Your Aerobic Engine

From a science perspective marathon running is a 99% aerobic activity. (Source: “Training Distance Runners” by Dave Martin & Peter Coe). The half marathon is 98% and the 10k 97%.

Therefore, building your aerobic engine is critical to your healthy, successful completion of these events. Without this capacity, regardless of your pace, success is not possible. In the Lydiard Training Method this work is accomplished during phase 1, Aerobic Base Building.

At the heart of your aerobic engine are the Mitochondria which are found in your muscle cells.

Mitochrondria are critical as this is where ATP-Adenosine Tri Phosphate is created in the presence of oxygen. ATP simply put, is the energy which drives the contraction of muscles and enables you to move. It makes sense then that the more Mitochrondria you have, the better your ability to efficiently handle aerobic activities, ie marathoning. And what is the prime driver in increasing Mitochrondria? Long, slow, aerobic running. Take a look at this photo showing the before and after endurance aerobic training taken from a study by Dr. Dave Costill. All those red circles indicate mitochrondria, and as you can see there are many many more after slow aerobic running over time. The more you have, the more you can efficiently deliver oxygen to your Mitochondria and make ATP. Additional benefits of Aerobic Base Building are the recovery benefits it provides from your harder workouts where muscle cells are damaged and strengthening of your muscular-skeletal systems.
