Abstract

In swimming competitions, races are held several times a day, including qualifying rounds and final races. To achieve high performance throughout, it is necessary for competitors to cool down immediately after each race. For this reason, they tend to use sub-pools. However, the game venues for junior swimmers in Japan are often not equipped with sub-pools. Accordingly, the purpose of this study was to assess the cooling-down methods that junior swimmers can adopt without using a sub-pool. The participants of the study were fifteen male junior swimmers （mean age 15.1 ± 1.8 years; height 1.67 ± 0.6 m; body mass 57.0 ± 5.0 kg）. After finishing the 200 m full-strength swimming （Trial 1）, they also completed three randomly assigned cooling-down tasks （70% OBLA, walking, and passive）, and conducted 200 m fullstrength session again（ Trial 2）. As the result of the experiments, it was revealed the rate of lactic acid removal rates after cooling down was significantly higher in the order of 70% OBLA, walking, and passive trial, while there was no significant difference between the results of Trial 1 and Trial 2. It was suggested, therefore, that each method had little effect on the subsequent swimming performance.
