Jackson Koivun
After Ryan Fox’s win last week, side bend in the golf swing, and the role it plays in injury risk got a lot of attention. Here we can see another excellent player, and very exciting prospect Jackson Koivun also demonstrating a large amount of side bend.
Like many things, people have strongly held beliefs on this subject. A lot of it is unsupported by rigorous research, and is predominantly from single player case studies.
The body of published scientific research on swing mechanics and injury risk does not show a conclusive link. There are been two systematic reviews that dig into this question specifically. Watson et al 2023, and Smith at al 2018. You can look them up.
This does not mean there isn’t a link, it just hasn’t been shown.
Swing mechanics play a huge role in where stress is placed, but stress does not necessarily mean injury, as the body is so amazingly adaptable. We see lots of examples of this throughout sports.
Injury is very complex. There are golfers with very neutral swing mechanics with debilitating pain, and golfers with extreme mechanics that don’t have any issues. The golf swing is a stressful move in general!
It is definitely an area where longer term and higher quality research is needed.
I wrote a short review of the available research on this topic in my latest newsletter. If you comment research, it will be DM’ed to you.
