Over the past month Polly Baker, Alan Richardson, Todd Leckie, Emily Watkins and a team of twenty BSc and MSc students have been busy testing 165 Brighton Marathon runners in the labs, at the marathon exhibition and immediately after the race. Two weeks before the marathon, running economy and VO2max tests were completed on fifty of the runners at Welkin Labs, to calculate cardiovascular fitness. Runners then wore heart rate monitors throughout the race to calculate running intensity. These fifty runners plus eighty-five healthy runners and fifteen with structural heart disease had a marker of heart damage called cardiac troponin T measured at the marathon exhibition and immediately after the race in the medical tent. A further 20 runners that collapsed during the race also consented to having bloods measured. This research work will now be used to identify the amount of cardiac stress and damage that occurs during the marathon. The sub groups and exercise data will be used to identify whether this cardiac stress response and the chance of collapse can be predicted by certain exercise or demographic measures. Over the next few months the data will be analysed and written for two publications. The team would like to thank the support of the Brighton Marathon, BASEM, SESAME, the SES students and the technical support staff in making the project a success.
