Measuring a 50 m sprint time \nhas been used for a long time as a teaching material to promote scientific and mathematical thinking, \nbut the problem is that the stopwatch has a large error margin. The standard frame rate for video \nrecording in schools is 30 or 60 frames per second, which is significantly less accurate than the \n1,000 frames per second used in official track and field records. Based on this background, this study \nexamined the magnitude of error when 50 m sprint interval times were measured using video images \nwith standard frame rates. Four university students enrolled in a health and physical education course \nparticipated in this study. A photoelectric sensor, 59.94 fps video image, 29.97 fps video image, and \na stopwatch were used for measurement instruments, and a person with a stopwatch and another \nperson operating video cameras were set 15 m and 30 m from the goal line. The measurement error \nof interval times (each ten meter) was analyzed using 40 total runs, assuming the measurement by the \nphotoelectric sensor as the true value. As the result, the following were revealed. \n 1) Errors were smaller with the stopwatch, 29.97 fps video images, and 59.94 fps video images, in \nthat order. However, the difference between 29.97 fps and 59.94 fps was less than 1/100th of a second. \n2) The error was smaller at 30 m than at 15 m between the video camera and goal line. 3) At the 10 m \ninterval and further, the average error of stopwatch was 0.048 seconds, and the largest error was 0.230 \nseconds. On the other hand, the measurement error of the 59.94 fps video image was 0.018 seconds on \naverage and 0.064 seconds at the largest. \n These results suggest that by placing video cameras as far away from the finish line as possible and \nusing high frame rate video shooting, the measurement of interval times can be used as a teaching \nmaterial for STEAM in physical education.
