The anaerobic threshold (AT) remains a widely recognized, and contentious, concept in
exercise physiology and medicine. As conceived by Karlman Wasserman, the AT coalesced …

New Findings What is the topic of this review? Biological and methodological factors
associated with the variable changes in cardiorespiratory fitness in response to endurance …

Responses to exercise at a given percentage of one's maximum rate of oxygen consumption
(V̇o2max), or percentage of the power associated with V̇o2max during a graded exercise …

The ability to predict the systematic decrease of power during physical exertion gives
valuable insights into health, performance, and injury. This review surveys the research of …

Background In the last decades, marathon running has become a popular form of physical
activity among people around the world. It should be noticed that the main marathon races …

Critical power represents an important parameter of aerobic function and is the highest
average effort that can be sustained for a period of time without fatigue. Critical power is …

Purpose Improvements in D′(the fatigability constant for running) subsequent to training
interventions remain elusive. High-intensity interval training (HIIT) within the severe intensity …

There has been a recent proliferation of original research articles, reviews, letters, and
perspectives debating the suitability and interchangeability of several exercise thresholds …

Purpose This study aimed to determine how the speed-distance relationship, described by
critical speed (CS) and distance prime (D'), is altered with aging. Methods Official race data …

Purpose Two parameters in particular span both health and performance; critical speed (CS)
and finite distance capacity (D′). The purpose of the present study was to:(1) classify …
