Introduction: Swimming is a sport that requires mastery of muscle groups, breathing, and cardiopulmonary strengthening, being a complete physical activity. To improve the competitive level of its athletes, making possible better results in competitions is a frequent challenge that demands training analysis and frequent adaptations. Objective: Study the effects of current physical training on the competitive performance of athletes. Methods: Twenty-four volunteer swimmers were selected and equally distributed in two groups. The experimental group performed swimming-specific physical training according to the established training plan, and the control group performed general physical training based mainly on running. There was no difference in the duration or intensity of training between the groups. The experimental period was 8 weeks, three times a week. Results: The experimental group was superior to the control group in terms of optimizing physical function, optimizing special fitness, and improving athletic levels. Conclusion: Special physical training for athletes can improve swimmers’ physical function more efficiently, improve their competitiveness and sports efficiency, and reduce sports injuries.
