Evaluate the effects that different performance enhancing drugs (PEDs) may have on a sprinter's performance.

A sprinter's performance can be significantly affected by PEDs, both positively in terms of results and negatively in terms of health and ethics. One type of PED a sprinter might use is **anabolic steroids**. The positive effect is that they increase muscle mass and strength, allowing the sprinter to generate more power and therefore run faster. This can lead to improved times and winning medals. However, the negative effects are severe, including high blood pressure, heart disease, and mood swings ('roid rage'). Another PED could be **stimulants**. These increase alertness and reduce reaction time, which is beneficial for getting a fast start out of the blocks. They can also mask fatigue, allowing the sprinter to train harder. The negative health effects include addiction, high blood pressure, and increased risk of stroke. Overall, while PEDs can offer a clear short-term advantage in performance by increasing power and speed, their use is illegal, unethical, and carries extreme long-term health risks. The potential for improved performance is outweighed by the serious negative consequences for the athlete's health and the integrity of the sport.
