1 The purpose of this study was to compare the electromyography (EMG) patterns of the thoracic and 2 lumbar regions of the erector spinae (ES) muscle during the golf swing whilst using four different golf 3 clubs. Fifteen right-handed male golfers performed a total of twenty swings in random order using 4 the driver, 4-iron, 7-iron and pitching-wedge. Surface EMG was recorded from the lead and trail 5 sides of the thoracic and lumbar regions of the ES muscle (T8, L1 and L5 lateral to the

No significant differences 8 in muscle-activation levels from the lead and trail sides of the thoracic and lumbar regions of the ES 9 muscle were displayed between the driver, 4-iron, 7-iron and pitching-wedge (P > 0.05). The highest 10 mean thoracic and lumbar ES muscle-activation levels were displayed in the forward swing (67 -99% 11 MVC) and acceleration (83 -106% MVC) phases of the swing for all clubs tested. The findings from 12 this study show that there were no significant statistical differences between the driver, 4-iron, 7-13 iron and pitching-wedge when examining muscle activity from the thoracic and lumbar regions of 14 the ES muscle. 15 16
