These times were recorded and sorted from the smallest to the largest and illustrated on the following graph: This method accurately measures the difference in the coach started time and the fully automated start time without introducing additional variables. The timer was started when the athlete left the start line and stopped when the coach at the 40-yard line pressed the stopwatch button. To measure the difference between the hand time and the FAT, a signal wire was used to connect the stopwatch to an electronic timer. The fully automated timing system was stopped once the athlete crossed the electronic sensor at the 40 yard line as described above. ![]() The hand timed timing system was stopped when the coach pressed the start button.The fully automated timing system was started using the fully automated timing sensor described above.The coach was provided a fully functioning stopwatch that was tethered to the electronic timer, via wire.The following procedure was used to determine how much time it takes a coach to press the start button of the stopwatch: ![]() Additionally, the FAT electronics provided by Zybek Sports are tested and fully traceable to the atomic clock located at the National Institute of Standards and Technology located in Boulder, Colorado. The FAT system used to measure the electronic time was the exact same equipment and process used at the NFL Scouting Combine since 2011 and several other major events: the Rivals/adiZero Camp Series, U.S. WHAT is the difference between hand timing and fully automated timing (F.A.T.) under the best possible testing conditions?Īlthough “best possible testing conditions” is an inherently subjective qualifier, significant efforts were made to use the same process used in the Standardized Athlete Test (SAT®) for the fully automated timing and use an experienced professional coach under ideal weather conditions. To make this data meaningful, we setup the data collection and testing to answer the following question: One possible reason that an objective study has not been completed is the large number of variables that can have a significant effect on the results these variables include weather conditions, time of day, variance between coaches’ focus level, and much more. In this Part 2 post, we look more deeply at the actual difference in these times, and break down how we were able to quantify that difference:Īlthough it is generally acknowledged by professionals that hand-measured times are always “faster” than actual or fully automated times, there have been few disciplined studies conducted to objectively quantify this difference. The average time it takes for a coach to press the start button after the athlete begins to run can also vary dramatically based on the human factors (e.g., coaches’ response time, general health, focus, vision, etc.) and even environmental factors (e.g., moisture, ambient light, etc.). Therefore, the time will always appear to be faster than a fully automated time. Put another way, when using a stopwatch, the athlete will always have a ‘head start’ because the coach starts the time after the athlete starts to run. Fully Automated Timing: the time starts AS the athlete starts to run. Hand timing: the coach presses the start button AFTER the athlete starts to run. In Part 1 of this series, we took a brief look at the differences between stopwatch and fully automated timing, detailing what each procedure entails, and why the resulting times can be far different.
