In this episode, we talk with Professor Nicolette Bishop, who is a Professor in Exercise Immunology at Loughborough University (UK). Her research is focused on studying the effects of exercise on inflammation and the immune system.Professor Bishop is also interested in studying infection risk in elite athletes. We speak with her about the interaction between exercise, chronic inflammation, and the immune system in the context of health and disease. We start discussing how exercise impacts inflammation and the immune system and why too much exercise can increase infection risk. We also talk about some studies that suggest that having a high cardiorespiratory fitness (VO2) can reduce the risk of hospitalization due to COVID. We talk about the parameters of exercise that can help reduce chronic inflammation, whether some types of exercise could be more effective than others and how we can monitor the effects of exercise on our immune system.
