AbstractCurrently, near infrared spectroscopy has a clear potential to explain the mechanisms of fatigue by assessing muscle oxygenation. The objective of the study was to observe the changes in muscle oxygen consumption after an official women’s soccer match. The sample was 14 players who competing in the second division of Spain of women’s soccer. They were evaluated before, immediately after and 24 h after the official match. Biochemical parameters were measured in blood plasma (BUN, GOT, LDH, CPK). The jumping in countermovement, perceived exertion and perceived muscle pain were also assessed. The muscle oxygen consumption and muscle oxygen saturation were evaluated in the gastrocnemius muscle with an arterial occlusion test. ANOVA of repeated measures, Pearson’s correlation and Hopkins’ statistics were applied to measure the magnitudes of change and effect size. There was observed an increase in kinetics of SmO2 at 24 h after the official match, using arterial occlusion. In addition, it was found that the increase in muscle oxygenation correlated with fatigue indicators, such as the increases in LDH, perceived muscle pain and the decrease in countermovement. It is confirmed that a women’s soccer match produced an increase of resting muscle oxygenation in 24 h after the official match.

Inactive forearm muscle oxygenation has been reported to begin decreasing from the respiratory compensation point (RCP) during ramp leg cycling. From the RCP, hyperventilation occurs with a decrease in arterial CO2 pressure (PaCO2). The aim of this study was to determine which of these two factors, hyperventilation or decrease in PaCO2, is related to a decrease in inactive biceps brachii muscle oxygenation during leg cycling. Each subject (n = 7) performed a 6-min two-step leg cycling. The exercise intensity in the first step (3 min) was halfway between the ventilatory threshold and RCP (170+/-21 watts), while that in the second step (3 min) was halfway between the RCP and peak oxygen uptake (240+/-28 watts). The amount of hyperventilation and PaCO2 were calculated from gas parameters. The average cross correlation function in seven subjects between inactive muscle oxygenation and amount of hyperventilation showed a negative peak at the time shift of zero (r = -0.72, p<0.001), while that between inactive muscle oxygenation and calculated PaCO2 showed no peak near the time shift of zero. Thus, we concluded that decrease in oxygenation in inactive arm muscle is closely coupled with increase in the amount of hyperventilation.

The measurement of resting muscle oxygenation capacity is under investigation in team sports. The aim of the current study was to observe the changes after a preseason, in muscle oxygen saturation (SmO2) at rest and the relationship with body composition and jump power in soccer players. 17 soccer players (age 21.8 ± 2.2 years) were enrolled. Body composition, somatotype, countermovement jump (CMJ) and single-leg countermovement jump (SLCMJ) were evaluated. Also, SmO2 at rest in the gastrocnemius muscle using the technique of arterial occlusion in the dominant leg and non-dominant leg was performed. All measurements were made before and after the preseason. The t-student test, Pearson’s correlation and inter-individual response of the subject’s statistic were applied to measure the magnitudes of change and the effect size. An inverse relationship was observed between SmO2 at the initial-occlusion (r= -0.82), final-occlusion (r= -0.79) and SmO2 recovery (r= -0.82) with the SLCMJ power. A moderate relationship was also observed between oxygen consumption and fat mass (r= 0.64). The measurement of SmO2 at rest can be considered as a possible performance parameter because it has determined its relationship with the ability to produce strength and jumping power in soccer players. === La medición de la capacidad de oxigenación del músculo en reposo está bajo investigación en los deportes de equipo. El objetivo del presente estudio fue observar los cambios, después de una pretemporada, en la saturación de oxígeno muscular (SmO2) en reposo y la relación con la composición corporal y la potencia de salto en los jugadores de fútbol. Participaron 17 jugadores de fútbol (edad 21.8 ± 2.2 años). Se evaluó la composición corporal, el somatotipo, el salto de contramovimiento (CMJ) y el salto de contramovimiento de una sola pierna (SLCMJ). Simultáneamente, se midió la SmO2 en reposo en el músculo gastrocnemio utilizando la técnica de oclusión arterial en la pierna dominante y no dominante. Todas las mediciones se realizaron antes y después de la pretemporada. Se aplico la prueba t-student, la correlación de Pearson y la estadística de respuesta inter-individual de los sujetos para medir las magnitudes de cambio y el tamaño del efecto. Se observó una relación inversa entre SmO2 en la oclusión inicial (r= -0.82), la oclusión final (r= -0.79) y la recuperación de SmO2 (r= -0.82) con la potencia SLCMJ. También se observó una relación moderada entre el consumo de oxígeno y la masa grasa (r=0.64). La medición de SmO2 en reposo se puede considerar como un posible parámetro de rendimiento, porque se identificó su relación con la capacidad de producir fuerza y potencia de salto en jugadores de fútbol.
