Sidst opdateret: 21. december 2021 4 minutters læsetid  En hurtig indføring i, hvorfor foamrolling føles så godt: "Trykket fra din kropsvægt på cylinderen får spændinger til at løsnes i fascieområdet – det sammenhængende net af væv, der løber gennem kroppen – for at forbedre din fleksibilitet og bevægelighed i den underliggende muskel", siger John Porcari, ph.d. og Program Director of Clinical Exercise Physiology på University of Wisconsin–La Crosse. Det er svært at måle restitutionsredskabets effektivitet. Der er ikke mange videnskabelige beviser, der peger i retning af, præcis hvordan en skumrulle skal bruges for at få de bedste resultater (forskellig størrelse og hårdhed er én af de ting, der gør det svært at indsamle evidens). Men et nyligt studie, som Porcari ledte, fandt, at der helt sikkert er *nogle* fordele. Dette gælder særligt, hvis du lider af spændinger i lænden eller har stramme haser – de muskler, der løber på bagsiden af dine lår fra dine hofter til dine knæ. Begge dele kan skyldes, at du sidder meget ned eller træner for hårdt. (Du passer nok ind i mindst én af de to kategorier?) I løbet af undersøgelsen, der forløb over seks uger, brugte 20 mandlige og kvindelige frivillige en rillet skumrulle på 14 x 33 cm i 15 minutter tre gange om ugen. De rullede på lænd, balder, lår, hoftesene, haser og lægge 20 sekunder hver og gentog det tre gange i samlet 60 sekunders rulning på hver kropsdel. Efter de seks uger kunne de frivillige strække sig fem cm længere i en sid-og-nå-test (jep, ligesom den, du lavede i træningscentret), end de kunne, før de brugte en skumrulle. "Vi fandt en betydelig forbedring af fleksibiliteten i lænden og haserne," fortæller Porcari. Dine haser strækker dine hofter og bøjer dine knæ, mens de er med til at stabilisere din core og dit bækken. Når dine haser er stramme, trækker de sig sammen og bliver kortere, hvilket skaber en kædereaktion af ubehag eller smerte. "Stramme haser trækker dit bækken ned bagpå, hvilket lægger ekstra belastning på muskulaturen i lænden og giver smerter,” forklarer Porcari. Vil du gerne løbe, lave squats eller løfte en indkøbspose med den slags spændinger? Nej, det regnede jeg heller ikke med. ## "Vi fandt en betydelig forbedring af fleksibiliteten i lænden og haserne". __John Porcari__, Ph.d., Program Director of Clinical Exercise Physiology ved University of Wisconsin–La Crosse Forskerne så også på, om brug af en skumrulle kunne have en negativ effekt på atleters præstationer, hvor man målte vertikalt hop og fandt ud af, at det ikke var tilfældet. Hvad vigtigere var, så opdagede de, at de frivillige, der brugte skumrulle, følte sig mere fleksible, og at de kunne hoppe højere ved slutningen af undersøgelsen. "Det vigtigste resultat er, at folk kan lide at bruge en skumrulle og nød det," siger Porcari. "Uanset om der kunne måles fordele eller ej, så syntes personerne, at det gjorde noget godt for dem". Det betyder, at placeboeffekten ved skumrulning er virkelig. Og når man tænker over, at videnskaben ikke viser, at skumrulning har nogen negative effekter på din træning og restitution, så gælder det, at "jo mere du gør det, desto bedre," siger Porcari. ## Løsn op på bare tre minutter Du skal bruge en stor skumrulle. En med riller er ideel, men du kan også bruge en glat, hvis du ikke har andet. ## Rulning af lænden Sid på gulvet med bøjede ben og skumrullen bag dig vinkelret mod din krop. Løft din venstre hofte for at placere højre side af din midterste del af ryggen på rullen, og drej din torso lidt mod højre, mens du holder din højre underarm i gulvet. Stræk dine ben for at rulle fra midterste del af ryggen til din bagdel, bøj derefter dine knæ for at rulle tilbage. Fortsæt langsomt i 20 sekunder. Gentag på modsatte side. ## Rulning af hasen Sid på gulvet med dine ben strakt og skumrullen under din venstre hase. Placer dine hænder fladt på gulvet bag dig, skub så med håndfladerne for at støtte din vægt, mens du ruller op og ned mellem øverste del af bagsiden af dine knæ og nederste del af dine balder i 20 sekunder. Gentag med den anden side. Lav hver af disse øvelser tre gange i i alt tre minutter. Forsøg at gøre dette tre eller flere dage om ugen, før du træner.
