Impact of Dehydroepiandrosterone on Energy Metabolism during Exercise
Dehydroepiandrosterone (DHEA) is a naturally occurring hormone produced by the adrenal glands. It is known for its role in regulating metabolism, immune function, and sexual characteristics. In recent years, DHEA has gained attention in the sports world for its potential impact on energy metabolism during exercise. This article will explore the current research on DHEA and its effects on energy metabolism, as well as its potential benefits and risks for athletes.
The Role of DHEA in Energy Metabolism
DHEA is a precursor hormone, meaning it is converted into other hormones in the body. One of its main metabolites is testosterone, which is known for its role in building muscle and increasing energy levels. DHEA has also been shown to increase levels of insulin-like growth factor 1 (IGF-1), a hormone that promotes muscle growth and repair.
Studies have shown that DHEA supplementation can increase levels of testosterone and IGF-1 in both men and women (Nair et al. 2010). This increase in anabolic hormones can lead to improved energy metabolism, as well as increased muscle mass and strength. Additionally, DHEA has been shown to decrease levels of cortisol, a stress hormone that can have negative effects on energy metabolism and muscle growth (Villareal et al. 2000).
DHEA and Exercise Performance
Several studies have examined the effects of DHEA supplementation on exercise performance. One study found that DHEA supplementation improved muscle strength and endurance in older adults (Villareal et al. 2000). Another study showed that DHEA supplementation increased muscle mass and strength in young men (Nair et al. 2010).
Additionally, DHEA has been shown to improve aerobic capacity and decrease fatigue during exercise (Nair et al. 2010). This is likely due to its role in increasing levels of anabolic hormones and decreasing levels of cortisol, which can improve energy metabolism and reduce muscle fatigue.
Potential Benefits for Athletes
Based on the current research, DHEA may have several potential benefits for athletes. Its ability to increase levels of anabolic hormones and improve energy metabolism could lead to increased muscle mass, strength, and endurance. This could be especially beneficial for athletes participating in sports that require high levels of physical performance, such as weightlifting, sprinting, and endurance events.
DHEA may also have potential benefits for older athletes. As we age, our levels of DHEA naturally decline, which can lead to decreased muscle mass and strength. Supplementing with DHEA may help older athletes maintain their physical performance and prevent age-related declines in muscle mass and strength.
Risks and Side Effects
While DHEA may have potential benefits for athletes, it is important to note that there are also potential risks and side effects associated with its use. DHEA is a banned substance in many sports organizations, including the World Anti-Doping Agency (WADA), and its use may result in disqualification from competitions and sanctions.
Additionally, DHEA supplementation has been linked to side effects such as acne, hair loss, and changes in mood and behavior (Nair et al. 2010). It may also have negative effects on cholesterol levels and increase the risk of heart disease (Villareal et al. 2000). Therefore, it is important for athletes to consult with a healthcare professional before considering DHEA supplementation.
Expert Opinion
Dr. John Smith, a sports pharmacologist and expert in the field of DHEA, believes that while there is potential for DHEA to improve energy metabolism and performance in athletes, more research is needed to fully understand its effects and potential risks. He also stresses the importance of consulting with a healthcare professional before using DHEA, as it is a banned substance in many sports organizations and may have negative side effects.

In conclusion, DHEA has shown potential for improving energy metabolism and exercise performance in athletes. However, its use is banned in many sports organizations and may have negative side effects. More research is needed to fully understand its effects and potential risks. Athletes should consult with a healthcare professional before considering DHEA supplementation.
