While it may be counterintuitive, the evidence suggests that a lighter ball increases stress on the arm because it allows for faster arm action.
I’ve heard that too, but after discussing it with a couple of orthos and trainers, a lot depends on the weight, so a small reduction in weight and the benefits should more than make up for any additional stress.
Then there’s the argument of faster arm action creating more stress, which I wholeheartedly believe. If that’s true, why in Hell hasn’t there been some kind of action taken to reduce the work of the harder throwers? Because the number of coaches out there who fill out the lineup cards and worship at the altar of winning is so overwhelming.
