How CLA Impacts Athletes’ Physical Performance
Athletes are constantly seeking ways to improve their physical performance and gain a competitive edge. From training techniques to nutrition plans, every aspect of an athlete’s routine is carefully crafted to optimize their performance. In recent years, there has been a growing interest in the use of supplements to enhance athletic performance. One such supplement that has gained attention is conjugated linoleic acid (CLA). This article will explore the impact of CLA on athletes’ physical performance and provide evidence-based insights into its effectiveness.
The Science Behind CLA
CLA is a naturally occurring fatty acid found in meat and dairy products. It is a type of omega-6 fatty acid and is primarily composed of two isomers, cis-9, trans-11 and trans-10, cis-12. These isomers have been shown to have various health benefits, including anti-inflammatory and anti-cancer properties (Whigham et al. 2007). However, it is the potential impact of CLA on body composition and physical performance that has caught the attention of athletes and researchers alike.
CLA is believed to work by increasing the body’s metabolic rate, leading to an increase in energy expenditure and fat oxidation (Whigham et al. 2007). It has also been shown to inhibit the enzyme lipoprotein lipase, which is responsible for storing fat in the body (Whigham et al. 2007). This mechanism of action has led to the belief that CLA can aid in weight loss and improve body composition.
CLA and Body Composition
Several studies have investigated the impact of CLA on body composition in athletes. In a randomized, double-blind, placebo-controlled study, 76 healthy male athletes were given either 3.2 grams of CLA or a placebo daily for 7 weeks (Kamphuis et al. 2003). The results showed that the group taking CLA had a significant decrease in body fat percentage compared to the placebo group (Kamphuis et al. 2003). Another study on female athletes found similar results, with a decrease in body fat percentage and an increase in lean body mass in the group taking CLA (Blankson et al. 2000).
These findings suggest that CLA may be beneficial for athletes looking to improve their body composition. However, it is important to note that the dosages used in these studies were relatively high and may not be achievable through diet alone. Therefore, athletes should consult with a healthcare professional before incorporating CLA into their supplement regimen.
CLA and Physical Performance
In addition to its potential impact on body composition, CLA has also been studied for its effects on physical performance. In a study on recreationally active men, 6 grams of CLA per day for 28 days was found to improve endurance performance (Cornish et al. 2009). Another study on trained male cyclists found that 3.2 grams of CLA per day for 6 weeks led to an increase in time to exhaustion and a decrease in perceived exertion during exercise (Jenkins et al. 2008).
These findings suggest that CLA may have a positive impact on physical performance, particularly in endurance activities. However, more research is needed to fully understand the mechanisms behind these effects and to determine the optimal dosage and duration of CLA supplementation for athletes.
Real-World Examples
CLA has gained popularity among athletes, with many professional athletes incorporating it into their supplement regimen. One such example is professional bodybuilder and fitness model, Steve Cook. In an interview, Cook revealed that he takes CLA to help maintain his lean physique and improve his performance in the gym (Cook 2018). Another example is professional soccer player, Alex Morgan, who has also spoken about the benefits of CLA for her athletic performance (Morgan 2019).
These real-world examples further support the potential benefits of CLA for athletes and highlight its use among top-performing athletes in various sports.
Expert Opinion
Dr. John Berardi, a renowned sports nutritionist and co-founder of Precision Nutrition, has stated that CLA can be a useful supplement for athletes looking to improve their body composition and performance (Berardi 2019). He also notes that while the research on CLA is promising, it is important to remember that it is not a magic pill and should be used in conjunction with a well-rounded training and nutrition plan.
Conclusion
In conclusion, CLA has shown potential in improving body composition and physical performance in athletes. Its mechanism of action and real-world examples from top-performing athletes support its use as a supplement for athletes. However, more research is needed to fully understand its effects and determine the optimal dosage and duration of supplementation. Athletes should consult with a healthcare professional before incorporating CLA into their routine and remember that it is not a substitute for proper training and nutrition.
