Biomechanical Analysis
What your body
needs to excel.
Athlete Profile assesses the specific biomechanical traits that predict elite performance in Long Jump. These aren't generic fitness metrics - they're sport-specific physiological signatures.
Sprint-Power Composite
Approach velocity is the dominant correlate of distance
Elite long-jumpers are essentially specialised sprinters who finish their race on a board. Across 18–22 approach strides they accelerate to 10.5–11.5 m/s in elite men and 9.4–9.8 m/s in elite women, and the regression between final-stride velocity and jump distance accounts for over 70% of the variance in performance. This places horizontal speed and Type IIx output above any throwing-style strength quality, and our SPR assessment captures the maximal-velocity phase that the board itself rewards.
Penultimate-Step CoG Lowering
Vertical impulse is bought by a 4–6 cm hip drop
The defining technical feature of an elite take-off is a deliberate lowering of the centre of mass on the penultimate (second-to-last) ground contact, typically 4–6 cm, paired with a flatter penultimate foot strike. This pre-stretches the take-off leg's hip and knee extensors, lengthens the path over which vertical force can be applied, and lifts the take-off angle into the 18–24° range without bleeding horizontal velocity. Athletes who cannot produce that loading geometry default to a flat take-off near 12°, capping distance regardless of approach speed.
Take-Off Leg Force Tolerance
12–16× bodyweight peak GRF in 100–120 ms
The take-off foot encounters peak vertical ground reaction forces of 12–16× bodyweight, transmitted through the patellar tendon, Achilles, and navicular within the same 100–120 ms window. This is among the highest impulsive loads in athletics and explains the take-off-foot-specific injury pattern of distal Achilles tendinopathy, patellar tendinopathy, and navicular stress fracture. Our CMJ peak-force and rate-of-force-development metrics index whether the take-off leg can absorb and re-express that load without collapsing into knee valgus or rear-foot pronation.
Take-Off Leg Asymmetry
One leg jumps; the other pays the price for imbalance
Long jump is structurally unilateral - every competition jump uses the same take-off leg, producing chronic between-leg asymmetry in eccentric strength, ankle stiffness, and proximal hamstring loading. Asymmetry above 12% in single-leg CMJ peak power or in concentric/eccentric ratios is the leading mechanism behind proximal hamstring strain on the swing leg and stress reactions in the take-off foot. Our bilateral CMJ-asymmetry composite quantifies this gap and is one of the few non-platform measures that reliably tracks it.

assessment report.
Velocity-to-Distance Conversion
A 0.1 m/s gain in final-stride velocity translates to roughly 9–11 cm of jump distance once a competent take-off is in place - speed, not strength, is the primary lever above 7.5 m. Your SPR peak velocity, scaled to maximal-velocity output rather than 10 m acceleration, is associated in observed cohorts with the ceiling your take-off can convert into board-edge distance.
Anthropometric Profile
Elite male long-jumpers cluster at 175–192 cm and 70–82 kg - taller than 100 m sprinters, leaner than triple-jumpers. Long levers add bar reach at take-off and flight; lower body-fat percentages (typically 6–9% in-season) preserve power-to-mass. Our anthropometric profile flags whether limb length and mass distribution favour the velocity-driven board-conversion model or the bounding-driven triple-jump alternative.
Vertical-to-Horizontal Velocity Ratio
At take-off, elite jumpers convert horizontal velocity into a vertical-to-horizontal ratio near 0.40, corresponding to a projection angle of 18–24°. Lower ratios (flat take-off) sacrifice height and flight time; higher ratios bleed horizontal speed and shorten distance. Our CMJ + SPR composite indexes whether an athlete's force-vector profile sits inside the elite conversion band.
Approach Rhythm & Stride Variability
Elite jumpers strike the board with a positional error under 5 cm across competition rounds - a coordination skill, not a power one. Stride-to-stride variability over the last six strides drops below 2% in world-class athletes through visual regulation and trained motor maps. Our coordination metrics capture the rhythmic precision underneath that 5 cm tolerance.
