I am reffering to raising your temprature and heart rate before exercising, then walking to prevent blood pooling after exercise.
Let me go through why really quick.
Warm Up - this prepares the body for exercise, the increased blood flow to the heart and muscles does not begin immediatly. In fact electrocardiograms have shown abnormal heart arrhythmia's during exercise without a warm up.
Cool Down - during exercise the heart pumps large amounts of blood to the working muscles. The muscles squeeze the veins which forces blood back to the heart, valves in the heart prevent the blood from flowing backwards. If exercise is stopped suddenly the blood is left in the area of the working muscle, this causes blood pooling which causes the heart to have less blood to pump, causing
blood pressure to drop and possibly dizziness or loss of conciousness.
Now after all of that let me be the first one to check the NO box for both of these. I prescribe it but it is just hard to get motivated to warm up, or cool down (that's the walk to and from the parking lot.) When I get to the gym I am almost bouncing up and down with excitment to go start moving some iron. I do start off with a warm up set but that is to
prevent injury and really doesn't get my heart pumping or my temprature up, the thought of the weight I am about to push thinking that it can beat me does that.
Even though I know I should I will be honest and say that I don't.
