There is growing body of evidence to suggest that the use of bioactive foods can be beneficial in the management of post-exercise declines in muscle function. Specifically, foods and their analogues (juice and concentrates) have been shown on numerous occasions to facilitate recovery following strenuous exercise that results in loss of muscle function, inflammation, increased skeletal muscle damage indices and oxidative stress. These interventions show promise for exercise recovery, as indicated in the recent IOC consensus statement on nutritional supplements for elite athletes, but there is some debate in the community that the longer-term use of such interventions might have a mal-adaptative impact or reduce the adaptative potential of exercise.
Foods with high levels of anthocyanins and other polyphenols have anti-inflammatory and antioxidative properties, which have the potential to manage the negative effects of strenuous exercise. However, the inflammatory and oxidative stress imposed by exercise is thought to be a critical process in adaptation. Although there is good evidence to show that these processes (particularly the exercise-induced inflammatory response) can be reduced with the dietary interventions, there are no data that have examined the longer-term implications of supplementation on the adaptative response to exercise. Given that available data using anti-oxidative supplementation (vitamin C & E) has shown that the adaptative response does not appear to be mal-adaptive, we hypothesise that fruit-derived polyphenols will also not attenuate the adaptive response to a training stimulus. Therefore, the aim of this course of research will be to examine the effects of polyphenols rich fruit on the adaptive response to acute and chronic training stimuli.
Northumbria University has a global reputation for high quality work in understanding the stress-recovery-adaptation continuum. In addition, we have demonstrable excellence in the area of polyphenol-rich foods in the application of exercise recovery and performance that is coupled with a strong supervisory team with reputation for delivering high quality doctoral students.
