Prescribing the frequency, duration, or volume of training is simple as these factors can be
altered by manipulating the number of exercise sessions per week, the duration of each …

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 …

High-intensity interval training (HIIT) has garnered attention because of the promise that it
may confer health benefits with reduced time commitment compared to prescriptions calling …

The use of personal records (PRs) for running different distances may be used to derive
critical speed (CS) and the finite capacity for running speeds exceeding CS (D′). Using CS …

The aim of this study was to examine the impacts on blood lactate concentration, measured
heart rate and assessment of perceived exertion during split sessions of equal relative load …

How parameters derived from oxygen uptake V˙ O 2 kinetics relate to critical speed is not
fully understood, and how such parameters relate to more sport-specific performances, such …

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

We investigated the validity of a recently developed equation for predicting sprinting times of
various tactical loads based upon the performance of a running 3-min all-out exercise test …

Tactical professionals often depend on their physical ability and fitness to perform and
complete occupational tasks to successfully provide public services or survive on the …

Training is a complex, multi-factorial process, which involves the manipulation of the
duration, frequency and intensity of exercise. When quantifying the physiological and …
