目的通过对婴儿进行游泳训练,观察对其骨骼强度的影响。方法随机抽取235例30～42d健康婴儿分为两组,游泳组115例,对照组120例。游泳组每周2～3次游泳训练,对照组仅进行正常沐浴。两组婴儿满6个月时观察骨强度的变化。骨强度测试采用以色列Sunlight公司生产的Omnisense TM7000P骨强度B超仪,检测婴儿非用力侧(左)胫骨中段传播的超声波速度SOS(m/s)。结果游泳组婴儿骨强度(3167.88±106.23)m/s明显高于对照组(3052.67±99.63)m/s,差异有统计学意义(P﹤0.05)。游泳组婴儿骨强度异常率25.2%明显低于对照组37.5%,差异有统计学意义(P﹤0.05)。结论游泳对婴儿的骨强度有显著的影响,能增加婴儿的骨强度。由于这项运动简便易学,并且效果显著,值得向家长普遍推广。
Objective To observe the effect of infants on their strength by swimming training. Methods 235 healthy infants from 30 to 42 days were randomly divided into two groups: swimming group (115 cases) and control group (120 cases). Swim group 2 to 3 times a week swimming training, control group only for normal bathing. Changes in bone strength were observed in both infants at 6 months of age. Bone Strength Test Ultrasound velocity SOS (m / s) transmitted from the non-forcing (left) tibial mid-tibia in infants was measured using the Omnisense ™ 7000 Bone B scale from Sunlight, Israel. Results The infantile bone strength in swimming group (3167.88 ± 106.23) m / s was significantly higher than that in control group (3052.67 ± 99.63) m / s, the difference was statistically significant (P <0.05). The abnormal rate of bony strength in swimming group was significantly lower than that in control group (25.2% vs 37.5%, P <0.05). Conclusion Swimming has a significant effect on the infant’s bone strength, which can increase the baby’s bone strength. Because of this sport is simple and easy to learn, and the effect is remarkable, it is worth to the general promotion of parents.
