Purpose The kinetic profile of golf swings is frequently assessed in biomechanics.However,most research is limited to young golfers,so the mechanical demands on older athletes are poorly documented.This study provides kinetic data of older golfers swinging with a driver and a 6-iron.Methods We examined 17 older,skilled male golfers(62.2±8.8 years,handicap 8.7±4.9)using a 10-camera motion cap-ture system and two force platforms.Three-dimensional net support moments,joint moments of the hip,knee,and ankle,ground reaction forces(GRF),and the inclination angles between the centre of mass(COM)and centre of pressure(COP)were calculated and tested for between-club differences.Results The 3D net support moments of the trail leg were higher when using the driver,while those of the lead leg were higher with the 6-iron.Between-club differences existed in the relative contribution from each joint,the COM-COP inclina-tion angles,and the peak GRF.Conclusion The mechanical demands of golf swings on older adults differ between a driver and a 6-iron,which likely affects the balance and control strategies required.This improved understanding of the kinetic profiles of golf swings in older adults provide clinicians and coaches better means to maintain older golfers active and healthy for longer.
