Biomechanics of Olympic Athletes in 1900
At the 1900 Olympic Games in Paris there were scientific investigations performed on athletes. In addition to anthropometric measurements of athletes, some athletes were also photographed performing their sports as well as some analysis of performance such as in rowing.
Etienne Jules Marey, a pioneer of chronophotography and biomechanics captured images of some of the competitors at the 1900 Olympic Games. Chronophotography is a photographic technique which captures movement over several frames, which can be subsequently arranged like an animation, enabling analysis of the athletes' movements. Such techniques are similar to today's biomechanical analysis of sporting technique using video.
Here is an example of the world record holder American Michael Sweeney showing his high jump technique (starting from top right position).
One interesting finding from Marey's analysis was the comparison of America's Alvin Kraenzlein's winning hurdling action to the method of Frenchman Mr Pontié. In this example, the photographic images taken using chronophotography where drawn onto a single image, clearly showing the progression of the technique. The drawing below shows Kraenzlein taking the hurdle with a straight front leg, similar to the modern hurdler, compared to the Frenchman below.
Rowing mechanics was studied by Dr. Lefeuvre using instruments attached to the boats. The study was designed to determine the qualities of the winning teams, by relating race times to the movements of the boat and the rower.
The figure below shows the boat speed increasing from the start up to maximum speed (taking about 20 seconds), the dotted line indicating the average speed of the boat. Each of the large oscillations of the speed curve corresponds to a full stroke of rowing.You can compare the shape of the stroke curve to the one below, showing a different shape of the curve with the use of a different rowing technique.
