Glucose-Level During Endurance Exercise

As part of the mandatory annual assessment of physical fitness, soldiers are required to complete a standardized military march. A total of 100 healthy volunteer participants will be recruited from soldiers serving at the Bundeswehr Hospital Ulm. During this march, physiological and metabolic parameters will be assessed.

At baseline, anthropometric data and information on medical history, lifestyle, and fitness status will be collected, including a validated questionnaire on physical activity. Blood and urine samples will be obtained to determine routine laboratory and metabolic parameters, and body composition will be assessed using bioelectrical impedance analysis. In addition, selected sensors will be applied to continuously record physiological data.

Participants will then complete a 6 km march carrying 15 kg of equipment. After completion of the march, sensors will be removed and additional blood and urine samples will be collected to evaluate metabolic responses to physical exertion, including catecholamine levels.
