Nike’s Sense Technology

In November 2011, Nike and TOSH (The Orthopedic Specialty Hospital) partnered together to launch the SPARQ Sensory Performance (SSP) training system which consists of an integrated approach to help athletes improve their sensory skills and “see and feel” their particular sport better. This program is being conducted at TOSH’s campus in Murray, Utah. The Sparq Sensory Performance is comprised of technologies, products, and programs that take athletes through a process of assessing and analyzing and then creating steps to improve their visual and sensory skills. Accoring to Paul Winsper, SPARQ Performance Director, "Sensory training is at the cornerstone of how we can build better athletes." Below is a video providing an overview of the training system and its importance to an athlete’s development:

As mentioned above the first two steps in the training system are assessment and analysis. In the assessment phase, athletes use the Nike SPARQ Sensory Station, an interactive touch screen device, and are taken through 10 visual and sensory performance skills that are commonly used in sports. The sensory station collects data on athletes as they go through the assessment. This data is then analyzed and compared to other athletes in the same sport, position and skill level to develop an individually tailored training program that improves their sensory skills.

The third step in the system is the actual training program. Nike uses two innovative products, the Nike SPARQ Sensory Training Station and the Nike SPARQ Vapor Strobe Eyewear, to assist athletes. The Nike SPARQ Sensory Training Station provides software-based training modules that consist of different colored flashing graphics displayed on large touch screen monitors. Certain exercises, which measure depth perception, reaction time, anticipation timing, pattern recognition, focus, etc., require athletes to touch the green flashing graphics while avoiding the red ones. The Nike SPARQ Vapor Strobe Eyewear is a key product to help athletes improve their visual skills. The eyewear uses a strobe (hence the name) or flicker effect to partially block and disrupt an athletes’ vision similar to the opening and closing of window blinds. This strobe effect forces athletes to develop increased focus and quicker reaction times during activity and trains the brain to anticipate what is coming even when their vision is blocked. The speed of the strobe can be adjusted to increase the training level.

  

The Nike SPARQ Eyewear retails at $300.00 and both the Nike SPARQ Sensory Station and the Nike SPARQ Sensory Training Station are available through the Nike SPARQ Sensory Training Help Desk (NSSTsupport@nike.com).

So, is this system effective? According to Nike, training with the Nike SPARQ Vapor Strobe Eyewear overall improved: ability to pick up subtle motion cues, visual information processing, and timing of motion.1,2   Duke University published a study funded by Nike on October 28, 2011 and found varying results. Researchers tested 157 people, 85 participated in lab exercises using the SPARQ Sensory Training Station and 72 participated in different drills using the SPARQ Vapor Strobe Eyewear. Athletes saw the greatest benefits of the training to their central visual field of motion and transient attention abilities. However, there was no measurable benefit to the athlete’s peripheral vision. So for professional athletes, where even the slightest improvement in visual or physical performance can help them gain an advantage over their competitors, this training is worth it, but not so much for the average amateur. 3

Conducting drills to improve an athlete’s senses is just as important as physical training; however most athletes don’t conduct formal training regimens to build their senses in the same matter as their bodies. With the introduction of the SPARQ Sensory Performance training system, Nike will make this aspect of training a priority. It will be interesting to see the next innovation introduced to improve an athlete’s performance.

Under Armour’s E39 Performance Shirt

Julio Jones: UA E39 Video

Under Armour has introduced a new performance shirt, called the E39 ("E" is for electric), that I think gets athletes looking as close to a real life “Ironman” as possible. This shirt features a removable sensor device, called a "bug", just below the sternum area, to monitor an athlete’s physiological changes, including heart and breathing rates and accelerometry data, during workouts.
The "bug" holds a triaxial accelerometer, which measures acceleration and change of direction, a processor and can hold 2 GB of data. Under Armour partnered with a company called Zephyr Technology, a data software company based in Annapolis, Maryland, to integrate the "bug" technology into their shirt. The data collected by the device can be transferred via Bluetooth to mobile devices and laptops for analysis by scouts, trainers, coaches and anyone else interested in a player’s level of performance. Information from the triaxial accelerometer, for example, can be used to improve a player’s acceleration during short sprints or when changing directions quickly. During the combine, this data helped a coach improve a highly touted running back’s speed when running 20 yard sprints. The data collected revealed that the player was decelerating between 10 and 20 yards when he was taking his longest strides. The coach suggested he shorten his strides and he was able to continue accelerating through the full 20 yards.1,2

