Abstract
  • Mechanisms of motor control and function are interesting to those from the medical, athletic training and sports performance professions primarily during the development of conditioning and rehabilitation programs. The aim of this study was to assess spinal control mechanisms in two groups of explosively trained, female athletes from a NCAA Division 1- A institution. Comparisons of motor control variables were made between softball and volleyball players using Hoffmann reflex (H-reflex) measurements including: extrinsic presynaptic inhibition (EPI), intrinsic presynaptic inhibition (IPI) and the H: M ratio. One-way t-test results revealed no significant difference (p < .05) between the two groups in EPI (0.74±0.28 vs. 0.77±0.57), IPI (0.09±0.17 vs. 0.16±0.35) or the H: M ratio (0.57±0.17 vs. 0.56±0.26). Although the two groups participated in different sport-specific tasks over the course of a competitive season, both groups demonstrated similar reflex characteristics at rest. Thus, there were no differences between the two explosively-trained groups with respect to adaptations along the motor control, reflex pathway despite the two groups being from different sports.
