XAGE – Exercise and Aging

The XAGE-study is a 6-month physical exercise intervention study. Our study aims to investigate how physical exercise affects different aspects of biological aging, especially how old one appears physiologically, i.e. what is one’s biological age. Secondary aims include the examination of the effects of physical exercise on other phenotypic markers of aging such as functional capacity, physical performance, blood biomarkers, telomere length and epigenetic clocks. We will additionally investigate if some baseline factors such as genetic risk factors are associated with factors describing aging process and physical activity.

The XAGE study is conducted in the metropolitan area in Finland. During 2023–2025 we recruited 150 physically inactive 50–70-year-old adults who don’t smoke and don’t have major chronic diseases.

The XAGE study will provide new data on the effects of physical exercise on longevity and aging by using both established and novel markers of aging and how these are intertwined with each other. We expect that the gained knowledge can be translated into clinical practice and that our study helps to advance the current knowledge on how physical exercise could promote healthy aging in adults approaching later life.
