Abstract
Background and Aims:
Present study was aimed to investigate the effect of two active recovery methods in and out water on cardiac stress indices in young female swimmers.
Methodology:
Sixteen young female swimmers were randomly divided into two active recovery groups of the inside and outside water. The swimming protocol and recoveries includes six bouts of 50 m sprint swimming with 120 s rest interval. The data was processed by using SPSS version 22 and Independent and dependent t-test.
Results:
Recovery inside the water led to insignificant increase in Double Product and systolic blood pressure (P=0.556and P=0.064 respectively) and significant increase in oxygen pulse (P=0.033). Also, insignificant and significant decrease in maximal heart rate and diastolic blood pressure were observed (P=0.188 and P=0.026 respectively). Outside water recovery led to insignificant and significant decrease in Double Product and maximal heart rate (P=0.980 and P=0.012 respectively). Also, insignificant increase in Oxygen Pulse and systolic and diastolic blood pressure (P=0.154, P=0.408 and P=0.109 respectively).were observed There was no significant difference between the effects of these two recovery methods on any of the indices (P≥0.05).
Conclusion:
According to our results, two active recovery methods, inside and outside water after high-intensity interval swimming training, somewhat moderates the cardiac stress indices. But there is no difference between the effects of these two recovery methods on cardiac stress indices.
