Since my mentor and I haven't discussed our testing protocol to determine and measure lactate threshold in our subjects, I decide to research on more information of how other researchers and athletes measure lactate threshold.
According to the "Lactate Threshold Testing Protocol" article by Elkhart Valley Cycling Club, lactate threshold measurement is a key element in examining and improving athlete performances because higher lactate threshold indicates more energy produced. Testing protocol with treadmill is listed as below: Warm up for about 15 minutes, and determine an optimal starting pace. Set the treadmill to a 3% incline, and with every 90"
Use the lactate meter to get blood sample to measure the lactate concentration for each interval, right before where lactate concentration stays about the same (gets terminal) is the lactate threshold. This is a sample of treadmill testing protocol, but my mentor and I will develop and advance another version of protocol that is more helpful for our experiment.

RECAP: How is lactate produced?
Lactate is produced after glycolysis in the process of fermentation, and promptly becomes lactic acid by binding to a hydrogen ion. If glucose is broken down to pyruvate at very high rate, pyruvate begins to accumulate inside muscle cells, and lactic dehydrogenase convert pyruvate to lactate. Q: Is lactate a bad thing?
MYTH: Lactate can not be cleared out? Lactate is rapidly removed form blood once it appears, and lactate level does not rise as high as glucose concentration does because of its constantly buffer. TRUTH: Lactate is helpful for human body. Citation: How increasing your lactate threshold will improve your fitness and performance, Lactate Threshold Article, Owen Anderson, 2017. |
