局部振动刺激对肱二头肌血红蛋白的影响

Effect from local vibration stimulus on hemoglobin change of biceps muscles

目的探讨局部振动刺激过程对肱二头总血红蛋白和氧合血红蛋白的影响。方法利用手臂振动按摩带对12名女性志愿者进行局部振动刺激,用非侵入性近红外光谱仪于振动开始前10 min、振动中10 min与振动停止后15 min采集肱二头肌之总血红蛋白和氧合血红蛋白的数值,并了解每分钟变化趋势;以单因素方差分析进行统计检验。结果振动停止后15 min会使手臂肱二头总血红蛋白显著性增加(P<0.05),振动中10 min与振动停止后15 min均会使手臂肱二头氧合血红蛋白显著性增加(P<0.05);在变化趋势方面,总血红蛋白和氧合血红蛋白约在振动中10 min的第5 min出现最大峰值,且在振动停止后15 min仍持续高于振动刺激前,并呈现稳定状态。结论局部振动刺激会实时提升肱二头总血红蛋白和氧合血红蛋白;此外,必须至少持续振动刺激5 min以上总血红蛋白和氧合血红蛋白数量才会达到最大峰值。

Objective To investigate the effect from local vibration stimulus on the total hemoglobin and oxygen hemoglobin change of biceps muscles. Methods Arm Vibration Massage Band was used by twelve volunteers （female college students） to receive the local vibration stimulus. By using the Near Infrared Spectroscopy, the total hemoglobin and oxygen hemoglobin of biceps muscles were measured at 10th minute before vibration, 10th minute during vibration and at 15th minute after vibration, respectively, to get the variation tendency at each mi- nute. Repeated measured one-way ANOVA was used to compare the differences in the test results. Results The total hemoglobin of biceps muscles was significantly increased at 15th minute after vibration （P 〈 0.05）, and the total oxygen hemoglobin of biceps muscles was significantly increased at 10th minute during vibration and 15th minute after vibration （P 〈 0.05）. The maximum value of the total hemoglobin and oxygen hemoglobin occurred at 5th minute during 10-minute vibration stimulus, and compared with 10th minute before vibration, the total hemoglobin and oxygen hemoglobin could continue to be higher at 15th minute after vibration with a stable tendency. Conclusions The local vibration stimulus can acutely increase the total hemoglobin and oxygen hemoglobin of biceps muscles, which can reach the maximum value with sustained vibration stimulus for at least 5 minutes.
