Coaching Eye Workshop Series

PART 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.
When you purchase the workshop, you will also receive a voucher that enables you to download a 1 month free trial of the pro version of our custom-developed motion analysis software along with a tutorial on the technicalities of how to use it. Additionally, we will also provide you with templates and tutorials to use with the app which will make the analysis process faster.

Note: The Binary App 1 month voucher is valid for 1000 days so feel free to purchase and only redeem it when needed.

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.

About Guest

Damian Harper MSc, CSci, ASCC, FHEA

Damian Harper is an academic, practitioner and consultant in human sports performance. He is internationally recognised for the impact his research has had on contemporary sports performance practices. Damian’s current research is focused on the importance of deceleration for health and performance. He has published numerous articles in this area, and developed some of the first evidence-based approaches that can be used to assess, monitor and train an athlete’s deceleration capabilities. 

Damian has consulted with major international sports organisations around the assessment and implementation of training systems for deceleration – this has included the development of the ‘braking strength’ framework for the English Football Association. Damian is also well known for his research in reactive strength and the development of the 10 to 5 repeated jump test – a test protocol that is used world-wide by practitioners, and also built into well-known performance assessment software such as ForceDecks and trainwithPUSH.

Damian is a professional accredited member of the British Association of Sport and Exercise Sciences (BASES) and UK Strength and Conditioning Association (UKSCA). He has extensive experience of working in the provision of sport science and strength and conditioning support across a variety of sports. Currently, Damian occupies external roles leading the development of physical performance for elite girls football as part of the England Talent pathway. 

His Philosophy

Damian’s training philosophy is centred on ensuring athletes have the relevant resources to meet the demands of activities that pose the greatest threat to an athletes health during sports competition. This philosophy to training is developed on the belief the most detrimental impact on motor control and skill is tissue damage or a threat to tissue damage. Therefore, increasing athletes resilience to meet these high-risk challenges can help to ensure co-ordination, efficiency and technical skill is fully exploited during sports competition.

Workshop Information

The workshop will take 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.
Book the
  • Workshop on the fundamentals of acceleration development
  • One month complimentary access to the Pro Version of the app (Note: a discounted workshop only option can also be purchased here)
  • Tutorial on using the app
  • Speedworks templates for the app
