The main purpose of this study is to compare the effect of two 10 and 15 minute-selected warm up programmes on subjects' blood lactate concentration
changes after an exhaustive exercise. 22 male undergraduate students in Physical Education Faculty of Tehran University were selected and then randomly assigned into two equal groups (n =11) often performing the Bruce maximal test.
One group performed a 10 minute-warm up programmes consisting of: 3 minutes calisthenics exericse, 3 minutes stretching exercise and 4 minutes running on the
treadmill with the speed of 6 km/h and 0 degree grade. The other group performed a 15 minute-warm up programmes in three stages: 4 minutes
calisthenics exercise, 4 minutes stretching exercise and 7 minutes running on the treadmill under similar conditions. Analyzing the data shows:
There is no significant difference between the two groups in blood lactate concentration changes (P=0.193) after warm up programmes. There is no significant difference between the two groups in blood lactate concentration changes after performing exhaustive exercise (P=0.106).
