The visit has been worth it. On television, weightlifting appears to be too much of a workmanlike category. Powder your hand, grab a bar weighted with discs more than twice you weight, or the equivalent of so many refrigerators, hold it overhead till your arms are properly extended, and then drop it making sure your feet are not in the way.

The sound effects provided by the crowd show how false and simplistic that is. As a weightlifter picks up the bar and squats, the roar begins, picking up strength as he then stretches his legs, the sound somehow managing to convey that it is the legs that really do the carrying, more than the arms and shoulders. In fact too much arm just gets in the way. It’s an aspect sport historians, like the much quoted David Wallechinsky, amply highlight with photographs of Joe De Pietro. The 4 ft, 10 inches tall American, who won the first gold in this category (London 1948), had arms so short that they would have taken the bar just inches above his head.

But weightlifting is a sport of many oddities. To qualify to compete in the Olympics — besides in the wildcard categories — it’s not your individual performance that matters, but your national team’s. Depending on the team ranking in the world, a country gets in a certain number of competitors.

Weightlifting’s not quite rocket science, but the trip to the aeronautics campus has been informative. After all, that’s what the Olympics are about too. To alert us that to observe is to learn.
