What this Trial Is About

Introduction This study investigates the effects of different intensities of indoor cycling on various health measures. Participants will perform a maximal cycling test to determine their maximal fitness - a strong predictor of overall health - before and after a 6-week training intervention. Blood samples will also be obtained to look at various physiological markers related to extracellular vesicles, inflammation, and metabolism. Who can participate? Healthy young adults who between 18 and 40, are free of immune disease, with a normal body mass index can join this study. They will be divided into three groups: * One group will ride a bike at a moderate pace. * Another group will ride a bike at a slightly harder pace. * The third group won't change their usual daily activities and will continue living as they normally do. What does the study involve? Each exercise session aims to burn a specific amount of calories: 350 for males and 300 for females. Participants cycle 3 times a week for 6 weeks. At the end, we'll repeat the bike test and take another blood sample to see if there have been any changes due to the exercise. Why is this research being done? The researchers want to see how different intensities of exercise impact health and fitness. This may help people make better choices about how much and what type of exercise they should do. What happens after the study? Researchers will analyze the data from the study and see if any differences exist between the protocols. If the participant is interested, we will also provide their blood test results, and the results from their max test.
