I contributed to an article in the current issue of The Ring, known as The Bible of Boxing. What's funny is that the December 2015 issue has been out in the US for some time now. I've been checking in at WH Smith on Fargate for over a week. After a good workout at Ponds Forge this morning, I nipped into WH Smith -- and they finally had it!
Keith Idec is the reporter I worked with. He wrote nice article called "Balance of Power," in which he describes how big boxers combine intrinsic talent with skill developed over years of training to produce some pretty powerful punches. I contributed to the section "Properties of Power" on page 63. A few more of my comments appear on pages 64-65.
It was a lot of fun working on the piece. The human body is capable of delivering enormous amounts of power over short time intervals. Tour de France cyclists can briefly output over a kilowatt. Boxers can surely do that over a the brief time of a monster punch. There is no way I would want to be on the receiving end of one of those punches!
