Context: Twenty20 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.


Question: Using the passage, please give some critical impacts that Twenty20 format had on the game of cricket?

Twenty20 cricket is a shortened game format of cricket. Regardless of a player's role on the team, Twenty20 had "raised the bar" in terms of fitness standards for all players by requiring better levels of strength, speed, agility, and reaction time.

Although numerous important commentators, including Adam Gilchrist, have praised the Twenty20 format as a better, faster, and more financially feasible manner of promoting the game of cricket around the world, the format has been criticized by other famous cricketers. Some of the impacts of this format on the game of cricket are: 

1. Former Australian captain Ricky Ponting has blamed Twenty20 cricket for harming Test cricket and impairing batsmen's scoring skills and concentration.
2. Former Australian captain Greg Chappell had similar concerns, saying that young players might play too much T20 and not fully develop their batting skills.
3. Former England player feared that bowlers playing only Twenty20 format many not develop bowling skills fully.
4. Former West Indies captains Clive Lloyd, Michael Holding, and Garfield Sobers criticized Twenty20 for its role in discouraging players from playing for their country's test cricket team and instead play in a Twenty20 franchise cricket elsewhere in the world to make more money.

In summary, Twenty20 format had both positive and negative effects on the overall game of cricket.
