Joining calls for free sports facilities either side of next year's Games, the academics have called into question what legacy the event will deliver for some of the UK's most deprived communities.
Dr John Kelly, a sports sociologist at Edinburgh University, said evidence of a legacy of increased sports activity from previous Olympics and Commonwealth Games was thin on the ground, adding that regular mentions of positive spin-offs helped justify the outlay to the taxpayer.
Meanwhile, Dr Joe Bradley, senior lecturer at Stirling University, said legacy had to be "beyond the soundbites and looking to see what individuals and organisations can make financially".
The city council, which has the responsibility for legacy, said the Games were a "priceless opportunity for Glasgow", which was already delivering benefits through thousands of jobs, apprenticeships and training places, new and improved venues and infrastructure.
The comments follow calls from experts for sports facilities to be free of charge around the Games amid concerns 2014 risks bypassing tens of thousands of people from deprived communities.
Sports development specialists, youth workers and politicians said games organisers are overly focusing on middle-class young achievers, particularly in the context of a hike in entrance fees to municipal sports facilities of 5% between now and the Games. The trust charged with increasing sport participation in Glasgow disputes the claims, pointing to a rise in the use of facilities and a surge in membership of sports clubs
Dr Kelly said most of those who championed legacy were officials and athletes who rely on funded Games for their own goals, "despite a dearth of hard evidence to support such proclamations".
He added: "In a city with a third of households out of work, one wonders how many people from these homes will be making use of a bike velodrome."
Dr Bradley, who also works with grassroots sports in a deprived area in the west of Scotland, added: "Ethnicity, class, poverty, health, community sustenance and building, widespread health benefits and social capital have to drive the question of legacy. Issues around these are what will make the games a success in the eyes of most people."
A council spokesman said the city had learned from mistakes by other hosts, with plans to ensure Glasgow will be better off economically, environmentally and socially post-Games. He added: "The council has granted legacy status to over 250 projects and organisations that have been inspired by the Games to develop activities and programmes that are making a real difference."
