The ECB fast bowling directives have changed following a two-year consultation process. The outcome is that bowlers up to under-15 level are now able to bowl longer spells and more overs in a day.
Under the new guidelines bowlers at under-16 and under-17 level are now permitted to bowl an extra over per spell, but those in the under-18 and under-19 category have had the total number of overs they can deliver per day reduced from 21 to 18.
These guidelines will come into effect for the start of the 2010 season.
The fast bowling guidelines are designed to raise awareness of the need to nurture and protect young fast bowlers through their formative years. Research has shown that fast bowlers are by far the most likely players to be missing playing and training time due to injury.
