    Freediving and the dive reflex: how we conserve oxygen with Prof Erika Schagatay

    What adaptations allow humans to freedive to extraordinary depths, and what might this reveal about our evolutionary past? In this episode of The Progress Theory, I’m joined by Professor Erika Schagatay, a biologist and environmental physiologist who’s published over 100 papers on freediving. We explore not only the remarkable feats of breath-hold diving, but also the physiological and evolutionary mechanisms that make them possible. We discuss how freedivers are able to go beyond what textbooks used to describe as human limits, the unique features of populations who depend on diving for survival, and Erika’s research suggesting that humans may have developed aquatic adaptations before becoming distance runners. We get into the details of bone density, spleen size and blood redistribution, plus the risks and thresholds involved in pushing human records today. Whether you’re interested in human evolution, the physiology of performance, or practical implications for training in other extreme environments, this conversation offers plenty to think about. In this episode, we discuss:00:00 – Introduction and why understanding freediving matters 01:54 – Erika’s background: from Arctic Sweden to the Bajau divers 05:05 – Evolutionary theories: were we “divers before runners”? 08:43 – Human physiological changes enabling breath-hold diving 10:36 – The role of bone density and buoyancy in foraging depth 13:26 – The diving response: oxygen prioritisation and vasoconstriction 15:21 – Freediving world records: what are the current limits? 17:23 – Popularity of freediving and predicting human potential 20:07 – Categories of freediving and why “No Limits” isn’t a sport 24:43 – What No Limits diving reveals about physiology (and dangers) 29:48 – The challenge of marginal gains at the elite level 31:41 – Nitrogen narcosis: what is it and its effects at depth 34:05 – Differences between seals and humans in lung compression 36:13 – Training for lung flexibility, blood shift and mouthfill techniques 41:29 – Overlap between freediving adaptations and altitude performance 45:00 – Possibilities for cross-training: can breath-hold training help mountaineers? 46:32 – Research funding and the future of mechanistic studies 48:23 – Where to find Erika’s research and how to get in touch TakeawaysEvolution and aquatic adaptations: Erika Schagatay argues that our ancestors may have developed diving abilities and shallow-water foraging adaptations—such as increased bone density and oxygen-conserving reflexes—before becoming efficient terrestrial endurance runners. This challenges traditional views of human evolution.Limits of human freediving: Physiological features like the diving reflex (vasoconstriction and prioritising blood flow to the brain), spleen contraction and skeletal structure play central roles in freediving performance. Modern freedivers approach predicted human depth and time records not through sudden breakthroughs, but through tiny, hard-won gains and extraordinary specialisation.Freediving and hypoxic training for other sports: The same adaptations that benefit freedivers—such as spleen enlargement and enhanced blood oxygenation—may also be advantageous at high altitude. Breath-hold or apnea training could potentially support mountaineers and endurance athletes, but more research is needed to quantify these effects.

