If you are going in for sports or like physical training, if you want to be in good shape during long period of time, you should know that:

• nicotine causes vasoconstriction, increasing the load on heart;
• smokers get short breath three times more often than nonsmokers do;
• smoking destroys lungs;
• smoking decreases oxygen level in blood. Oxygen is especially needed to muscles, when a person is going in for sports and when he or she needs to overcome serious loads;
• smokers run slowly. It is a problem for them to run a long distance over a short period of time.

Real sportsmen do not smoke!
