International Sports Performance and Rehab Institute ISPRI is an organization, founded in 2014 by colleagues Koen Marx, Etienne Verstegen, Ivo Tiemessen and myself. It represents an international group of performance trainers, sport exercise scientists, strength and conditioning coaches, sport physical therapists and recovery specialists, working with elite level sport teams and athletes around the world.

The members of the ISPRI group are regarded as key opinion leaders in their profession based on their many years of experience. They work in their own training centers and/or private practices and are travelling world-wide building and maintaining strong relations with sports clubs, federations and educational organizations.

Their expertise is covering all aspects of performance training, rehabilitation, performance recovery and youth development, with a primary focus on musculoskeletal injury prevention based upon the well-known kinetic chain principles. Utilizing the ISPRI methodology and principles, ISPRI pays special attention to the talented youth athlete; by creating an optimal platform to fulfill their potential.

All colleagues share a huge passion for their profession on a daily basis and aim to cover all sports and disciplines without exception.

ISPRI continuously searches for an optimal balance to carry out the values of ‘Evidence Based Practice’; ‘the integration of clinical expertise combined with the best available research in favor of the athlete’s values and expectations.
