If you are planning to compete in national and international events, many stimulants are tested for in the blood and urine, and are deemed a severe doping offense if discovered. It can even cause you to suffer from heat exhaustion because it disrupts your body’s ability to cool itself. The common side effects of stimulant use include increase in blood pressure, heart attacks, chest pain, shortness of breath, stroke, palpitations, dizziness and anxiety. Phenylephrine is commonly found in over the counter cold medicine and is now used as a substitute for pseudoephedrine. It can be chemically modified to methamphetamine and thus have similar endurance, strength- and power-enhancing effects. Pseudoephedrine is a derivative of ephedrine and is commonly found in over-the-counter cold medicines. It works by enhancing the body’s production of noradrenaline (Adrenaline). Several studies have shown that cocaine has no beneficial effect on running times and reduces endurance performance.Įphedra (ma huang) is a popular herbal supplement that has been used to increase fat metabolism and overall sports performance. Contrary to popular belief, cocaine does not improve overall sport performance and has severe addiction potential. Similarly, cocaine is a strong central nervous system stimulant and is the most potent stimulant of natural origin. These stimulants have accounted for nearly 10% of adverse analytical finding by the World Anti-doping Agency (WADA) and are the most common reason for a positive test in many athletes participating in organized sports. A recent survey of nearly 21,00 students in grades 8-10 in the United States showed an increased use of amphetamines was found among males who participated in lacrosse and wrestling. Amphetamines are banned by the NCAA and Internatinal Olympic Commitee. However derivatives have been used as drugs of abuse, including ecstasy and MDMA. They also increase strength, muscular power, and endurance. Studies in cyclist have shown faster cycling time trials after caffeine ingestion.Īmphetamines are chemically synthesized, controlled substances that can be used to treat conditions such as narcolepsy and ADHD because they increase alertness and sharpen reflexes. It has been shown to increase reaction time and delay fatigue in sports like taekwondo. They include caffeine, cocaine, amphetamines, methamphetamines, ephedrine, pseudoephedrine, MDMA (ecstasy), and phenylephrine.Ĭaffeine is a performance enhancing stimulant found in numerous products we consume, such as soda, workout supplements, tea, chocolate, and coffee. These substances work on the central nervous system to increase alertness, concentration, metabolic rate, power, strength, and to decrease fatigue. Stimulants are used in sports to enhance performance.
