What is Biomechanical Analysis?

Biomechanical Analysis is the TrainersEye clinical muscle assessment. A clinician records the subject profile, ISAK skinfolds, breadths and girths, and the circumferences of 25 body zones; the analysis engine calibrates them against the TrainersEye clinical reference database — 27 calibration profiles — and returns bilateral symmetry, proportionality, a development score and a composite risk tier, with a corrective prescription. The output is an eight-page clinical biomechanical report with a report ID, ready to print or send. Reference bands derive from ISAK protocols and peer-reviewed anthropometric equations.

25 zones, ISAK method

Anterior zones 1–13 and posterior 14–25 in centimetres, plus triceps and subscapular skinfolds, biacromial and bi-iliocristal breadths, arm and calf girths.

Calibrated, not guessed

Every zone is measured against the ideal for the chosen profile — general fitness, professional athlete, elite bodybuilder or custom — from a 27-profile calibration database.

Symmetry, proportion, risk

Left–right asymmetry index with clinical bands, structural ratios against acceptable bands, a development score out of 100 and a composite risk index out of 40.

A clinical report

Eight pages: cover and subject block, executive summary, anthropometric profile, symmetry analysis, proportionality and risk, corrective prescription and references — with a report ID.

Where to find it

Open the TrainersEye app, go to the Dashboard and tap Biomechanical Analysis. It is part of the Pro plan.

Biomechanical Analysis · Open the tool
Part 1 · Getting started
Step1

Open the tool

From the Dashboard, tap Biomechanical Analysis. It is a Pro-plan tool on the TrainersEye Clinical Platform.

TipThe plan badge beside the title shows Pro, so you know the tool is included in your subscription.
Biomechanical Analysis · Read and accept the disclaimer
Part 1 · Getting started
Step2

Read and accept the disclaimer

Read the medical disclaimer — evidence-based analysis, not a substitute for diagnosis; physician clearance for clients with pre-existing conditions — then tick the consent box. The assessment unlocks.

TipThe consent is part of the clinical record: read it with the client, not for them.

Step3

References, print and report

The three header buttons open the references behind the calculations, print the assessment, and open the report document.

TipPrint and the report become useful once the analysis has run; the references are there from the start.

Part 2 · The assessment
Step4

Subject profile

Choose the user profile — general fitness, professional athlete, elite bodybuilder or custom — and the biological sex. The profile is matched against the 27-profile calibration database; anthropometric norms vary by sex.

TipPick the profile the client trains as, not the one they aspire to — the ideals are calibrated to it.

Part 2 · The assessment
Step5

Client and clinician

Enter the client's name, age, height and weight, then your own name and credentials as the assessing clinician — for example MMSx-BODYGNTX or NASM-CES.

TipName, age and clinician are required fields; the analysis button stays locked until they are complete.
Biomechanical Analysis · ISAK anthropometry
Part 2 · The assessment
Step6

ISAK anthropometry

Record the triceps and subscapular skinfolds in millimetres, the biacromial and bi-iliocristal breadths and the relaxed arm and calf girths in centimetres, each at its ISAK landmark.

TipTake the mean of three consecutive readings, subject relaxed, tape perpendicular to the segment with zero compression.

Step7

The 25 zones

Enter the circumferences in centimetres — Anterior 1 to 13 from chest width and deltoids to calves, Posterior 14 to 25 from upper trapezius to hamstrings. Each field shows its expected range.

TipMeasure at the landmark of greatest segmental girth, and measure left and right the same way — symmetry depends on it.

Step8

Watch the progress

The progress bar counts the 37 fields; it fills as you go and shows how many remain.

TipEvery zone entered adds to the report; blanks print as dashes and drop out of the scoring.

Part 2 · The assessment
Step9

Signature and notes

Sign in the signature box and save it; add clinical observations, history and the intended training context in the notes.

TipThe signature and notes print in the report's attestation — they are what makes it a clinical document.

Step10

Perform the clinical analysis

Tap Perform Clinical Analysis. The engine calibrates all 25 zones against the reference database — bilateral symmetry, proportionality, development scoring and corrective prescription.

TipThe button unlocks when the required profile and client fields are complete.

Part 3 · The report
Step11

The report cover

The report opens with the subject block: subject, age and sex, height, weight and BMI, calibration profile, date, clinician and certification, development grade, composite risk tier and the report ID.

TipQuote the report ID in any correspondence; it ties the report to this assessment.

Step12

Read the analysis pages

Executive summary with development score, body-fat estimate, ASM and risk tier; anthropometric profile measured against ideal; bilateral symmetry with the asymmetry index; proportionality, ratios and risk; then the corrective prescription and references.

TipThe disposition line on page two is the sentence to act on — high risk means clinical or physiotherapy evaluation before high-load programming.
