1/ 💥 @shane_maloneIRL & @mart1buch have just published work that cannot go under the radar #SportsScience

2/ Building on work in muscle fibre typology 💪—e.g. Type I dominance ➡️ faster recovery (@eline_lievens et al. 2020) & overreaching risks in Type II profiles (@Phil_Bellinger et al. 2020)—their work links variability in training dose-response (D-R) to physiological profiles 🧬

1/ Interval training is a cornerstone of endurance performance. We often stick to stock standard session design, but new research highlights various manipulations to maximise the adaptive stimulus, from interval duration & intensity to recovery dynamics. #HIIT #SportsScience 🧵👇 2/ Before diving in, it's essential that all training, including interval training, first addresses the critical performance determinants of the sport & event; underpinned by first principles understanding of the unique requirements 🧑‍🔬👇

1/ Sports Scientists often criticise how other sports train. We hear things like "why do swimmers train such huge volumes compared to runners racing similar durations?" It’s not just coaching tradition & culture; it's about physiological & biomechanical demands 🧵👇#SportsScience 2/ Races of similar durations should stress the body similarly, right? Not exactly. Rates of force development, cadence, and duty cycles differ significantly across sports, shaping muscle recruitment & fatigue development. This changes everything 🏃‍♂️🏊‍♂️🚴‍♂️

I want to bust a common #Cycling myth 💥
That spinning at high cadences is "more aerobic," shifting power from the muscles to the cardiovascular system, thus ⬇️ fatigue & ⬆️ performance. But science tells a different story. Let's break down the evidence. #CyclingScience 🚴🧵👇 Higher cadences recruit MORE fast-twitch (Type II) muscle fibres 🦵 than lower cadences. These fibres are less oxidative, more glycolytic, and less efficient, increasing energy costs and anaerobic metabolism - not reducing muscular involvement 📉

Early in my career working with elite Sprint Kayakers in the London 2012 Olympic cycle, I noticed a pattern: some athletes improved rapidly, whilst others on the same training program - similar age, experience, calibre - stagnated. Same training, different results. But why? 🧵👇 Athletic performance at the highest level is complex. Years of training build adaptations to enhance performance. Principles like progressive overload, periodization, and specificity guide our training philosophies and approaches.
