Ka\u017ed\u00fd ponor, i ten jednoduch\u00fd v r\u00e1mci bezdekompresn\u00edch limit\u016f, vede ke vzniku bublin: s poklesem tlaku se inertn\u00ed plyn uvol\u0148uje z roztoku a vytv\u00e1\u0159\u00ed \u017eiln\u00ed plynov\u00e9 emboly, kter\u00e9 t\u011blo za b\u011b\u017en\u00fdch okolnost\u00ed odfiltruje, ani\u017e by se projevily jak\u00e9koli p\u0159\u00edznaky.

Ji\u017e v roce 2015 si belgick\u00fd t\u00fdm pod veden\u00edm Sigrid Theunissenov\u00e9 a Costantina Balestry (viceprezidenta pro v\u00fdzkum v organizaci DAN Europe) polo\u017eil z\u00e1sadn\u00ed ot\u00e1zku: mohou antioxidanty obsa\u017een\u00e9 v ho\u0159k\u00e9 \u010dokol\u00e1d\u011b zm\u00edrnit endoteli\u00e1ln\u00ed stres po pot\u00e1p\u011bn\u00ed?

Ve studii bylo 42 mu\u017esk\u00fdch pot\u00e1p\u011b\u010d\u016f rozd\u011bleno do dvou skupin: jedna se pot\u00e1p\u011bla bez z\u00e1sahu, druh\u00e1 sn\u011bdla 30 gram\u016f ho\u0159k\u00e9 \u010dokol\u00e1dy asi 90 minut p\u0159ed ponorem.
