Congratulations to Dr @MindcraftPerf who passed his DProf in Elite Performance VIVA today 👨🎓 His thesis investigated ‘the assessment & development of psychosocial skills in male English academy soccer’ @Uni_Lancashire Thanks to examiners @YiannakiChris & Andrew Cruickshank

New research paper Relationship between reactive strength and sprint acceleration performance and kinematics 🔸24 field sport athletes 🔸RSI & CT via 10-5 RJT 🔸30m speed test (5/10/20/30m splits) 🔸Stride length & frequency 🔸Sprint-CT 🔸Velocity / step
Such a key skill to train and a key area in injury rehab - particularly with pre-season about to start. Can’t decelerate? Then you can’t change direction… 💥
