Vitamins C and E prevent the development of muscular endurance – Mednovosti.

A study by Norwegian scientists showed that vitamins E and C violate the cellular adaptation to exercising the muscles that prevents the development of muscular endurance athletes.

“the Results showed that vitamins C and E prevent the increase of mitochondrial proteins, which are needed to improve muscular endurance”, – prozitirovat Science Daily the words of a leading

researcher Goran Paulsen (Goran Paulsen) from the Norwegian Institute of sport.

In an 11-week double-blind randomized study involved 54 young and healthy men and women. One group of subjects received 1000 mg vitamin C and 235 mg of vitamin E, the other a placebo. The trial participants trained three to four times a week, aimed at improving muscular endurance program, mostly involving running. Before and after the experiment, the subjects performed tests of endurance, took blood tests and muscle biopsy.

The results of the study showed that in muscle cells, the number of mitochondria responsible for energy production has increased only in the group where vitamin supplements are taken.

«High doses of vitamins C and E, which are contained in food supplements should be used with caution, especially if you exercise”, said Profesor Paulsen.

Now scientists plan to continue research and to identify molecular mechanisms underlying the results. According to the authors, most likely, vitamins interfere with cell signaling and expresion of specific genes.
