Neither the subjects nor the investigators knew which participant received the vitamins or placebos. <\/p>\n The participants completed an endurance training programme, consisting of three to four sessions per week, of primarily running. Fitness tests, blood samples and muscle biopsies were taken before and after the intervention. <\/p>\n Whilst the supplements did not affect maximal oxygen uptake or the results of a 20 metre shuttle test, the results showed that markers for the production of new muscle mitochondria the power supply for cells increased only in the group without supplements. <\/p>\n <\/p>\n See the article here: PUBLIC RELEASE DATE: 2-Feb-2014 Contact: Lucy Holmes LHolmes@physoc.org<\/a> 44-020-726-95727 Wiley Vitamin C and E supplements may blunt the improvement of muscular endurance by disrupting cellular adaptions in exercised muscles suggests a new study published today [3 February] in The Journal of Physiology.
