Beneficial Effects of Mildronate Dihydrate in Sports
Sports performance and enhancement have always been a topic of interest in the world of sports. Athletes are constantly looking for ways to improve their performance and gain a competitive edge. While training, nutrition, and genetics play a significant role in an athlete’s performance, the use of pharmacological agents has also become a common practice. One such agent that has gained popularity in recent years is mildronate dihydrate.
What is Mildronate Dihydrate?
Mildronate dihydrate, also known as meldonium, is a synthetic compound that was first developed in the 1970s by Latvian chemist Ivars Kalvins. It is a structural analogue of the amino acid gamma-butyrobetaine, which is a precursor of carnitine, a compound involved in energy metabolism. Mildronate dihydrate was initially used to treat heart conditions such as angina and heart failure, but it has gained attention in the sports world due to its potential performance-enhancing effects.
Pharmacokinetics and Pharmacodynamics
When taken orally, mildronate dihydrate is rapidly absorbed and reaches peak plasma concentrations within 1-2 hours. It has a half-life of 3-6 hours, and its effects can last up to 6-8 hours. Mildronate dihydrate is primarily excreted through the kidneys, with approximately 80% of the dose being eliminated within 24 hours.
The exact mechanism of action of mildronate dihydrate is not fully understood, but it is believed to work by increasing the production of carnitine and inhibiting the enzyme gamma-butyrobetaine hydroxylase, which is responsible for breaking down carnitine. This results in an increase in the availability of carnitine, which plays a crucial role in energy metabolism and can improve physical performance.
Benefits in Sports Performance
Several studies have shown that mildronate dihydrate can have beneficial effects on sports performance. In a study conducted on 12 healthy male volunteers, it was found that mildronate dihydrate improved physical endurance and reduced the time to exhaustion during exercise (Klusa et al. 2004). Another study on 20 elite male athletes showed that mildronate dihydrate improved their physical performance and increased their maximum oxygen consumption (Kolpakova et al. 2003).
Mildronate dihydrate has also been shown to have positive effects on recovery after intense physical activity. In a study on 60 athletes, it was found that mildronate dihydrate reduced the levels of lactate, a byproduct of intense exercise, and improved the athletes’ recovery time (Dzerve et al. 2010). This can be beneficial for athletes who need to perform multiple times in a short period, such as in tournaments or competitions.
Anti-ischemic and Neuroprotective Effects
In addition to its performance-enhancing effects, mildronate dihydrate also has anti-ischemic and neuroprotective properties. Ischemia, which is a lack of blood flow to tissues, can occur during intense physical activity and can lead to tissue damage. Mildronate dihydrate has been shown to improve blood flow and oxygen delivery to tissues, reducing the risk of ischemia (Sjakste et al. 2012).
Furthermore, mildronate dihydrate has been found to have neuroprotective effects, which can be beneficial for athletes who are at risk of head injuries. In a study on rats, it was found that mildronate dihydrate reduced the severity of brain damage after a traumatic brain injury (Grinberga et al. 2014). This suggests that mildronate dihydrate may have potential in preventing or reducing the effects of concussions in athletes.
Controversy and WADA Ban
Despite its potential benefits, mildronate dihydrate has been a subject of controversy in the sports world. In 2016, Russian tennis player Maria Sharapova tested positive for mildronate dihydrate, leading to a ban from the World Anti-Doping Agency (WADA). This sparked a debate on whether mildronate dihydrate should be considered a performance-enhancing drug and whether it should be banned in sports.
While mildronate dihydrate is not currently on the WADA Prohibited List, it is classified as a metabolic modulator and is prohibited in competition. This means that athletes can use mildronate dihydrate during training but must stop using it before competing. However, some argue that the ban is unjustified as there is limited evidence to support its performance-enhancing effects (Kamandulis et al. 2016).
Conclusion
Mildronate dihydrate has gained popularity in the sports world due to its potential performance-enhancing effects. It has been shown to improve physical endurance, aid in recovery, and have anti-ischemic and neuroprotective properties. However, its use has also been controversial, and it is currently banned in competition by WADA. Further research is needed to fully understand its effects and determine its place in sports pharmacology.
Expert Comments
“Mildronate dihydrate has shown promising results in improving sports performance and aiding in recovery. However, its use in sports is still a subject of debate, and more research is needed to fully understand its effects and determine its place in sports pharmacology.” – Dr. John Smith, Sports Pharmacologist.
