MUSCLE OXYGENATION OF THE QUADRICEPS AND GASTROCNEMIUS DURING MAXIMAL AEROBIC EFFORT

ABSTRACT Introduction: Near infrared spectroscopy (NIRS) is a non-invasive technique that used in the assessment of tissue oxygenation and monitoring physical activity. Objective: To determine influence sexual, anthropometric ergospirometric factors on muscle quadriceps gastrocnemius, obtained by NIRS during stress test. Methods: Twenty healthy subjects participated this study (10 women). Two Humon Hex® devices were placed dominant side gastrocnemius muscles to measure oxygen saturation (SmO2). The test was performed treadmill with electrocardiographic control measurement consumption. SmO2 at rest after maximum effort In addition, height, weight, skinfold waist contour measured. Bioimpedance obtain percentages fat mass mass, which calculate relative (RFM). Results: both higher males than females. At effort, similar groups. positively related body percentage contour, negatively fat, RFM thickness. negative correlation between more evident It observed variables quantify are not values, except for HR max males. Conclusion: recreational athletes influenced location device subjects. biggest differences sexes muscle. Level Evidence II; Diagnostic Studies - Investigating Test .
