Highlights-ABCs: How to Measure Physical Activity with Devices? (Pt2) Drs Cabrita and Tikkanen

5 days ago

What are the basics of physical activity measurement with devices?
a. Sensor location: thigh, hip, back, wristb. Type of data you can get: raw -> steps -> activity type -> activity intensity -> “complexity”c. Considerations to have when choosing a sensor i. User-friendliness (battery, aesthetics, comfort, interaction required)d. Feedback to participants i. Real-time or at defined momentse. Feedback to practitioners (dashboard)f. In most cases, you can also measure sleep.

/Highlights/ Alternative Activities for Physically Inactive Children - Dr Johan Högman (Pt2)

Sunday Apr 05, 2026

Promoting Playful Activities in Sports: "They have to be more playful elements and basically activities that have other logics than winning and competing and comparing."— Dr Johan Högman---Timestamps:
"Exploring Views on Getting Children Involved in Sports"
"Challenging initiatives fail to attract inactive children"
"Revamping Children's Sports: Beyond Winning and Competing"
"Alternative Physical Activities vs Traditional Sports Programs"
"Alternative physical activity for inactive children tested"
Johan Högman is interested in the social and cultural dimensions of how and why children move their bodies. He believes that physical activity is important for all children, regardless of the type of activity, and that understanding the societal views of physical activity is vital in ensuring that more children are able to participate. Johan's research involves digging deeper into the conditions that impact physical activity in children and the factors behind why some children may not be as active as others. Overall, he is passionate about promoting physical activity and helping more children to move their bodies in healthy ways.----"On this episode of Physical Activity Researcher Podcast, we discuss the challenges of engaging physically inactive children in sports activities. Our speaker explains that while some children love sports and physical activity, those who are not as active perceive it as sporty and competitive, making them less likely to participate. To address this issue, our researcher recommends changing the ordinary business of sports clubs and offering more diverse activities that appeal to non-athletic children. The episode covers the use of the bioecological theory to understand the factors that prevent children from enjoying physical activity. The theory helps to examine individual traits and abilities and how they interact with the cultural and environmental factors. The podcast also shares insights on the best practices for conducting focus groups to collect children's experience and perceptions regarding physical activity. Finally, our speaker talks about the ongoing efforts to come up with alternative physical activities that are enjoyable and accessible to inactive children by conducting a 12-week program with playful activities like Pokemon Go and trampoline parks to measure the effectiveness compared to traditional sports activities."----

/Highlights/ Inside the Bubble: Examining the Impact of Organizational Culture on Youth Athletes’ Career Development - Dr Aku Nikander (Pt 2) - Meaningful Sport Series

Saturday Mar 28, 2026

In today's episode, we continue our conversation with Dr. Aku Nikander, delving into the challenges faced by young athletes in their career journeys. Aku shares his findings on the role of sport organizations in shaping the aspirations and possibilities of youth athletes. Specifically, we uncover the impact of organizational culture and the tensions that arise when implementing a dual career approach in a talent development environment.
The conversation focuses on Aku's case study in a talent development environment that has been in existence for decades. Informed by the European Commission's dual career guidelines and the broader movement around dual careers, the organization defines itself as a dual career development environment. Curious about the integration of this concept at different cultural levels within the organization, Aku examines how well it supports dual career development as outlined in existing research and literature. Specifically, Aku focuses on the cultural aspects, as they greatly influence the thinking, development, behavior, and well-being of group members. With a particular interest in the coaches' adoption of dual career thinking and the athletes' career goals, Aku conducted observations and interviews in the environment to gain a comprehensive understanding of the dynamics at play.

/Highlights/ How to Provide Feedback to Children Related to Their Sedentary Behaviour and Physical Activity? Dr Amy Creaser (Pt2)

Sunday Mar 08, 2026

Amy has an undergraduate degree in Psychology from the University of Leeds, who undertook a work placement year at BiB in 2017, working on the ‘Primary School Years’.Amy is currently a PhD Student, working with the JU:MP team and Loughborough University. Her PhD will focus on developing and implementing an intervention to increase physical activity in children and adolescents, using wearable activity trackers (such as Fitbits). Her PhD will take a mixed-methods approach (qualitative and quantitative methods) to investigate intervention impact and assess feasibility and acceptability of the intervention within the community.
