LACTATE THRESHOLD TESTING

Lactate threshold testing goes beyond VO2 Max to reveal how efficiently your body clears lactate during intense exercise, a key factor in sustaining high performance. By identifying your blood lactate thresholds, NYC Performance Lab provides insights to help you train smarter, boost endurance, and optimize results.

What is Lactate Threshold Testing?

Our Lactate threshold test measures lactate concentrations in your blood while you exercise at increasing levels of intensity, identifying the point at which the accumulation of lactate causes fatigue. This test is commonly conducted concurrently with a VO2 Max test, but can also be run independently. A must for any data-driven endurance athlete, lactate threshold testing empowers you to tailor training intensity for maximum efficiency.

Regardless of your fitness or longevity goals, your lactate threshold is one of the most revealing indicators of how efficiently your body performs — and recovers — under stress.

Why DO Your Lactate Threshold Test At NYC Performance LaB?

Accurately assessing blood lactate levels requires detailed understanding of sophisticated training and testing protocols. Also, since a small finger pricks is involved, it’s critical that the facility conducting the testing adheres to the highest standards of cleanliness, hygiene, and professionalism. At NYC Performance Lab, your test will be conducted by a highly qualified exercise physiologist who has successfully executed hundreds, if not thousands, of lactate threshold tests. We are confident you will not find a more comfortable, efficient, and reliably excellent lactate threshold testing experience in NYC (or elsewhere for that matter).

BENEFITS OF THE NYCPL
Lactate Threshold Testing

Pinpoint Training Zones for Maximum Efficiency

Lactate Threshold Testing identifies your precise lactate thresholds, helping you tailor your workouts to optimal intensity levels. This ensures you’re training smarter, not harder, and maximizing the effectiveness of every session.

Personalized Insights for Smarter Training

The data from blood lactate tests offers a detailed understanding of your body’s unique metabolic response to exercise. This enables you to refine your training strategy, improving efficiency and reducing overtraining risks.

Enhance Endurance and Performance

By improving your ability to manage lactate accumulation, you can sustain higher intensities for longer. This gives you the endurance equivalent of a larger fuel tank, allowing you to push past your previous limits.

Gain a Competitive Edge

Athletes with equal VO2 Max levels often differ in their ability to sustain performance. A higher Lactate Threshold gives you a significant advantage by allowing you to perform at a higher percentage of your VO2 Max for extended periods.

what to expect from your LACTATE THRESHOLD APPOINTMENT

The test involves a gradual increase in exercise intensity while small blood samples are collected from a fingertip using a tiny lancet that most people find virtually painless. Our clinicians carefully pace each stage to match your fitness and experience, ensuring you’re challenged but comfortable throughout. Whether you’re an elite runner or building your aerobic base, the process is safe, supportive, and designed to deliver precise, actionable insights about your endurance capacity.

1

Get Changed and Set Up
You'll be wearing a heart rate monitor around your chest and, if you’re also doing a VO2 Max test, we’ll fit you with a wireless analyzer mask (otherwise this part can be skipped). We have multiple mask sizes to accommodate all head sizes and shapes and ensure you're as comfortable as possible. (5 mins)

2

Start Your Test on Your Chosen Modality
You can run on our top-of-the-line Technogym SkillRun Unity 7000 treadmills, cycle on our Wahoo Kickr bike, bring your own bike to use with our connected smart trainer, or use a rowing machine. During the test itself, the difficulty (ie speed, power, and/or incline) will slowly increase until you can no longer continue and your VO2 Max is recorded. (20-30 mins)

3

Review Initial Results
We'll go over your results, put everything in context, and answer any immediate questions you have. (5 mins)

4

Cool Down and Refuel
Catch your breath while we serve you a complimentary "top shelf" sports beverage or snack of your choice (electrolytes, protein shake/bar, essential aminos, etc) (5 mins)

Your Detailed Follow-Up Report
Within a week after your test you'll receive a personalized follow up report with full details, peer benchmarks, and actionable next steps about how to adapt your training based on insights from the test.
