Once you've built Load–Velocity Profiles (LVPs) for your athletes, the next step is understanding how to apply them using velocity decrements (Vdec). This method of velocity-based sprint training is arguably the simplest and most powerful way to individualize sprint programming with the 1080 Sprint, helping you select the exact resistance to match your athletes needs.
What Is a Velocity Decrement (Vdec) in Sprint Training?
A velocity decrement (Vdec) is how much slower the athlete runs compared to their unresisted max speed. Just like velocity-based training in the weight room, the goal isn’t to chase a specific load—it’s to target the right velocity zone that matches your training goal.
Instead of saying “this load feels heavy,” you can now target exact performance outputs:
10% Vdec = ~90% max velocity → works well for late acceleration and technical rhythm
25% Vdec = ~75% max velocity → ideal for resisted drills and mid-acceleration
50% Vdec = ~50% max velocity → max power, sprint-specific strength, early acceleration
Each zone shifts the mechanics and intent of the sprint, allowing coaches to train across the entire force–velocity curve. But the key is this: different athletes need different loads to hit the same velocity decrement. Group averages won’t cut it.
How to Apply Velocity Decrements to Resisted Sprints
1. Start by testing: Use 3–4 loads to build the athlete’s LVP (Learn how here)
2. "Save to Profile": The 1080 software will automatically calculate the loads needed for 10%, 25%, 50%, etc. for that athlete then apply that load to the machine
3. Be consistent: Keep the load the same for a 3–4 week block to track progress over time. Let velocity improvement reflect the athlete's adaptation.
4. Train with intent: Don’t just sprint with random resistance. Use Vdec zones to target the right stimulus at the right time.
Why Vdec Makes Sprint Programming More Precise
Every athlete trains with the same goal, but now they can do it with the load that fits them individually. That’s how you move from training harder to training smarter, with targeted development that gets results.
