Lungs are measured using a spirometer, aerobic capacity using the arm kerring, and anaerobic capacity using wingate. On the next day, all the subjects participated in a canoeing race, and after the race, the measurement was done again. Finally, descriptive statistics, Shapiro-Wilk tests, analysis of variance with repeated measures and Tukey's follow-up are used for the statistical analysis of the data.
