1 Improving Interdisciplinary Education of Anatomy, Biomechanics and Practical Sports using Non-Profit Software

2 Interdeciplinary Sports Biomechanics Anatomy

3 How to improve interdeciplinary? Examples in biomechanics not enough Examples in anatomy not enough Examples and language in sports not clear enough Needed exercises during sports to emphasise biomechanics and anatomy theory Software interesting alternative but often very expensive Could Open source solve our problems? SkillCapture, SkillSpector, Kinovea

4 Gymnastics at SDU Practical skills Handstand, cartwheel, front handspring, standing back somersault, running punch front tuck using mini trampoline Video feedback Video based movement analysis 2 Case assignments with focus on biomechanics and anatomy. Using problem based learning (PBL) Parkour and video filming Safety spotting course

6 Lecture plan -Gymnastics Modul 2: Kropsbasis Basis, tillid, tryghed, bevægelsessansning, kropsspænding og lege. Balancer, håndstand, grundpositioner, kropsskema og kropsbillede. Modul 3: Video + Introduktion til tilløb & afsæt i afsætsredskab. Videotilvænning: SkillCapture & SkillSpector Tilvending til afsætsredskab -> opspring. Springfaser; afsæt, svæv, landing. Modul 4: Forlæns salto med tilløb (evt. valgfrit afsætsredskab) Modul 5: Case 1 Running, punch somersault - Descriptive Modul 6: Forlæns spring gennem håndstand: Mølle-rondat, Kraftspring Modul 7: Spring over redskab Hovedspring og strakt overslag Modul 8 & 9: Baglæns spring Flikflak, Baglæns salto. Modul 10: Case 2 Rotation - Optimization Modul 11: Modtagning & repetition Modul 12/13: Parkour Springmiljøer og redskabsgymnastikkens horisontale plan. Filmproduktion (Parkour) Et eksempel på det fremvisende element.

7 Terminology Communication is one of the most important tools when improving students performance Use standard gymnastics vocabulary Use biomechanical terminology to improve the connection between the theory and practical Muscle names and joint movement to link to anatomy Example: Student is not capable of completing the back tuck somersault. The gymnastics correction would be to improve the tuck position but we need the student to improve inertia!

8 Video feedback Extensive use of video Problem Based Learning Improve student performance Wall mount computer with touch screen and surveillance camera Students own computer

9 Why video? Maurice Merleau Ponty - Phenomenology Body Image How we perceive movement and skills that we do Body Schema How the movement

10 Case 1 -Descriptive Video filming of running punch front somersault in mini trampoline Kinematic analysis using SkillSpector Analysis of the following data: Running velocity, linear momentum Angular momentum Angle of takeoff, velocity of takeoff Height of centre of gravity during somersault Time in trampoline Hurdle step length and so on. Movement analysis focus on muscle groups involved

11 Case 2 -Optimization Video filming of running punch single front somersault Kinematic analysis using SkillSpector Optimization to perform double somersault Inertia Trajectory height (time) Takeoff velocity and angle Consideration of running speed and the utilization of mini trampoline

12 SkillCapture Video capture and feedback in slow motion and frame by frame User profiles to sort video clips Upload to different locations (internal server, youtube) Simple user interface

13 SkillSpector Video based kinematic analysis Human model 2D and 3D analysis Video overlay

14 Kinovea Video capture and delay Qualitative movement analysis Dartfish like interface
