Halvard Grendstad, PhD

@phd_sean @ValerengaOslo Thank you Sean!

Great to see @GrendstadH lead on physical development for the boys and girls football academies at @ValerengaOslo. Great article detailing his strategy to accommodate for G and M in athlete development 👏🇳🇴⚽️tinyurl.com/335w56hu

Great trip to Norway with @David_johnson11 to help @eirikwik @GrendstadH @ThomasBroBra and the @nff_info educate academy staff on growth and maturation in academy football @UniofBath @CHi2PSBath @UKCCIIS #heianorge 👏⚽️🇳🇴🔬

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🩸

Really nice set of images illustrating the variance in maturation that can exist within age groups

@dcturner93 @LosnegardThomas @amelie_w58 Congrats mate, great achivement!!

What a great experience competing in birken with @GrendstadH!. A well-organised event with fascinating history! Also, special thanks to my good friend Magne Lund-Hansen and @LosnegardThomas for their fantastic coaching and to @amelie_w58 for her patience during our ski trips⛷️

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 @GrendstadH #langrenn forskning.no/barn-og-ungdom…

New publication out: "Exploring growth, maturity and age as injury risk factors in high-level youth football"⚽ Preliminary (pre-typeset) full-text available here: tinyurl.com/3a6jabe9

🆕 First PhD study out! 🏃Coaching youth athletes and considering to boost fitness in pre-season? 👇 🔍Our findings show that high-intensity training do not improve VO2max more than low-intensity strength or play-based training. Link: doi.org/10.1111/sms.14… @JosteinHallen

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!

🎧 En flott podcast av @jevnehelse og @StianChri1 som jeg fikk være gjest på sammen med @eirikwik 🏃🏼‍♂️🩻 🌱 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…

🌱Puberty is an important time for healthy and strong bones to develop 🦴 🏃🍽️For young athletes, eating enough food and vit D are two factors to promote healthy bones and possibly reduce injury risk, especially during the dark winter (hey all🇳🇴🇸🇪) A nice short review on this👇

"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 @H_Herrebroden og meg #idrett #talentutvikling dagsavisen.no/debatt/2023/06…

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…

Hvis du vil vite mer om pubertet og prestasjon har jeg snakket i en podcast med DBU 🇩🇰 om tema tidligere 👇 gamechanger.nu/podcast/praest…

Flott at NFF er på ball, med en strategi Belgia startet for mange år siden 👍 Ett godt tiltak, men vi har fortsatt mye å hente på å utjevne forskjeller i ungdomsfotball. vg.no/i/Kn17j7?utm_s…

Signs of athlete's heart already by the age of 12 in👧&👦endurance athletes. Through adolescence, boys🫀 adapt and enlarge more than girls🫀. Nice figs and study with data from a cohort in our research group @MarianneForsaa @JosteinHallen @ThorEdvardsen openheart.bmj.com/content/10/1/e…

💥 Great review discussing the challenge of maturation in youth (male) sport, and the different approaches to level the playing field in selection and training/competition 👇🏼 mdpi.com/2058514 #mdpichildren via @MDPIOpenAccess

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…

@dcturner93 8am way to early for me to start singing Justin Bieber 😂

@GrendstadH Question is, did you join in? 😉

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 🤷🏼‍♂️😅
