The difference between lactic acid accumulation in the blood, the time of the appearance of the anaerobic threshold and the number of times of breathing before, after and after the lactic effort contributed to the enduring the special strength of the arms

Abstract

The purpose of the research was to identify the difference in the accumulation of lactic acid in the blood, the time of the appearance of the anaerobic differential threshold, the number of times to breathe before and after the lactic effort in (200) meters freestyle, and to identify the level of muscular strength tolerance of the arms and the time of achievement of (200) meters of freestyle, and to identify the relationship and contribution of the difference in the level of lactic acid in the blood, the time of the appearance of the anaerobic differential threshold, and the number of times to breathe before and after the lactic effort with the endurance of the force and the time of achievement of (200) meters of freestyle, and the descriptive approach was adopted in the style of Relational studies, on a sample of (28) swimmers from Baghdad Governorate clubs participating in the sports season (2024-2025), the research sample was randomly selected to reach (24) swimmers with a percentage of (85.714%) of their original population, and after determining the measurements and tests under research, the descriptive study was conducted by applying it to the research sample and then processing the results by (SPSS) system The conclusions and applications are that the decrease in the difference in the accumulation of lactic acid in the blood before and after the lactic effort is related to and contributes to the increase in the level of the endurance of the special muscular strength and affects it directly, and it is associated with and contributes to the decrease in the achievement time of (200) meters of freestyle, and does not affect it, and that the increase in the difference in the level of the appearance of the anaerobic difference before and after the lactic effort is related to and contributes to the increase in the level of the endurance of the special muscular strength and is associated with and contributes to the decrease in the completion time of (200) meters of freestyle swimming and affects each of them positively. It is necessary to pay attention to the planning and application of training curricula that take into account the integration of adaptation in the positive effect of both the accumulation of lactic acid in the blood, the time of the appearance of the anaerobic threshold, and the number of breathing times, because of its positive role in increasing.
