High-intensity interval training (HIT), in a variety of forms, is today one of the most effective
means of improving cardiorespiratory and metabolic function and, in turn, the physical …

Abstract Short-duration sprints (< 10 seconds), interspersed with brief recoveries (< 60
seconds), are common during most team and racket sports. Therefore, the ability to recover …

Background Since the introduction (in 2006) of commercially available portable wireless
muscle oximeters, the use of muscle near-infrared spectroscopy (NIRS) technology is …

While intermittent hypoxic training (IHT) has been reported to evoke cellular responses via
hypoxia inducible factors (HIFs) but without substantial performance benefits in endurance …

This study examined the occurrence and nature of repeated-sprint sequences (RSS) in
highly-trained young soccer players, as a function of age, playing position and playing time …

This study investigated the influence of 180 changes of direction during a repeated-sprint
running test on performance, cardiorespiratory variables, muscle deoxygenation and post …

Background Repeated-sprint training (RST) involves maximal-effort, short-duration sprints
(≤ 10 s) interspersed with brief recovery periods (≤ 60 s). Knowledge about the acute …

Purpose: The aim of the current study was to compare the effects of speed/agility (S/A)
training with sprint interval training (SIT) on acceleration and repeated sprint ability (RSA) in …

Purpose: The purpose of this study was to evaluate changes in autonomic control of heart
rate (HR) and fitness in a group of elite soccer players during the preseason. Methods: Eight …

The study examined the influence of cerebral (prefrontal cortex) and muscle (vastus
lateralis) oxygenation on the ability to perform repeated, cycling sprints. Thirteen team-sport …
