The purpose of this research are to study the effect of active recovery including: 1- swimming with rate of 1:3 (work to rest), 2- cycle swimming 3- breathing, and also inactive recovery (sitting on the side of pool), on time record of 100, meter breaststroke swimming and on return of heart rate (HR) at the end of the 100 meter swimming in elite swimmers. The subjects were 19 male, 13 - 14 years swimmers of Tehran, who were under supervision of international coaches, and technical committee of Iran Swimming Federation. They took part in a training program of 6 days per week, 2 hours per session, which covered four types of swimming. Method of this research was semiexperimenta1; and for the assessment of factors, at the begining all Swimmers individually swam 100 meter and time was recorded (pretest). Then, they were experienced different types of recovery for 3 minutes. After recovery, the times, each time consists of three stages (one pretest and two post test for each type of recovery) and the effect of any recovery stage according to the time of records was
matched to each other. Also, At the first and last 6 second period of recovery time, HR was recorded and the effect of and recovery stage on return of HR were compared. The repeated measure test & contrasts test were used to analyze the data.
Results:
1- No significant difference was found between the first timerecords of 100 meter swimming in different sets of experiment.
2- The effect of different types of recovery on the second timerecords of 100 meter swimming was significantly different, but it was not significant for the third time-records of 100
meter.
3- No significantly different, was found between the HR of swimmers during the first 3 minutes of different types of recovery.
4- The return of HR during the second 3-minute time period of different types of recovery, was significantly different.
Concsusion: Concerning the conditions of this study, there was no significant difference between the effects of different types of recovery on swimming performance of subjects. However, the best type of active recovery was the swimming with rate of (1:3). Finally, the changes of HR following four types of recovery does not seem to be a reliable index for prediction of swimming performance.
