Study of How Short, High-Intensity Body-Weight Exercises Affect Energy Use in Healthy Adults Aged 18 to 30

What this Trial Is About

Researchers are evaluating how short, high-intensity body-weight exercises affect energy use in healthy young adults aged 18 to 30 years. The study focuses on measuring resting metabolic rate RMR, total energy expenditure TEE, and excess post-exercise oxygen consumption EPOC using a portable indirect calorimetry system called COSMED K5. The goal is to understand if just one minute of exercise can significantly change energy use and to compare the energy cost of squats, burpees, and plank exercises. Data will be analyzed in relation to body measurements and heart and lung function to improve exercise and rehabilitation recommendations in several medical fields. Participants will perform three types of one-minute exercisessquats, burpees, and plankat maximum effort or sustained position while wearing the COSMED K5 device to record oxygen consumption, ventilation, heart rate, and oxygen saturation. The study includes three phases resting measuring RMR after 15 minutes of quiet sitting, exercise monitoring energy use during one minute of activity, and recovery measuring EPOC immediately after exercise. Environmental conditions like room temperature and humidity will be kept constant, and participants must avoid caffeine, alcohol, and heavy physical activity for at least 24 hours before testing. Participants will undergo screening including ECG, blood pressure, and body composition assessments before the study. During the sessions, energy use and vital signs will be continuously tracked. The main outcome is the difference in energy expenditure before and immediately after exercise, measured within 10 to 15 minutes post-activity. Secondary outcomes include total energy expenditure during exercise. The study will last from September 2025 to December 2026, with all data collected to help design safer and more effective training and rehabilitation programs.
