Announcement Related to the Rest of the 2022 - Irregular Publishing Schedule
Dear listeners,
So it happened that both of the podcast hosts became parents on the very same day!
Recordings have been swapped to diaper changing and lullaby singing. This means that the Meaningful Sport Series will be paused until about the end of the year.
Regular episodes and Practitioner`s Viewpoint Series will be running but with less episodes. Some of the popular episodes will be republished from earlier days of the podcast.
Thanks for your understanding and we hope that the over 400 episodes so far will provide something to listen to meanwhile. We are enthusiastic about the podcast and grateful for all the positive feedback and support, it really makes our day. While we scale back we would still appreciate all your feedback and suggestions on who and what you would like to hear in the podcast as it will be returning to full swing next year.
Have a great autumn all,
Noora and Olli

Many athletes believe that they should be self-critical and hard on themselves to reach their full potential. Yet, what if an opposite perspective, focused on self-compassion, would actually be much more conducive to flourishing and meaningful experiences in sport? These and other questions are explored in this episode with Dr Leah Ferguson.
Questions explored in this podcast include:
- What is self-compassion and how is it different from self-esteem?
- What is eudaimonic well-being? How is meaning related to that?
- Is sport culture resistant to self-compassion? Should we talk about it with a different language?

Opportunities for involvement in sports in later life have increased significantly and many sports around the globe have competitions and categories for Masters/Veteran athletes. At the same time, researchers have explored the experiences and meanings of being an older athlete, showing tensions in individual experiences as well as in shifting social discourse surrounding sport and ageing. We have shifted from ageing-as-decline to active ageing discourses, which provide different imagination of growing old. But are there also some darker sides in the shift towards more positive visions of ageing?
Rylee Dionigi is a professor in of Sport and Exercise Science at Charles Sturt University with expertise in qualitative research as well as sociology of active living and ageing. She has studied Masters sports for over 20 years and shared her insights from this extensive work in the podcast.
Questions explored in the conversation include: How did the cultural discourses shift in the last 20 years? Have athletes' experiences and meanings of sport also shifted at the same time? What are the different pathways to Masters sport and do they map into different relationships with sport? Why are active ageing discourses also potentially problematic?

"Is walking to school really enough to tackle childhood obesity?" In this third episode, Dr. Olli Tikkanen and Dr. Rob Noonan explore the complex issue of childhood obesity and the social factors that contribute to it. Dr. Noonan shares surprising findings from his research, showing that while children from deprived areas are more likely to walk to school, they are also more likely to struggle with obesity. This challenges the assumption that simply increasing physical activity, like walking, is enough to combat childhood obesity. The discussion delves into the deeper, systemic issues at play, such as poor diets, reduced access to sports, and the social environments in which children live.
The conversation further explores how behavioral interventions alone won’t solve the issue of childhood obesity, as they fail to address the underlying causes - economic, psychological, and environmental factors. Dr. Noonan calls for a broader, policy-driven approach that creates healthier environments for children, rather than just relying on individual behavior change. If you're interested in how policy, environment, and health are interconnected, this episode provides a comprehensive look at the root causes of childhood obesity and what needs to be done to tackle it effectively.

"How do you change a society's values when capitalism rewards consumption and individualism?" In this second part of the episode, Dr. Olli Tikkanen and Dr. Rob Noonan dive deeper into the societal drivers behind health inequality, focusing on the UK and comparing it to other nations like the Scandinavian countries. Dr. Noonan explains how the core values of a society - competition, productivity, and consumption - shape not only individual behavior but also public policy. These systemic values, deeply rooted in the current economic structure, influence everything from public health funding to welfare systems, often leaving health inequalities unaddressed.
The conversation then shifts to the power of education as a tool to reshape these societal values. Dr. Noonan highlights the need for critical thinking and media literacy in the face of overwhelming misinformation, particularly as artificial intelligence and social media complicate the information landscape. He discusses the limitations of the current education system, which often reinforces capitalist values, and suggests that real change will require a bottom-up approach, driven by public support and grassroots efforts. This thought-provoking episode offers a deep examination of the social and political factors that continue to hinder progress in public health and well-being.

