Modelling in Rowing
Published in Youlian Hong, Routledge Handbook of Ergonomics in Sport and Exercise, 2013
Rowing is a sport consisting of a continuous cyclical movement, which demands efficiency and accurate coordination of the full body to maximize performance. The rowing cycle is formed by the rower sliding back and forth along a monorail through the action of cyclical extension and flexion of the lower limbs. This general concept refers to different sports; for instance, the sport where the subject pulls one oar (in boat or indoor) and the ergometer rowing. In the ergometer rowing, the subject pulls a handle, which is connected to the flywheel that generates the rowing resistance. In recent years, this rowing motion has become a new competitive sport, a training for on-water race-pace rowers or simply an indoor exercise for healthy purposes. A statistical analysis describing motion and load characteristics of ergometer rowing is used to test the hypothesis that rowing stroke technique is associated with the incidence of low back pain (see O’Sullivan et al., 2003). Indeed, the use of the values obtained for the torques may improve performance and prevent injuries such as chronic back pain (Bartlett and Bussey, 2011).
Robust Monitoring of Sport and Exercise

Rowing is a high-tech sport with considerable research into all aspects of the equipment including the shape of the shell. Modern rowing shells are often carbon fibre composites carefully designed to minimize drag. For many years the most common piece of electronic technology used with rowing boats was the impeller. This was a small propeller attached under the boat at a carefully chosen position where it would not increase the drag of the boat. The rotation rate of the impeller, and hence the speed of the boat, was detected by a magnetic sensor fitted inside the shell immediately above the impeller. Although the impeller itself had a negligible contribution to drag, usually less than 0.1% of total drag, the impellers catch water-borne material, sometimes increasing the drag to a detectable level. The impeller can also get clogged and not rotate freely or even come off and be lost. Research into the use of alternate sensors initially considered accelerometers as a replacement for the impeller. As discussed later in this chapter, this was not a particularly appropriate use of the technology, as extracting velocity was and is problematic. In researching this problem the acceleration signal was recognized as a valuable resource. When the accelerometer output was first synchronized with video, coaches immediately recognized the value of this signal as it allowed them to see the power pulses and deceleration of the boat. With the use of the video, the causes of unexpected decelerations were identified, and changes to the rowing style were implemented. Ultimately, accelerometers were combined with other technology, in particular the GPS, to create a rowing unit. This technology has been used by elite Australian rowing teams since prior to the 2004 Athens Olympics. (Land Victoria 2005; Prime Minister’s Science, Engineering and Innovation Council 2004).
Increased foot-stretcher height improves rowing performance: evidence from biomechanical perspectives on water

Rowing performance is mainly dependent on a rower’s ability to develop large forces on the foot-stretcher, which are transferred by the trunk and upper limbs to the oar to maintain a higher mean boat velocity (Baudouin & Hawkins, 2002; Buckeridge, Bull, & McGregor, 2015).The foot-stretcher provides a solid platform against which the rower can apply large muscle power by rapidly extending their knees in the early drive phase, which is known as leg drive (Nolte, 2005, pp. 165–172). Currently coaches and rowers select the foot-stretcher height according to the comfort of rowers, rather than optimisation of performance (Buckeridge, Weinert-Aplin, Bull, & McGregor, 2016; Buckeridge, Bull, & McGregor, 2014; Soper & Hume, 2005). Therefore, it is necessary to provide the quantitative data to coaches and rowers about the influence of foot-stretcher height on biomechanical parameters, especially in on-water rowing.
