Gender and Age-Related Peculiarities of the H-Reflex Indices in Sportsmen

In a group of 44 healthy trained subjects (biathlon athletes), age- and sex-related peculiarities of the results of an H-reflex study were examined (EMG responses were recorded from the m. soleus). Tested subjects were divided into four groups, women and men, juniors (younger than 20 years), and adults (20–30 years). The measured indices in the groups of men and women demonstrated certain significant differences; these differences were greater in adults. Thresholds for generation of the H- and M-responses were higher in females as compared to those in males. Amplitudes of the maximum H- and M-responses in men (in both juniors and adults) significantly exceeded the analogous values in women. In adult sportsmen, amplitudes of the M-responses were higher, while ratios of the maximum H- and M-responses were smaller than those in juniors. Probable reasons of gender- and age-related peculiarities of the H-reflex indices are discussed.
