INFLUENCE OF ATHLETIC TRAINING ON VERTICAL STIFFNESS ATTENUATION
Keywords: fatigue, maximal, sub-maximal, female, unilateral, athletic populations
AbstractThe purpose of this study was to assess the stiffness differences between dancers, middle distance runners and recreational athletic populations under unfatigued and maximal effort tasks. A second aims was to evaluate the impact of athletic training in modulating stiffness under fatigued during maximal and sub-maximal tasks. A total of 18 participants between 18 and 30 years old were recruited for this study. All participants undertook pre- and post-fatigue vertical stiffness assessments through a discrete maximal and repetitive sub maximal counter movement jumps. Statistical tests revealed trends towards pre-existing unilateral vertical stiffness difference between maximal and sub-maximal populations. It is suggested that sub-maximal and maximal populations are able to attenuate stiffness under fatigued conditions due to training adaptations.
