Research does not always involve lab coats and measuring o2 and blood 🌡 Various efforts are done behind the scenes but are rarely revealed. Mine today: Picking up our 13-yr old subjects in a bus 1hr from of our lab, listening to them singing Justin Biebers “Baby” on repeat 🤷🏼‍♂️😅

Offside rule 101 with some very nice graphics. Nothing new here (for those who knows the rules) but maybe some inspiration to explain other complicated topics in an easy way 🤩 washingtonpost.com/sports/interac…

Godt skrevet om utfordring i idretten Mer fokus på tidlige resultater og prestasjon er ikke en god utvikling, og heller ikke noe det er bevis for at gir bedre prestasjoner som voksen. Barneidrett må være for barn, ikke voksne Tid for selvransakelse nrk.no/ytring/1.16431…

"Den tidlige veien til voksenidrett er ikke for alle" 🧊 Vi trenger litt is i magen og ekstra tålmodighet når vi skal utvikle våre neste idrettsutøvere. Alle blir voksen til slutt 🌟💪 En kommentar fra Henrik Herrebroden og meg #idrett #talentutvikling dagsavisen.no/debatt/2023/06…

🎧 En flott podcast av Jørgen Jevne og Stian Christophersen som jeg fikk være gjest på sammen med Eirik Halvorsen Wik 🏃🏼‍♂️🩻 🌱 Topp diskusjoner rundt vekst, skader og effekt av trening i puberteten. Kan være mye å plukke opp for trenere og andre med fot i ungdomsidretten 🙋🏼‍♂️ podcasts.apple.com/no/podcast/von…

This is definitely worth a read for those interested in maturity-biases in sports - lots of great insights and quotes from coaches on advantages/disadvantages of maturing early or late in academy football!

Spennande forskingsnytt nå like før skisesongen startar. 12-åringar som trena hardt blei ikkje betre enn dei som hadde leika. – Funna våre viser at puberteten er den viktigaste faktoren for utvikling av kondisjon, seier stipendiat Halvard Grendstad, PhD #langrenn forskning.no/barn-og-ungdom…

Presenting some very interesting findings at #acsm2024 on endurance-training girls that hopefully will be published in a journal soon 👇 The impact of puberty strongly influences the development of VO2max and may obscure potential training-induced changes for the 🫀 and🩸
