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

Photos of Video Cameras

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

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.

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.
