Discus Throwing Analysis Using Video Viewing Option
Video View--The video viewing function permits the biomechanist to observe a sport or functional movement from multiple perspectives, simultaneously. This allows the coach or clinical to perform sport or clinical evaluations at sampling rates that may be 2-10 times faster than visual observations depending on the video cameras transport rate.

Gymnastics Techniques Comparison of Backhand Spring & Flic-Flac Using Synchronized Views
Sync View--The synchronization function provides the capability of performing a comparative study of two separate trials or different movement techniques in a side – by- side analysis format.

Baseball Pitching Analysis Using Integrated ViewingIntegrated View--The viewing option permits the user to examine the kinematic / kinetic data of the human movement simultaneously with the data point trajectory and the corresponding video frame from multiple cameras). This feature of creating dynamic outputs may be used in performing simultaneously qualitative and quantitative analyses for sport performance.

High Jump Analysis Using Integrated Data OptionData View -- The data view is capable of showing many different kinds of numerical data parameters, such as, displacement, velocity, force, EMG and so on. Each channel loaded can be manipulated numerically in order to normalize and modify the data. Each individual data channel can utilize a unique color and a label can be added. The data view can present the data in three different formats, namely, line graphs, bar graphs and numerical table values.

The Future• A user records and stores Video file in a specific folder on
his or her hard disk• A central directory maintained by ISBS.com keeps track of
which users are logged on, cataloging by title and researcher/biomechanist the activity in each user’s special folder
• A user searches through the ISBS.com directory for a desired activity or sports. Once the activity is downloaded it can be used for further analysis or observation. This file can also be sent to another person as e-mail or attachment
• Any user folder can be shared with the rest of the World• ISBS.com monitor and publish the catalogue of activities
and sports world wide
