these postural parameters.
Design
Fourteen recreational athletes were included. Relative proprioceptive weighting (RPW) was characterized according to the perturbation of the center of pressure (CoP) displacement generated by muscle vibration on a firm and foam surface. RPW evolution <95 % indicated that individuals were able to reweight proprioception from the ankle to lumbar signals according to the surface while evolution >105 % indicated that athletes maintained an ankle-steered strategy. Student's t-tests were used to compare RPW evolution, CoP velocity, and root mean square (RMS) before and after exercise-induced hamstring fatigue. Spearman's rank correlation coefficient was used to test the relationship between fatigue variables, RPW evolution, and stability variables.
Results
Hamstring fatigue induced an ankle-steered strategy characterized by an increase in RPW evolution when the surface was changed (P = 0.002) and an increase in CoP velocity (P = 0.045) and CoP RMS (P = 0.005) on firm surface. None of the correlation coefficients testing the relationship between the parameters proved to be significant.
Conclusion
Local fatigue leads to suboptimal proprioceptive reweighting strategies and impaired stability on firm surface. Results suggests that proprioceptive reweighting strategies are modifiable. Whether this predisposes participants to injury remains to be defined.
期刊介绍：
Human Movement Science provides a medium for publishing disciplinary and multidisciplinary studies on human movement. It brings together psychological, biomechanical and neurophysiological research on the control, organization and learning of human movement, including the perceptual support of movement. The overarching goal of the journal is to publish articles that help advance theoretical understanding of the control and organization of human movement, as well as changes therein as a function of development, learning and rehabilitation. The nature of the research reported may vary from fundamental theoretical or empirical studies to more applied studies in the fields of, for example, sport, dance and rehabilitation with the proviso that all studies have a distinct theoretical bearing. Also, reviews and meta-studies advancing the understanding of human movement are welcome.
These aims and scope imply that purely descriptive studies are not acceptable, while methodological articles are only acceptable if the methodology in question opens up new vistas in understanding the control and organization of human movement. The same holds for articles on exercise physiology, which in general are not supported, unless they speak to the control and organization of human movement. In general, it is required that the theoretical message of articles published in Human Movement Science is, to a certain extent, innovative and not dismissible as just "more of the same."
