青少年的骨胳硬度小,韧带肌肉也较薄弱,因而主要受骨胳肌肉影响的身体形态就容易产生各种变形。所以在讲授“骨胳”一节时,应要求学生在日常生活中,注意保持正确的坐、立、行的姿势,例如在做作业时,不要扭腰斜肩;站立要挺胸收腹,做到古人所说的:“站如松,坐如钟。”否则将会引起脊椎向一侧弯曲或者驼背,影响体态的正常发育和体形的美 The skeletal hardness of adolescents is small, and ligamentous muscles are also weak. Therefore, body shapes that are mainly affected by skeletal muscles are prone to various deformations. Therefore, when teaching the “bone” section, students should be required to pay attention to the correct posture of sitting, standing and walking in daily life. For example, when doing homework, do not twist the shoulders; stand up and take care of your abdomen; Do what the ancients said: “The station is like a pine, sit like a bell.” Otherwise it will cause the spine to bend to one side or hunched back, affecting the normal development of the posture and the beauty of body shape.
