| Summary: | The measurement of resting muscle oxygenation capa city 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 |
