cricket is claimed to have resulted in a more athletic and explosive form of cricket. Indian fitness coach Ramji Srinivasan declared in an interview with the Indian fitness website Takath.com that Twenty20 had "raised the bar" in terms of fitness levels for all players, demanding higher levels of strength, speed, agility and reaction time from all players regardless of role in the team. Matthew Hayden credited retirement from international cricket with aiding his performance in general and fitness in particular in the Indian Premier League. In June 2009, speaking at the annual Cowdrey Lecture at Lord's, former Australian wicketkeeper Adam Gilchrist pushed for Twenty20 to be made an Olympic sport. "It would," he said, "be difficult to see a better, quicker or cheaper way of spreading the game throughout the world." In a similar vein, several commentators have noted that the T20 format has been embraced by many Associate members of the ICC partly because it is more financially viable to play. Former Australian captain Ricky Ponting, on the other hand, has criticized Twenty20 as being detrimental to Test cricket and for hampering batsmen's scoring skills and concentration. Former Australian captain Greg Chappell made similar complaints, fearing that young players would play too much T20 and not develop their batting skills fully, while former England player Alex Tudor feared the same for bowling skills. Former West Indies captains Clive Lloyd, Michael Holding and Garfield Sobers criticised Twenty20 for its role in discouraging players from representing their test cricket national side, with many West Indies players like Chris Gayle, Sunil Narine and Dwayne Bravo preferring instead to play in a Twenty20 franchise elsewhere in the world and make far more money. Match format and rules Format Twenty20 match format is a form of limited overs cricket in that it involves two teams, each with a single innings. The key feature is that each team bats for a maximum of 20 overs (120 legal balls). The batting team members do not arrive from and depart to traditional dressing rooms, but come and go from a bench (typically a row of chairs) visible in the playing arena, analogous to association football's technical area or a baseball dugout. General rules The Laws of cricket apply to Twenty20, with major exceptions: Each bowler may bowl a maximum of only one-fifth of the total overs per innings. For a full, uninterrupted match, this is four overs.
