Several types of tracking technology exist, and the type used depends upon the the circumstances of the competition. In training, some teams are now tracking with systems like RedFIR, a German technology comprised of tiny (15 gram) radio transmitters that can be placed in uniforms, footwear or balls, and a network of receivers set up around the field. The ...

You are right that the French Open is the only Grand Slam tournament without Hawkeye, The reason is that Clay, unlike grass and hardcourts, leaves a mark that players and umpires can check and verify if the ball was in or out. You can argue that some mistakes can be made but that's quite rare, A hawkeye system is very expensive and the cost/benefit ratio ...

The UEFA Champion's League uses goal-line technology. This is an automated system which detects the moment the ball has crossed the goal-line under the crossbar. It sends a signal to the referee via a wrist-mounted alarm unit to show a goal has been scored. This reduces the reliance on precise visual judgements from bad angles. The referee indicated that ...

Endomondo.com works very well importing all the information from Nike+. After that you can use it to export individually to some other services, or use it as I think is pretty good.

KERS stands for Kinetic Energy Recovery System. It's a system similar to those used in many hybrid cars: It recovers the kinetic energy of the vehicle when braking and stores it either mechanically in a flywheel or electrical in a battery or capacitor. This energy is then used later under acceleration. The use of KERS in Formula is limited to an additional ...

Update: Sorry folks for taking so long to get around to this update - I had to retire this tool in 2016 ago due to nike changing their API, and not having enough time to re-engineer the code, so this is no longer an acceptable solution. Original Post: I wrote a tool to help export workouts from nike+ for upload into other tools like Strava or Runkeeper: ...

The watch is the part of Goal Line Technology system, Under IFAB LAW 1 - THE FIELD OF PLAY, GOAL LINE TECHNOLOGY (GLT) The indication of whether a goal has been scored must be immediate and automatically confirmed within one second by the GLT system only to the match officials (via the referee’s watch, by vibration and visual signal).

A lot of professional teams these days use ProZone. This is used for Performance Analysis (which 'distance covered' would probably be included), Physiological Monitoring, Player Recruitment and Research/Consultancy. See here for more details on Player Tracking. Players who wear Adidas boots can also take advantage of the miCoach Speed Cell which covers ...

Trailrunnerx on osx can sync with nike+, including after Nike's recent changes to their API. From there one can export to various file formats. The gpx-tracks has worked for me for uploading to Strava and MapMyRun. Runkeeper on the other hand seemed to have trouble extracting the relevant data from these files. The Smashrun website can sync with nike+ ...

The main benefit for me is in preventing body fluids from pooling in my legs (I have very low blood pressure). This is billed as assisting in recovery post exercise.

Rangefinders can be a valuable tool but to get the greatest benefit it is important to do some homework before setting onto the course. A rangefinder provides accurate distances to objects on the golf course but unless you know how far you hit each club then there is little benefit in having the greater accuracy. To get the most use out of a rangefinder it ...

Note that I've changed this answer several times, to keep up with current status. TLDR: Use Smashrun, then Tapiriik In the previous months/years Nike has been changing the way it provides data; including who it provides it to. I'd been using the exporter by Rhys McCaig for quite some time, but he has since discontinued his tool. I've also tried Tapiriik, ...

Essentially it hasn't been introduced by UEFA because the top brass don't support it because of the financial cost. Platini says: "I prefer to put more money into youth football and infrastructure than spend it on technology when there's a goal in a blue moon that hasn't been seen by a referee." "It would cost around 54 million euros (£46m) over five ...

There are 16 cameras around the field that can track each player's distance traveled within 3% accuracy. Source - WSJ

I strongly suspect that the manufacturers of Hawkeye and similar ball tracking systems would actually prefer not to have a hard 'ground truth' to compare to being beamed live to millions of viewers. These systems are not as accurate as the TV graphics imply and there use as part of the umpiring process is not all to do with accuracy. It is as much about ...

The Android app SyncMyTracks can import and export from and to Nike+, Strava, RunKeeper, Endomondo, Garmin Connect and other services. I've been using it for a few months, and it works great!

http://www.rungap.com/ supports a whole bunch of apps including Runkeeper, Garmin and Nike+. Unfortunately, it's doesn't provide online access. Just smartphone app access. Update: Smashrun can import runs from Nike+ and Garmin directly. It also supports importing gpx/tcx files. I have the free membership for now. It is pretty bare bones, but from the looks ...

Firstly, compression means less work needed by stabilisers to maintain the position. An example is powerlifting. Secondly, it improves the post-recovery particularly in athletes who have very low recovery HR. Thirdly, they are timeless. Different compression clothes originates from nursing and old people care where for example compression stockings are used ...

This is similar to my answer to this question but I felt that it was also appropriate here. Livestrong has a great page that illustrates a lot of points and references medical studies to support it. Some key points: limits extra muscle motion, or "oscillation" ... [which] reduces the amount of energy you are expending assist[s] the hamstrings in ...

This was handled the same way small local swim meets are handled these days: stopwatches. Okay, they may not always have been digital, but having two or three timekeepers per lane allows you to tinge each competitor and remove some of the human error. When it was a really close finish they would have to make a call - who looked like they hit first?

I doubt that this would be public. The Umpire's Association is typically quiet about this kind of thing. They don't want to throw their members under the bus. If they came out this year and said "2012 is better than 2011" but then don't say anything in 2013, it's safe to assume that there was a decline, but the Umpire's Association doesn't want to hurt ...

There's the Nike+ iPod/iPhone app, which according to Nike: Nike+ has 5 million users. There are a number of Nike shoes that contain the requisite sensor/chip, and some third parties, such as Polar, have provided accessories that work with the Nike system.

When I used to swim there was also a place judge and ties were decided by him. In track during the sprints each lane has more than one timer if electronic timing isn't used. For distance events there are usually two timers timing everyone. If there is a tie the head judge decides.

I'm not sure what format the Nike files are, but the Fit File Repair Tool offers the most comprehensive options for conversion from and into the most commonly used formats (fit, tcx, and hrm). On top of that, it lets you fix faulty files, e.g. when the gps or the heart rate monitor went crazy due to interferences. If conversion to tcx is sufficient, I found ...

As there is no official wording from Sky Sports on technology behind Rev Counter there were two possible theories, one would be high-speed camera coupled to a computer running an image recognition/analysis program as mentioned in the Physics StackExchange Question. Which would be challenging in that given time frame.Other one is 3D Doppler Tracking that is ...

Clay courts leave a visible mark which shows where the ball lands. This is the reason why the staff at Roland Garros clear the court often during a match so there wont be overlap of marks(or mistake of the actual mark), which can cause confusion. If a ball is questionable, then the referee will come down and check the mark on the court and make his ...

The (free) online app called Tapiriik provides a great way to sync between many applications. Including endomondo, strave, runkeeper, dropbox, garmin, ride with gps, motivato, and many others.

First, Hawk-Eye technology is not available for every court that professional matches are played on. So, in those cases, players can't challenge a call because no Hawk-Eye is available. The chair umpire will inform players before they begin to warm-up if Hawk-Eye will be in use for their match or not. Second, Hawk-Eye tracks the trajectory of each shot ...
