Effects of Volleyball Movements on the Nailfold Microcirculation in Female College Students

目的：探讨排球运动对女大学生甲襞微循环的影响。方法：应用显微电视录像技术，观察女大学生排球运动不同阶段甲襞微循环的变化。结果：排球运动可使甲襞微血管畸形消失（P〈0．05～O．01）、口径增宽（P〈0．05～0．01）、红细胞聚集消失（P〈0．01）、微血流流态显著改善、流速加快（P〈0．05～0．01）、微循环积分值显著降低（P〈0．01）。结论：排球运动对女大学生甲襞微循环有明显改善作用。

Objective：To study the effect of volleyball movements on the nailfold microcirculation in female college students. Methods.. The changes in nailfold microcirculation were studied by using a vital microscope with TV recorder before and during the four stages of volleyball sport. Resuits： The micro-vessels shape and the micro blood flow speed were changed（P〈0. 05～0. 01） ;the diameter of micro-vessels was increased（P 〈 0. 05 ～ 0. 01） ;the red aggregated cell disappeared（P〈0. 01）, the total score value was obviously decreased among all stages of volleyball sport（P〈0. 01）. Conclusion：volleyball sport could markedly improve nailfold microcirculation for the female college students.
