Researchers investigated how different exercise intensities and patterns affect the immune system's ability to fight chronic inflammation. The study compared moderate continuous exercise, high-intensity continuous exercise, and high-intensity interval training in 16 participants. Scientists measured cytokines - hormone-like molecules that regulate inflammation - to understand which exercise types best reduce chronic inflammation linked to heart disease and diabetes. This research aims to identify optimal exercise prescriptions for preventing age-related diseases and improving healthspan through targeted anti-inflammatory effects.
