Kaleigh Herring Dr. Ladores - EDUC 635 March 26th 2012 Special Gadget ReportVideo Cameras – Biomechanical Analysis
Video Cameras • A video camera or camcorder is an electronic device that captures video and audio to be played back by the same device. • This gadget was originally designed for television broadcast but has become an everyday handheld device. • Large, mounted, required wiring and audio recording from separate room • Detachable cameras and out of studio recording • Use of cassettes (no more wires) • Digital Camcorders (HD/tapeless/memory cards) • 3D HD camcorders • Cell phones/digital cameras/laptops
Use of Video Cameras in Exercise • Biomechanical Analysis of athletic movements: • Swing of a bat • Soccer free kick • Golf Swing • Dismount of a gymnast on a balance beam • Pivoting motion in most athletics • Correcting/Evaluation of athlete’s form during lifting • Creating educational videos on various exercise programs: • Strength training • Yoga • Stretching • Conditioning drills • Plyometrics • Recording of a game
Research in the Field • Use of Journals • Journal of Sports Medicine • Journal of Kinesiology • Journal of Exercise and Sport Science • Journal of Biomechanics • Research Studies/Experiments • YouTube Videos • Experience of fellow Colleagues
Research Examples • http://www.findphysio.com/E-books/Biomechanical%20Evaluation%20of%20Movement%20in%20Sport%20and%20Exercise.pdf (Chapter 2, pg.8; discussion on how video is used to to do motion analysis) • http://legacy.kines.umich.edu/faculty/full-time/journals/mg/Gross_98.pdf (Analysis of Human Movement Using Video; this study was done to help students understand the fundamental skills (body movements) needed in Kinesiology through the use of video) • http://sports-motion.com/support-camera-requirements.htm (this link recommends why certain video cameras are better than others to use when analyzing sport specific movements) • http://www.youtube.com/watch?v=aJjv8tWbj4c (this is a video of a very general biomechanical analysis of a soccer free kick; the yellow dots and lines are what we would look at and elaborate on when breaking down the video)
Use in the Classroom • My gadget is going to be used as an end of the semester project. The student will be given the knowledge of the human anatomy and biomechanics of the upper and lower extremity throughout the semester. They will possess the background knowledge needed to do an analysis, they will just need the knowledge of the gadget • Students will be given a powerpoint presentation (background info of video cameras/uses of/examples in the field) • Students will be given the assignment and explanation (project procedures/goals/format of report) • Students will draw numbers and choose body movement they will analyze (ex. soccer kick/football punt/golf swing) • Students will use the video camera to tape each other doing movement (two different views) • Students will then be given the video of themselves through email • Students will breakdown the movement (biomechanical analysis) through use of the format given to them previously • ASSESSMENT: Students will present their findings (use of their video clips/projector/written report)
Example #1 This is an example of the students using the video camera to record each other doing the activity in which they will then evaluate. Lateral View
Example #2 This is an example of the students using the video camera to record each other doing the activity in which they will then evaluate. Posterior View
Reflection • After being both a student who did this task and a teacher who has had student do this, I found that this gadget is very easy to use. Many students enjoy the chance to be able to use the video camera to do a presentation. • Outside of it being enjoyable and easy to use, in order to do the task we are asking of the student, the play back of the video is a necessity. • Through the use of the video playback students are able rewind/fast forward/slow down/freeze frame, which help to assist in their breakdown of the biomechanics of their chosen activity. • Emailing the videos to students was simple following everyone doing the body movement of their choice.
