This study assessed the intra-individual reliability of oxygen saturation in intercostal muscles (SmO2-m.intercostales) during an incremental maximal treadmill exercise by using portable NIRS devices a test-retest study. Fifteen marathon runners (age, 24.9 ± 2.0 years; body mass index, 21.6 2.3 kg·m−2; V̇O2-peak, 63.7 5.9 mL·kg−1·min−1) were tested on two separate days, with 7-day interval between measurements. Oxygen consumption (V̇O2) was breath-by-breath method V̇O2-test, while SmO2...
The purpose of this study was to determine the association between functionality as assessed by 6-minute walking test (6MWT), maximal voluntary contraction quadriceps (MVCQ), and thickness echo intensity measured sonography, in patients with chronic obstructive pulmonary disease (COPD).Maximal rectus femoris vastus intermedius were evaluated 20 COPD. Functionality 6MWT. Differences muscles determined Student t test. Pearson Spearman rank correlation coefficients used analyze relationships...
Respiratory muscle training (RMT) improves physical performance, although it is still debated whether this effect depends on the type of training. The purpose study was to compare effects two different types RMT, i.e., voluntary isocapnic hyperpnea (VIH) and inspiratory threshold loading (ITL), deoxygenation intercostal (ΔSmO2-m. intercostales) vastus lateralis lateralis) muscles during exercise. Twenty-four participants performed eight weeks RMT by: (i) VIH (3 days·week-1 for 12 min at 60%...
The study aimed to evaluate the association between changes in ventilatory variables (tidal volume (Vt), respiratory rate (RR) and lung ventilation (V.E)) deoxygenation of m.intescostales (∆SmO2-m.intercostales) during a maximal incremental exercise 19 male high-level competitive marathon runners. oxygen consumption (V.O2) were recorded breath-by-breath by exhaled gas analysis. A near-infrared spectroscopy device (MOXY®) located right-hemithorax allowed recording SmO2-m.intercostales. To...
This study aimed to evaluate if the changes in oxygen saturation levels at intercostal muscles (SmO2-m.intercostales) assessed by near-infrared spectroscopy (NIRS) using a wearable device could determine respiratory compensation point (RCP) during exercise. Fifteen healthy competitive triathletes (eight males; 29 ± 6 years; height 167.6 25.6 cm; weight 69.2 9.4 kg; V˙O2-máx 58.4 8.1 mL·kg−1·min−1) were evaluated cycle ergometer maximal oxygen-uptake test (V˙O2-máx), while lung ventilation...
This study aimed to examine sex differences in oxygen saturation respiratory (SmO 2 - m.intercostales ) and locomotor muscles m.vastus lateralis while performing physical exercise.

Little is known about the effects of training load on exercise-induced plasma increase interleukin-6 (IL-6) and soluble IL-6 receptor (sIL-6R) their relationship with vascular remodeling. We sought to evaluate role sIL 6R as a regulator IL-6-induced Forty-four male marathon runners were recruited allocated into two groups: low-training (LT, &lt;100 km/week) high-training (HT, ≥100 km/week), 22 athletes per group. Twenty-one sedentary participants used reference. IL-6, sIL-6R sgp130...
Introduction: An increased risk of atrial fibrillation (AF) has been demonstrated in high-performance athletes. Soluble vascular adhesion molecule-1 (sVCAM-1), a biomarker involved inflammation and cardiac remodeling, is associated with the development AF general population. However, relationship between sVCAM-1 left (LA) remodeling poorly investigated long-distance runners (LDR). Aim: To determine association LA levels LDR during training period before marathon race. Methods: Thirty-six...
Ventilatory thresholds (VTs) are key physiological parameters used to evaluate physical performance and determine aerobic anaerobic transitions during exercise. Current assessment of these requires ergospirometry, limiting evaluation laboratory or clinical settings. In this work, we introduce a wearable respiratory system that continuously tracks breathing exercise estimates VTs ramp tests. We validate the rate predictions in 17 healthy adults using ergospirometry analysis. addition, use 107...
The gold standard to assess the aerobic capacity in physically active subjects and athletes is maximal oxygen consumption test (VO2-max), which involves analysis of exhaled-gases cardiorespiratory variables obtained via breath-by-breath method an ergospirometer during incremental exercise. However, this cannot elucidate metabolic changes at muscular level. Near-infrared spectroscopy (NIRS) has emerged as a valuable technology evaluate local levels (Tissular Saturation Index, TSI) by...
Exercise increases the cost of breathing (COB) due to increased lung ventilation (V˙E), inducing respiratory muscles deoxygenation (∇SmO2), while increase in workload implies ∇SmO2 locomotor muscles. This phenomenon has been proposed as a leading cause exercise intolerance, especially clinical contexts. The use high-flow nasal cannula (HFNC) during routines rehabilitation programs gained significant interest because it is therapeutic intervention for reducing symptoms associated with such...
