Sample report
This is a real assessment, not a mock-up. The score, the limb split, the three domains and all twelve checks are what the tool recorded for one athlete on one run. The athlete is not named.
The figures are drawn from that athlete's own frames rather than shown as photographs, because the frames belong to her. A report you receive shows your athlete's actual frames against every check.
Faults
Very poor
Bramah considers 6 or higher sub-optimal.
10 faults out of 12. Lower is better.
Every fault belongs to one of three patterns.
how steady the hips and lower back stay
what the leg does behind the body
landing with the foot too far ahead
The frame each judgement was made from, in stride order.
as the foot leaves the ground
Does the athlete appear to be in excessive extension?
Trailing hip ≥45° from vertical + fully extended knee.
at top speed, mid-flight
Is the heel of the trailing limb above the calf of the trailing leg?
Shin should not be higher than parallel with the floor.
Does the athlete appear to rotate excessively through the trunk?
Large arm movements, trunk twisting, upper arm/shoulder visible on far side.
Does the athlete appear to be in anterior pelvic tilt or lumbar extension?
Excessive lower back arching, elevated chest, "bum behind the body".
as the leg swings forward to land
Is the knee of the trailing leg behind the gluteal muscles?
the instant the foot lands
Does athlete appear to have increased forward lean?
>15° from vertical line drawn from greater trochanter to C7.
Does there look to be an increase in anterior pelvic tilt or lumbar extension?
Excessive lower back arching, "bum behind the body".
Is the gap between the thighs >20° or the trailing knee behind the back?
A line is drawn horizontally from foot contact to the CoM. Is there space for another foot?
Does the shin look extended?
Ankle joint center in front of the knee.
Is there a visible gap between forefoot and floor OR heel and floor?
Excessive heel strike or forefoot strike.
with the body over the foot
Is there increased knee flexion / ankle dorsiflexion?
"Sinking" into stride, "sitting down", knee translating over toes with foot flat.
First assessment. The number earns its meaning at the next one.
Re-assess in 4 to 6 weeks. A change of less than 1 point is inside the test's own margin of error, so real progress shows as a move into a different band.
Both legs were scored from one clip, filmed from the right. The left leg was furthest from the camera, so its back-side and overstride checks are less certain than the right leg’s. The lumbo-pelvic checks are unaffected either way. Filming a second run from the other side removes the doubt.
Both limbs read the same. The 1-point difference is inside measurement error for a two-limb comparison, which needs 3 or more.
For context: in Bramah’s cohort right limbs scored about half a point worse than left on average, so small side differences are normal.
Measurement error is about 1 fault, so a change under 2 may not be real.
This test is not ours. It was published by Bramah, a sports scientist who scored 136 professional footballers to work out what a typical result looks like.
Bramah · 136 elite footballers · mean 4.2 (men) / 3.8 (women), SD 2.7. Elite footballers, not school sprinters, so treat this as a reference point, not a target.
S-MAS · Tool and reliability: Bramah et al., Am J Sports Med 2024;52(6):1608–16. intra-rater ICC 0.83, inter-rater 0.80, SEM ±1. Injury association: Bramah et al., Br J Sports Med 2025. Each point ≈ +33% hamstring-injury rate (IRR 1.33, 95% CI 1.01–1.76), per limb, associative not causal. Coaching feedback, not a medical diagnosis.
