So what is Threshold Power?
Lactate threshold (LT) is where at a given intensity your lactate begins to accumulate, this is an extremely powerful predictor of an athletes endurance performance ability. This is because although an athletes cardiovascular fitness level as in their maximal oxygen uptake (VO2Max) sets the upper limit to their rate of aerobic energy production, it is their metabolic fitness as in their LT that determines the percentage or fraction of their VO2Max that can be utilized for any given period of time. The physiological factors determining LT are complex, but in this context blood lactate levels essentially serve as an indirect marker for biochemical events within exercising muscle. Specifically a person’s LT reflects the ability of their muscles to match energy supply to energy demand, which in turn determines the fuel mix (i.e., carbohydrate Vs fat) used and the development of muscle fatigue.
What you will get from the test?
So why get tested?
A field test is a real world and scientifically supported method for cyclists to determine their threshold power. It is performed by the cyclist going as hard as they can for 20 minutes. The average wattage from the test is used to calculate the riders’ threshold power for 1 Hr. A power profile test will assess whether you are adapting positively to the training (ie getting stronger). The first power profile test you do gives you a benchmark of what power you can achieve for 20 minutes. Subsequent tests allow you to assess where you are improving. Many athletes find it motivating to be tested regularly as it is a way of measuring your improvement in fitness and strength. You can also look at how your power and power/weight for each effort compares to athletes at International and National level. Depending on what races you have and what your training workload is like, we recommend being tested every 1-2 months to ensure your prescribed training is working.