    Altitude sickness: the warning signs you shouldn't ignore with Monica Piris

    What actually happens to your body on a high-altitude expedition, and how much do genetics, experience, or fitness matter when the summit is in the “death zone”? In this episode of The Progress Theory, I’m joined by Dr Monica Piris, a medical doctor and veteran of dozens of Himalayan expeditions, to understand the physiological and practical challenges of climbing above 5,000 metres. We explore how the body adapts (or fails to adapt) to extreme altitude, why altitude illnesses can escalate rapidly, and what individual, genetic and cultural differences mean for mountaineers. Monica describes the day-to-day realities of her role as an expedition doctor, from remote preparation through managing clients at base camp, and offers clear advice for anyone considering a serious mountain challenge. Along the way, we discuss why technical difficulty and fitness interact with altitude risk, the realities of using supplemental oxygen, and what motivates climbers to keep pushing despite the hazards. Whether you’re preparing for an expedition or fascinated by how humans cope in extreme environments, Monica’s experience and practical insights will help you understand the real trade-offs behind altitude performance. In this episode, we discuss:00:00 – The risks of extreme altitude and Monica’s background as an expedition doctor 03:28 – Common illnesses on expeditions and the realities of “glamorous” mountain medicine 04:46 – How Monica works with clients before and during expeditions 07:17 – Why doctors stay at base camp and the impact of altitude on decision-making 08:39 – What altitude does to the body: definitions and oxygen availability 10:26 – Adaptation limits above 6,000 metres and the variability in acclimatisation 12:16 – Genetics, cultural adaptation, and why some populations perform better at altitude 14:10 – Recognising and responding to high-altitude illnesses (AMS, HACE, HAPE) 18:28 – How quickly altitude illnesses can progress and the importance of self-awareness 20:14 – Managing motivation, communication and decision-making on expeditions 23:35 – Why Monica rarely faces dramatic resistance from clients 24:29 – Differences between commercial clients and professional athletes 28:22 – The distinction between elite performance and guided expedition support 30:24 – Using and not using supplemental oxygen: safety, ethics, and challenges 33:58 – Is Everest technical, or just high? What makes mountains dangerous 36:45 – How technical difficulty, fitness, and exertion affect risk at altitude 39:53 – Preparing physically and practically for mountaineering challenges 41:35 – The rise of extreme challenges and social media influence 42:11 – FKTs and what elite athletes actually need from doctors 44:29 – The reality of appetite, nutrition and fuelling at serious altitude 49:51 – Monica’s personal altitude symptoms and inter-individual differences 52:30 – Why even professionals sometimes turn around on major climbs 53:38 – Variability in individual response and the role of trip factors 55:51 – Why concurrent illness increases risk at altitude 57:07 – How to contact Monica and find out more about safe expeditions TakeawaysAltitude adaptation and risk are highly individual and context-dependent: Monica explains that physiological responses to altitude differ greatly due to genetics, previous exposure and training, and even the presence of minor illnesses or fatigue.Recognising and acting on altitude illness early is crucial: Symptoms such as headache, nausea, reduced exercise capacity and cough may seem minor at first but can escalate rapidly. Education and honest self-monitoring are key to safety on expeditions above 5,000 metres.Preparation goes beyond fitness — practical mountain experience matters: Monica emphasises that good preparation includes time spent moving in mountainous terrain, carrying loads, dealing with cold and logistical discomforts, and not just aerobic fitness. Those with practical exposure are much less likely to be overwhelmed when conditions become extreme.

    Altitude training: how to prepare for high-altitude challenges with James Barber

    How do you prepare for the world’s toughest mountain challenges, especially as more people attempt rapid ascents, high-altitude marathons, or unique endurance feats at elevation? Whether you’re a seasoned climber or planning your first trek, getting acclimatisation right can be the difference between a successful adventure and a dangerous one. I’m joined by James Barber, altitude specialist and Lead Performance Specialist at the Altitude Centre in London. We explore the science and practical application of altitude preparation: why acclimatising for 6,000 to 6,500 metres is the priority, how training protocols are adapted for increasingly ambitious or unconventional events, and why you do not need to be an elite athlete to benefit from targeted altitude exposure. We discuss the physiological adaptations that support performance and recovery at altitude, such as changes in blood oxygen saturation and breathing patterns, and look at how these approaches change for rapid ascents, ultra-endurance, and high-altitude marathons. If you’re interested in the real details of altitude training, from basecamp to summit and everything in between, this episode will help you understand the key methods and decisions involved. In this episode, we discuss:00:00 – Is the appetite for extreme altitude challenges growing? 02:00 – James’s background and the Altitude Centre’s story 05:31 – Who trains at the Altitude Centre? From elite teams to first-time mountaineers 06:44 – Testing, training, and tailoring protocols for different ambitions 09:11 – Typical progression towards Everest and multi-year preparation 11:05 – Simulating altitude: equipment capabilities and limitations 13:19 – Why acclimatising for "summit" altitudes isn’t always the goal 16:12 – Measuring and interpreting physiological adaptation at altitude 17:29 – Red blood cells, sleep tents, and when additional adaptation is needed 18:57 – Rapid ascents (flash expeditions) and when the approach must change 21:07 – Recent and emerging extreme events: Everest in 7 days, high-altitude base jumps, world’s highest marathons 24:40 – Preparing for endurance races and marathons at high elevation 26:32 – Key differences between trekking and racing at altitude 28:24 – Designing and progressing altitude training plans 30:58 – Climbing with or without supplemental oxygen: does the strategy change? 32:49 – How soon to begin: timelines and customising pre-acclimatisation 34:13 – How to connect with James and the Altitude Centre TakeawaysPre-acclimatisation is for everyone, not just elites: As James Barber explains, most Altitude Centre clients are ordinary people preparing for challenging treks or endurance events. Careful testing and personalised plans can help anyone maximise both safety and enjoyment.The goal is sufficient altitude adaptation, not just maximum exposure: Acclimatisation typically aims to help people feel comfortable at 6,000 to 6,500 metres, focusing on basecamp levels rather than preparing for long periods at the highest altitudes. This approach helps make the final ascent safer and more manageable.Training protocols adjust to the challenge: Rapid ascents and extreme events require a higher standard of pre-acclimatisation. In these cases, combinations of active hypoxic sessions and sleep tents may be necessary, while standard protocols are usually suitable for slower treks.

