The study recruited 45 runners to the arduous Lakeland race in the north of England, this 50. And 100-mile . Event takes competitors over very rough terrain with many hill sections, the 2009 event was by thunderstorms and driving rain complicated. All selected runners had been trained specifically for this race marathons and ultra-marathons has been running for over 2 years and had no known heart problems. Due to the extreme conditions and difficulty of the terrain, graduated only 25 of the 45 runners the course and some of them collapsed at the finish in age from 24 to 62, they had taken blood tests for cardiac troponin I, and ECGs were performed before and. – the 50-mile competitors, the average completion time was 15 hours, normal, but there weight loss of 2kg – the 100-mile competitors, the average completion time 36 hours, with an average weight loss of 3 kg – rose Cardiac Troponin I levels in 21 of the 25 runners, and in three, it was high enough to suggest significant cardiac damagethe ECG at the beginning of the race showed the typical characteristics of a sporty heart, with the slow heart rate and electrical changes commonly seen in athletes.
The conclusions indicate that some damage likely to occur on the heart muscle of competitors, while 12 % of the study group showed evidence of significant cardiac damage. – Commenting on the reasons for the research, said Professor John Somauroo the Countess of Chester Hospital, ‘Previous studies on the effects of ultra – endurance training is investigating changes in the shape and function of the heart, but also changes in sensitive marker of cardiac damage including use of cardiac troponin I blood test. However, she did not look like an athlete’s ECG changes in electric, and whether there is a correlation between these and cardiac troponin I.# 13 vitamin D.
