CARDIOMETABOLIC EXERCISE PROFILES
Cardiometabolic testing evaluates the integration of cardiovascular and metabolic function, providing data to guide targeted training and health interventions.
Endurance Markers
Metabolic testing can identify or estimate key physiological markers—such as VO₂max, anaerobic threshold (AT), aerobic threshold (AeT), and FatMax—that provide valuable insight into your fitness level and overall health.
Testing Options Overview
To accurately measure your endurance fitness and training needs, we recommend the following options—starting with the gold standard:
✅ Primary Option: Lab Testing (Recommended)
Metabolic Fitness Testing – Cardio-Metabolic Exercise Profile (CMP)
This lab-based test measures how your body responds to exercise, including heart rate, power/speed, ventilation, and fat burning. It helps define precise heart rate and power zones based on your personal physiology—not generic formulas.
Identifies key fitness markers: VO2max, aerobic/anaerobic thresholds, fat oxidation
Ideal for creating accurate, personalized training zones
👉 If you're in Southern California, you can complete this testing at our lab. For others, we recommend finding a qualified performance testing lab in your area.
Alternative Option 1: Lactate Testing
A second lab-based method involving blood samples to identify training thresholds. Slightly more invasive but highly effective for tracking adaptations and setting training zones.

Alternative Option 2: Talk Test (At-Home Assessment)
Use the Talk Test Protocol to estimate your anaerobic threshold (VT2) heart rate and power/speed at home. While less precise than lab testing, this method provides a reasonable estimate for setting training zones.
Tools provided: Bike and treadmill test guides
Best for: Individuals without access to lab testing
Optional support: Perform it with a partner or get remote assistance from our team

Alternative Option 3: Field Test (FTP/FTHR)
This 20-minute self-directed time trial estimates your Functional Threshold Power (FTP) and Functional Threshold Heart Rate (FTHR)—commonly used by cyclists and experienced athletes.
Requires a flat course, heart rate monitor, and power/speed sensor
Ideal for: Intermediate to advanced athletes with low injury risk
Best used when lab testing isn’t available
How to Use This Information
During training phases, retest every 8 weeks
In between, consider monthly field tests
At minimum, complete annual testing to keep zones and benchmarks updated
All three methods help identify your training thresholds and fine-tune your zones for more effective endurance training.
