Dr Enora Le Flao (Postdoctoral Scholar, The Ohio State University) ,Dr Lizzy Williams (Senior Lecturer, Sport and Exercise Sciences, Swansea University) and David Powell (PhD student, Swansea University) discuss concussions in Rugby Union and instrumented mouth-guards, which have embedded sensors to measure linear and angular kinematics of the head. Time Stamps: 0:00-4:20 Intros 4:20-5:09 What is the rationale behind all this? 5:09-11:23 How has this been previously done and where are we now? 11:23-12:59 Is the mouthguard a replacement for visual monitoring – medical threshold? 12:59-14:44 False positives and negatives 14:44-17:59 What causes concussion? 17:59-22:58 How do the mouth guards work? What are they monitoring? 22:58-26:17 Training and workload 26:17-30:25 Sex differences 30:25-32:03 Misconceptions and eventual aims 32:03-40:00 Further research 40:00-42:52 Other sports 42:53-46:20 Further information 46:20-47:28 Outro and goodbyes
