New Study Finds Vitamin D Will Help Boost Your Fitness Levels
Feel like your fitness levels could do with a boost? Well, you might want to pump some more Vitamin D into your diet.
That’s according to a new study published today in the European Journal of Preventative Cardiology. Researchers analysed data from nearly 2,000 people aged between 20 and 49 who voluntarily participated in a national health survey from 2001 to 2004.
Participants had blood samples taken to analyse the levels of vitamin D in their blood. They then underwent an exercise test to measure their VO2 max – which is basically just a more scientific way of referring to your cardiorespiratory fitness. The higher it is, the greater your fitness level.
After running it out on the treadmill, the participants were split into five groups based on their vitamin D levels. As it turns out, the group with the highest vitamin D levels also had the highest VO2 max levels.
The study also found that your VO2 max levels could also be increased if your vitamin D levels were increased.
Doctor Amr Marawan, assistant professor of internal medicine at Virginia Commonwealth University, said the research proves "that higher levels of vitamin D are associated with better exercise capacity".
While scientists are still unsure why vitamin D helps with our fitness levels, there may be a biological explanation behind the findings. According to Dr Marawan: "We also know from previous research that vitamin D has positive effects on the heart and bones".

The way it does that is by binding to the vitamin D receptors which are already found in many of our cells -- including heart muscles.
As for how we can get more vitamin D into our lives, Dr Marawan has this advice: “Make sure your vitamin D levels are normal to high. You can do this with diet, supplements, and a sensible amount of sun exposure."
