Lactate Testing
Blood lactate testing helps you train smarter by showing exactly where your training zones should be—based on your physiology, not averages.
As exercise intensity slowly increases, small finger or earlobe blood samples are taken to track how your body handles effort. The results highlight key thresholds that guide endurance training, aerobic conditioning, tempo sessions, and race pacing.
What our blood lactate test reveals:
LT1 and LT2
LT1 and LT2 mark two key intensity points where your body’s response to effort changes. LT1 represents the highest intensity you can sustain while primarily using aerobic metabolism—this is where endurance is built and fatigue stays low. LT2 reflects the point where lactate accumulates rapidly and effort becomes hard to sustain, often associated with race-pace intensity. Knowing both thresholds allows for precise training that improves endurance, speed, and race performance.
Fat Max
Fat Max is the speed or power output at which your body is primarily using fat as its main fuel source. Training at or near this intensity improves metabolic efficiency and endurance by teaching your body to rely less on carbohydrates. This is especially valuable for long-distance athletes aiming to delay fatigue and conserve glycogen during races.
Training Zones
Blood lactate testing allows for highly individualized training zones based on your actual physiology rather than generic formulas. These zones define how hard you should train to target specific adaptations—such as aerobic development, threshold improvement, or high-intensity performance. Accurate zones lead to better workouts, improved recovery, and more consistent progress. Added bonus for coaches: our technology can sync with Training Peaks!
VO2 Max
VOâ‚‚ max is a measure of your body’s ability to take in, transport, and use oxygen during intense exercise. It reflects your aerobic ceiling and helps determine how much work you can perform at higher intensities. While not the only predictor of performance, VOâ‚‚ max provides valuable insight into aerobic capacity and how your body responds to high-intensity training.
Carb Max
Carb Max represents the speed or power where carbohydrates become your dominant fuel source. This typically occurs at higher intensities when energy demands exceed what fat metabolism can supply. Understanding Carb Max helps athletes target race-specific efforts and optimize fueling strategies for hard workouts and competition
Recovery Time
By understanding your peak lactate output and your clearance rate of that lactate, we can get a better understanding of how well your body is adapted to high intensity exercise and make training decisions accordingly.
