Eccentric Exercise: What I’ve Been Missing

by Hilary Froman, PharmD 

My entire life, I’ve ignored the second half of my workout… 

When someone first hears the term eccentric exercise, they might imagine a quirky, “eccentric” aunt participating in one of those fad exercises -doing aerobics in high heels, or running around on Kangoo Jumps (springs for your feet). Eccentric exercise shares no relation to these exercise fads, but don’t ignore it – it could be your answer to many exercise problems. 

What is eccentric exercise? 

Muscle contractions occur in three ways: 

isometric, concentric, and eccentric. During 

an isometric muscle contraction, the 

muscle contracts without changing length. 

A concentric muscle contraction makes a

Eccentric exercise/training focuses on the eccentric portion of a muscle contraction – for example, taking five seconds to lower your hand during a bicep curl instead of just dropping it-not as wild as doing aerobics in heels, but much more useful.

Bellinger, Qi Gong teacher and PTA at ALTA, deftly led a Qi Gong practice. Kristine first talked about stress and its effects on health during her talk – Slow Down and Ground. We then had a wonderful 30 minute Qi Gong lesson. I left feeling relaxed and rejuvenated.

Keeping Young Athletes Healthy 

Over the last three decades, the intensity of children’s sports has changed. In the Front Range, whole catalogs are devoted to sports camps. Club sports are proliferating and, in a community where physical activity is highly valued, competition to excel is huge. Parents are hiring personal coaches and trainers to help their children in the off-season. As a result, children are training year round for their particular sport. 

Early specialization combined with year-round training has led to an increase in overuse injuries in children. 30-50% of all pediatric sports injuries are from overuse, and overuse injuries sideline children longer than acute injuries according to the Journal of Sports Medicine and Fitness. 

What is an overuse injury? 

Repeating the same motions over and over causes a specific tissue, such as a tendon or bone, to fatigue. With rest, the tissue recovers, adapts to the demand, and is able to withstand more load without injury. Without rest, inflamed structures release enzymes that damage local tissue and can cause lasting degenerative changes.
