Tennis court
- Gavin MacMillan, Chief Executive Officer, Sport Science Lab, USA
🎾 Mental or Mechanics? Unlocking Tennis Performance with Biomechanics!
Join Gavin MacMillan as he delivers his keynote address:
🔹 Part 1 – Biomechanics: Key to Success 🚀
Master the mechanics of the tennis serve—from power generation to injury prevention.
🔹 Part 2 – Biomechanics: Key to Success 🎯
Break down the mechanics of ground strokes and explore how optimising techniques can enhance efficiency and power.
Coaches and researchers alike will discover how to bridge the gap between science and skill, and most importantly—how to convince athletes to change their mechanics for long-term success.

The Power of Planned Disruptions
Friday 4 April, 12:00-12:30
Tennis court
- Ruben de Bruin, Coordinator Mental Training, KNLTB
A planned disruption is a training method designed to teach athletes how to perform under pressure by intentionally creating stress during practice sessions. This approach trains athletes to cope with stress while executing skills and making decisions. In this presentation, Ruben will demonstrate how to apply safe and effective planned disruptions in tennis.

Planning for Peak Performance
Friday 4 April, 13:30-14:30
Tennis court
- Matt Little, Strength and Conditioning Coach, UK (TBC)

Physiology Insights
for Tennis Succes
Friday 4 April, 14:30-15:00
Tennis court
- Glenn Bjorklund, Associate Professor, Dept of Health SCiences, Mid Sweden University

Stroke Booster
Friday April 4, 15:30-15:50
Tennis court
- Natasja van der Boon, Embedded Scientist, KNLTB
Natasja will demonstrate the importance of using the kinetic chain effectively in sports to achieve optimal ball speeds. She will be showcasing the Tennis Stroke Booster, a tool that visualises the kinetic chain during fast-paced tennis serves, often completed in just 0.3 s. Learn how this technology can help improve performance and minimise the risk of overuse injuries.

Mastering Agility
on the Tennis Court
Friday April 4, 16:15-17:00
Tennis court
- Miguel Janssen, Federation Strength & Conditioning Coach, KNLTB
- Marleen Jansen, Embedded Scientist, KNLTB
Agility is a key skill for tennis players, enabling them to execute quick, multidirectional movements in response to the ball and their opponent’s positioning. Assessing agility is essential for enhancing performance and guiding players’ development. In this session, we will demonstrate how we monitor agility performance to pinpoint areas for improvement, and outline the specific agility training strategies that follow.
