Do you know about a scientific study on the power of the boxers from the past? Is there a scientific way to compare the power of the old boxers to the modern ones? For example, can we actually calculate the punching power of Marciano by watching how he was punching the heavy bag if we know the weight of the bag and observe its moving and trembling? Can we calculate the actual speed of the punches that Joe Louis, Ali, Marciano and other old boxers showed by analyzing the video clips and compare them to the speed of Usyk, Joshua, Wilder and Fury or Tyson, Holyfield and Lenox Lewis? Is it possible to have a true measurement of the speed and the power of the boxers based on the video clips?
