Golf Swing – Muscle Activation in Follow-Through
If these muscles aren’t active during the follow through of your golf swing, then you can be at risk for injury!
During the early and late follow-through phase of a golf swing, the external obliques on the dominant side and the internal obliques on the non-dominant side are very active in order to decelerate the club. The rotator cuff muscles act in a similar way, specifically the subscapularis (arm internal rotator) on the dominant side and the infraspinatus (arm external rotator) on the non-dominant side. Essentially, all of these muscles are working together to control the movement of the swing.
A weakness of the oblique or rotator cuff muscles throws a wrench in this synergistic relationship.
- If the obliques can’t properly aid in the deceleration process, then the rotator cuff muscles listed above must work much harder. Repeated excessive activation of the rotator cuff muscles can lead to shoulder dysfunction and injury including instability, strain, or even tears.
In addition to strength in these muscles, we need them to activate at the proper time during our swing. We can work on this timing with drills and warm-ups that focus on the above-listed musculature.
Bottom Line: It is crucial for golfers to establish and maintain strength in their oblique and rotator cuff muscles and ensure these muscles are activating at the proper time in the golf swing to maximize club speed and also help prevent injury!
