Sport science · Performance diagnostics

Where a performance limit originates — and how much room is left.

Data, not impressions.

Assessment and athlete profiling for clubs, federations and individual athletes — from sprints and jumps to team sports. Reliable, repeatable measurements, not impressions.

Open
Load–velocity

Load–velocity profile (sled)

From your sprints with and without a sled: the individual load–velocity line and the training zones (technique, speed-strength, power, strength-speed).

Open
Jumps & reactivity

Jump & reactive strength

CMJ and SJ height from flight time, RSI and DRI in the 10/5 test, and optimal drop height from the incremental drop jump.

Open
Sprint · profile

Acceleration profile

From 10 m splits: how the athlete performs off the blocks and in transition relative to their own maximal velocity, the margin in seconds and where to act first.

Open
Start · blocks

Block setting from anthropometry

Distances computed from lower limb length, Cormic index and comparison with the current setting. Including the condition the data imposes: who the rule works for and who it does not.

Open
Sprint · force-velocity

Sprint force-velocity profile

Pick the distances you measured, from 30 metres up: the mono-exponential model returns the acceleration curve and the horizontal force-velocity profile — F0, V0, Pmax and mechanical effectiveness — with the residual of every timing gate.

About us

Vires Performance

Vires Performance is a consultancy specialised in sports performance diagnostics. We work with clubs, coaching staff, athletes and federations to find where a performance limit originates and turn it into room for improvement — in sprinting and jumping in track and field as much as in team sports.

We combine cross-disciplinary expertise, a solid scientific foundation — in dialogue with international research — and the ability to bring it onto the field. That background was built in high performance, from professional Serie A football to international coach education with the Sports Authority of India, and in applied research. Data is not the destination: it is the instrument for deciding better, reducing injury risk and building development pathways that fit the individual.

In practice: all-round performance diagnostics for individual and team sports, velocity and biomechanics analysis, and direct coaching of track sprinters — with field testing, step-by-step biomechanical analysis, accurate kinematic analysis and estimated kinetics. We work out of Lombardy, with testing already carried out in Tuscany and Sicily and international work in India.

Sport Scientist & S&C Coach

Sport scientist and strength coach specialised in sprinting, biomechanics and field-based functional testing. Master's degree in Sport Science, Technique and Teaching. Former technical director of a university gym, now S&C coach in track and field and sport scientist. He works closely with coaches, looking for answers through in-depth test-based analysis — and builds the tools that let coaches train better.

Sports Biomechanist · Sport Scientist & S&C Coach

Biomechanist and strength coach with experience in high performance and international coach education, specialised in field biomechanical analysis and physical preparation for sprints and jumps, working with youth, adult and elite athletes. BSc in Sport and Exercise Science (2019) and MSc in Sport Science, Technique and Teaching (2021); Periodization Sport Master Trainer certification (ISCI). International experience at pre-Olympic camps in Spain and Cuba with national athletics teams; since 2016 sprint coach (60–400 m) at Atletica Lecco – Colombo Costruzioni and consultant for Compex Italia. In 2022/2023 he worked in Serie A with Hellas Verona as youth S&C coach and first-team return-to-play specialist. In 2026 he was an international speaker at the strength and conditioning symposium for sprints and jumps in Kerala, India, invited by the Sports Authority of India and the Athletics Federation of India.

method

Data, not impressions

Every recommendation comes from measurements that are repeatable and comparable over time, not from what the eye thinks it saw.

sources

Primary literature

Choices rest on the original studies and on validated criteria, keeping what can be cited separate from what is inference.

tools

Low cost, high validity

Affordable instruments, checked against reference methods: low outlay, measurement rigour.

Research & collaborations

Method

Vires's work joins field practice with research: a database of 4886 international races with 10 m splits for sprint profiling, the validation of low-cost instruments against reference methods, and coach education.
