What this Trial Is About
Researchers are studying glucose metabolism and its influencing factors during endurance exercise in healthy soldiers. The study focuses on understanding glucose dynamics, sympathetic nervous system activation, and heart rate variability during a standardized military march. This observational research involves a well-screened group of soldiers who undergo regular health checks, making them an ideal population for investigating metabolic responses to physical exertion. Participants will complete a 6 km march carrying 15 kg of equipment while wearing sensors such as continuous glucose monitors and electrocardiography devices. Before and after the march, blood and urine samples will be collected to assess metabolic markers including catecholamine levels. Body composition will be analyzed using bioelectrical impedance, and questionnaires will gather information on fitness, lifestyle, and medical history. Throughout the study, researchers will monitor physiological and metabolic parameters at baseline, during, and immediately after the march. Data collected include glucose levels, heart rate variability, inflammatory biomarkers, cortisol, and lipolysis markers. The study aims to correlate these measurements with physical activity and body composition to better understand glucose regulation during exercise. Participation involves one assessment visit with sample collection, questionnaires, and the march, concluding with removal of sensors and final testing.

Your Study Journey
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - 1 day
Participants undergo baseline assessments including questionnaires, blood and urine sample collection, body composition analysis, and sensor application for physiological monitoring.
1 baseline visit (in-person)
Duration - Approximately 1 hour
Participants complete a standardized 6 km military march carrying 15 kg of equipment while wearing continuous glucose and heart rate monitoring devices to assess metabolic parameters.
1 in-person exercise session
Duration - Same day as exercise
After the march, sensors are removed and additional blood and urine samples are collected to evaluate metabolic and hormonal responses to physical exertion.
1 post-exercise visit (in-person)
