Knowing your KPIs is step one. Knowing how to improve them is step two.
This is where most training programs fail. They identify what matters — speed, jump, power — and then immediately reach for the most visually impressive exercise they know. Plyometrics. Band-resisted sprints. Jump boxes. These are not wrong. But sequence and stimulus matter more than exercise selection.
"Physics doesn't change at elite level. Force × Velocity = Power. The training methods that work are the ones that respect this equation."
Improving Vertical Jump
The most common mistake in jump training is starting with plyometrics before the athlete has the strength to produce meaningful force. Plyometrics amplify what is already there. If there is no force capacity, there is nothing to amplify.
The correct sequence:
- Phase 1 — Max strength development. Heavy bilateral and unilateral lower body training. Squats, trap bar deadlifts, split squats. The goal is force production capacity. This is non-negotiable as a foundation.
- Phase 2 — High-velocity power training. Jump squats, loaded jump variations, Olympic lifting derivatives. Moving sub-maximal loads at maximal intent. This shifts the force-velocity curve toward the velocity end.
- Phase 3 — Structured plyometrics. Depth jumps, hurdle hops, bounding. Now the athlete has the force capacity to make plyometric training effective and safe.
Skipping Phase 1 and jumping straight to plyometrics is the most common mistake in team sport programs. It produces fatigue without improving the KPI.
Improving Acceleration
First-step acceleration is fundamentally a force application problem. The athlete who produces more horizontal force in the first ground contact wins the first step. No amount of sprint technique work overcomes a lack of force capacity.
- Heavy strength training — specifically posterior chain and hip extension dominant movements. Force capacity is the ceiling for acceleration ability.
- Max effort sprint training — short distances (10–20m), full recovery between reps. Quality over quantity. Sprinting slowly in fatigue does not improve acceleration.
- Proper resisted sprinting — sled pushes or towing with loads that do not significantly alter sprint mechanics (typically 10–20% bodyweight). Overloaded resisted sprinting teaches slow movement patterns.
Improving Reactive Strength & RSI
RSI — the ratio of jump height to ground contact time — is arguably the most undertrained KPI in team sport. Most jump training improves jump height but does nothing for ground contact time.
Improving RSI requires training specifically at high-stiffness, low ground contact demands:
- Ankle stiffness drills — pogo jumps, fast rope skipping, rapid rebound hops with minimal knee bend. The goal is to reduce contact time, not jump higher.
- Depth jump progressions — drop from a box and immediately rebound. Emphasis on minimal ground contact, not maximal jump height.
- Fast reactive plyometrics — hurdle hops, low box reactive jumps. Progressed over weeks as contact time decreases.
Improving Repeat Sprint Ability
Repeat sprint ability is not just about being "fit." An athlete can have excellent aerobic capacity and still see dramatic sprint quality drops across repeated efforts. The specific adaptations required are different from general conditioning.
- Repeated sprint training — sets of 5–8 maximal sprints with short rest (20–30 seconds). Specifically targets the metabolic and neuromuscular demands of repeated explosive efforts.
- Aerobic power intervals — longer efforts at high intensity to develop the aerobic system's contribution to recovery between sprints. 30-15 Intermittent Fitness Test protocol is a gold standard here.
- Fatigue resistance exposure — training sessions that deliberately expose the athlete to the quality degradation under fatigue, then training to maintain output.
Every method listed here has one thing in common: it targets a specific physical mechanism, not a general "work harder" stimulus. That specificity is what makes it a gold-standard method rather than just hard training.
