“…111,168 Maximum flexion of the lumbar spine correlated with toe off in the gait cycle while maximum extension occurred near the timing of heel strike. 169 Walking and running both result in cyclic impacts to the body with each step which in turn applies a cyclic (or dynamic) load to the spine.…”

The goal of this review is to discuss the mechanisms of postural degeneration, particularly the loss of lumbar lordosis commonly observed in the elderly in the context of evolution, mechanical, and biological studies of the human spine and to synthesize recent research findings to clinical management of postural malalignment. Lumbar lordosis is unique to the human spine and is necessary to facilitate our upright posture. However, decreased lumbar lordosis and increased thoracic kyphosis are hallmarks of an aging human spinal column. The unique upright posture and lordotic lumbar curvature of the human spine suggest that an understanding of the evolution of the human spinal column, and the unique anatomical features that support lumbar lordosis may provide insight into spine health and degeneration. Considering evolution of the skeleton in isolation from other scientific studies provides a limited picture for clinicians. The evolution and development of human lumbar lordosis highlight the interdependence of pelvic structure and lumbar lordosis. Studies of fossils of human lineage demonstrate a convergence on the degree of lumbar lordosis and the number of lumbar vertebrae in modern Homo sapiens. Evolution and spine mechanics research show that lumbar lordosis is dictated by pelvic incidence, spinal musculature, vertebral wedging, and disc health. The evolution, mechanics, and biology research all point to the importance of spinal posture and flexibility in supporting optimal health. However, surgical management of postural deformity has focused on restoring posture at the expense of flexibility. It is possible that the need for complex and costly spinal fixation can be eliminated by developing tools for early identification of patients at risk for postural deformities through patient history (genetics, mechanics, and environmental exposure) and tracking postural changes over time.

“…Em nosso estudo aplicamos um protocolo de medição com base na fixação de hastes sobre as vértebras lombares e os resultados revelaram que durante a pedalada, um comportamento parecido com o encontrado para a marcha (SCHACHE et al, 2002;WHITTLE;LEVINE, 1999) O estudo do movimento pélvico durante o ciclismo utilizando análise de vídeo foi objetivo de estudo de Neptune e Hull (1995). No eixo X (inclinação lateral) as maiores amplitudes foram encontradas entre o segundo e o terceiro quadrantes do ciclo (180°), e as menores amplitudes no início e no final do ciclo.…”

“…Quanto ao comportamento pélvico ao longo do ciclo de pedalada, ocorreu maior flexão no início, meio e fim do ciclo, enquanto que a maior inclinação lateral e rotação ocorreram ambos no meio do ciclo (180° ou PMI). Resultados muito semelhantes a estes foram encontrados por Schache et al (2002), ao longo de um ciclo de passada, avaliando o comportamento angular da coluna lombar durante a corrida e aos encontrados no presente estudo avaliando o ciclo de pedalada. Isso sugere grande similaridade no comportamento angular da região lombar comparando a marcha e o ciclismo.…”

A prática do ciclismo não abrange somente ciclistas e triatletas profissionais, mas também a população em geral. Para estes, a bicicleta também é considerada um excelente meio de transporte e lazer WANG, 1998). Na prática do ciclismo, como forma de atividade física regular, é necessário levar em consideração a correta postura do ciclista, principalmente no que tange o ajuste do selim. Isto é necessário para evitar desconfortos e dor, o que pode causar problemas na coluna, sendo este um dos fatores para o abandono deste esporte (MARTINS et al., 2007).Os aspectos relacionados à ergonomia no ciclismo envolvem, principalmente, o ajuste correto da interação ciclista-bicicleta na busca tanto por conforto como por desempenho. Além dos prejuízos na técnica e na eficiência, ciclistas são regularmente confrontados com lesões e dores crônicas causadas por desvios na postura adequada na bicicleta, tais como o aumento da flexão de quadril e de joelho (BURKE, 1996), o que tem sido efetivamente minimizado quando o posicionamento é correto (BURKE, 1996;VAN HERP et al., 2000).As análises cinemáticas da coluna têm sido conduzidas a fim de identificar fatores de risco para a ocorrência de lombalgia, que pode ser recorrente entre ciclistas. No ciclismo, a busca por um método padrão para análise cinemática da coluna lombar limita-se aos poucos estudos e Motriz, Rio Claro, v.18 n.4, p.783-794, out./dez. 2012 Artigo Original Efeito da altura do selim na cinemática da lombar de ciclistas Effect of saddle height on the kinematics of lumbar spine of cyclistsAbstract: The aim of this study was to analyze the influence of saddle height on the kinematics of the lumbar spine during cycling. Eight recreational cyclists were assessed in an usual situation (self-selected) and the situation of saddle properly adjusted while pedaling with a load set at 150 W. Using two-dimensional kinematic the angles of flexion, lateral inclination and rotation of the lumbar spine were computed. The flexion was greater in the adjusted position whereas the highest average tilt and rotation angles occurred in the usual position. There were two cycles of flexion-extension observed during a complete pedaling cycle, and only one cycle of lateral inclination and rotation. The major differences were observed at early, middle and end of the pedaling cycle. The mismanagement of the saddle did not involve significant changes in the kinematics of the lumbar spine for the conditions tested.

“…Three-dimensional (3D) computerized motion analysis systems are routinely used in gait analysis research and in clinical practice, and have been applied in evaluating lower limb and lumbopelvic motion during functional tasks [1] .The use of various 3D systems for evaluating joints' kinematics has been previously investigated [2]. The VICON system is an optical tracking system which tracks three-dimensional movement trajectories of reflective markers with up to 1mm accuracy.…”

Abstract. Three-dimensional optical systems are used for calculating many kinetic and kinematic parameters. The obtained data are precise; however, their repeatability is a very important aspect. The aim of this paper is to verify the range of motion repeatability of one healthy subject in the joints of the pelvis, spine and lower limbs based on the coefficient of variation. The participant performed seven exercises, repeated five times: two-leg squat, single-leg squat, forward bending, forward-step motion, step onto the stair, hip extension in a standing position and tip-toe extension while standing. Motion was recorded using Vicon motion capture system consisting of eight NIR cameras. The participant had 39 markers attached to her body according to the Plug-in Gait model. The coefficient of variation was calculated in three dimensions (X, Y and Z). The greatest repeatability, pursuant to the coefficient, was observed during the two-leg squat and forward bending in the sagittal plane (X coordinate). It was also high during the singleleg squat. The lowest repeatability was observed during the tip-toe extension while standing and the hip extension in a standing position. During the step onto the stair and the forward-step motion, a higher repeatability of measurement occurred in the open kinematic chain than in the closed chain; in the hip extension the reverse occurred. Repeatability of a range of motion is different in two types of kinematic chain and in 7 exercises. Exercises such as tip-toe extension and hip extension, which require a greater ability to balance, indicated more variability in movement.
