چکیده مقاله:

The purpose of this study was to determine the relationship between changes of some of the cardiorespiratory factors during submaximal activity with slow component of Vo2 after static and dynamic stretching in 16 active women from physical education college ( Mean ± SD : age, 23.87± 1.62 yr ; weight, 57.20 ± 7.84 kg ; height, 163.46 ± 6.23 cm; body fat % ,23.96 ± 2.70 and Vo2max, 42.15 ± 3.41 ml.kg-1.min- 1). After measurement of Vo2max and LT , the subjects performed two protocols of stretching (static and dynamic) and one protocol without stretching before submaximal activity (treadmill running at 70% Vo2max) in three separate sessions. Respiratory gas exchange and HR was measured by gas analyzer and polar and time constants (τ1- τ2 - τ3) were calculated from O2 kinetics graph. Results revealed a positive correlation between slow component of Vo2 with changes of VE (0.76), Fb (0.48), Tv (0.67), HR (0.41), τ1 (0.49) ,τ 2 (0.52) , τ 3 (0.46) and steady state oxygen uptake increased significantly after static stretching (P=0.031). Therefore, results of this study showed that some of changes in slow component of Vo2 after static and dynamic stretching related to metabolic and cardiorespiratory factors.
