Aim. The purpose of the study was to examine whether detraining for two months would have an effect on pulmonary function as well as on the performance in adolescent female swimmers.
Methods. Thirty-eight (38) female swimmers (aged 12-14) participated in this study and were divided into three groups on the basis of a special questionnaire they filled in. In the course of the detraining, the swimmers of group A (n=15) engaged in various athletic activities of moderate intensity 5-6 times a week. Group B (n=13) engaged in the same athletic activities of moderate intensity 2-3 times a week. The swimmers of group C (n=10) did not engage in any athletic activity. All the swimmers were submitted to spirometer control with a Pony Graphic Spirometer both at the beginning and the end of the detraining period. They were tested for VC, FVC, FEV1, FEV1/FVC, PEF and FEF 25-75. In addition, all the swimmers participated in a swimming test in the 50 m and 200 m front-crawl at the beginning and the end of the detraining period.
Results. According to the results, the rates of respiratory parameters showed a decrease. The decrease observed in the respiratory parameters, especially for group C, led to a small decline in swimming performance for the 50 m and a greater decline for the 200 m front crawl.
Conclusion. In conclusion, the decreases in the rates of respiratory parameters, during the two-month detraining period, undoubtedly had a negative effect on the swimmers’ performance. This negative effect is evidently greater in swimming events which demand a higher percentage of participation on the part of the aerobic energy system.
