Physical Fitness In Adolescents Associated With Sufficient Levels Of Iron, Vitamin C

August 8, 2012: 12:00 AM EST
Researchers in Spain have found that the blood levels of various micronutrients such as iron and vitamin C in adolescents correlate with performance on physical fitness tests. Researchers analyzed nutrition and fitness data from a larger, long-term research project involving thousands of adolescents across Europe. The researchers found that for cardiorespiratory fitness, concentrations of hemoglobin, retinol, and vitamin C in males and beta-carotene and vitamin D in females was associated with maximum fitness. Concentrations of hemoglobin, beta-carotene, retinol, and alpha-tocopherol in males and beta-carotene and vitamin D in females were associated with better performance in the standing long jump.
