With so many energy drinks out there containing caffeine it is a bit of a jungle to give advice to athletes and coaches and/or educate everyone about different options.
This Caffeine Poster was developed by Randy Krum and it is available on his great blog coolinfographics.
I think this is just another great example of how to present data in a meaningful way. Well done Randy!
>I was looking for some freeware or open source software for some biomechanical analysis and came across two software solutions developed by video4coach.
The two solutions are quite interesting and very good quality. The first software is called Skill Capture
SkillCapture is designed to capture video clips which can be directly associated with the athlete also by means of a radio frequency ID system (skillchip).
Video capture can be started by:
- Motion detection
- SkillChip registration
- SkillChip registration and Motion detection.
- Pressing keyboard shortcut
- Using wireless presenter
After video capture it can be automatically displayed for coach interaction directly with the athlete. With the video playback its possible to:
- Adjust playback speed (0.5 – 2.0 of normal speed)
- Rate performace
- Mark for upload
- Draw angle to show body positions
- Freehand drawing
SkillCapture will automatically compress the video to improve storage and improve faster upload to external servers.
The other solution is SkillSpector.
SkillSpector is a video based motion and skill analysis tool for Windows. SkillSpector is freeware and can be downloaded and installed on any computer.
- Video overlay for direct video on video comparison
- 2D and 3D analysis
- Standard model definitions for fast analysis
- Semi-automatic digitizing using image processing techniques
- Easy advanced analysis of linear and angular kinematic data
- Calculation on inertia
- 3D representation of movement
- Simple video calibration
So, two software packages completely free which I am sure can be of help for many sports scientists in the field not able to access the expensive professional software solutions currently available on the market.
I have just installed the software and I will write something more about them after I get the chance to experiment with them a bit more.
I was inspired by this blog post from DAVID MCCANDLESS & STEFANIE POSAVEC reporting their winning design for Wired US in December 2010.
Their task was to redesign a typical medical report: blood tests. All over the World blood tests are returned to a patient in the following way;
Scores are referred to normality ranges and the report is written most of the time in away that is difficult to comprehend unless you are medical practitioner. Furthermore, abbreviations and acronyms are not explained and actions to change the results are not explained.
Then they designed a new report which looks like this:
I would like to comment that not only they have done a great job in terms of design. They have done a wonderful job in terms of how they present the information.
Reports to athletes and coaches should also be like the one above. Simple, color-coded and user friendly as well as providing suggestions for action.
