“…As nonlinear and history-dependent systems, physiological networks present hysteresis, a phenomenon that explains the delay in a system's recovery of its initial state after a perturbation (Hristovski et al, , 2014Montull et al, 2020). The study of this phenomenon, a hallmark of complex systems, has revealed the limitations of the widely used linear and proportional regulation models in Exercise Physiology (Abrantes et al, 2012), and has shown the excessively simplified assumptions and artificially created contexts (e.g., in fitness testing).…”

“…The same exercise perturbation (external load) does not have the same impact (internal load; Fullagar et al, 2019), depending on the previous exercise, the state of the network, and other contextual differences. The area of hysteresis has recently been pinpointed as a new non-invasive marker of exercise stress and tolerance to test the state of the network (Montull et al, 2020).…”

“…In contrast, the exploration of different features of the network dynamics like stability, instability, critical phenomena (enhancement of fluctuations and critical slowing down), or hysteresis behavior (Hristovski et al, 2014) may provide a rich information about the personal (in space and time) adaptive and qualitative fitness state. These features have been already tested during exercise using kinematic and psychophysiological variables (see Balagué et al, 2014aBalagué et al, , 2015Garcia-Retortillo et al, 2015;Slapsinskaite et al, 2016;Vázquez et al, 2016;Montull et al, 2020) and the approach should be enlarged to physiological data.…”

The basic theoretical assumptions of Exercise Physiology and its research directions, strongly influenced by reductionism, may hamper the full potential of basic science investigations, and various practical applications to sports performance and exercise as medicine. The aim of this perspective and programmatic article is to: (i) revise the current paradigm of Exercise Physiology and related research on the basis of principles and empirical findings in the new emerging field of Network Physiology and Complex Systems Science; (ii) initiate a new area in Exercise and Sport Science, Network Physiology of Exercise (NPE), with focus on basic laws of interactions and principles of coordination and integration among diverse physiological systems across spatio-temporal scales (from the sub-cellular level to the entire organism), to understand how physiological states and functions emerge, and to improve the efficacy of exercise in health and sport performance; and (iii) to create a forum for developing new research methodologies applicable to the new NPE field, to infer and quantify nonlinear dynamic forms of coupling among diverse systems and establish basic principles of coordination and network organization of physiological systems. Here, we present a programmatic approach for future research directions and potential practical applications. By focusing on research efforts to improve the knowledge about nested dynamics of vertical network interactions, and particularly, the horizontal integration of key organ systems during exercise, NPE may enrich Basic Physiology and diverse fields like Exercise and Sports Physiology, Sports Medicine, Sports Rehabilitation, Sport Science or Training Science and improve the understanding of diverse exercise-related phenomena such as sports performance, fatigue, overtraining, or sport injuries.

“…For example, in a stepwise or ramp task whereby absolute demands increase up to a point, and then following this reverse (i.e. the absolute task demands decrease symmetrically), on the latter stage the perception of effort is higher than during the former due to the residual drop in capacity that occurred (Montull et al, 2020). 73 Wright et al (2018) also appear to allude to this equivalency, albeit not explicitly.…”

What is (perception of) effort? Objective and subjective effort during attempted task performance

Despite its apparent intuitiveness and widespread interest from across various fields, ‘effort’ is a variable that seems difficult to define. The purpose of this article is to consider and define ‘effort’ during task performance. In doing so I argue for a distinction between the actual effort (objective effort) required, and the perception of that effort (subjective effort), during intentional performance of tasks. I adopt a set theoretical approach to defining both actual and perceived effort as both constructs and concepts. Further, I aim to present discussion and definitions that are agnostic of the specific task demands being performed (i.e. physical, cognitive, self-control, or a combination of task demands) Throughout, I attempt to draw on and synthesise thoughts and ideas from across a multitude of disciplines (though note that this is not intended to be an exhaustive interdisciplinary review), engage in considerable armchair philosophising, and also offer what small insights I have from my own experience both as someone experiencing ‘effort’, and as a third-person observer investigating it. This work is intended to, at the very least, make my own current conceptualisation and understanding of ‘effort’ transparent to other researchers and aid in the interpretation of any subsequent empirical work on the topic. Further, I hope that it might be of use to researchers from the various fields interested in this topic, and assist in fostering opportunities for integration of learnings across disciplines. I hope that this work will allow for further understanding of the role of ‘effort’ and its perception from a broad scientific perspective.
