title: [Modification of the Hoffmann reflex in function of athletic training (author's transl)].
abstract: The present study measures the values of the Hoffmann reflex and principally the relationship between the maximum reflex response and the maximum direct motor response (H max/M max) and their evolution. The subjects were athletes, performing aerobic and anaerobic type activities, divided into six groups (swimmers; soccer players; tennis players; sprinters; middle and long distance runners; and nonspecific athletes). The results show the average values of the H max/M max (53%) to be not different from those of nonathletes. When separated into aerobic and anaerobic groups, significant differences were found: the values are significantly inferior for subjects participating in anaerobic sports (37%) whereas we found an increase (from 55-75%) in the relationship for swimmers performing aerobic activities after 3 years of regular training. The results suggest, in accordance with previous authors, the possibility of a correlation between the modifications of the H max/M max and the type of activities (aerobic or anaerobic).