The technology provided by Zephyr has been used previously to monitor vital signs of the U.S. Special Forces during activity and was thus ideal to use at the NFL combine to show how this technology could be useful for athletes.3  Zephyr created their PSM Training System, which consists of the BioHarnessTM BT, a belt-like device worn around the midsection that captures and transmits physiological data via Bluetooth®, and their OmniSense Software, which is software that can be installed on laptops, tablets, or smartphones and provides graphical representations of the data collected by the BioHarness. The software can provide real time monitoring of up to 64 BioHarnesses simultaneously.4

See a video below from the E39 creators that discusses the product and their goals behind designing the most innovative way to date to evaluate an athlete’s performance in real time:

A Look Inside the UA E39

The E39 is an interesting concept and again shows how technology is being integrated with sports to further improve an athlete’s performance. It is similar to the miCoach technology being offered by Adidas in that the data is captured while a player is working out and can be transmitted via Bluetooth to mobile devices or laptops for monitoring, but the E39 technology focuses more on the biometric changes of an athlete whereas the miCoach technology focuses more on the physical movements the athlete makes. Also the miCoach technology is now available to the general public, whereas the E39 shirt is currently only available to athletes and schools that have contracts with Under Armour, trainers that work with the company, and football teams that want to test the shirt. When the E39 will be available for the general public is to be determined.

The TANGO 12 - UEFA's Euro 2012 Official Match Ball

First post of 2012!


Since Euro 2012 begins in June, I thought it fitting to discuss the official match ball that will be used for the tournament. On the day of the Euro 2012 finals draw, Adidas the official supplier for the tournament, unveiled the TANGO 12 ball, which was created based on the classic Tango balls used in the FIFA World Cup and Euro tournaments of the 1980s but also incorporates a more modern design from the Jabulani ball used in the 2010 FIFA World Cup.

The outside of the TANGO 12 ball is constructed of 32 triangular panels that are thermally bonded together (for those familiar with soccer balls, the panels can be bonded or stitched together) and a protruding micro surface texture was applied. The result is a ball that provides a true, stable flight path and better ball control. The inside of the ball contains a woven carcass and a new bladder that holds air longer and reduces water absorption so playing in the rain won’t affect it much.1,2


After the ball was designed, it went through rigorous quantitative and qualitative testing to meet Adidas’ standards of approval (which exceed FIFA approved standards). According to the Adidas group blog article about the TANGO 12 ball, it is tested for all kinds of aspects including the roundness of the ball, its weight, and even accuracy. The way they test accuracy is actually quite cool.

At Adidas’ test centre in Herzogenaurach, they have a robotic leg with a high-speed camera attached that kicks the ball repeatedly at a goal from 22 meters away. The robotic leg ensures that the ball is kicked the same way every time and is an accurate way to analyze the ball’s performance, accuracy and flight characteristics from a variety of different shots.  Based on these specific tests, the TANGO 12 always hit its intended target with a maximal deviation of 20cm. This means the ball is very accurate and players should hit their target, assuming they are striking the ball correctly.  These types of tests make up the quantitative testing. The qualitative testing consists of letting players, both professional and amateur, use the ball and getting feedback about their impressions and how comfortable they are with it. Initial feedback has been positive.3

Adidas said the same thing about the Jabulani ball which got lots of complaints from players in the 2010 World Cup, so I will take this initial feedback (which usually comes from players that endorse their apparel and equipment) with a grain of salt until its gets widespread use from the general public.

Checkout the video below which provides more details about the ball’s design:


If anyone has gotten a chance to use the new TANGO 12, leave a comment and let me know what you think of the ball.
