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.
