Higher Vitamin D Levels Linked to Higher Cardiorespiratory Fitness
Cardiorespiratory fitness is the measure of the ability of the heart and lungs to supply oxygen to the muscles during exercise. A recent study suggests that higher blood levels of vitamin D may be associated with higher cardiorespiratory fitness.
Participants in the study included 1,995 people with a mean age of 33. Forty-five percent of the participants were women and 49% were white. Their mean vitamin D levels were 58 nmol/L and their mean VO2 max was 40 ml/kg/min. VO2 is a measure of maximal oxygen consumption during exercise.
After examining the data, the researchers found that the people in the highest quartile for vitamin D levels had significantly higher VO2 max than those in the lowest quartile. They also found that each 10 nmol/L increase in vitamin D was associated with a statistically significant 0.78 mL/kg/min increase in VO2 max.
Researchers from the Virginia Commonwealth University School of Medicine led the study. It was published on October 30, 2018, in the European Journal of Preventive Cardiology.
Vitamin D can be found in milk, fortified cereals, fish, and eggs. Your body also processes vitamin D from the sun, but it becomes harder for our bodies to process it as we age. A high-quality vitamin D supplement is always a good option if you feel that you’re not getting enough through diet and sun.
