Coaching Eye Workshop Series

SESSION 2 - Deceleration

With Dr. Damian Harper


Motion Analysis Example

We are excited to bring you the next online workshop of our series. On Wednesday 27th May 2020 at 12:00, Jonas will be joined by Dr Damian Harper to discuss all things braking strength, eccentric overload and deceleration training. Damian completed his PhD examining “Human Acceleration Performance” has a produced a number of peer reviewed articles. He is also heavily involved in practical coaching through the development training solutions for national and international team sports.

Speedworks is pleased to provide our Coaching Eye workshop series in conjunction with Binary Video Analysis. We have been working with Binary to develop a real fun but functional app for all coaches, therapists and scientists. Subscriptions to Binary can be purchased from the shop.

The app will allow you to collect your own data on step to step changes in sprinting, jumping, deceleration. Times, distances, angles and velocities of joints and body segments can be analysed. You can also manipulate what data you see or don’t see on the screen. e.g 1m split times and knee/hip flexion step lengths in the final 5m of a deceleration, or the ground contact time, step length and hip angular velocity during a flying sprint.

We have worked hard to on making Binary versatile so as to bring an elite biomechanics team to your lab track, pitch, court and clinic. Now with normative data you can start to create your own living lab, and better develop your coaching eye.
After watching the workshop, we suggest you go out and experiment. Go accelerate, sprint, do a 5-0-5 throw, or do some hops and bounds. Just 5-10m in field of view to maintain a quality picture. Record it in slow motion and have a play on the app.

A recording of the webinar will be made available for those who cannot attend on the day after the event has concluded, available on the Education page.

Workshop Information

The workshop took place on Wednesday 27th May 2020 – 12:00-14:00.

During this workshop:

Section 1

  • You will learn how to develop a “coaching eye” for deceleration mechanics
  • We will share with you our rules of thumb when looking at the kinetics and kinematics of deceleration
  • We will go through the characteristics of breaking strength, how to test them and discuss what the numbers mean.

Section 2

  • We will detail the training menu needed to develop all areas of breaking strength
  • We will discuss the types of training programs and progressions need to dove tail acceleration and deceleration training during the preseason.
Buy the
  • Workshop on the fundamentals of acceleration development
  • Tutorial on using the app
  • Speedworks templates for the app


The workshop was recorded as part of live event and is now available for digital purchase.
