Dr Andy Franklyn-Millers says this would not only help youngsters with health problems, but would also identify future sports stars.
Unions and the Youth Sport Trust, however, say testing would be counter-productive.
Dr Franklyn-Miller writes on the BBC health website that schools are putting the physical competence of future generations at risk by failing to give PE the same priority as other subjects on the curriculum.
He argues that help is available for kids who struggle with English or maths, but not with PE. He would like to see a similar approach used for what he calls "physical literacy".
He says: "Let us achieve future success now by building in a PE curriculum that embraces push, pull, squat, brace, rotate, accelerate and change of direction."
Dr Franklyn-Miller added the tests should be compulsory as children progress through their school career.
What do you think?
Could you see such testing having any benefit?
