當我有資格馮實力玩波馬先算....我又享受慢跑,又享受越跑越快,自自然然
Quote:I came from a swimming background, which in the 70s and 80s when I competed was a sport that lived by the No Pain, No Gain motto. My coach would give us workouts that were designed to push us to our limit every single day. I would go home dead, sleep as much as I could, then come back the next day for another round of punishing interval sets.
It was all I knew. So, when I entered the sport of triathlon in the early 1980s, my mentality was to go as hard as I could at some point in every single workout I did. And to gauge how fast that might have to be, I looked at how fast the best triathletes were running at the end of the short distance races. Guys like Dave Scott, Scott Tinley and Scott Molina were able to hold close to 5 minute miles for their 10ks after swimming and biking!
So thats what I did. Every run, even the slow ones, for at least one mile, I would try to get close to 5 minute pace. And it worked
sort of. I had some good races the first year or two, but I also suffered from minor injuries and was always feeling one run away from being too burned out to want to continue with my training.
Then came the heart rate monitor. A man named Phil Maffetone, who had done a lot of research with the monitors, contacted me. He had me try one out according to a very specific protocol. Phil said that I was doing too much anaerobic training, too much speed work, too many high end/high heart rate sessions. I was forcing my body into a chemistry that only burns carbohydrates for fuel by elevating my heart rate so high each time I went out and ran.
So he told me to go to the track, strap on the heart rate monitor, and keep my heart rate below 155 beats per minute. Maffetone told me that below this number that my body would be able to take in enough oxygen to burn fat as the main source of fuel for my muscle to move. I was going to develop my aerobic/fat burning system. What I discovered was a shock.
To keep my heart rate below 155 beats/minute, I had to slow my pace down to an 8:15 mile. Thats three minutes/mile SLOWER than I had been trying to hit in every single workout I did! My body just couldnt utilize fat for fuel.
So, for the next four months, I did exclusively aerobic training keeping my heart rate at or below my maximum aerobic heart rate, using the monitor every single workout. And at the end of that period, my pace at the same heart rate of 155 beats/minute had improved by over a minute. And after nearly a year of doing mostly aerobic training, which by the way was much more comfortable and less taxing than the anaerobic style that I was used to, my pace at 155 beats/minute had improved to a blistering 5:20 mile.
That means that I was now able to burn fat for fuel efficiently enough to hold a pace that a year before was redlining my effort at a maximum heart rate of about 190. I had become an aerobic machine! On top of the speed benefit at lower heart rates, I was no longer feeling like I was ready for an injury the next run I went on, and I was feeling fresh after my workouts instead of being totally wasted from them. |
