Da jeg for nylig skrev et indl\u00e6g om ‘cellul\u00e6r healer’ Daniel Pomba (l\u00e6s her<\/a>)\u00a0kom jeg til at t\u00e6nke p\u00e5 en anden prominent amerikansk personlighed, Dr. Al Sears, der ogs\u00e5 frar\u00e5der udholdenhedstr\u00e6ning for at holde sig i form og leve l\u00e6ngere.<\/p>\n

Al Sears, Amerikas f\u00f8rende anti-aging pion\u00e9r<\/h4>\n

Al sears promoverer sig selv som “America’s #1 Anti-aging pioneer”, og k\u00f8rer bl.a. Sears Instutute for Anti-aging Medicine<\/em>, der tilbyder alternativ behandling med medikamenter, der ikke er p\u00e5 dagsordenen hos den almindelige praktiserende l\u00e6ge. P\u00e5 sin hjemmeside promoverer han ogs\u00e5 en r\u00e6kke kosttilskud under m\u00e6rket Primal Force, der skulle kunne hj\u00e6lpe \u00e9n til sund alderdom. Han har skrevet en r\u00e6kke b\u00f8ger, heriblandt The “Fountain of Youth” Breakthrough<\/em>, 12 Secrets to Virility<\/em>, Reset Your Biological Clock<\/em> og P.A.C.E: The 12-minute fitness revolution<\/em>.<\/p>\n

P.A.C.E. fra 2010, af Al Sears. En tidligere udgave af PACE konceptet blev udgivet i 2006.<\/figcaption><\/figure>\n

HIIT og PACE<\/h4>\n

I bogen P.A.C.E. promoverer Dr. Sears et “revolutionerende” tr\u00e6ningsregime, der dog i bund og grund er en variant af \u00a0h\u00f8j intensitet intervaltr\u00e6ning (HIIT). Denne type tr\u00e6ning var ved f\u00e5 en ren\u00e6ssance omkring tidspunktet, hvor denne bog udkom (i 2010), men har v\u00e6ret benyttet af elite-atleter mange \u00e5r tidligere, og blev i 1990’erne beskrevet som Tabata protokollen (efter japanske Izumi Tabata, der udf\u00f8rte og publicerede en r\u00e6kke studier omkring HIIT). Der er intet odi\u00f8st i at Dr. Sears har fokuseret p\u00e5 HIIT, da der er mange studier, som peger p\u00e5 at metoden er effektiv. Men han g\u00f8r det p\u00e5 bekostning af andre popul\u00e6re tr\u00e6ningsformer.<\/p>\n

I sin bog henviser Dr. Sears til videnskabelig evidens for at aktiviteter som aerobics, jogging og maraton er direkte skadelige for helbredet.<\/p>\n

Aerobics, jogging and marathon running are low-intensity, long-duration exerises. The Harvard study clearly shows that this kind of exercise increases your risk of heart disease and death.<\/p>\n

– Dr. Al Sears, P.A.C.E., 2010<\/p><\/blockquote>\n

Et skud i egen fod<\/h4>\n

Det interessante er, at Dr. Sears\u00a0henviser til to videnskabelige studier udf\u00f8rt p\u00e5 m\u00e6nd (et fra 1995 og et fra 2003), hvor han formentlig ikke selv har l\u00e6st artiklerne. I alt fald misbruger han konklusionerne. I studiet fra 1995 konkluderer forfatterne, at m\u00e6nd (gennemsnitsalder, 46 \u00e5r p\u00e5 starttidspunktet, i en unders\u00f8gelsesperiode, der strakte sig over mere end 20 \u00e5r) havde h\u00f8jere overlevelse, hvis de tr\u00e6nede relativt h\u00e5rdt i forhold til, hvis de tr\u00e6nede let til moderat. Personerne i den let til moderate gruppe havde dog ikke d\u00e5rligere overlevelse end de som blev defineret som den inaktive kontrolgruppe. Det skal noteres, at relativt h\u00e5rd tr\u00e6ning blev defineret som l\u00f8b, jogging, hurtig gang, tennis og manuel snerydning – intet der kunne defineres som HIIT eller PACE. En tilsvarende konklusion blev draget p\u00e5 baggrund af studiet fra 2003, hvor der blev kigget p\u00e5 udvikling af hjertesygdom for\u00a0en gruppe m\u00e6nd med en gennemsnitsalder p\u00e5 66, der blev opdelt i flere niveauer efter indrapportering af fysisk aktivitet. Rapporteringen benyttede den \u00a0s\u00e5kaldte Borg-scala, og deres cut-off for den \u00f8verste gruppe var niveau 5 (p\u00e5 en skala fra 1 til 10), svarende til, at man kan f\u00f8re en samtale under tr\u00e6ning – igen langt fra HIIT niveau.<\/p>\n

These data demonstrate a graded inverse relationship between total physical activity and mortality. Furthermore, vigorous activities but not nonvigorous activities were associated with longevity. These findings pertain only to allcause mortality; nonvigorous exercise has been shown to benefit other aspects of health.<\/p>\n

– I-Min Lee et al, The Harvard Alumni Health Study, 1995<\/p><\/blockquote>\n

S\u00e5 Al Sears’ konklusioner omkring udholdenhedstr\u00e6nings skadelige effekter er rent faktisk baseret p\u00e5 data, der helt modsat peger p\u00e5, at udholdenhedstr\u00e6ning rent faktisk er sundhedsfremmende.<\/p>\n

Det er i \u00f8vrigt ikke det eneste sted i P.A.C.E., hvor\u00a0Dr. Sears tolker lidt l\u00f8st p\u00e5 resultaterne fra videnskabelige studier. Man kunne derfor overveje om de Anti-aging produkter han promoverer bliver anprist efter samme tvivlsomme principper.<\/p>\n
