Lactate Threshold Testing


This week I completed a bike and run lactate threshold testing (LT - for short). These tests have been described as "one of the most important physiological benchmarks for successful athletic training," and "Sports science research has proven that training within one's lactate threshold determined training zones is the most effective and efficient way of improving one's athletic ability." The main goal of the testing is to
  • Learn your true five training zones.

  • Determine your true maximum heart rate and power output/pace on the bike and the run.  

  • If you have never had the test done its actually quite fun, except that you get poked w/a needle every 3 minutes so they can test your blood. By the end, my left fingers reminded me of minced meat, but I had hardly noticed it. The other thing is that they strap a mouth piece over your face to measure your O2 consumption. I felt like I was using a scuba rebreather. My results from the test really surprised me. I always thought that I was a good cyclist, but the test clearly showed me that I am a classic example of spending way too much time in the middle zones and not enough time either at an easy pace or a hard pace. So I've got to work on that. On the run, I had a more even curve and had a much higher O2 consumption, and I actually maxed out the speed on the treadmill that we were using. That felt pretty cool.

    In addition to the LT testing, they also pointed out that my left foot slightly protinates to the left, which could be why the only times I have been injured (strained hamstring and knee pain) have only been on my left leg. To help prevent and correct this, they showed me different foam roller exercises and strength workouts. I also measured my BMR and found out how many calories I burn during working out. Overall the experience was eye opening. I found that on a normal day I burn aprox 2000 calories, but if you add in just an hour of working out that gets bumped up to 3000. So on some days when I'm working out 3-4 hours, I have to eat upwards of 5000 calories! Wow, I had no idea. I guess I need to eat up. I want to give a BIG THANKS to Terry and Kim who were the ones who administered and supervised the testing. They really are the best. Thanks again guys and I can't wait to implement these results into my training for 2012.
