Most athletes understand that proteins repair and rebuild muscle while carbohydrates provide energy. Some even calculate to the gram the quantities of these macronutrients they consume on training and non-training days. A study published in The Journal of Nutrition illustrates the important role that micronutrients play in physical performance.

Researchers supplemented the daily diets of 7 to 10 year olds with 19 vitamins and minerals. After 120 days, their capacity for exercise was tested through 20-meter shuttle runs, grip strength and forearm hangs. Compared to baseline measurements and a group of subjects that received no micronutrient support, the supplemented students exhibited significantly improved aerobic capacity and endurance.

True Strength Moment: As an active adult, your protein and carbohydrate needs exceed those of less active people. That’s because you’re burning more calories and using a greater amount of nutrients than the average Jane or Joe. This study shows that vitamins and minerals also play a part in helping you stay on top of your game.
