“…In line with these findings, a recent study showed that cyclists have greater CRC strength compared to sedentary individuals (Abreu et al, 2022b). Moreover, this difference was identified only when non-linear approaches were applied to compute the CRC, such as joint symbolic analysis (Abreu et al, 2022a). In addition, an increase in CRC was detected during exposure to intense aerobic exercise under hypoxic situations (Uryumtsev et al, 2020).…”

“…The strength of CRC varies in athletes when compared to age-matched sedentary individuals, both at rest and during stressful stimulus (Abreu et al, 2022a). A study conducted with recreational cyclists, who trained for at least 6 uninterrupted months, at least 150 min a week, showed greater CRC strength during spontaneous breathing at rest and after orthostatic stress (i.e., active postural maneuver), when compared to individuals who did not perform any exercise (Abreu et al, 2022b).…”

“…Therefore, computing the CRC by considering at least a bivariate approach that includes the recording of respiratory signal might favor a more genuine measure of CRC. In addition to greater CRC strength, amateur cyclists also had lower respiratory rate values when compared to sedentary individuals at rest and during orthostatic stress, thus suggesting that respiration exerts an important influence on the regulation of spontaneous cardiovascular dynamics, as well as during stressful stimuli (Abreu et al, 2022a).…”

“…The computation of the CRC indexes seems to be useful in the sports medicine and is strongly affected by physical exercises. There is a hypothesis that the increase in CRC is associated with efficiency of gas exchange by matching pulmonary perfusion to ventilation during inspiration, which may be associated with higher VO 2peak values, since VO 2peak is determined in part by a great efficiency in gas exchange (Dick et al, 2014;Hayano and Yuda, 2019;Abreu et al, 2022a). For example, it is known that RSA increases after a high-intensity training period in runners (de Meersman, 1992) and cyclists (Al-Ani et al, 1996), alongside a significant increase in VO 2peak .…”

The estimation of cardiorespiratory coupling (CRC) is attracting interest in sports physiology as an important tool to characterize cardiac neural regulation genuinely driven by respiration. When applied in sports medicine, cardiorespiratory coupling measurements can provide information on the effects of training, pre-competition stress, as well as cardiovascular adjustments during stressful stimuli. Furthermore, since the cardiorespiratory coupling is strongly affected by physical activity, the study of the cardiorespiratory coupling can guide the application of specific training methods to optimize the coupling between autonomic activity and heart with possible effects on performance. However, a consensus about the physiological mechanisms, as well as methodological gold standard methods to quantify the cardiorespiratory coupling, has not been reached yet, thus limiting its application in experimental settings. This review supports the relevance of assessing cardiorespiratory coupling in the sports medicine, examines the possible physiological mechanisms involved, and lists a series of methodological approaches. cardiorespiratory coupling strength seems to be increased in athletes when compared to sedentary subjects, in addition to being associated with positive physiological outcomes, such as a possible better interaction of neural subsystems to cope with stressful stimuli. Moreover, cardiorespiratory coupling seems to be influenced by specific training modalities, such as inspiratory muscle training. However, the impact of cardiorespiratory coupling on sports performance still needs to be better explored through ad hoc physical exercise tests and protocols. In addition, this review stresses that several bivariate and multivariate methods have been proposed to assess cardiorespiratory coupling, thus opening new possibilities in estimating cardiorespiratory interactions in athletes.
