Once you start getting a clearer understanding of the golf swing and go searching for some of the more technical nuances it has to offer, you will likely hear about ground forces. But what exactly are these ground forces and how do they affect the golf swing? We had GOLF Top 100 Teacher Mark Blackburn break it down for us in today’s Home Practice. Watch the video above or keep reading for more.
“Simply put, they are the response
to our action forces pushing down on the ground,” Blackburn says. “When you
think of Newton’s second law, for every action there’s an equal and opposite
reaction, that’s what ground reaction forces are.”
Essentially it boils down to how you use the ground to your advantage to generate more clubhead speed. And to generate that speed using the ground there are a couple of ingredients to consider.
The first is your center of mass and how it moves. In simpler terms, this is your weight shift in the swing.
“Think about your movement of mass,
or your displacement, toward your trail leg and then back towards your lead leg,”
Blackburn says. “That’s really important, the relationship of where your mass
is.”
The next ingredient is your
vertical force, which is how hard you’re pushing your trail leg and your lead
leg into the ground. This pressure gives you your combined vertical force. With
this, you want to get your ground pressure shifting to your lead leg while your
center of mass stays relatively back.
“A simple way to get this sensation
is to turn into your trails side and then have the sensation that you’re maintaining
your mass or weight back and then your pressure is shifting forward,” Blackburn
says. “That’s going to allow you to optimize your pressure and its relationship
to your mass.”