    VO2 max: are you training the wrong limiter? | Evan Peikon

    What does it really mean to train your “energy systems”—and how should you approach improving your weakest link? Many programmes talk about “conditioning”, but how do you know if you’re targeting the mechanism that matters most for your goals? In this episode, I’m joined by physiologist and CrossFit coach Evan Peikon to explore how recent advances in technology and research can help athletes and coaches make smarter decisions. We discuss how the outdated view of energy systems as isolated, sequential contributors to performance can lead to mistakes in training design. Evan shares what he’s learned updating his book Paradigm Shift, especially on identifying performance “limiters” in athletes—whether respiratory, delivery, or utilisation—and tailoring training accordingly. We also look at how practical tools like NIRS (near-infrared spectroscopy) can clarify what’s truly holding someone back, even for those without access to lab equipment. Whether you coach hybrid athletes or just want to better understand how to personalise your own training, you’ll find this conversation challenges assumptions and brings clarity to complex questions. In this episode, we discuss:00:00 – Opening and welcome in the new studio 00:11 – Introduction to Evan Peikon and his background 01:20 – Evan’s recent exit from Nox and current work in biotech and academic research 02:54 – Evan’s PhD focus on precision oncology and biodefence 04:14 – How skills transfer between human performance, medicine and technology 05:39 – Evan’s aims after completing his PhD 06:21 – Startups, academia, and the changing research landscape 07:31 – Why Evan returned to human performance and updated Paradigm Shift 09:23 – How his thinking on energy systems and control mechanisms has evolved 12:29 – Technology advances and making complex data more accessible 13:24 – The gap between wearable data and useful training decisions 15:20 – Types of physiological “limiters”: utilisation, delivery, respiratory 19:45 – How these limiters appear in different sports and athlete levels 24:27 – Impact of sport programming and selection pressures 26:56 – Interval training examples for different limiter archetypes 33:21 – Integrating limiter-based training into the overall training plan 36:58 – Real-world examples: adjusting perceived “muscular endurance” limitations 40:40 – Identifying limiter types without advanced technology 47:38 – Structural signs, posture, and their relation to true limitations 51:02 – Using NIRS data to inform programming: recovery, volume, and progression 56:49 – Why repeating effective sessions can be more useful than constant novelty 58:54 – Evan’s current work and how to find more resources TakeawaysNot all energy system “limitations” are created equal: Evan Peikon explains how an athlete’s performance may be limited by different physiological systems—muscular (utilisation), cardiovascular (delivery), or respiratory. Identifying these distinctions is critical: the problem is rarely just “conditioning” and the wrong focus can waste training effort.Interval structure and training adaptations depend on individual constraints: The same session can produce different results depending on a person’s limiting system. Coaches should tailor pacing, rest, and exercise order—sometimes using simple tools like performance curves or pulse oximeters—to address the root cause of underperformance.New technology aids, but practical interpretation still matters: While affordable wearables and NIRS sensors now provide more data than ever, Evan emphasises that progress comes from understanding trends and context, not chasing isolated metrics. Repeating and adjusting useful sessions, not constantly changing workouts, often yields better insights and adaptations.

Kult Media The Science of Hybrid Training It was originally thought that you could not effectively train for both strength and endurance at the same time because they required different adaptations which were not compatible with each other. It was claimed that ‘an interference effect’, blunted the adaptations for strength if you simultaneously trained for endurance. However, recent developments in sports which require both strength and endurance have really challenged this idea, with hybrid athletes producing impressive performances in both strength and endurance sports together. This had led scientists, coaches, and athletes to rethink what is humanly possible and suggests the interference effect is not as influential as originally thought. But what is a hybrid athlete?

