Summary
It is well known that the training level
of a muscle belongs to the parameters that affect
the H-reflex response amplitude. The aim of this
study was to investigate the effects of training
type on H- and T-reflex response parameters. For
this purpose, 20 long-distance athletes (group I,
test group), 18 short-distance athletes (group
II, test group) and 20 non-trained subjects
(group III, control group) were involved in this
study in which the H- and T-reflex amplitude and
latency values were measured. The H-reflex
amplitude and latency values found in groups I,
II and III were 3.64±0.28 mV and 26.88±1.45 ms,
3.17±0.26 mV and 26.19±1.89 ms, and 6.07±0.34
mV and 26.77±1.32 ms, respectively. The T-reflex
amplitude and latency values of the groups I, II
and III were 3.30±0.18 mV and 32.01±1.02 ms,
3.11±0.20 mV and 31.47±1.16 ms, 4.24±0.21 mV
and 31.47±1.16 ms, respectively. There was no
statistically significant difference between the
groups with respect to latencies of H- and
T-reflexes (p>0.05). In both test groups, the
amplitudes of the H-reflex and T-reflex were
significantly smaller than the control group
(p<0.05). The results of this study suggest
that training of muscles affect the H- and
T-reflex response parameters.
