The Progress Theory

Hello and welcome to The Progress Theory where we discuss how to implement scientific principles to optimise human performance. I’m Dr Phil Price and on today’s episode, we have Professor Louis Passfield, sports scientist and physiologist from the University of Calgary.

Cycling, despite being a huge sport in itself, has gained popularity within the hybrid training community. Many are choosing cycling as the endurance sport they want to develop in while aiming to increase strength simultaneously. So, what are the determinants of cycling performance? Well, in this episode Professor Passfield and I discuss the use of different metrics, such as heart rate and power, for tracking cycling performance, what is cycling efficiency, and tips on how to improve your cycling performance.

But before we get to the show I want to thank our sponsors, who the show would not be possible without.

I want to take a moment to express my gratitude to my production partner, KULT Media. 

KULT Media has been instrumental in the development & success of the progress theory. 

They have created brand guides, comprehensive podcast strategies, enhanced the podcast production, developed custom workflows for me and edited & mixed all of the video, audio and social media content. 

Their simple Coach, Create & Collaborate process has saved me 100’s hours in podcast production, resolved countless technical issues and consistently help me to improve my podcasting game. 

So if you want to establish and engage your audience, or are ready to launch your own podcast head to www.kult.media to learn more. 

Thank you to HMN24 – fuelling human potential and optimising everyday human performance and well-being. 

First of all – HMN24 is not a sports supplement company. I’ve seen sport supplements be used as a method to improve performance in the gym and at a certain sport. However, these supplements, like a pre-workout, are often used on top of a lifestyle which does not provide the foundation needed for optimal performance. There’s no point taking pre-workout supplements if your sleep, hydration, and nutrition is an unstructured mess. I’m convinced that a large percentage of injuries are often caused, not because training was poor, but because a poor lifestyle foundation increased the athlete’s susceptibility to injury. Sports supplements are often used to plaster the cracks in poor lifestyle habits, which only causes more future problems. 

And this is where HMN24 is different. The product range at HMN24 not only helps improve your foundation; it optimises it. The HMN24 products are designed to fit around your circadian rhythms, from the moment you wake up, to key moments in the day when you need optimal focus, to getting the best sleep at night, there’s a product to optimise each phase of the day.

I can’t recommend enough the “live on form’ pack, consisting of the products Rise, flow and pre-sleep. Rise is for the morning and is my absolute favourite. It tastes amazing. Rise contains caffeine for increased morning alertness (though not a huge amount of caffeine, which is sooo much better for avoiding gastro-intestinal distress), electrolytes from coconut and watermelon powder to increase hydration after the previous night’s sleep, and B-vitamins, to ensure you ready to win the morning. I’m not a fan of long-winded morning routines. I wake up, have my Rise with ice, and get straight to writing, and I’ve seen such an improvement in getting into deep work.

By the time 2pm comes around the effects of caffeine from Rise has worn off, but I don’t want to take more caffeine because that’s going to interrupt getting to sleep later on. This is where Flow is perfect. It’s a caffeine-free nootropic, perfect for improving alertness and concentration during that mid-afternoon slump. And finally, I take pre-sleep just before bed, which is a comprehensive night-time complex, formulated to help support well-being and fortify the body against the fatigue and stress that come with leading a performance-driven lifestyle. 

I can’t recommend these products enough they are a game changer for human performance. And also, while you’re at their website hmn24.com check out there plant protein, which is incredible for smoothies post-training, and their website includes articles and an awesome podcast for those wanting to learn more about human performance.

Hello and welcome to The Progress Theory where we discuss how to implement scientific principles to optimise human performance. I’m Dr Phil Price and on today’s episode we have British Olympic weightlifter and World and European silver medalist, Sarah Davies.

Weightlifting is a technical sport which requires years of dedication to master the skill of the lifts and develop the necessary strength to move heavy loads quickly. In this episode, Sarah Davies takes us through her weightlifting journey which has culminated in her competing at the Tokyo Olympics, and achieving silver medals at both the 2021 European and World championships. And she is just getting started. She details what training has led to her success, how to break down weightlifting skill learning, and how going to a max lift every-time you train may be negatively affecting your development.

Hello and welcome to The Progress Theory where we discuss how to implement scientific principles to optimise human performance. I’m Dr Phil Price and on today’s episode we have Powerlifting coach, Mike Tuchscherer.

