Influence of the type of the nervous system on the velocity of punching by kickboxers

Abstract

The purpose of the article was to study the influence of the type of nervous system on the speed of hitting against the background of fatigue. The study was conducted on the basis of the Kharkiv State Academy of Physical Culture. A total of 33 kickboxing athletes took part in the study, 15 of whom have the first sports category, 17 have second. The type of the nervous system was determined by two tests - the Schulte tables and the tapping test. Punching speed testing was determined by performing 20 consecutive punches without rest. According to the efficiency of working on the Schulte tables, control group I has a tendency to increase the result from table to table, which characterizes the subjects as having a weak nervous system. The graph of control group II reaches a peak on the second table, and then gradually decreases. Thus, control group II can be characterized as athletes with a strong type of nervous system.
 The obtained data on the type of nervous system in the groups of subjects are confirmed by means of a tapping test (. Thus, KGI has a downward graph starting with 5.3 hand movements per second during the first five seconds with a gradual decrease until the thirtieth second. KGII has a curved graph of the results of the tapping test with a peak at 10-15 seconds. During the first five seconds, the group average was 4.7 hand movements per second, rising to 5.5 and holding at that level, then decreasing to 4.4 movements per second. According to the results of the study, it was found that athletes with a strong type of nervous system can maintain the speed of hitting for a longer time.
