How to Build an Acceleration Training Program: Complete Step-by-Step Guide

Research by Morin et al. (2012) established that the ability to produce horizontal ground reaction force — not just total force output — is the primary mechanical discriminator between faster and slower sprinters during the 0–30 m acceleration phase. Athletes who produced a greater fraction of their total force horizontally ran faster first steps and covered 10 m in less time, regardless of absolute leg strength. This finding reshaped acceleration training: it is not enough to make athletes stronger vertically; the training must specifically develop the ability to project force forward and backward at acute body angles.

This guide shows how to build an acceleration training program grounded in horizontal force production mechanics, with specific sprint drills, complementary strength exercises, a weekly structure, and an objective progress-tracking system using velocity-based training tools.

The Science of Acceleration

Acceleration is the rate of change of velocity from zero or low speed. In team sports, most accelerations occur over 5–15 metres and last 1.0–2.5 seconds — distances where athletes never reach maximum velocity and where horizontal force application dominates.

Three mechanical parameters define acceleration quality:

• Ratio of Forces (RF): The proportion of resultant ground reaction force applied horizontally versus vertically. Elite sprinters achieve RF values of 45–55% at the first step, declining toward 15–25% at 30 m. RF is trainable and responds to specific technique and strength interventions.
• Step rate and step length: Early acceleration relies primarily on step length increases (greater force impulse per step); after step 8–10, step rate becomes the primary velocity driver. Programming should address both, with different drills targeting each phase.
• Contact time: Shorter ground contact times indicate better reactive strength — important for the transition from pure acceleration (steps 1–6) to the speed-strength phase (steps 7–15). Contact time under 120 ms at maximum velocity is a performance benchmark for elite-level sprinters.

Force-Velocity Profile for Sprinters

Samozino et al. (2016) demonstrated that individual force-velocity (F-V) profiles — the balance between force production capacity and velocity production capacity — directly predict sprint performance deficits. Athletes with an overly force-oriented profile (too much maximal strength relative to speed) benefit more from speed training; athletes with a velocity-oriented profile benefit more from strength training.

The practical application: before building an acceleration program, measure the athlete's F-V profile. A load-velocity profile from weighted sprints or from a standard bar velocity test allows categorisation:

This profile-based approach prevents the common error of prescribing identical acceleration programs to athletes with fundamentally different underlying mechanical limitations.

Sprint Drill Selection and Technique Cues

Effective acceleration technique requires a forward body lean of 45–60° at the first step, toe-off with full hip extension, and a powerful backward "push" of the stance leg. The following drills develop these mechanics progressively:

Phase 1: Mechanical Foundations (Weeks 1–4)

• A-march and A-skip: Develop hip flexion timing and arm action without speed demand. Key cue: "tall hips" — maintain hip extension through toe-off.
• Wall drill acceleration: Athlete leans against wall at 45–50° and performs alternate leg drives at increasing frequencies. Directly trains the lean and push angles of acceleration without locomotion demand.
• Falling starts (3–5 m): Athlete falls forward from standing and must catch themselves with aggressive first steps. Ingrains reflexive horizontal force application.

Phase 2: Speed Application (Weeks 5–8)

• Resisted sprint (10–20% body weight sled): Overloads the horizontal force production requirement. Sprint Research by Morin et al. (2017) showed 5° or greater improvement in stride angle with 8 weeks of resisted sprinting at 20–30% body weight resistance.
• Block starts (if applicable): Develop starting strength and first-step mechanics under competition-specific conditions.
• Flying 10s: Sprint through a 10 m zone at maximum velocity after a 20 m build-up. Trains speed-strength transition zone.

Strength Exercises That Transfer to Acceleration

Acceleration-specific strength training must develop horizontal force production capacity — not just vertical force. The following exercises have demonstrated direct transfer to sprint acceleration outcomes in peer-reviewed research:

Weekly Program Structure

Acceleration development requires both sprint quality and strength quality sessions, with adequate recovery between sprint-intensive days. A 3-session/week structure is optimal for most team sport athletes:

Session 1 (Mon/Tue) — Sprint Mechanics + Strength

1. CNS warm-up: 10 min dynamic + A-skips + wall drills
2. Sprint block: 6–8 × 20 m accelerations from standing, 3–4 min rest between reps
3. Strength: Trap bar jump 4×4 at 50% 1RM + Hip thrust 3×6 at 75% 1RM

Session 2 (Wed/Thu) — Heavy Strength

1. CMJ readiness screen (3 jumps)
2. Lower ME: Trap bar deadlift or Bulgarian split squat 3–5RM
3. Accessory: Nordic hamstring curl 3×6, Hip flexor strengthening 2×10

Session 3 (Fri/Sat) — Resisted Sprint + Power

1. Sprint block: 4–6 × 20 m resisted sprint (15–20% BW sled)
2. Contrast: 4–6 × 20 m free sprint immediately after sled removal (1 min rest)
3. Power: Split squat jump 4×4, maximum velocity intent

12-Week Progression Model

Tracking Acceleration Progress with Data

Three categories of data provide a complete picture of acceleration training progress:

Sprint Performance Metrics

• 10 m split time: Primary outcome measure for pure acceleration phase. Target improvement: 0.03–0.08 s over a 12-week program in trained athletes.
• Peak velocity in 0–30 m: Secondary indicator of speed-strength transition quality. Measurable with GPS or 800 Hz IMU sensors.
• Resisted vs. free sprint differential: If the gap between resisted (sled) and free sprint time narrows over the program, horizontal force production capacity is improving relative to free speed — a direct signal that the training is working.

Strength Progress Metrics

• Bar velocity at set loads: Weekly velocity testing at 60–80% 1RM for hip thrust and trap bar exercises tracks strength progress without regular 1RM testing, which creates unnecessary fatigue.
• CMJ height trend: Weekly CMJ height reflects neuromuscular power development. An upward trend over 8+ weeks confirms speed-strength adaptations are occurring even when sprint times plateau.

Weekly Review Protocol

Review sprint and strength velocity data weekly. Compare the current week's 10 m time and bar velocity profiles against the 3-week rolling average. An improvement in bar velocity at set loads without improvement in sprint time indicates a delayed transfer — continue the program. Sprint time improvement lagging strength by more than 3 weeks suggests insufficient sprint volume or a technique limitation requiring coaching intervention.