When training for strength and endurance simultaneously, the body is put under so much stress from different types of stimuli that it is hard to plan programming so far in advance. Training has to be autoregulated to account for variations in how we respond to these different stimuli. In this episode, Mike and I discuss the use of a subjective measure like a rating of perceived exertion (RPE) for programming strength training, and how it can be utilized to account for the different ways athletes respond to strength training.

Hello and welcome to The Progress Theory where we discuss how to implement scientific principles to optimise human performance. I’m Dr Phil Price and on today’s episode, we have the Gains Fairy himself, Dr Pak, Strength coach, researcher, and university lecturer at Southampton Solent. 

When training for both strength and endurance simultaneously we need to make sure that we are not training too much to cause an unrecoverable amount of fatigue. We don’t need those junk running miles or those unnecessary work sets. We want to do just enough that will increase performance without affecting our other training. But how do we know if we’re doing too much? This is where Dr Pak comes in as in this episode we discuss the minimum dose effect for strength training.

Hello and welcome to The Progress Theory where we discuss how to implement scientific principles to optimise human performance. I’m Dr Phil Price and on today’s episode we have Dr Matt Lee, Postdoctoral Research Fellow at the Institute for Health and Sport, at Victoria University in Melbourne.

It was originally thought that you couldn't develop strength and endurance simultaneously due to something called the interference effect. Certain molecular, hormonal and neuromuscular adaptations occur which may limit your strength training progress if you also do a large amount of endurance work, for example. However, it’s not as simple as that, and there are many factors, like training intensity and recovery time between sessions, which we can manipulate to minimise the interference effect. Dr Matt Lee specialises in concurrent training research and in this episode we discuss how the interference effect was discovered, what training factors can blunt adaptations, and what you can do to train strength and endurance simultaneously. 

But before we get to the show I want to thank our sponsors, who the show would not be possible without.

I want to take a moment to express my gratitude to my production partner, KULT Media.

In this episode, we discuss:

• 1:30 - Introduction
• 9:18 - What is concurrent training and the interference effect? The work of Robert Hickson
• 15:32 - The interference effect on different strength parameters
• 19:44 - Neuromuscular and molecular effects
• 27:57 - How the research supports the amazing feats of hybrid training seen today
• 33:54 - The effect of previous training on the interference effect
• 42:34 - Effect of volume and frequency on the interference effect
• 49:32 - minimum dose to minimise the interference effect

Thank you to Matt for coming onto The Progress Theory and talking about his research on concurrent training and the interference effect. It was awesome to get an understanding around where the misconceptions of the interference effect have come from and dive into the literature to show that this effect may not be as prominent as history tells us. 

I just wanted to provide some final thoughts on key areas which really stood out to me.

Firstly, Matt’s discussion around the molecular responses to specific training and our training history really made me think. If the molecular response to training decreases as we become more familiar with that training, surely training regularly at both strength and endurance disciplines would reduce the molecular responses and reduce the severity of the interference effect? Does this mean that with an appropriate hybrid training programme the interference effect, if there is one, should decrease over time?

And secondly, Matt highlighted that a training frequency of 3 sessions a week is enough to create improvement but doesn’t increase the volume to such an extent that it could increase the chance of the interference effect? So, as an example, If we trained strength 3 times a week and endurance 3 times a week, all on separate days, the interference effect should barely exist. You’re training enough and getting sufficient rest in between sessions for the interference effect to not affect training at all.

Anyways I hope you enjoyed this episode and it allowed you to start thinking about your hybrid programming. If you want further information on this topic I definitely recommend checking out Matt’s research, we’ve created a link for it in the show notes. If you enjoyed the show It would be awesome if you could leave us a review and share this episode on your insta story. Feed that algorithm to help the show grow. We’ll see you in the next one.

Hello and welcome to The Progress Theory where we discuss how to implement scientific principles to optimise human performance. I’m Dr Phil Price and on today’s episode we have Hybrid athlete and coach at Omnia Performance, Fergus Crawley.

I’ve been watching Fergus’ youtube channel over the past year and have really enjoyed how he has pushed the boundaries of human performance. Despite previous misconceptions around training for strength and endurance simultaneously, he has shown you can hit impressive numbers in the weight room while still being able to run ultramarathons. Enjoy this episode as Fergus discusses his accomplishments, how performing huge physical challenges has allowed him to redefine what is hard, and how he organizes his hybrid training. And If you’re interested in performing in multiple sports, then this is the episode for you.

