Height and muscle strength have reportedly changed among Japanese youth during the past 10 years. Height has increased, and the back muscles have become weaker than 10 years ago. We compared the lumbar lordosis of youth today (113 men and 76 women) and of 10 years ago (85 men and 62 women). Lumbar lordosis and sacral inclination were measured on lateral standing radiographs of the lumbar spine. We also measured the same parameters among adults today (63 men and 63 women) and 10 years ago (56 men and 73 women) to study postural changes in another generation. In both men and women, the lumbar lordosis and the sacral inclination of youth today were approximately 10 degrees larger than they were 10 years ago ( P < 0.0001). However, there was no significant difference between the values among adults today and those of the same generation 10 years ago.
据报道，在过去10年里，日本年轻人的身高和肌肉力量发生了变化。身高有所增加，且背部肌肉比10年前变弱了。我们比较了如今的年轻人（113名男性和76名女性）与10年前的年轻人（85名男性和62名女性）的腰椎前凸情况。在腰椎的站立位侧位X线片上测量腰椎前凸和骶骨倾斜度。我们还测量了如今的成年人（63名男性和63名女性）与10年前的成年人（56名男性和73名女性）的相同参数，以研究另一代人的姿势变化。在男性和女性中，如今年轻人的腰椎前凸和骶骨倾斜度比10年前大约大10度（P < 0.0001）。然而，如今成年人的这些数值与10年前同一代成年人的数值之间没有显著差异。
