Does anyone know if the official method for measurement of reaction time
for a 100 m dash uses force of at least 98 N on one or both of the blocks
as the stop signal for the timer? This method was quoted in a 1999
article as being official, but as things change one never knows if this is
still the case. Also, are there companies that sell such a reaction time
device?