But before we get to the show I want to thank our sponsors, who the show would not be possible without.

The HMN24 products are designed to fit around your circadian rhythms, from the moment you wake up, to key moments in the day when you need optimal focus, to getting the best sleep at night, there’s a product to optimise each phase of the day.

I can’t recommend enough the “live on form’ pack, consisting of the products Rise, flow and pre-sleep. Rise is for the morning and is my absolute favourite. It tastes amazing. Rise contains caffeine for increased morning alertness (though not a huge amount of caffeine, which is sooo much better for avoiding gastro-intestinal distress), electrolytes from coconut and watermelon powder to increase hydration after the previous night’s sleep, and B-vitamins, to ensure you ready to win the morning. I’m not a fan of long-winded morning routines. I wake up, have my Rise with ice, and get straight to writing, and I’ve seen such an improvement in getting into deep work.

By the time 2pm comes around the effects of caffeine from Rise has worn off, but I don’t want to take more caffeine because that’s going to interrupt getting to sleep later on. This is where Flow is perfect. It’s a caffeine-free nootropic, perfect for improving alertness and concentration during that mid-afternoon slump. And finally, I take pre-sleep just before bed, which is a comprehensive night-time complex, formulated to help support well-being and fortify the body against the fatigue and stress that come with leading a performance-driven lifestyle. 

I can’t recommend these products enough they are a game changer for human performance. And also, while you’re at their website hmn24.com check out there plant protein, which is incredible for smoothies post-training, and their website includes articles and an awesome podcast for those wanting to learn more about human performance. You can even check out the episode I did with them, I thoroughly enjoyed that chat I had with Phi Learney, Co-founder of HMN24, and it has led to an awesome collaboration with HMN24 supporting The Progress Theory.

Thank you to Fergus for coming onto The Progress Theory and talking about his amazing hybrid achievements and his ideas around hybrid programming, which you can find more about at Omnia Performance, so check out their website and instagram, it is all in the show notes. Because of Fergus, Hybrid training is growing in popularity, especially hybrid training for a strength sport such as powerlifting, and an endurance sport like triathlon, and I honestly think it could develop into a recognised sport. You’ve heard it here first.

I just wanted to provide some final thoughts on key areas which really stood out to me.

Firstly, I completely agree that the best recovery is a well-organised training programme. This is particularly essential for hybrid training as you’re having to consolidate two sports into one programme; you’re not adding two training programmes together. How Fergus described the progression of high-intensity and interval work, into threshold work, into long, low-intensity work, over the training week, really fascinated me as it made sense. You're working on physical qualities, and each section gives the body stress to adapt to while providing physiological processes which help recover from the previous training.

Secondly, I like the aim of developing work capacity slowly, so the progression is quite linear. The idea around developing efficiency by increasing tolerance to stress by building volume up slowly makes sense to me. You need to give your body time to adapt to these stresses, so programming a very slow and linear progression not only gives your body that time to adapt but also reduces any unnecessary spikes in volume which could lead to injury.

Anyways I hope you enjoyed this episode and it has sparked some ideas on what physical challenges you can take on. If you could train for a huge challenge, what would it be? Use the principles Fergus outlined in this episode to find the best way to train for it. I’d definitely recommend heading to his youtube channel for some inspiration.

Hello and welcome to The Progress Theory where we discuss how to implement scientific principles to optimise human performance.

I’m Dr Phil Price and It’s the start of season 5. In this season, we’re focusing on how you can develop strength and endurance simultaneously, so we’ll be talking to expert scientists, coaches and athletes in the worlds of strength, endurance and hybrid training. 

So let’s get season 5 off to a start. In today’s episode we are joined by S&C coach, hybrid athlete and co-host of season 2 of The Progress Theory, who also took part in the concurrent training challenge in 2020, Daryl Green. Here we will go over what we learned from training for strength and a marathon simultaneously, our 2022 hybrid goals, and Daryl’s programming tips for making 2022 your year of the hybrid athlete.

But before we get to the show I want to thank our sponsors, who the show would not be possible without.

I want to take a moment to express my gratitude to my production partner, KULT Media. 

KULT Media has been instrumental in the development & success of the progress theory. 

They have created brand guides, comprehensive podcast strategies, enhanced the podcast production, developed custom workflows for me and edited & mixed all of the video, audio and social media content. 

