Review Questions

• How do stimulants affect physiological functions during physical activity?
  • Stimulants enhance physiological functions by increasing alertness, energy levels, and endurance. They work by stimulating the central nervous system, which can lead to heightened focus and reduced perception of effort during exercise. This allows athletes to push harder and perform better for longer periods. However, it’s important to recognize that while they may provide short-term benefits, they also carry risks such as increased heart rate and potential for addiction.
• Discuss the ethical implications of using stimulants in competitive sports.
  • The use of stimulants in competitive sports raises significant ethical concerns surrounding fairness and integrity. Athletes who use these substances may gain an unfair advantage over their competitors who adhere to regulations against such practices. Moreover, the pressure to perform at higher levels can lead athletes to misuse stimulants despite the health risks involved. Sports organizations strive to ensure fair play by implementing anti-doping measures; however, this creates a complex landscape regarding what is acceptable and what crosses the line into cheating.
• Evaluate the impact of stimulant use on long-term athletic performance versus potential health risks.
  • While stimulants may offer immediate enhancements in athletic performance by boosting energy and reducing fatigue, the long-term impact raises serious concerns. Regular use can lead to tolerance, dependence, and potential health issues such as cardiovascular problems or mental health disorders. Athletes must weigh the short-term benefits against these risks when considering stimulant use. The debate continues on how best to balance performance enhancement with athlete safety and fair competition in sports.
