[Physical activity measured with accelerometers].

The development of accelerometers has revolutionized measurement of physical activity, and they are used to a large extent in research and have started to be implemented into clinical settings. However, achievement of reliable outcomes requires good methodological knowledge and skills by the user. Otherwise, significant measurement errors may occur, interfering with assessment of the physical activity level in the population, group differences, associations with health parameters or effect of treatments.

[Biochemical changes after strenuous exercise – data from the Kalmar Ironman].

Biochemical changes after strenuous exercise - data from the Kalmar Ironman Strenuous and prolonged exercise like marathon, ultra running and triathlon can lead to changes in biomarkers of cardiac, muscle and kidney functional damage. We present the data of 30 (15 men, 15 women) participants of the Kalmar Ironman 2015. Pre-race electrocardiograms and echocardiograms showed a high frequency of abnormalities.
