Roy Sinclair was a mathematics professor at the University of Alberta who, as a weightlifting fan and official, developed the Sinclair Formula, which is in use in the sport around the world.

Roy Sinclair (large mug)The mathematician’s formula is a statistical method to evaluate the performance of weightlifters of different body mass. A Sinclair Total identifies the athlete who, pound for pound, lifts the most weight. It was adopted by the International Weightlifting Federation in 1979 and is used by the Canadian Weightlifting Federation. The formula is recalculated every four years using new world records, so is never out of date.

Sinclair officiated at the first weightlifting competition in Alberta, held in 1958. He has been an official at most competitions in the province since.

He was one of seven vice-chairmen of the 1978 Commonwealth Games at Edmonton and was the officials coordinator. He served as president of the Alberta Weightlifting Association from 1976-77 and 1985-87.

Sinclair was an official at many national and international competitions.

The emeritus professor was inducted into the Alberta Sports Hall of Fame in 2011.

In 1964, Sinclair used computers to determine the odds of a grand-slam bridge hand after firefighter Phil Sevigny was dealt the ace, king and queen of all suits, as well as the jack of hearts. The professor put the odds at 535 billion to one.

Sinclair became an activist for the cause of Western separatism after attending a Western Canada Concept rally led by the lawyer Doug Christie in 1980.
