The purpose of this study was to compare the biomechanical characteristics of the lower body swing to modern swing techniques, with a focus on lower back injury risk. Fifteen male individuals free from lower back injury participated in this study. Nine participants utilized the modern swing (age = 48.0 ± 13.6 years; height = 176.8 ± 4.4 cm; mass = 82.1 ± 5.3 kg) while six utilized the lower body swing (age = 53.9 ±12.1 years; height = 182.9 ± 6.1 cm; mass = 92.5 ± 14.8 kg). Whole body kinematics were recorded with a ten-camera motion analysis system while individuals performed 5 shots with a driver for maximum distance. Continuous waveform and discrete point analysis was used to explore the differences between these two techniques. The lower body swing demonstrated favourable kinematics in the majority of variables related to lower back pain and lumbar load.
