| 内容記述 | The purposes of this study were to clarify the kinetics of muscle oxygenation (Oxy-Hb, Deoxy-Hb) by near infrared spectroscopy (NIR) in the decreasing force phase, especially the pre- and post-phases of the inflection point, in sustained maximal static gripping (SSG), and to examine the relationship between kinetics of muscle oxygenation and force-decreasing parameters. The experiment was conducted on 20 male subjects aged 15-18 years. The time at the lowest Oxy-Hb value (20.5±5.5s) significantly correlated with the decreasing times of forces of 40, 60 and 80% of maximal voluntary contraction (MVC), and the rate of decreasing force for 0-1 min (r=.60, .53, .49, and -.63 respectively). These parameters reflect the decreasing force based on the oxygenation deficiency into the muscle with the obstruction of the blood flow. The time of reaching the highest Deoxy-Hb value (46.8±15.Os) and the regression coefficient in the Deoxy-Hb decreasing phase correlated significantly with the decrement for 1-2 min. This parameter evaluates the phase where resumption of the blood flow began, and Deoxy-Hb in the tissue was eliminated. The inflection point of the gripping force is related to the time at the highest Deoxy-Hb, and reflects the beginning and the resumption of the blood flow. The decrement for 2-3 min and the regression coefficient of post-inflection point evaluate the steady state phase of force decreasing, in which oxygen is sufficiently supplied to active muscles.
