David,
The numbers you quote are claiming walking and playing golf to be 5x-8x the baseline energy expenditure. That's ridiculous. There's a compendium someone came up with years ago that gives every conceivable kind of activity in terms of how many times a person's baseline metabolic rate that activity requires.
That compendium lists golf, walking and carrying to be a 4.5x activity based on actually hooking golfers up to metabolic calorimeters. An early version of the compendium used some wild-ass guesstimates much higher than that based on no evidence at all. In 1993 the golf numbers were revised downward, once they got around to actually measuring the energy expenditure.
There's a lot of info out there in the literature based on purely speculative guesswork back in the 80's about physical activity. In the past 15-20 years actual measurements have been taken, giving more realistic estimates. A lot of these calculators and third-hand sources are based on ancient, discredited guesswork.
I'm not a doctor, and I don't play one on TV either...and I didn't stay in a Holiday Inn express last night.
Brent, you are either a doctor, or a fitness professional I am assuming. But, could you support your assertions with anything the rest of us could read up on? It would be nice to know a reasonable estimate for what a walking, carrying round of golf results in calorie burning. And...to determine why every single reference we can find on the internet says it's higher than you suggest.
I agree with David that not everything on the internet is true, but I can't find anything to support your thesis. From everything I've read, the caloric burn is between 1200 and 1500 for a round of golf, while walking, and carrying one's golf bag. I can see how it is much more than jogging for an hour, because of the practice swinging and shot hitting, walking, and carrying a load on your back all together.
The main point I was making is that we should all be walking, whether it be 36 holes, 18 holes, 9 holes, or 4 holes. It's hard to find a golf cart in the UK. Golf carts are an American invention (yet another way the US has managed to lower this great game....insisting on medal play, the 5 hour round, etc. are others). My point was the game and all who play it would be better off if this "innovation" had never come to pass.
