Shared a sample screenshot of the document. Do we have to factor this before backing a fast bowler?

Conclusion From the above result and discussion, following conclusions can be drawn:

'

1. There is a significant positive effect of limb length on peak bowling speed in Cricket.

 

2. There is a significant positive effect of arm strength on peak bowling speed in Cricket.

those are reasonable claims. but quality of journal appears suspect.

I would say hip flexibility, ability to brace your front foot and back strength matters more.

I read the whole paper - took 10 min. It is a simple correlation analysis. Nothing wrong with that, but it is just a good starting point for formulating a hypothesis, not a conclusion. It does not address any confounding variables/other possible causes (as @Kron mentioned above). Most importantly, the sample size is really small (n=12) and only one of the correlation can be considered "significant" (.73 or so). The other one is like 0.56, which is barely a correlation. Interesting, but a few grains of salt would be in order here. Hopefully, they don't use this too stringently and eliminate kids who might otherwise be talented.

 

A reasonable hypothesis does not a conclusion make.

depends on the action. If you got a slinging action, where most of your torque is generated by your upper back, then length of the lever, aka arm becomes decisive for generating higher angular momentum, thus higher release speeds.
