A major topic in sports medicine is understanding how drugs can effect athletic performance and how to avoid unwanted complications. Many drugs have side effects that might be exaggerated by strenuous exercise.
Prescription drugs are controlled because of their side effects. The topic can be divided into drugs that affect the body versus drugs that affect the mind.
Mood altering drugs and pain killers, like NSAIDS, can affect performance. A person who is advised to avoid driving or operating machinery should also be careful around exercise equipment and free weights. These count as heavy machinery, so any drugs that affect coordination should make a person rethink some of the exercises that they do.
A power step machine is safer than running on a treadmill, and weight lifting machines are safer than free weights.
Drugs that affect blood pressure might disqualify a person from intense cardio. Some people need medicine that raises their blood pressure, but cardio further increases blood pressure. Someone suffering from high blood pressure as a disease is also at risk. It is better to ask a doctor for a routine and stick to walking until then.
