“…Thus, years ago these authors suggested as a possible future direction the association of the muscle oxygenation measurement with other physiological responses monitored during tests and training (for example, HR and blood lactate concentration). Recently, this way has been accomplished and some studies aimed to adopt these recommendations 16,18 .…”

“…For this, two PortaMon devices (Artinis Medical Systems BV, Zetten, Netherlands) including three light source transmitters (each one with two wavelengths between 750 and 850 nm) at 30, 35, and 40 mm distance to the receiver, were used to determine the tissue saturation index (TSI, %). These devices were also used to obtained the changes in the oxyhemoglobin ([O 2 Hb]), These NIRS devices were positioned on two right muscles: the biceps brachii (BB), in medial biceps brachii portion 14,42,43 , an upper limb muscle considered as less active during running exercise, and the vastus lateralis belly (VL), 15 cm above the proximal edge of the patella and 5 cm towards the external side 44,45 parallel to the long axis of the muscle 19 considered more active during running effort 16,46 .The equipment was wrapped tightly in a transparent plastic to avoid humidity and which created a waterproof barrier 13 , and by a dark band, to secure the probe and protect it from environmental light.…”

“…The signal was captured at 10 Hz. After signal capture, the data were smoothed using the 10 th order lowpass-zero phase Butterworth filter (cut-off frequency 0.1 Hz) 16 Heart rate, arterial oxygen saturation and blood lactate concentration. Heart rate was continuously recorded every 1 second by a heart rate monitor (Polar V800, Finland).…”

“…Most investigations involving power efforts and muscle oxygenation analysis during high-intensity exercises were performed on a cycle ergometer [12][13][14][15] and in repeated sprint 13,16,17 but with measurements conducted in one muscle group 16,18 or in independent exercise to compare arm vs leg oxygen responses 13 . Rissanen et al 19 performed simultaneous analysis in biceps brachii and vastus lateralis in incremental treadmill running, observing differences between less and more active muscle oxygenation, especially in severe-intensity exercise.…”

“…NIRS is a non-invasive method that has been shown to be a significant tool capable of estimating the muscle oxygenation events, such as variations in oxyhemoglobin (O 2 Hb), deoxyhemoglobin (HHb), total hemoglobin (tHb) and tissue saturation index (TSI) in skeletal muscle 30,31 . This technique based on optical principles has been commonly used in clinical studies involving pathologies and exercise prescription 32,33 and recently focused on inactive participants 12 , active subjects 34,35 and athletes 16,[36][37][38] to improve the knowledge about physiological and performance responses. In a recent systematic review, Perrey and Ferrari 39 suggested that the popularity of muscle oxygenation studies in exercise increased after the commercialization of portable wireless muscle oximeters.…”

High-intensity exercises including tethered efforts are commonly used in training programs for athletes, active and even sedentary individuals. Despite this, the knowledge about the external and internal load during and after this effort is scarce. Our study aimed to characterize the kinetics of mechanical and physiological responses in all-out 30 seconds (AO30) tethered running and up to 18 minutes of passive recovery. Additionally, in an innovative way, we investigated the muscle oxygenation in more or less active muscles (vastus lateralis and biceps brachii, respectively) during and after high-intensity tethered running by near-infrared spectroscopy-NIRS. Twelve physically active young men were submitted to AO30 on a non-motorized treadmill to determine the running force, velocity and power. We used wearable technologies to monitor the muscle oxygenation and heart rate responses during rest, exercise and passive recovery. Blood lactate concentration and arterial oxygen saturation were also measured. In a synchronized analysis by high capture frequency of mechanical and physiological signals, we advance the understanding of AO30 tethered running. Muscle oxygenation responses showed rapid adjustments (both, during and after AO30) in a tissue-dependence manner, with very low tissue saturation index observed in biceps brachii during exercise when compared to vastus lateralis. Significant correlations between peak and mean blood lactate with biceps brachii oxygenation indicate an important participation of less active muscle during and after high-intensity AO30 tethered running. Physical exercise performed at different intensities promotes distinct physiological responses during both activity and recovery process 1,2. High-intensity and short-volume efforts are widely used in the sports context and have also been extensively adopted in non-athlete training programs, such as high-intensity interval training (HIIT) and sprint interval training 3,4. In the same way, high-intensity tethered exercises (including resisted sled sprinting) performed maximally have been applied to improve physical and athletic performances 5,6. Despite that, there is a lack of knowledge about the mechanical and physiological kinetics during all-out tethered exercise and recovery. This gap can compromise the training load interpretation when this type of effort is adopted. Training load is described as external and internal, depending on which measurements of the athlete/participant are assessed 7. External load is defined as the amount and quality of work performed (e.g. distance covered, velocity and exercise power). On the other hand, the internal load indicates the physiological and psychophysiological responses of the organism to the effort imposed from the external load. However, internal-load indicators, especially during exercise, and the integration of external and internal loads need to be improved 7. Most exercise and recovery studies investigate systemic responses to the observed internal load, such as heart rate and blood lactat...
