Pwopriyete friksyon-redwi nan manbràn yo yo lajman detèmine pa tanperati deyò a, selon etid Izraelyen an. Anviwon 1.400 sòlda yo te antrene nan diferan moman nan ane a menm kondisyon yo. Nan sezon fredi, risk pou aksidan an te pi wo pase an ete. Syantis yo asime ke frèt fè kouch nan mukopolysaccharide nan tandon an Achilles, ki se tou pre po a, plis gluan. Sa a ogmante friksyon an ak risk pou yo blese.

The friction-reducing properties of the membranes are largely determined by the outside temperature, according to the Israeli study. About 1, 400 soldiers were trained at different times of the year under the same conditions. In winter, the risk of injury was higher than in summer. The scientists assume that cold makes the mucopolysaccharide layer of the Achilles tendon, which is close to the skin, more viscous. This increases the friction and the risk of injury.
