[Vitamin P in the nutrition of athletes]

Capillary resistance was examined in 1203 athletes, students of the Institute of Physical Culture. The examinees showed seasonal variations in capillary strength and in excretion of ascorbic acid with the urine. It is recommended that the diet of athletes be supplemented with vitamins C and P during winter season. Both vitamins were demonstrated to interfere with the effect of sports exercise affecting capillary walls. The vitamins can be used for raising the efficacy of ski training and improving the results during competition. It is also advisable that the diet be supplemented with vitamin P daily dose of 50-60 mg given with rutin, which is best combined with 100 mg of ascorbic acid.
