This article deals with the problem of training students engaged in swimming groups. To maintain an optimal level of physical fitness there is the need for training in areas of high and moderate power, because it is more conducive to strengthening and maintaining cardiovascular, respiratory and other systems. To solve this problem, the authors defined a range of tasks and set a goal: to determine the swimming time limit to assess the performance and growth rate of training of students-swimmers of sports and preparatory groups in the moderate power zone. On the basis of the research to improve fitness in the zone of high power and improve the functional systems of the body, the authors recommend a maximum swimming time of 45 minutes as a control test and training task. This is justified by the fact that students engaged in swimming groups have different levels of training, so it is better not to set the length of the distance, but the time limit for swimming, both for the control test and for planning the load. A 30-minute limit training causes fatigue and traces of metabolic acidosis, even a day after the test. A 60-minute limit training causes changes in blood ABB indicators measured before work only with a significant decrease in efficiency as a consequence of the cumulative effect of several training sessions. The subsequent performance of the test 45 minutes limit swimming as a training task showed that 90% of students either increase the length of the distance or repeat their result, and further increase the length of the distance.
