Figure 4.

Graphs and top five node results obtained by complex network analysis using the Pagerank metric in exercise scenarios without inspiratory muscle pre-activation (Scenario AO30, at Panel A) and with inspiratory muscle pre-activation (Scenario IM_PA + AO30, at Panel B). Graph visualizations were done using Gephi software (version 0.9.2, Paris, France). Legend: AO30 = all-out 30 s, IM_PA = inspiratory muscle pre-activation, Hgt = height, BM = body mass, %BF = percentual of body fat, MIP = maximal inspiratory pressure, SI = global strength index of inspiratory muscles, Lac = blood lactate, HR = heart rate, SpO₂ = arterial oxygen saturation, RPE = perceived exertion, O₂Hb = oxyhemoglobin relative concentration, HHb = deoxyhemoglobin relative concentration, tHb = total hemoglobin, TSI = tissue saturation index. Abbreviations accompanied by p, m, min and D represent peak, mean, minimum and delta (between the final and initial results), respectively. Abbreviations accompanied by BB and VL represent the results in the biceps brachii and vastus lateralis, respectively.
