New @WHO guidelines now include recommendations to limit #sedentary behaviour and replace with #physical activity of any intensity, but still a lot of room to improve and expand the evidence-base #EveryMoveCounts
Every move counts! Evidence for new @WHO #sedentary behaviour guidelines ➡️Substantial health gains from limiting sedentary time ➡️Replace sedentary behaviours with #physicalactivity of any intensity 👉🏽ijbnpa.biomedcentral.com/articles/10.11… By @PC_Dempsey @fiona_bull et al @IJBNPA

We are quick to set screen time limits on kids, but what about parents? See our piece out today in The Conversation: theconversation.com/were-quick-to-… @ConversationEDU @PC_Dempsey @Lauren_Arundell @DavidWDunstan Mats Hallgren @Fronj @DeakinIPAN #ScreenTime #parenting #sitting
📢Excited to share a comprehensive scoping review led by @hmlyoungphysio on PA/sedentary behaviour interventions for #MLTCs & #frailty Some key gaps: ❌ Limited focus on sedentary behaviour ❌ Minimal (reported) carer involvement ❌ Homogeneity in populations More work needed! 👉
Finally published! Physical activity & sedentary behaviour interventions for ppl living w/ both #frailty & #mltcs & their carers: a scoping review academic.oup.com/ageing/article…

Honoured to be shortlisted for an @aipolsci 2024 #YoungTallPoppy Award! Grateful for the chance to contribute to clinical and public health research, and to be part of a campaign that promotes scientific literacy and excellence while inspiring new generations of scientists #STEM
Thrilled to announce Dr @PC_Dempsey is a 2024 @aipolsci #YoungTallPoppy finalist! Paddy’s research sheds light on how different amounts, intensities and patterns of physical activity and sedentary behaviour can improve cardiometabolic health. @deakinresearch | @BakerResearchAu
How much exercise is needed to increase life expectancy? Turns out a little goes a long way. This new study in over 71,000 people (aged 60+) found: ➡️Higher volumes and intensities of exercise = greater benefits (up to 3.5 to 4.6 extra years for women and men, respectively).…
Nice harmonized accelerometer meta-analysis led by @JakobTarp across 9 prospective studies in adults—building up activity volume linked to lower mortality risk, with some added benefit from more moderate intensity activity ajpmonline.org/article/S0749-… #PublicHealth #PhysicalActivity
@PC_Dempsey expertly concluded the Highlighted Symposium on "The Physiology of Sedentary Behavior," offering insightful perspectives on translating experimental data into practical guidelines and highlighting key knowledge gaps and future research directions. #ACSM24
Nicely set up Symposium by @MarsApovian @jmjakicic @ReneeJRogers on focusing/positioning PA & lifestyle modification in the context of contemporary anti-obesity drugs (eg GLP-1 RAs). Rapidly moving space. New ACSM consensus statement on obesity management coming soon! #ACSM24
Mark Hargreaves presents the DB Dill Historical Lecture - "Exercise Physiology in a Molecular Age". A legend in the science of exercise & muscle biology, but I'll always remember him more for being a top bloke and mentor/role-model. All the best with 'retirement' 🙂 #ACSM24
Steps for health: where are we up to? Nice evidence synthesis and discussion by @BorjadelPozoCr1 on the opportunities, but also challenges, of such metrics. How many steps optimal? Do all steps count? Will we see steps-based recommendations in future guidelines?... #ACSM24
Informative talk by Stuart Trost about the uptake and implementation of machine learning techniques with wearable devices: is there a lack of innovation or diffusion failure? Announces new 'Actimetric' R package in R #ACSM24
Informative overview and introduction by @Matthew_Ahmadi_ to the Highlighted Symposium - "Novel Insights on Physical Behaviour and Non-Communicable Disease through Application of Wearables". #ACSM24. Large potential of wearable sensors and AI to inform the evidence-base.
Nicely tied together talk by @karmelchoi on the genomic perspectives of physical activity and depression relationships, contributing to further triangulation of evidence to inform potentially more precise physical activity interventions. #ACSM24
Great summary by @JMeyer37 on Expanding evidence for the use of exercise in the treatment of depression. No clear optimal prescription. Can we capitalise on the acute effects (psych priming window) of exercise for depression? #ACSM24
@DavidWDunstan, @AnaJPinto, Ed Doyle, @PC_Dempsey, and I are excited to have presented at the Highlighted Symposium on "The Physiology of Sedentary Behavior" at #ACSM24 today in Boston. Most data were recently discussed in an exhaustive review (Pinto AJ et al. 2023 Phys Rev).
Sit less: @A_Bergouignan tells us in detail about the physiopathology of sedentary behavior & underlying biological mechanisms. Lots of health effects across various experimental models. Strategies needed to reduce! #ACSM24
Exercising is not enough: The influence of sedentary behavior on the relationship between exercise and health outcomes. Ed Coyle gives an interesting talk on the recent evidence on "exercise resistance". Is it a 'harbinger' or a 'culprit'? #ACSM24
