Fitness Testing (LT and PPT)

LT (Lactate Threshold)

Blood Lactate testing has been a hallmark of Exercise Physiology for decades and when tested and applied correctly, can provide an excellent marker/indicator of the conditioning level of an athlete. The value of understanding the profile of Lactate in the blood is that it represents a biomarker of metabolic activity. Since Lactate is produced as a consequence of energy production, measuring it in the blood through a gradual ramp in intensity can provide valuable information on the individual athletes Aerobic and Anaerobic systems.
At C-Velo, we have long used Field Based testing as a surrogate for the Lactate Threshold /estimate of the athletes Functional Threshold Power (FTP). This was designed to create an easy non invasive method to determine the sustainable power an athlete can hold before their aerobic system can no longer process the lactate fast enough and ultimately lead to fatigue. Training is then designed and zones established to improve this metabolic system so that the athlete can hold higher levels of power sustainably and theoretically improve performance. This has served us well, and we have established reasonably good results from a diversity of athletes over the years. However, there are inherent problems with field testing, and with the availability of portable lactate meters, we can now conduct a more physiologically accurate assessment of Lactate levels and the maximal lactate steady state (MLSS).

We can conduct this test in approximately 30min, and requires a small finger stick for a drop of blood each 4min during a graded ramp of intensity. The protocol is sub-maximal and therefore much easier than an all out time trial or ramp to exhaustion. Athletes will receive a form to show the lactate curve with a further estimate of the threshold as lactate accumulates in the blood to a certain level. This can then be utilized as representative of the power an athlete could sustainably hold. Training zones utilizing Training peaks recommendations for endurance, tempo, Threshold, VO2 max, and Anaerobic Capacity are then based off percentages of the power and Heart Rate at MLSS. These zones will be input into the athletes database at C-Velo for training and be provided to the athlete for their own training.

Physiologic Profile Testing (PPT)

While assessing the power at MLSS is valuable, there are also limitations to the information this provides the coach/athlete as it relates to the complete physiologic profile that contribute to performance and conditioning . For athletes with goal events, the Physiologic Profile testing protocol, analysis, and training plan is a more comprehensive approach to better define the capability of the individual athlete and guide appropriate training toward optimal performance. In collaboration with Shannon Grady, MS and Founder of GO! Athletics, C-Velo will conduct controlled continuous testing that utilizes Power, Heart Rate, and Blood Lactate to measure system capacities in the areas that are important to the events in which the athlete is competing

    • -Comprehensive physiological evaluation with C-Velo Coaches in collaboration with Shannon Grady of Go Athletics.
    • -Assesses System strengths, weaknesses, rates, and capacities
    • -Recommendations for individualized, optimal training phases and parameters
    • -Monitors physiological functioning and System responses to training
    • -Provide a training calendar and training system phasing leading up to goal event
