Recovery bout intensity of HIIT – Active or Passive?
As proposed on HIIT Science, programming for high-intensity interval training (HIIT) can contain up to 12 important variables that can be manipulated to adjust the physiological response of a HIIT Session (Figure 1). Of those 12 variables, work interval intensity,...
Why Athletica?
I’ve previously written about my “semi-pro” days as a young triathlete in the late 80s and early 90s, and love reflecting on the fitness that was gifted to me in those days (I miss it). To show my age, this was in fact before the internet was part of daily life. For the latest happenings in our sport we went to Triathlete Magazine, which I read religiously each month, cover-to-cover.
Should athletes run downhill?
Introduction Downhill running sections are a natural part of off-road (e.g. cross-country, trail or ultramarathon running) and road running races (e.g. the St. George marathon, the Holualoa Tuscon marathon, the Big Sur International marathon). However, downhill...
Athletica, is hiring!
In line with our nearing launch and need to scale rapidly, we’re expanding our small but exceptional team at Athletica. The purpose of Athletica is to apply the evolving HIIT Science principles for athletes and coaches across as many sports as possible using advances...
Using Repeated Sprints In The Football Codes
Repeated-sprint training (RST) is a unique and attractive HIIT format for preparing football code athletes, such as soccer, rugby union, rugby 7s and rugby league players, for competition.
HIIT and thermal imaging – military tech meets sports science
From my great grandfather to today, nearly half of my family has worked for the Spanish Army and NATO. Being raised in the military, I’ve always been amazed by the cutting-edge technology they develop. Technologies we take for granted today to monitor training loads...
Neuromuscular load and HIIT: new insights from the foot
The popularity of high-intensity interval training (HIIT), which consists primarily of repeated short to long bursts of high-intensity exercise, continues to soar because its effectiveness and efficiency have been proven in use by both elite athletes and general...
Individual adaptation and HRV in elite triathletes during altitude training
Preamble We became aware that the study described in this blog might not see the light of day for various reasons. Due to its novelty (world class athletes, field-based testing, etc.), we invited Marco to publish his data here on our HIIT Science Blog and in SPSR, as...
Muscle fibre typology and the individual responses to training – Part II
Background In part I of our blog, we discussed the application of a non-invasive method to estimate the ratio of slow (type I) and fast (type II) muscle fibres — a concept termed muscle fibre typology. We’ve used this technique to characterize the muscle fibre make-up...

Saludos compañeros entusiastas del entrenamiento en intervalos de alta intensidad (HIIT), y bienvenidos a nuestro blog, llamado: “Obtenga su HIIT”. Aquí, le brindaremos contenido relacionado con la ciencia y la aplicación de HIIT, el tema principal de HIIT Science.
Muscle fibre typology and the individual response to training – Part I
Recently, we had the opportunity to collaborate with a large group of colleagues on some projects aiming to understand more about the individual responses to training
HIIT Science in Gaelic Football Part-1: Sport Description and Game Demands
Sport description and running demands Gaelic football is one of the national sports of Ireland (1, 2). The sport is played both on an intra- and inter-county basis among the counties of Ireland (6, 7, 9). Match-play consists of two teams of 15 players composed of a...
