I am not seeking to use this thread to re-contest the issue of whether bowling really is getting slower. Apart from everything else, I'd rather take a skilled 154K bowler like Lillee over a 160K Thomson every time.
No, this thread is to consider whether other factors have influenced changes in bowling speed.
1. Factors which might have increased speed
- improved nutrition
- improved training regimens
- greater professionalism since around the early 1950s.
- increases in human size
- a massive reduction in the amount of First Class bowling undertaken by any players
2. Factors which might have reduced speed
- improved nutrition leading to excessive bulk
- maladaptive training regimes, e.g the focus on Rugby League sized bodies which damaged Craig McDermott and ruined Ryan Harris' career.
- reduced ability to use anabolic steroids.
- the end of rest days in Test cricket, since which time fast bowlers have suffered far more injuries.
- T20 cricket introduced a need for variation, and fast bowlers now have less repeatable actions because repetition is no longer viewed as good. The less repeatable the action, the more injuries that follow.
- international cricketers also spend less time in the domestic First Class game, which probably also makes for less repetition and repeatability.
