The relationship between biomechanical variables and driving performance during the golf swing

Area of Science:

• Sports Science
• Biomechanics
• Kinesiology

Background:

• Understanding the biomechanical factors influencing golf ball velocity is crucial for performance enhancement.
• Previous coaching methodologies often relied on anecdotal evidence for improving driving distance.

Purpose of the Study:

• To identify key kinematic and ground reaction force variables that significantly correlate with golf ball velocity.
• To provide empirical data supporting or refuting common golf swing coaching principles.

Main Methods:

• Analysis of kinematic data and ground reaction forces from 308 golfers during the golf swing.
• Application of regression models at four distinct phases of the swing to determine variable importance.

Main Results:

• Regression models explained 44-74% of the variance in ball velocity.
• Significant factors identified include upper torso-pelvis separation (X-Factor), delayed release of arms and wrists, trunk tilting (forward and lateral), and weight shifting.
• Results validated several established coaching concepts related to increasing ball velocity.

Conclusions:

• Specific biomechanical elements like the X-Factor and delayed release are critical for maximizing golf ball velocity.
• The findings offer evidence-based guidelines for golfers seeking to improve swing mechanics and power.
• This research can inform targeted skill and strength training programs for golfers aiming for greater driving distance.
