''Modern cricket itineraries are the root cause of players becoming burnt out and consequently several key performers are suffering from serious injuries,'' Woolmer wrote in his column for The Times.
The Pakistan coach said more than the number it was the frequency of matches which was the cause of concern as players were not getting the time to recharge themselves owing to back-to-back games.
''It is not so much the amount of cricket they are asked to play as the fact that one Test match is following hard on one that has just finished. Itineraries are congested and it is the players (and the spectators), not the bookkeepers, who suffer. This is a problem that has to be addressed sooner rather than later,'' he added.
Woolmer, who is here with the Pakistan team for a two-month-long tour, said the practice of having ODI series after the conclusion of long Test series was adding to the physical pressure on cricketers who will find it hard to cope.
''In conjunction with back-to-back Test matches, a five-match series of one-day internationals piles added pressure on to the players,'' he added.
Speaking about the recent introduction of Twenty20 cricket in the domestic circuit of many Test playing nations, the Pakistan coach said though he was not a big fan of the format, he was not opposed to it but felt its expansion at the international level should be limited.
''While I am not a great fan of Twenty20, chiefly because I am steeped in the traditions of five-day Test cricket, I understand the need for such domestic competitions. Inevitably, this will be a part of the international calendar, but it should be played sparingly at this level to ensure the prime forms of the game remain sacrosanct,'' he said.
