“…Due to safety reasons, the current standardized training programs addressed either to healthy individuals, clinical patients, and athletes require the controversial quantification of the relative exercise intensity (Jamnick et al, 2020). And, accordingly, the use of ergometers and strength machines.…”

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.

“…Furthermore, the only outcome of the test is an approximation of the VȮ2max, based on the distance achieved, without taking cognisance of the average speed maintained during the test, nor the heart rate response throughout the test. Therefore, the utility of the test for programme prescription is limited based on the fact that prescribing intensities as a percentage of VȮ2max is not considered a valid method for exercise prescription on the basis that this leads to substantial heterogenous homeostatic responses both in and across individuals [9]. The utility of the test for evaluating field-sport athletes may also questionable on the basis that no changes of direction are incorporated into the test.…”

“…Although first developed in the early 20 th century, and despite nuanced variations in stage gradations and durations, the essence of the test has remained intact for almost 100 years [8]. While the GXT is considered the gold standard, it exhibits several limitations in that it (i) fails to scale, (ii) shows methodological variability, (iii) is costly, (iv) requires substantial expertise, and (v) possibly lacks ecological validity for field-based sports [9]. Based on these limitations the need for valid and reliable field-based testing was borne, leading to the subsequent development of several methodologically grouped tests such as:…”

The overarching purpose of this review was to highlight the utility of different aerobic field tests in terms of the parameters they provide, with a specific focus on shuttle running and all-out testing. Various field tests are discussed in detail and are categorised according to linear continuous running tests (e.g. 12-minute Cooper Test, University of Montreal Track Test [UMTT], 1200/1600 m time trials, 3-minute all-out test for running [3MT]), intermittent shuttle running tests (e.g. yo-yo inter-mittent recovery test level 1 [YYIR1], 30-15 intermittent fitness test [IFT], and the intermittent all-out shuttle test [IAOST]), and continuous shuttle running tests (e.g. 1.2 km shuttle run test [1.2SRT], maximal multi-stage 20-m shuttle test [MSR], 25-m, 30 m and 50-m 3-minute all-out shuttle test [AOST]). Readers will be guided through the theoretical and practical underpinnings of the 3MT methodology, where the all-out testing methodology is stationed within the testing paradigm, and how to practically implement and interpret the results thereof.

“…However, given between-subjects variability in the ranges defining each exercise intensity domain (i.e. moderate, heavy and severe), the fixed-percentage approach do not adequately control the metabolic stimulus during exercise (Iannetta et al, 2020;Jamnick et al, 2020). So, a model that considers the exercise intensity domains for exercise prescription is recommended.…”

“…There is little evidence, with the exception of critical power (CP) or critical speed (CS), to support the validity of most commonly used methods (i.e., maximal lactate steady state, respiratory compensation point, and second ventilatory threshold) to demarcate the boundary between the heavy and severe-intensity domains (Jamnick et al, 2020;Jones et al, 2019;Galán-Rioja et al, 2020). Identifying this maximal oxidative metabolic rate, represented by CS is very useful so it provides a marker around which exercise intensity can be prescribed (Jones & Vanhatalo, 2017;Poole et al, 2016;Vanhatalo et al, 2011).…”

We assessed the reliability and validity of a 10-min submaximal treadmill test (T10) to predict critical speed (CS). Forty-two runners completed a familiarization trial plus two experimental trials (T10 test and T10 retest). Reliability between the T10 test and T10 retest was assessed using coefficient of variation (CoV), limits of agreement (LoA) and intraclass correlation (ICC). For validity, the speed from the T10 retest was compared with the CS determined from 3 runs on separate days on a running track over 1200, 2400, and 3600 m (field test). Reliability between the T10 test and T10 retest showed a CoV of 3.4%, LoA of 0.05 ± 0.39 m.s −1 , and an ICC of 0.93. Validity showed that speed (m.s −1) (T10 retest: 3.86 ± 0.51; field test: 3.88 ± 0.55) did not differ between trials. The T10 retest was highly correlated with the field test, r = 0.93, and the standard error for the estimate of CS using the T10 retest was 0.06 m.s −1 , and the LoA was 0.02 ± 0.40 m.s −1. A submaximal 10-min treadmill test (T10) provides a practical and accessible method to estimate CS.
