"Kaffe bra för muskelbyggare"

Muskelbyggare vetifasiken var de fick ifrån. Hur som intressant artikel, 66% låter som att det är ganska mycket. Är det någon som vet mer om detta?

[KaptenKnäsvag]

Jag förstår inte hur SvD kan ha en sådan dum titel. Det är väl inte korrekt svenska, eller misstar jag mig?

Variationer bör vara;

"Kaffe är bra..."
"Kaffe, bra för..."
"Kaffe - bra för..."

De kan lika gärna döpa om tidningen till Svänska Dagbladdet.

Ang. topicen; Kaffe är bra. Hörde i någon föreläsning att koffeinet kan öka styrkan upp till 20% hos vissa människor - om de tar en kopp innan gymmet. Däremot har jag inte hört talas om att det skall hjälpa återhämtningen, sannerligen en intressant studie =).

We determined the effects of the co-ingestion of caffeine with carbohydrate on rates of muscle glycogen resynthesis during recovery from exhaustive exercise in 7 trained subjects who completed 2 experimental trials in a randomized, double-blind crossover design. Prior to an experiment subjects performed exhaustive cycling and consumed a low-carbohydrate diet. The following morning subjects reported to the lab and rode until volitional fatigue. Upon completion of this ride subjects consumed either carbohydrate (CHO; 4 g.kg BM-1) or carbohydrate plus caffeine (CAFF, 8 mg.kg BM-1) during 4 h of passive recovery. Muscle and blood samples were taken throughout recovery. Muscle glycogen levels were similar at exhaustion and increased by a similar amount after 1 h of recovery. After 4 h of recovery CAFF resulted in higher glycogen accumulation (313 ± 69 vs. 234 ± 50 mmol±kg- d.w, P<0.001). The overall rate of resynthesis for the 4 h recovery period was 66% higher in CAFF compared to CHO (57.7 ± 18.5 vs. 38.0 ± 7.7 mmol±kg-1 d.w.h-1, P < 0.05). Phosphorylation of CAMKThr286 was similar post-exercise and after 1 h of recovery but after 4 h CAMKThr286 phosphorylation was higher in CAFF than CHO (P<0.05). Phosphorylation of AMPKThr172 and AktSer473 was similar for both treatments at all time points. We provide the first evidence that in trained subjects, the coingestion of large amounts of caffeine with carbohydrate has an additive effect on rates on post-exercise muscle glycogen accumulation compared to when carbohydrate alone is consumed.

Är väl denna studien det gäller

Svårt att säga någonting utifrån abstraktet men det verkar som om de som intog koffein ihop med kolhydrater hade högre nivåer av signalmolekyler som reglerar glykogeninlagringen.

Edit: För långsam

Wtf, såg nu att jag har startat en tråd om den där studien för ett tag sen:

8 mg/kg är inte direkt lite koffein. Synd att det var så mycket, blir inte direkt sugen på att testa och utvärdera. Kanske fungerar rätt bra med lite mindre mängd också iof.

Ah, lås den här då :)

Okej. Diskutera gärna vidare i den dock.:)
