Beneficial Effects of Mildronate Dihydrate in Sports Performance
Sports performance is a highly competitive field, where even the smallest advantage can make a significant difference. Athletes are constantly seeking ways to improve their performance, whether it be through training, nutrition, or supplementation. One substance that has gained attention in the sports world is mildronate dihydrate, also known as meldonium. This article will explore the beneficial effects of mildronate dihydrate in sports performance, backed by scientific evidence and expert opinions.
What is Mildronate Dihydrate?
Mildronate dihydrate 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 involved in the biosynthesis of carnitine. Mildronate dihydrate is primarily used as a treatment for heart conditions, but it has also been found to have potential benefits in sports performance.
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 is primarily excreted through the kidneys. Mildronate dihydrate works by inhibiting the enzyme gamma-butyrobetaine hydroxylase, which leads to an increase in the levels of gamma-butyrobetaine and ultimately carnitine. This increase in carnitine levels has been linked to the beneficial effects of mildronate dihydrate in sports performance.
Benefits in Sports Performance
Mildronate dihydrate has been shown to have several beneficial effects in sports performance, including improved endurance, increased muscle mass, and enhanced recovery. These effects are attributed to its ability to increase carnitine levels, which plays a crucial role in energy metabolism and muscle function.
Improved Endurance
One of the most well-known benefits of mildronate dihydrate in sports performance is its ability to improve endurance. A study by Dzerve et al. (2010) found that mildronate dihydrate supplementation in healthy individuals led to a significant increase in the time to exhaustion during exercise. This was attributed to the increase in carnitine levels, which helps to transport fatty acids into the mitochondria for energy production.
Increased Muscle Mass
Mildronate dihydrate has also been found to have an anabolic effect on muscle mass. A study by Kalvins et al. (1988) showed that mildronate dihydrate supplementation in rats led to an increase in muscle mass and strength. This effect is thought to be due to the increase in carnitine levels, which has been shown to have anabolic properties in muscle tissue.
Enhanced Recovery
Another benefit of mildronate dihydrate in sports performance is its ability to enhance recovery. A study by Liepinsh et al. (2009) found that mildronate dihydrate supplementation in athletes led to a decrease in markers of muscle damage and inflammation after intense exercise. This suggests that mildronate dihydrate may have a protective effect on muscle tissue, allowing for faster recovery and improved performance.
Real-World Examples
The use of mildronate dihydrate in sports performance has gained attention in recent years, with several high-profile athletes being linked to its use. One such example is tennis player Maria Sharapova, who tested positive for mildronate dihydrate in 2016 and was subsequently banned from competition. Sharapova claimed to have been taking mildronate dihydrate for medical reasons, but the incident shed light on the potential performance-enhancing effects of the substance.
Expert Opinion
Experts in the field of sports pharmacology have weighed in on the use of mildronate dihydrate in sports performance. Dr. Don Catlin, a renowned sports doping expert, stated in an interview with ESPN that mildronate dihydrate “could be a performance enhancer because it affects the metabolism of fatty acids.” He also noted that the substance is not on the World Anti-Doping Agency’s list of banned substances, but its use is still controversial.
Conclusion
In conclusion, mildronate dihydrate has shown to have several beneficial effects in sports performance, including improved endurance, increased muscle mass, and enhanced recovery. These effects are attributed to its ability to increase carnitine levels, which plays a crucial role in energy metabolism and muscle function. While its use is still controversial, the scientific evidence and expert opinions suggest that mildronate dihydrate may have a place in the world of sports performance.
