Beyond the Speedometer: Why Your VBT Strategy Needs a Load-Velocity Profile

Velocity-Based Training (VBT) is often described as a game-changer for objective training, yet many practitioners only scratch the surface of its potential.

While many coaches use velocity as a simple motivational tool, the true power of VBT lies in individualized load-velocity (L-V) profiling, which allows for precise autoregulation and fatigue management.

The Myth of the Generic Velocity Chart:

A common mistake in the industry is using a generic "velocity zone" chart for every lift (i.e. Speed, Speed-Strength, Strength-Speed, Absolute Strength).Relying on these general spectrums will short-change some lifts and overestimate others because the relationship between load and velocity is highly exercise-specific.

The minimum velocity threshold (V_1RM) —the speed of a maximal effort—changes drastically depending on the movement's biomechanics:

• Bench Press: ~0.17 m/s
• Back Squat: ~0.30 m/s
• Prone Bench Pull: ~0.50 m/s
• Deadlift: ~0.15 m/s

If you use a "squat spectrum" (terminating at 0.30 m/s) to program a bench pull, you are stopping the set while the athlete is still miles away from their true limit. To be precise, you must move beyond general group equations and develop individualized profiles.

How to Create a Load-Velocity Profile: A Step-by-Step Guide

For strength coaches and personal trainers, building a profile is a straightforward process that can be replicated in any facility with a valid VBT device.

1. Determine the 1RM and Establish the V_1RM First, have the athlete perform a traditional 1RM assessment to find their maximum strength. Record the Mean Velocity (MV) of the final successful attempt; this is the athlete's specific V_1RM . If testing a true 1RM is not possible, you can use the established general values for that specific lift.
2. Perform an Incremental Loading Test After at least 24–48 hours of rest, have the athlete perform repetitions at various percentages of that 1RM. A standard protocol includes:

• 3 repetitions at 20%, 40%, and 60% 1RM.
• 1 repetition at 80% and 90% 1RM.
• Crucial Instruction: The athlete must perform the concentric phase of every rep with maximal intent (as fast as possible) for the data to be valid.

3. Record the Fastest Mean Velocity (MV) For the sets involving multiple reps (20–60%), record only the fastest MVachieved. Mean velocity is preferred over peak velocity for profiling because it is more stable across different devices and has a more linear relationship with load.
4. Create the Regression Equation Input the data into a spreadsheet like Microsoft Excel.

• Plot the Relative Load (%1RM) on the X-axis and the Mean Velocity (m/s) on the Y-axis.
• Apply a linear line of best fit.
• The resulting equation (e.g., Velocity=−0.0146(%1RM)+1.722) allows you to calculate the exact velocity for any given intensity in future sessions.

The Shortcut: The 2-Point Method If you are short on time, research supports the 2-point method for upper-body exercises. By recording the MV of a light load (~45% 1RM) and a heavy load (~85% 1RM), you can create an accurate linear regression without the fatigue of a full incremental test.

Precision Programming with Athlete Autoregulation

Once you have this profile, you can move away from rigid weight assignments and toward target velocities that align with % of 1RM. This ensures that every athlete receives the intended physiological stimulus. You now will know based off the athletes individualized velocity profile, if their Mean Velocity for that lift is matching their charted % of 1RM, creating the ultimate fatigue monitoring tool.   

Ready to Take the Guesswork Out of Your Programming?

If you’re ready to move beyond generic charts and start training with the precision of individualized Load-Velocity Profiles, it’s time to get the right tool for the job.

The OVR Velocity device is designed to be the most accessible and effective way to integrate VBT into your daily workflow. For $249 a fraction of the cost of traditional sensors you get a device that magnetically attaches to your rack and provides real-time bar speed on every single rep.

How to Access Your Data and Build Your Profile

Building a professional-grade profile doesn't require a degree in data science. Here is how you can use the OVR system to do it:

1. Download the OVR Connect App: While the device has a built-in display for quick feedback, the OVR Connect app (available on iOS and Android) is where the real magic happens. It provides live data, full session history, and coach dashboards.
2. Run Your Test: Perform the incremental loading test we discussed (sets at 20%, 40%, 60%, 80%, and 90% of 1RM). The app will automatically capture and save every repetition.
3. Export and Profile: Simply open your session history in the app to identify the fastest Mean Velocity (MV) for each load.
4. Create Your Map: Plug those velocities into a spreadsheet (like Microsoft Excel), plot them against the relative load (%1RM), and apply a linear line of best fit. This equation is now your "GPS" for that athlete's training.

Stop guessing and start prescribing. Whether you are a strength coach managing 50 athletes or a personal trainer working 1-on-1, the OVR Velocity gives you the objective data you need to ensure every rep counts.
