Jem Arnold is a physiotherapist, coach and PhD student. Currently, his main research focus is investigating FLIA: blood flow limitation of the iliac artery, a condition that affects certain athletes even at the very elite level, sometimes with surgery as the end outcome. Jem is also very involved and knowledgeable in using NIRS (near-infrared spectroscopy) to measure muscle oxygen saturation (SmO2). We dive deep into how using NIRS and SmO2 can inform workout execution as well as training interventions and athlete profiling. IN THIS EPISODE YOU'LL LEARN ABOUT: -What is NIRS and what is muscle oxygen saturation? -The balance of oxygen delivery (to the capillaries surrounding muscle tissue - supply) and extraction (by the muscles from the capillaries - demand) -NIRS testing protocols, and how it relates (and does not relate) to oxygen uptake (VO2) and lactate measurments -Using NIRS to profile athletes -Using NIRS in high-intensity workouts to optimise interval execution -Blood flow limitation of the iliac artery (FLIA) - what is it, and what is its prevalence among athletes -Risk factors for FLIA -Current detection and diagnosis methods of FLIA, as well as treatment options -How Jem's research aims to find methods by which FLIA detection can be improved SHOWNOTES: https://scientifictriathlon.com/tts358/ SCIENTIFIC TRIATHLON AND THAT TRIATHLON SHOW WEBPAGE: www.scientifictriathlon.com/podcast/ SPONSORS: ROKA - Exceptional quality triathlon wetsuits, trisuits, swimskins, goggles, performance sunglasses as well as prescription eyeglasses and sunglasses.

Daniel Muniz, PhD, is a senior lecturer at the University of Hertfordshire. Some of his recent work involves big data analysis (from Strava) of marathon runners, where Daniel and his co-authors set out to explore how decoupling (changes in the ratio of internal to external workload, like heart rate to pace) can be an important parameter in marathon (and possibly broader endurance) performance. IN THIS EPISODE YOU'LL LEARN ABOUT: -What does decoupling mean and how can it be calculated? -How a lesser degree of decoupling is associated with better marathon performance -What are the physiological underpinnings of decoupling? -What do we know about training interventions to reduce decoupling? -Is decoupling independent of other markers of performance (like Critical Speed) or can it be improved by improving more traditional markers of performance? -Using big data from Strava to calculate Critical Speed based on training data only SHOWNOTES: https://scientifictriathlon.com/tts343/ SCIENTIFIC TRIATHLON AND THAT TRIATHLON SHOW WEBPAGE: www.scientifictriathlon.com/podcast/ SPONSORS: ROKA - Exceptional quality triathlon wetsuits, trisuits, swimskins, goggles, performance sunglasses as well as prescription eyeglasses and sunglasses.

IN THIS EPISODE YOU'LL LEARN ABOUT: -VLaMax: the background, reason for recent surge to popularity, and the mechanistic and practical issues with measuring it -Polarised training is not optimal for endurance athletes: the arguments against polarised training being an "ideal" training intensity distribution, and why quantifying training intensity distributions may not be the smartest thing to do in the first place -How measures of complexity (e.g. Approximate entropy ApEn, alpha-exponent of Detrended Fluctuation analysis DFA) can be used to assess fatigue, and the potential applications thereof SHOWNOTES: https://scientifictriathlon.com/tts331/ SCIENTIFIC TRIATHLON AND THAT TRIATHLON SHOW WEBPAGE: www.scientifictriathlon.com/podcast/ SPONSORS: Precision Fuel & Hydration - Optimise and individualise your fueling and hydration strategy using the free online Sweat Test and Quick Carb Calculator on precisionfuelandhydration.com.
