The Secret to Unlocking your Energy with Blood Lactate Testing



How can you benefit from a Blood Lactate test?

  1. Unlock underdeveloped energy systems. Testing your Blood Lacate Thresholdwould reveal where underdeveloped energy systems are in the body, allowing an increase in blood lacate production and giving you access to untapped energy.
  2. Prevent muscle soreness. Increasing the production of blood lacate aids in preventing acidosis, by transporting positive hydrogen ions that are thought to be the primary cause of muscle acidity out of the muscles.
  3. Prevent muscle fatigue. Increasing the formation of blood lactate cells reduces muscle acidity, helping you feel better and recover faster after an intense workout so you can continue your plan to reach your health goals.


What is Blood Lactate Threshold?



As exercise intensity increases, the amount of oxygen available decreases and some pyruvate (what supplies energy to cells when oxygen is present) is converted to blood lactate instead. The rest of the body (other muscles, liver, and heart) usually limits the production of blood lactate. However, as exercise intensity increases, the body’s ability to remove the blood lactate and covert back to glucose is overwhelmed and an increase in the blood lactate level occurs. This event is referred to as the onset of blood lactate accumulation (OBLA). Research studies have used the corresponding heart rate to the OBLA as the Blood Lactate Threshold, but highly conditioned athletes may have a higher threshold. This threshold is a good determination of maximum exercise intensity a person can hold for a longer period of time.

Why is Blood Lactate Threshold testing important?

One key component in obtaining optimal health is by improving cardiovascular fitness. Blood lactate values help your trainer to determine more accurately the correct training intensity to increase power and endurance versus using heart rate response to exercise testing alone. By testing your blood lacate, your trainer can determine your specific heart rate training zones. As a result, your trainer can adapt your cardio training program to target underdeveloped energy systems to help you reach your goals by defining the right exercise time and intensity.

How is the Blood Lactate Threshold measured?



Depending on your current fitness program and/or health status, the testing is conducted on either an Aerodyne bike or treadmill. Both are standardized, graded tests with added blood lactate testing component. Blood lactate testing is done with a relatively painless prick of the finger or earlobe. As a person progresses through the graded exercise test, the intensity will slowly increase at each level/minute. The blood lactate is measured at the end of each level starting about mid-way through the test.

Blood lactate increases incrementally with exercise intensity. When you achieve a certain intensity where blood lactate increases exponentially and cannot be converted back to glucose for energy due to a decrease in available oxygen, you are crossing the “Lactate Threshold”. Fatigue onset is rapid above the Lacate Threshold, but well-trained individuals can sustain efforts just below this Threshold for hours. To increase how long you can maintain your highest output during cardiovascular exercise, you must increase your power at Lacate Threshold and strive to raise your Lacate Threshold to your highest genetic potential. 

How can you improve your Blood Lactate Threshold?

Schedule a blood lactate test with a qualified professional like one at our Kinesics partner facility, FITT, who can properly perform the testing and provide you with an accurate exercise plan. You can increase their Blood Lactate Threshold to the upper limit of their genetic potential through following a well-designed training program that includes the development of greater cardiovascular abilities, progressions and re-testing.