Their simple Coach, Create & Collaborate process has saved me 100’s hours in podcast production, resolved countless technical issues and consistently help me to improve my podcasting game. 

So if you want to establish and engage your audience, or are ready to launch your own podcast head to www.kult.media to learn more. 

Thank you to HMN24 – fuelling human potential and optimising everyday human performance and well-being. 

First of all – HMN24 is not a sports supplement company. I’ve seen sport supplements be used as a method to improve performance in the gym and at a certain sport. However, these supplements, like a pre-workout, are often used on top of a lifestyle which does not provide the foundation needed for optimal performance. There’s no point taking pre-workout supplements if your sleep, hydration, and nutrition is an unstructured mess. I’m convinced that a large percentage of injuries are often caused, not because training was poor, but because a poor lifestyle foundation increased the athlete’s susceptibility to injury. Sports supplements are often used to plaster the cracks in poor lifestyle habits, which only causes more future problems. 

And this is where HMN24 is different. The product range at HMN24 not only helps improve your foundation; it optimises it. The HMN24 products are designed to fit around your circadian rhythms, from the moment you wake up, to key moments in the day when you need optimal focus, to getting the best sleep at night, there’s a product to optimise each phase of the day.

Hello and welcome to The Progress Theory where we discuss how to implement scientific principles to optimise human performance. On today’s episode we have S&C coach and performance nutritionist at Omnia Performance, Jonny Pain.

Training as a generalist or hybrid training has become very popular in recent years. More people don’t want to just train for a specific sport; they want to be good at multiple sports, to be really strong yet also have the ability to run a marathon. Jonny has been coaching athletes training multiple disciplines for the last 15 years and has recently set up Omnia Performance where he provides coaching and programming for the concurrent development of strength and endurance. In this episode, we discuss the true meaning of hybrid training, how training for strength and endurance can co-exist, and how to structure your training week to ensure peak performance and maximum recovery.

In this episode, we discuss:

• 2:22 - An introduction to Jonny Pain and Omnia Performance
• 6:40 - The History of Omnia Performance
• 10:41 - Working with Alex Viada
• 12:48 - The growth of Hybrid Training
• 23:16 - Hybrid training for big challenges like the Celtman
• 26:40 - consolidation of stressors over a microcycle
• 32:13 - understand non-training stressors for programming
• 36:28- How Omnia Performance Auto-regulate their programming
• 40:42 - How to contact Omnia Performance
• 42:16 - Jonny’s experience with Project Vertical

Thank you to Jonny for coming onto The Progress Theory and talking about his work with Omnia Performance and his ideas around hybrid training. Hybrid training is getting more popular as people are starting to see that with an appropriate training programme we don’t necessarily have to be excellent in only one training domain.

I just wanted to provide some final thoughts on key areas which really stood out to me.

Firstly, I enjoyed hearing his ideas around what a hybrid athlete is. To me, it seemed like his definition of a hybrid athlete wasn’t necessarily someone that was great at everything. It’s borne out of an understanding that developing multiple qualities is essential to enhance the training you're trying to specialise in. IT seems counterintuitive to only train in one domain as having a base layer of multiple physical qualities actually improves performance in your speciality.

Secondly, I like his auto-regulated microcycle approach to programming. When juggling so many variables it is essential to know how the athlete is feeling very regularly. This type of training needs a very close working relationship between coach and athlete as it is hard to predict in advance how the athlete is going to react to so many stressors. So how can you programme that far ahead? You need a rough guide in your head of the direction you want to go and the training needed to get there, but how you get there has to be heavily auto-regulated based on the athlete

Anyways I hope you enjoyed this episode and it has sparked some ideas on what challenge you will take on. Could you train strength and ultra endurance concurrently? I think, with the right coaching and programming, you’ll be surprised what you can achieve. But first, check out Omnia Performance, all the links from the show are below.

Hello and welcome to The Progress Theory where we discuss how to implement scientific principles to optimise human performance. On this episode, we have S&C and sprint coach, David Sadkin.

There’s a reason why the 100m sprint final at the Olympics is one of the highlights of every Olympic games. Seeing the fastest athletes in the world reach speeds only a handful of people can reach is awesome. However, Sprinting is more than just running as fast as possible. It takes the right blend of physical qualities, technique and competitive drive to reach our sprint potential. So how do you train to achieve this? In this episode, David and I discuss variations in sprint technique, David’s training philosophy for coaching sprinters, and common mistakes athletes make when training to get faster.