/Highlights/ Economic Growth at the Cost of Well-being – Dr. Rob Noonan (Pt1)
Saturday Sep 20, 2025
Saturday Sep 20, 2025
"Our obsession with economic growth might be making us sicker—what can we do about it?" In this powerful first episode, Dr. Olli Tikkanen sits down with Dr. Rob Noonan, an expert in health and education, to explore the critical link between capitalism and public health. Dr. Noonan explains how our relentless focus on economic growth has led to widespread public health issues like obesity, mental health struggles, and increasing health inequalities. As more people consume ultra-processed foods, work longer hours, and face social deprivation, society's overall well-being is declining—and it's time to rethink our approach.
Drawing from his book Capitalism, Health, and Well-being, Dr. Noonan calls for a shift in economic priorities to focus on creating healthier environments, rather than simply growing the economy. He highlights the need to tackle the social determinants of health, showing how where we live, work, and grow plays a crucial role in our health outcomes. This episode sheds light on the systemic drivers of poor health and why individual responsibility isn’t enough to solve these societal issues. If you're interested in the intersection of health, economics, and social justice, this episode is not to be missed.

"What if changing your habits was less about effort and more about strategy?" In this third episode, Dr. Olli Tikkanen continues the conversation with health coach Lotte Arndal, who shares her expertise on behavior change and habit formation. Lotte explains how using advanced tools like Fibion Reports allows her to offer truly personalized advice that goes beyond general fitness tips. She emphasizes that habit change isn't just about extreme effort but about understanding your body’s real needs, and making sustainable adjustments over time.
Lotte also discusses the emotional and psychological aspects of weight management, revealing that many of her clients' eating habits are deeply tied to emotional triggers rather than physical hunger. She shares personal stories of clients who, through her program and the use of Fibion, were able to reshape their lifestyles despite significant health challenges. This episode provides valuable insights for anyone interested in data-driven coaching, emotional health, and long-lasting behavioral change.

"Can you really feel active while barely moving? The numbers tell a different story." In this second episode, Dr. Olli Tikkanen continues the conversation with Lotte Arndal, an experienced health coach and gym owner, as she shares the importance of accurate measurement in health coaching. Using advanced tools like Fibion sensors, Lotte demonstrates how many clients often misjudge their physical activity, confusing mental fatigue with real physical exertion. By analyzing clients’ daily activity data, she customizes advice to fit their true energy expenditure, helping them achieve a healthier, balanced lifestyle.
Lotte also reveals how simple lifestyle tweaks - such as moving more during the day rather than focusing solely on gym time - can make a significant impact. She stresses the need for tailored health strategies, especially for those with low muscle mass or those who have struggled with traditional fitness methods. This episode is essential for anyone looking to understand how real data and simple changes can revolutionize personal health coaching.

Ever feel completely exhausted after a long day but realize you’ve barely moved at all?" In this insightful first episode, Dr. Olli Tikkanen sits down with Lotte Arndal, a seasoned health coach and gym owner with 25 years of experience, to uncover the surprising disconnect between mental and physical exhaustion. Lotte reveals that many people mistake mental fatigue for physical tiredness, leading them to believe they're more active than they actually are. Through her unique, data-driven approach using activity sensors, Lotte helps clients see the reality of their movement patterns - and how simple changes can dramatically improve their health and energy levels.
Lotte also shares her philosophy of keeping health simple and balanced. She discusses how trendy fitness fads, extreme diets, and biohacking often confuse people, pulling them away from sustainable, long-term health habits. Instead, she promotes everyday movement, normal eating, and a common-sense approach to well-being. This episode is a must for anyone looking to break free from complicated health trends and find practical, science-based ways to improve both physical and mental health.
