Bicycle Ergometry and Peripheral Hemodynamics: a Pilot Study
Sponsor: ARCIM Institute Academic Research in Complementary and Integrative Medicine
Summary
This study examines how cycling on an exercise bicycle affects blood flow and heart and circulation in 12 healthy adult men. The main measurement is the perfusion index, which indicates how well blood is flowing through the small blood vessels. The study also measures pulse waves, blood pressure, the time it takes for the pulse wave to travel through the body, changes in heart rate, and the relationship between pulse and breathing. In addition, two pulse oximeter systems, Masimo and Nellcor, are compared, as well as measurements taken from the forehead and the finger.

Interventions
Standardized Bicycle Ergometer Exercise
Participants undergo a single standardized bicycle ergometer exercise test in a semi-recumbent position. After a 12-minute resting period, participants exercise for 28 minutes at graded intensities ranging from 30% to 90% of their individual maximum exercise capacity. Exercise intensity is progressively adjusted according to the predefined study protocol. The exercise period is followed by a 16-minute recovery period without physical exercise. Cardiovascular and hemodynamic parameters are continuously or repeatedly recorded throughout the pre-exercise, exercise, and recovery phases.
