Supplementing Iron In Athletes: The How and Why

In past blog posts, I have briefly touched on iron supplementation. This practice is common among endurance athletes, especially triathletes, cyclists, and long distance runners. It is done because of the high risk of anemia and pre-anemia due to increased red blood cell turnover secondary to training. However, iron supplementation should be done with caution and under the watch of a professional. My general rule of thumb is to avoid iron supplementation until you see Read more…

Folate For Athletes: Don’t Ignore This Micronutrient!

Over the last few years, iron has become a supplement found on the shelves of most endurance athletes. Rightfully so, depleting iron levels leads to pre-anemia and anemia. For more information on iron, see my blog post on the topic (http://scienceoftriathlon.blogspot.com/2012/05/supplementing-iron-how-and-why.html). However, somehow the micronutrient folate has not received adquate attention. Endurance athletes have come to believe that if they are abnormally fatigued and feeling anemic, it is because of an iron deficiency. Yes, iron Read more…

Medications and Endurance Training: What You Should Know

Recently, a drug rep was in our clinic telling me how their pain medications would be good for the pains commonly experienced by athletes. I immediately thought about the importance of this topic and figured I better share some words on the blog about it. Not all primary care docs, nurse practitioners, and PA’s are familiar with the unique physiology of endurance athletes. It is important to take this into consideration when considering taking certain Read more…

Hey Endurance Athletes, Want Your Testosterone Back?

It’s no secret that endurance training can lead to reductions in testosterone. Theories behind the reduction of testosterone during endurance training previously revolved around the loss of body mass, increased cortisol levels, and changes in luteinizing hormone. However, there is some debate around this, and the mechanism is not 100% clear. Nonetheless, the reduction of testosterone can have a mildly negative impact on recovery from training and a big impact on your quality of life. Read more…

Antioxidants and Endurance Athletes

Antioxidants. From athletic performance and anti-aging to heart disease prevention and cancer treatment, antioxidants are touted as key components to fighting disease and optimizing wellness. Once considered the “fountain of youth”, these powerful, free radical fighting nutrients truly are amazing. They fight oxidative stress, a process that leads to cellular degradation and even cell death. Following their discovery, antioxidant supplements quickly found their way into endurance sports, and have been a mainstay supplement ever since. Read more…

Athlete Thermoregulation: Tips for Keeping Cool When It’s Hot

  Thermoregulation is the ability of an organism to maintain a body temperature within certain boundaries, even when the surrounding temperature is very different. Basically, this refers to your ability to stay warm in cool environments, and cool in hot environments. A physiological example of thermoregulation is sweating. The concept of thermoregulation is important to endurance athletes because it directly correlates to performance. The inability to control temperature swings results in a decrease in performance, Read more…

Maximizing Your Potential: Hemoglobin and Oxygen Delivery

Marginal gains. The term “marginal gains” is being heard more and more in the world of sports. The concept of marginal gains is simple. What are the little (marginal) things you can improve that cumulatively result in overall performance improvements? As a performance adviser to many of the world’s top endurance athletes, it is my job to identify where marginal gains can be made physiologically. One focus is oxygen availability, and a key player is Read more…

Why Eating Disorders In Endurance Athletes Are Especially Dangerous

It is time for those of us involved in endurance sports to bring attention to the problem of eating disorders in endurance athletes. I hope you will help address this problem by sharing this post with every runner, triathlete, and cyclist you know. Thank you. The topic of eating disorders in endurance athletes is too often neglected. The numbers are staggering. Studies show that up to 25% of female and 10% of male endurance athletes Read more…
