Optimal energy intake for performance health

As the performance health series continues, let’s stop to catch our breath, and briefly review where we’ve gotten to. So far, we’ve seen that the risk of injury and illness is complex and multifactorial, with a number of different models helping us to better understand how we might get injured. We’ve discussed the influence of “load”, a broad term which can include physiological, psychological, and lifestyle-related factors. We looked closely at illness and immune function and how psychological and lifestyle-related factors such as poor sleep and anxiety can increase the risk of both illness and injury. Similarly, inadequate nutrition, especially inadequate energy intake, is also a significant risk factor. This article will continue with this last point and take a deeper look at nutrition and energy intake. Read more

Maybe I just remember those colds because they’re linked to an important event I was taking part in, but an increasing body of research shows I was not alone and that athletes become increasingly susceptible to illnesses in the run up to major competitions.
