What Color Are Your Fat Cells, White, Brown Or Beige?

No, this is not a decorating tip. Over the last decade researchers have developed a new understanding of our fat cells. Traditionally, fat cells were viewed as energy storage containers. Food that was not needed for metabolism or energy was converted into fat and then stored in white fat cells, principally located beneath the skin or in the abdominal cavity.

The Endorphin Myth

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.

Too Much Pain May Limit Performance Improvement

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

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

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.