    Maximise performance using NIRS with Jem Arnold

    Welcome to another episode of The Progress Theory, where we explore the latest scientific principles to help you optimise your performance. In this episode, Dr Phil Price sits down with Jem Arnold—a physiologist, physiotherapist, and PhD candidate at the University of British Columbia with a fascinating dual focus on high-performance sport and clinical research. Jem’s work dives deep into individual responses to training and the use of Near Infrared Spectroscopy (NIRS), a cutting-edge wearable technology that measures muscle oxygenation both in the lab and out in the real world. In this episode, Jem breaks down what NIRS is, how it works, and why its ability to capture local muscle oxygenation is so useful for endurance athletes, hybrid competitors, and anyone interested in interpreting the body’s signals during exercise. Drawing from both his research and personal experience with vascular conditions affecting elite cyclists, Jem shares insights on programming, individual variability, and how blending subjective feedback with objective tech can revolutionise our approach to training. Whether you’re curious about the next frontier of monitoring tools, want to understand performance plateaus, or just love to geek out on physiology, you’ll find plenty to stimulate your thinking in this conversation. As always, don’t forget to follow The Progress Theory for more episodes and resources. Let’s dive in!

Individual Variability is Key: Jem emphasised that group-level sports science research doesn’t always translate directly to individual athletes. NIRS can help tailor interventions and programming by capturing each athlete’s unique response, especially when combined with subjective reports. Practical Application Requires Context: Having all the gadgets is great, but Jem highlighted the importance of integrating NIRS data with athlete sensations, performance metrics, and expert guidance. It’s about turning data into tailored, actionable information—don’t let the numbers overwhelm the athlete or the process!

    Unlock Peak Performance with Plyometrics with Matt McInnes-Watson

    Hello and welcome to the Progress Theory where we discuss scientific principles for optimising human performance. In this episode, we're joined by plyometric expert Matt McInnis-Watson. Now I don't know if you've noticed, but you quite often hear of a new world record being broken in a number of different sports, say, weightlifting or quite often in running. I'm always hearing of a new world record in, say, 5k, 10k, etcetera, etcetera. But you rarely hear of a world record being broken in a jump event such as the long jump or triple jump or high jump. I mean, Jonathan Edwards' world record in the triple jump has been going since 1995. So what needs to happen in jump training and the culture within jump training to see an improvement in jump sports? That's why I contacted Matt. And if you have any interest in improving jump performance, this episode is for you. In this episode, we discuss: 1:02 - Introduction3:35 - The importance of Plyometrics in today’s society and longevity8:35 -  Issues with plyometric research13:44 - People get the plyometric definition wrong - still16:12 - different types of plyometrics 20:27 - Why are jump world records rare?25:57 - Strength specificity30:25 - What needs to change?35:10 - Which jump sports will see the biggest changes over the next few years?39:08 - Power athlete vs speed athlete44:13 - The importance of supramaximal50:37 - Plyometric recommendations Takeaways🔹 Plyometrics for Health Longevity: Plyometrics aren't just for athletes. They play a crucial role in maintaining reactive strength, which is vital for reducing injury risks, especially as we age. Matt highlighted how integrating plyometrics can aid in preserving dynamic capacity, thus enhancing long-term health. 🔹 The Science and Research of Plyometrics: It was fascinating to hear about Matt's critique of current plyometric research. He underscored the need for clearer definitions and proper visual documentation in studies to better understand plyometric movements and their implications for training. 🔹 Training for Future Success: A pivotal point was the shifting focus towards speed training in events like high jump and triple jump. By restructuring training to incorporate more dynamic and reflexive elements rather than solely focusing on strength, we can push the boundaries of human performance in these fields.

Kult Media The Science of Hybrid Training It was originally thought that you could not effectively train for both strength and endurance at the same time because they required different adaptations which were not compatible with each other. It was claimed that ‘an interference effect’, blunted the adaptations for strength if you simultaneously trained for endurance. However, recent developments in sports which require both strength and endurance have really challenged this idea, with hybrid athletes producing impressive performances in both strength and endurance sports together. This had led scientists, coaches, and athletes to rethink what is humanly possible and suggests the interference effect is not as influential as originally thought. But what is a hybrid athlete? What is the ‘interference effect’? And how can we maximize our training to improve at the same time our strength and endurance performance? In this book, Dr Phil Price provides insight into the misconceptions surrounding strength and endurance training by distilling the past 50 years of research and drawing on the conversations he had with great scientists, coaches, and athletes on The Progress Theory podcast. This book is essential reading for hybrid athletes and coaches who are looking to understand the key training variables and their effect on the simultaneous development of strength and endurance performance.
