ABSTRACT
The rowing technique used for a single scull requires repetItIve flexion and extension of the trunk, upper and lower limbs. This technique predisposes the rower to injury to the structures of the lower back. In fact, the lower back has been the most common site of injury and pain for rowers (Motto, 1994; Reid, 1997; Soghikian, 1995). A number of factors have been proposed to explain why back pain has been a common complaint: (1) evolution of the modem style of rowing, which puts more strain on the back (Stallard, 1980), (2) introduction of continuous, high intensity training techniques (Stallard, 1980), (3) increased volume of training, (4) lack of proper supervision during weight training sessions, and (5) the introduction of bigger blades (Hatchet blades) for the oars. It has been speculated that the Hatchet blades increase the load on the lower back, particularly during the beginning of the stroke (Nolte, 1993), which has implications for injury. The purpose of this study was to determine the compressive force developed in the lower back during the rowing performance and compare the magnitudes between the trials with Macon sculling blades and with Hatchet sculling blades.
