Jeg må da indrømme jeg ikke har læst pubmed igennem for udstræknings-studier. Så det er da muligt der er et par veludførte ind imellem, og det er klart ordet "virkning" bør defineres bedre.
Virkning for mig er umiddelbart sigtet mod DOMS og generel skadesforebyggende, og det er der så vidt jeg ved ikke noget videnskabelig dokumentation for udstrækning hjælper på.
Men ellers held og lykke med dit projekt!
TAK!
DOMS er evidens rimelig entydig at det ikke virker.
I forhold til skadesforebyggelse er der ikke evidens for, at udspænding har effekter i form af nedsat skadesforekomst (McHugh 2010, Herbert 2002 , Matthews 2008). Der er dog generelt brug for flere studier, for at finde ud af, om det kan nedsætte forekomsten af muskel-seneskader (McHugh 2010, Matthews 2008).Det overordnet problem er at mange af de intervention der er lavet med udspænding inkludere andre interventions former også.

The role of stretching in tendon injuries (McNair et al. 2007)
To stretch or not to stretch: the role of stretching in injury prevention and performance (Mchugh 2010)Pope et al. (2000), with 1538 male
military recruits, 7.5% of injuries were muscle strains.
There were 35 muscle strains in the study, 21 of which
occurred in the control group and 14 of which
occurred in the stretching group. The most striking
difference was the occurrence of 10 thigh strains in the
control group vs two thigh strains in the stretching
group. These injuries amount to a 1.2% prevalence in
the control group (10 strains in 803 subjects) vs a
0.3% prevalence in the stretching group (two strains
in 735 subjects), which is statistically significant
(Po0.05). The authors did not perform any analyses
with respect to muscle strains and did not refer to this
apparent difference. While this possible effect of
stretching has a high risk of a type 1 error, the
observation warrants some mention here given the
lack of research on the effect of stretching on muscle
strains. However, considering that the stretching intervention
was probably inadequate to decrease passive
resistance to stretch and that there was not a high
prevalence of muscle strains it is difficult to make any
firm conclusions from these data.
I det studie er der noget der tyder på det, men på den anden side så er mængden af muscle strains i gruppen relativt lille. Jeg har ikke kigget på original studie endnu.
