The Endorphin Myth
The "Runner's High" was first described in the 1970's. Runners, after covering lengthy distances, described their mood as euphoric. This description initiated a great deal of research to determine if the "runner's high" had a basis in physiology.  In the 80's a number of studies were published linking the "runner's high" to the release of endorphins, natural opioids produced by the body. Research suggested that endorphins released during extended endurance exercise acted similar to morphine producing feelings of euphoria. In other words, endorphin release created the "runner's high". Case closed.

Can A Tattoo Impair Endurance Performance?

Even suggesting a tattoo can negatively impact endurance performance sounds like heresy. Tattoos have become part of our life (or more accurately our bodies). Approximately 30% of Americans have at least one tattoo, which is a significant increase over the last seven years. Against this backdrop is a recent report that suggests tattoos could impact endurance performance.

Too Much Pain May Limit Performance Improvement

The association with pain and improved performance evolved from research in many laboratories showing that when muscles are stretched, they activate specific metabolic pathways responsible for building new and stronger muscle protein. In fact, after intense exercise, muscle remodeling, which ultimately leads to improved performance, takes place. Athletes have interpreted this research as "more is better". The more pain, the greater the improvement in performance through an increase in the size and strength of muscle cells.

COVID-19 Vaccine & Endurance Athletes
Endurance training confers a number of benefits, such as a stronger immune response, that could potentially decrease the severity of COVID-19. Sometime in 2021, probably in the second or third quarter, a COVID-19 vaccine should be available. A logical question for serious endurance athletes is whether they should take the vaccine. Will their training be negatively impacted? How will their body respond?

Caffeine & Sports Performance

Caffeine & Sports Performance

For many athletes, especially those who exercise in the morning, workout begins with a cup of coffee. For athletes and non-athletes alike, coffee jump starts their day. This caffeinated boost wakes us up and makes us more alert. With the proliferation of coffee shops on every corner and caffeinated products sold in grocery and convenience stores, we have become a caffeinated nation…

Can Exercise Reduce The Severity Of COVID-19?
Regular exercise strengthens immune health and good immune health may decrease the severity of symptoms associated with COVID-19. The most dangerous symptom of COVID-19, acute respiratory distress, is the primary cause of death. A recent article authored by a well-known scientist from University of Virginia, suggests that...
