BEHIND THE PERFORMANCE

Evaluation of standard movements

Use of the Myontec’s tools in recovery

Analysis of training load

Monitoring test

Monitoring different exercises

Comparing internal external load

Prof. Mauro Testa Biomoove – Myontec

Myontec

INTERNAL LOAD

Myontec is a Finnish company

Myontec designs and develops wearable systems, hardware and software, for sports analysis and performance evaluation


Overview

INTRODUCTION

Wearable technologies help biomechanics and coaches to monitor athletes without their cooperation in a non-invasive way

Wearable technologies allow continuous training sessions without interruptions

It is possible to prevent injuries by monitoring athletes during their training sessions

Myontec is comfortable and reliable


Overview

MYONTEC’S ADVANTAGES

Myontec’s products are easy to wear

It’s impossible to fail sensors position

Sweat it’s not a problem

The hair does not bother the signal

The possibility to link electromyographic signals (internal load) with inertial sensors (external load)


Overview

WHAT WE READ

We analyze not a singular muscle but the FUNCTIONAL UNITS


Overview

EVALUATION OF STANDARD MOVEMENTS


• As biofeedback

• In postural analysis

Evaluate standard movements in static or dinamic situation

Squat can be a movement to see the angle where iscollected the hightmuscle load

Nordic test with electromyographyPant, we can see differences between two legs and how the players perform the test

Relation ship between movement angles and muscle work

MEASURE - OBSERVATION


Note the level of right hamstring work…………why?

The right side of sacrum iliac joint doesn’t work.

Basic muscle’s activation

Overview

TRAINING LOAD ANALYSIS


Means evaluate by sensor anychanges during training and itscost

Which side of the body is more spreadly used?

Do we have some non balance situation?
