The effect of the variables of arterial pressure and lactic acid on the endurance and accuracy of performance in the fight of the young boxers

Abstract

The study aimed to identify the differences between (S.AB), (D.AB), (PP), and lactic acid at rest before the start of the match and after physical exertion and the end of the three rounds, and to identify the differences between performance endurance and accuracy during each round of the three rounds. As for the research methodology, the researchers used the descriptive approach, and identified the research population from the boxers participating in the Basra youth championship held at Al-Mina Club with a total of seven clubs and 25 boxers. The researchers selected 8 boxers in the final rounds intentionally and the percentage was 32%.Based on the results obtained, the researchers concluded that measurements (S.AB), (D.AB), (PP) at rest are within normal limits, while after the three rounds there is a response and an increase in (S.AB), (PP) indicating a relative increase in functional efficiency, and a near increase to the normal level (D.AB) after physical exertion. Also, measuring lactate at rest before exertion is within normal limits of lactate concentration levels. After the three rounds, lactate accumulation increased to a level estimated to be five times its level at rest, with an inability to return to the normal state. The researchers recommended periodic examinations of physiological and chemical responses of boxers before and after physical exertion to determine their capabilities, specify the training method, and provide an indicator and guide for training load and intensity, emphasizing the use of lactate tolerance training for boxers to develop muscle endurance.
