PURPOSE : The purpose of this study is to compare sagittal spinal alignment and mobility among standing and sitting (which are fundamental postures in daily activities), and four point kneeling (FPK: the imitation of quadrupedal animal posture).
METHODS : Fifty three healthy young men have participated in this study. Spinal alignment is measured using a non-invasive skin surface measurement device (Spinal Mouse®: Index Ltd, Japan). The spinal alignment is measured in 3 positions: upright, flexion, and extension, in each posture (standing, sitting, and FPK), and then the thoracic and lumbar curvature and sacral slope are analyzed.
RESULTS : Even between 2 fundamental positions, upright standing and sitting, the lumbar lordosis is statistically different (17.1±8.9° at upright standing, 3.5±10.0° at upright sitting, p<0.001). But the sacral slope is not different between those 2 positions. The lumbo-pelvic rhythm (lumbar-hip or lumbar-pelvis flexion ratio) is also different among the 3 postures, especially in FPK posture. In this posture the lumbar spine and pelvis (sacrum) move to opposite direction each other; this phenomenon is not observed at standing and sitting postures.
CONCLUSION : The spinal alignment and mobility are different in many segments among standing, sitting, and FPK., The Japanese Society of Physical Fitness and Sports Medicine - 314. 小学生の足底圧分布の経年変化(加齢・性差,一般口演,第63回日本体力医学会大会)

Url, Downloadable, I introduced the exercise program conducted in the senior walking class of the Teikyo Heisei Sports Academy, the number of steps for each walking course and the calorie consumption measured by the activity meter (estimated value) as a quantification of the amount of exercise, and the change in stride and pitch before and after training as a quantification of the change in the quality of walking.
