Study of the Electrocardiographic Profile in Judokas

Abstract

Introduction:Depending on the number of hours, load and type of physical exercise, the heart of an athlete undergoes changes throughout the sports practice, since it has an increase in its work to meet  the  metabolic  needs.  These  changes  may  result  in  a  condition  known  as  "athlete's  heart," where physiological cardiovascular changes are seen during exercise. Some of these changes can be observed at the electrocardiographic level, and can be differentiated between pathological and non-pathological  changes,  according  to  the  criteria  defined  for  athletes,  and  the  Seattle  criteria were used in this study. Objective: It was intended to analyze the electrocardiographic profile in judokas, to  observe  if  these  athletes  have  or  not  ECG  alterations,  and  if  these  alterations  are physiological  or  pathological.  It  was  also  verified  the  relationship  between  training  load  and electrocardiographic   alterations,   and   relationship   between   training   load   and   ECG   results. Methodology: Questionnaires and 12-lead electrocardiograms at rest were performed in a group of 20 judokas who practice judo for 1 year or more and age between 15 and 25 years. Main results: It was found that of the 20 judokas evaluated, all had sinus rhythm, 1 case with right axis deviation, 2  cases  with  sinus  bradycardia,  1  case  with  sinus  tachycardia,  1  case  of  left  ventricular hypertrophy,  and  the  remaining  variables  were  unchanged  in  the  ECG.  Conclusion:  Although  a small  sample  was  analyzed,  it  was  found  that  changes  in  ECGs  were  found,  but  they  are  not statistically significant, and also are not pathological for athletes, according to the Seattle criteria.
