VO₂max should be targeted after improving anaerobic capacity. Even though VO₂max is considered an aerobic factor that represents the maximum capability of your cardiovascular system to supply oxygen to the working muscles, it is often unrecognized that the running speed at which VO₂max occurs includes a large dependence on anaerobic metabolism. In other words, when …
Capillaries, the smallest vessels of your vascular system, traverse your muscle fibers, leading to places deep inside your muscles. Think of capillaries like highways. With many highways in a city, you don’t need to drive far on local roads to get to your destination. You get off the highway at one of its exits, and …
Your Achilles tendon, named after the hero of the Trojan War and the greatest of all Greek warriors in Greek mythology, is the strongest tendon in your body. Your Achilles tendon, which connects the calf muscle to the heel bone, stores energy when your foot lands on the ground, like a tight rubber band when …

Running a marathon as fast as you can takes a long time to recover from, more than people realize, in large part because it causes a lot of muscle fiber damage. Even after 4 weeks after a marathon, damage is still present. My guidelines for how to recover and return to running after a marathon. …
Many endurance sports nutritionists claim that runners should spare their limited store of carbohydrate by trying to rely on fat for as long as possible, and possibly by becoming “fat adapted.” However, marathon runners can actually run faster by relying on carbohydrate for as long as possible in the race. As was first discovered more …
Ever been told that running in the heat is like running at altitude? Haha. It’s not. The reason why you run slower at altitude is because of less oxygen delivery to skeletal muscles because of the lower partial pressure of oxygen in the air. The reason why you run slower in the heat is because …
I once dated a girl who had a thing for my calf muscles. Seriously. Calf muscles. She may have been on to something. Did you know that the energy cost of calf muscle contraction in highly trained runners is nearly 25% of the total metabolic cost of running? In recreational runners, it’s 40%. That’s a …

I went to Tambach track overlooking the Great Rift Valley in Kenya to do VO₂max intervals at 6,400 feet. Since the Kenyan athletes don’t typically do intervals on Mondays, it was nice to have the track all to myself. The defining characteristic of altitude is a lower barometric pressure, which keeps decreasing the higher up …
