As COVID-19 continues to disrupt our lives, endurance athletes are faced with challenges – how to maintain their fitness level and their immune health. Previous Performance Tips have discussed the beneficial effects of exercise on immune function. A recent study examined the impact of intermittent fasting, which has become quite popular among endurance, on immune function.

Much of the research correlating sleep loss and impaired performance has focused on the impact of cortisol, the body’s primary stress hormone.

Last Performance Tip highlighted a multi-study analysis on the ketogenic diet and exercise performance. The overall conclusion was the ketogenic diet did not improve endurance performance. The problem with a multi-study is that the individual studies lacked protocol uniformity and subject selection. For that reason, these types of analysis are always opened to criticism. That's why a recent well designed study by a respected exercise scientist, should be of great interest to ketogenic diet aficionados...

There is strong evidence that chocolate, because it contains a high concentration of flavonoids, has anti-inflammatory activity. Besides chocolate, flavonoids are found in berries, vegetables, tea and coffee. Two recent studies examined whether chocolate flavonoids could reduce post exercise inflammation...
