Athletes use performance-enhancing drugs despite risks. Research focuses on the respiratory system for oxygen delivery, but many substances lack proven benefits, while asthma medications require careful regulation in athletes.

Area of Science:

  • Sports Medicine
  • Exercise Physiology
  • Pharmacology

Background:

  • Historically, various drugs have been used to enhance athletic performance, often with significant adverse effects.
  • The respiratory system is a key focus due to its role in oxygen (O2) consumption, delivery, and its connection to the cardiovascular system.
  • Enhancing maximal oxygen uptake (VO2 max) and prolonging its availability are critical for improving endurance and reducing fatigue.

Purpose of the Study:

  • To review methods and substances used for artificial enhancement of athletic performance.
  • To evaluate the efficacy and risks of ergogenic aids, particularly those affecting the respiratory system.
  • To discuss the implications of asthma prevalence and treatment in athletes.

Main Methods:

  • Literature review of ergogenic aids and their effects on athletic performance.

  • Analysis of substances affecting oxygen transport, including blood transfusions and erythropoietin.
  • Examination of stimulants, beta-adrenergic agonists, and their impact on respiratory and muscle function.

    • Main Results:

    • Oxygen-enhancing methods like transfusions and synthetic erythropoietin aim to increase tissue oxygen delivery but carry risks.
    • Stimulants and caffeine do not significantly support athletic performance.
    • Beta-adrenergic drugs, such as clenbuterol, illicitly affect muscle function, while others like salbutamol are therapeutic for asthma.

    Conclusions:

    • Many ergogenic aids lack proven efficacy and pose health risks.
    • The prevalence of asthma and bronchial hyperactivity in athletes necessitates clear diagnostic and therapeutic guidelines.
    • Therapeutic use of asthma medications in athletes must align with established medical guidelines, ensuring equitable treatment.
