体育锻炼对身体发育有哪些好处和坏处？

科学研究证明：小学生坚持上好体育课，积极进行体育锻炼，可以使骨质增强，促进生长发育，使儿童身高迅速增长。
因为体育运动时，肌肉对骨骼的牵拉和重力作用，不仅有利于改善骨的形态和机能，使骨骼变的粗实、坚固，也有利于脊柱，胸廓，骨盆，足弓等骨骼的正确形成，还会使骨骼的机械性能得到提高。
但是，锻炼不科学，也会给骨骼带来不利的影响，所以，体育老师一定指导学生按科学的方法进行锻炼。
2. 体育锻炼对关节的影响：
通过体育课的学习和锻炼，能使关节囊、韧带和肌腱增厚，伸展性加大，关节周围的肌肉力量和弹性增加，这样，就会使关节活动范围加大，灵活而又牢固。如体操运动员，杂技演员其柔韧性之好，充分说明了体育锻炼的惊人作用。

肌肉可以变的粗壮、结实、有力。可使肌肉中物质和能量代谢过程加强。可以提高神经系统对肌肉的控制能力。可以减少肌肉内的脂肪堆积，使少年儿童肌肉发育均衡，体态端正，防止肥胖症。