In this episode, we discuss:

• 1:22 - An introduction to David Sadkin and how he uses social media
• 5:21 - How David got into Sprint coaching
• 11:47 - Sprint mechanics and what to look for
• 14:43 - Examples of coaching based on a technical issue
• 17:13 - Misconceptions with ‘high knees’
• 18:53 - The use of wickets versus coaching cues
• 22:14 - Testing Stride Frequency and stride length
• 26:51 - David’s S&C philosophy
• 30:04 - common mistakes in S&C for sprinters
• 35:48 - Are we focusing too much on lifting heavy?
• 37:30 - David’s future plans/goals
• 38:10 - Recommendations for aspiring sprint coaches

Thank you to David for coming onto The Progress Theory and talking about his experience within the S&C community and his work with his sprint athletes. He has a great story of an injured athlete who fell in love with a new sport and wanted to know everything about it, and it has led him to become an incredibly successful sprint coach.

I just wanted to provide some final thoughts on key areas which really stood out to me.

Firstly, I really enjoyed hearing how open his approach to both coaching sprinting and S&C was. He isn’t constricted to a certain way of doing things. He knows every sprinter requires different training to ensure they progress, so he tries to understand them as an athlete before making a decision on what training they require. He doesn’t try to fit them into his way of doing things, he fits his own ideas based on the athlete themselves.

And secondly, he clearly works well within a system for his athletes. His training and coaching decisions come from discussions with the osteopath and physio he works with, his understanding of the science around the determinants of sprint performance, and his own ideas. Again, it is this openness and adaptability to his coaching that allows him to utilise all of the information available and ultimately make the right training programme.

Anyways I hope you enjoyed this episode and it sparked your interest in sprinting. I truly believe learning about sprinting transfers so well into other areas of human performance so this really created some ideas for me to reflect on.

In this episode, we have environmental physiologist and lecturer at Bournemouth University, Dr Becky Neal.

Environmental physiology is fascinating as it's so interesting what happens to the human body when competing in extreme environments. Exercise in the heat is particularly interesting as it is a common factor that can greatly influence performance, particularly those who competed at the Tokyo Olympics, where it was reported to be very hot and humid. In this episode, Becky and I discuss the body’s physiological responses to heat, what can lead to heat injury or illness, and what strategies you can use to acclimate to the heat and improve sporting performance.

In this episode, we discuss:

• 2:44 - An introduction to Dr Becky Neal
• 5:20 - How the Body physiologically responds to heat
• 8:27 - Factors influencing how the body reacts to heat
• 10:43 - The difference between hot and humid
• 14:02 - Strategies to acclimate and acclimatise to the heat
• 17:13 - acclimatisation strategies for different events
• 19:32 - The use of heat chambers in preparation for an event
• 24:26 - Is the heat often underestimated?
• 30:30 - Heat injury and illness
• 34:01 - Thermal tolerance
• 37:24 - Differences between men and women
• 42:40 - Becky’s choice of guest for the Progress Theory

Thank you Becky for coming onto The Progress Theory and talking about her ideas and research on how the heat affects us during exercise and what training we can do to improve our thermoregulation. I think we’ve all seen videos where the heat has greatly affected athletes to the point of injury and you see them reduced to a crawl, so it was great to get insight into all the factors which can influence how heat and humidity affect us during exercise.

I just wanted to provide some final thoughts on key areas which really stood out to me.

Firstly, it was amazing to see just how many different factors influence the effect of the heat, particularly that the heat influences different sports in different ways. In cycling, the wind resistance will directly help your body cool, whereas, during running, this is greatly reduced. We need to understand all the factors which will affect athletes during their sport and then understand how environmental conditions such as heat may influence the specifics of the sport.

Secondly, I thought it was interesting that the effect of many cooling strategies can influence the body in negative ways if used inappropriately. For example, an ice vest will be great to cool the body during a run, but also covering the body in this way will hamper the skin’s ability to evaporate sweat. There must be an appropriate length of time to use an ice vest before it becomes counterproductive.

Anyways I hope you enjoyed this episode and it allowed you to reflect on your next race or challenge. What environmental factors will you face? Will heat be one of them. If so, I hope this episode provided you with plenty of information to help develop your own acclimatisation strategies.
