This isn't what's meant by push cart
In the U.S., more and more courses are going cart only to increase profits, but research shows that this also increases scores. Neil Wolkodoff,the director of the Center for Health and Sport Science at the Rose Medical Center in Denver, found that golfers scored lower while walking with a caddie or with their clubs on a push cart than they did when using a motorized cart. Surprisingly, the highest average scores came from golfers carrying a golf bag.
Why is this? Well, it all has to do with how much energy it takes to golf. Golf might seem like a sedate sport to non-golfers, but Wolkodoff found that a round of golf uses a lot of energy. The most energy was expended while walking with a bag (721 calories burned for nine holes). Walking with a push cart burned just a little less (718). Walking with a caddie burned 621 calories for nine holes, and riding in a cart still burned 411 calories on average. Swinging a club involves the whole body and doing that 100 times over nine holes burns a lot of energy.
