Changes in blood pressure, heart rate and perception of fatigue in Recovery to primary active state in water with three different temperatures, after an exhausting activity

Abstract:The present study aims to compare the effects of different temperatures of water on systolic and diastolic blood pressures, heart rate and perception of fatigue when returning to the primary active state, after a 200-meter front crawl swimming. Thus, 13 female students with a mean age of 21.84 ± 1.86 years, height of 162 ± 3.85 cm and weight of 57.46 ± 8.44 kg were voluntarily chosen and swam 200 meters front crawl in three different days within a week and then they attended in one recovery method for 5 minutes including, walking slowly in cold water, (20?), walking slowly in warm water (39?) and walking slowly in mild water (28?). In order to evaluate data, repeated measurements and Bonferroni test were used. Results showed that the recovery in cold and mild water shows the greatest reduction in heart rate (p = 0/001) compared to warm water and there is also a significant difference in the recovery in mild and warm water (p=0/03). Systolic blood pressure in warm water was the lowest compared to other two methods after recovery to the active state (p=0/009) and diastolic blood pressure had the maximum reduction in warm water (p=0/017). Recovery to the primary active state in cold water significantly increased perception of fatigue in comparison to other methods (p=0/009).
