Effect of leg immobilization after knee surgery on muscle oxygenation and blood volume

摘要

Introduction. -The aim of this study was to assess effects of a leg immobilization period following surgical of knee on muscle oxygenation (OXY) and blood volume (VS) monitored with Near Infrared Spectroscopy (NIRS).Methods and results. - Sixteen amateur soccer players having undergone anterior cruciate ligament reconstruction and eight healthy subjects (control group) took part in this study. From horizontal leg press, the subjects carried out a graded test on each leg. At each submaximal power (absolute values), OXY were significantly higher in non-surgical leg, on the other hand the data of the VS are identical in both legs. No difference was observed for the control group. Conclusion. -The technique of near infrared spectrometry could objectify the peripheral adaptations in response to a phase of reduced activity.
