A Three-Dimensional Study of Body Motion During Ergometer Rowing

Abstract

Abstract:Background: Rowing movements can be simulated using specialized ergometers; the method can be used both for training and indoor assessment of body movements within controlled conditions.Purpose: To perform a three-dimensional quantitative analysis of body movements during ergometer rowing, and to examine if there is a relationship between anthropometry and rowing kinematics. Study Design: Descriptive Laboratory StudyMethods: Body movements were recorded in 18 high-level oarsmen during ergometer rowing at 28 strokes/min. The three-dimensional movements of 21 body landmarks (left and right ankle, knee, greater trochanter, hip, shoulder, elbow, wrist, tragus; spinous process of C7, T2, T12, L2, L4) were detected by an optoelectronic instrument. Using dedicated software¸ the range of motion of the posterior angles of the cervical, thoracic and lumbar spine segments relative to the horizontal axis; the angles between greater trochanter-knee-ankle and between knee-ankle and the ground; head rotation and tilt; leg and upper limb symmetry, were computed. Results:The head and neck were approximately in line with the horizontal at catch, and extended at finish, with limited horizontal and frontal plane inclinations. Thoracic spine extension during the stroke was on average 68°. Lumbar spine range of motion was on average 59°, and it was smaller in weightier oarsmen. Upper limbs were symmetric, and a complete, symmetric extension of the lower limbs was made. At catch the legs were nearly perpendicular to the ground. Conclusions:The method allowed the measurement of the kinematic characteristics of the body during ergometer rowing. The measurements agreed with conventional technical teaching.Clinical Relevance: Data collected on high-level rowers can provide a set of standard quantitative execution parameters that can be used by coaches as a benchmark for the assessment of technical movements in all rowers.

The Kinematics of Fixed-Seat Rowing: A Structured Synthesis

“…Olympic sliding-seat rowing is a sport that has been extensively researched and investigated from various aspects [1], including physiological parameters [2,3], psychological characteristics of the athletes [4,5], injuries [6][7][8], coordination [9,10], power output with an emphasis on the analysis of force/power curves [11], and athlete testing [12,13], as well as tactical strategies [14,15]. Other studies opted to focus on kinematics through measurements made [16][17][18] in the laboratory on ergometers and/or on water [19,20]. In contrast, however, the technique of fixed-seat rowing, a more classic form of the sport [21] that is still widely practised in various European countries, has been sparsely studied [22][23][24][25][26], and detailed knowledge about its kinematics acquired with modern instrumentation is limited to studies that focus on para-rowing [27].…”

Diseño para la adaptación e instrumentación de una máquina de remo a ser usada en sujetos con lesión medular

“…En algunos casos se considera el ejercicio de remo como un movimiento uniplanar desarrollado en el plano sagital, utilizando un sensor de posición ubicado en la silla de la máquina para obtener los datos de la translación antero-posterior de la cadera, y de esta manera calcular el movimiento de la rodilla en flexión y extensión [14]. Por otro lado, se encuentran los sistemas optoelectrónicos, con los cuales se realiza el análisis cinemático tridimensional de las diferentes articulaciones [10,[15][16][17][18][19]. Para el análisis cinético se hace uso de sensores de fuerza unidireccionales para determinar las fuerzas de reacción a nivel de los miembros superiores [10,16,[19][20][21], y para medir la fuerza normal del apoyo de los pies [21], junto con el uso de las plataformas de fuerza [18,19].…”

Specialized Movement on the Rowing Ergometer and Post-workout Changes in Selected Peripheral Blood Parameters - a Case Report.

“…Ever-changing environmental conditions typically found during on-water rowing testing cause significant standardisation problems. For this reason, we use the rowing ergometer, which simulates properly the action of onwater rowing in our research (Akça, 2014;Sforza, Casiraghi, Lovecchio, Galante, Ferrario, 2012).…”
