Why & When?

Occlusion training for bodybuilders only?

No, not at all! In fact, there are important research on miscellaneous muscle and skeletal pathologies which proves that occlusion training has significant effect on both strength and Patient Reported Outcome Measures (PROM)!

As a rule of thump occlusion training is indicated if you have an acute or overload injury where you cannot do conventional resistance training i.e. lift heavy. For example, following orthopedic surgeries with relevant weight-bearing restrictions. Or more chronic conditions such as arthritis, as a majority will find joint pain worsens during heavy training. In theses cases occlusion training should be “first-line therapy”.

One can wonder why few private or public providers offers BFRE? – But as with so much other new technology, thus evidence-based by research, the implementation is always delayed. Especially considered the amount of high quality research i.e. randomized controlled trials and the meta-analysis, occlusion training is here to stay and grow in popularity.

Below is listed some of the relevant issues and pathologies in which scientific litterature suggests that occlusion training is an effective treatment strategy

Hvorfor & Hvornår?

Okklusionstræning kun for bodybuildere?

Nej, ikke udelukkende! Faktisk er der forskning inden for flere forskellige muskel-og skeletproblemstillinger som viser, at okklusionstræning har signifikant effekt!

Generelt så er okklusionstræning indiceret, hvis man har en akut- eller overbelastningsskade, hvor man ikke kan eller må træne tungt. Fx efter operationer, hvor man enten ikke må løfte tungt eller der er vægtbæringsrestriktioner.

Ved andre kroniske tilstande som fx flere gigttyper, vil en majoritet opleve at ledsmerterne forværres med tung træning, netop her bør okklusionstræning være “first-line therapy”.

Man kan undre sig over, at få private og offentlige udbydere kan tilbyde okklusionstræning? – Men det er ligesom med så meget andet medicinsk teknologi inden for det etablerede sundhedsvæsen, at selvom evidens er uomtvistelig, så er implementeringen altid forsinket. Med udgangspunkt i de randomiserede kontrollerede forsøg (lodtrækningsforsøg) og deraf metaanalyserne, så burde okklusionstræning allerede være et tilbud til flere patientgrupper.

Nedenfor er der en oversigt over de primære problemstillinger, hvor man videnskabeligt har fundet evidens for at okklusionstræning er et effektfuldt alternativ til anden træning.

    • Uspecifik knæ- og hoftesmerte (1,2,3)
    • Gigt herunder osteoartrose og reumatoid artrit (slidgigt og leddegigt) (4,5,6)
    • Genoptræning efter korsbåndsskader før, efter eller uden operation (7,8)
    • Patella femorale smerter (PFP – forreste knæsmerter) (9,10)
    • Alloplastikker (kunstig skulder, hofte og knæ) (11)
    • Degenerative og akutte meniskskader (12,13)
    • Hofte impingement (FAI – afklemningssymptomer) (14)
    • Uspecifik skuldersmerte (15,16)
    • Osteoartrose i skulder- og kravebensleddet (15,16)
    • Frossen skulder (15,16)
    • Knoglebrud (17,18)
    • Seneskader og seneoperationer (14,19,20)
    • Diskusprolaps og uspecifikke rygsmerter (21,22)
    • Bruskskader (23,16)
    • Forskellige muskelskader fx fibersprængninger (1)
    • Osteopeni og osteoporose (afkalkningstilstande) (23)
    • Generel muskelopbygning for alle som et alternativ eller supplement til anden træning (25)
    • Specifik sportsstøttetræning (26,27)
    • Konditionstræning – lavbelastningstræning på motionscykel, løbebånd eller crosstrainer (28,29,30)
