non vedo evidenze, sono sicuro che ci siano dall'ardore delle vostre motivazioni e non metto in dubbio il punto, fatto sta che continuo a leggere che esistono prove scientifiche ma non ne ho evidenza
ercole le evidenze sono studi scientifici, riproducibili e confutabili da chiunque pubblicati su riviste scientifiche.
Se vuoi gli articoli completi, ti ripeto, devi pagare 59 dollari ad articolo altrimenti devi farti bastare gli abstract disponibili per tutti.
continuare a dire non vedo evidenze è sciocco dal momento che non le hai cercate.
facciamo così ti dò qualche aiuto io sulle evidenze:

Is stretching for sports performance still useful? A review of the literature
Hôpital orthopédique de la Suisse romande,
Swiss Medical Olympic Center
estratto:Since 1980, according to several authors, it is accepted that increasing flexibility of a muscle-tendon unit allows a better performance and decreases sports injuries. Stretching is regularly included in warm-up and in cooling-down. However, there are contradictory findings in the literature. In contrast, since 1990, there's evidence suggesting that stretching not only does not prevent injuries, but can also decrease the level of performance. Some part of these contradictions can be explained by the various sports activities. Those requesting an increased flexibility, such as gymnastic, dancing or diving, necessitate stretching to optimize the level of performance. In contrary,
for sports with slow stretch-shortening cycle such as jogging or cycling, there is no scientific data showing a positive effect of stretching.

The impact of stretching on sports injury risk: a systematic review of the literature.
(visto che prima dicevate che uno studio deve essere fatto in un determinato modo vi scrivo come hanno fatto questa revisione, solo per esempio)
METHODS: Without language limitations, we searched electronic data bases, including MEDLINE (1966-2002), Current Contents (1997-2002), Biomedical Collection (1993-1999), the Cochrane Library, and SPORTDiscus, and then identified citations from papers retrieved and contacted experts in the field. Meta-analysis was limited to randomized trials or cohort studies for interventions that included stretching. Studies were excluded that lacked controls, in which stretching could not be assessed independently, or where studies did not include subjects in sporting or fitness activities. All articles were screened initially by one author. Six of 361 identified articles compared stretching with other methods to prevent injury. Data were abstracted by one author and then reviewed independently by three others. Data quality was assessed independently by three authors using a previously standardized instrument, and reviewers met to reconcile substantive differences in interpretation. We calculated weighted pooled odds ratios based on an intention-to-treat analysis as well as subgroup analyses by quality score and study design.
RESULTS: Stretching was not significantly associated with a reduction in total injuries (OR = 0.93, CI 0.78-1.11) and similar findings were seen in the subgroup analyses.

To stretch or not to stretch: the role of stretching in injury prevention and performance.
A general consensus is that stretching in addition to warm-up does not affect the incidence of overuse injuries.
