Effects of daily walking on intermuscular adipose tissue accumulation with age: a 5-year follow-up of participants in a lifestyle-based daily walking program

Purpose Intermuscular adipose tissue (IMAT) accumulates with age. However, there has been no long-term intervention study examining whether daily walking prevents or decreases the age-related IMAT accumulation. The purpose of this study was to determine effects of a long-term lifestyle-based daily walking program on age-related IMAT accumulation after a 5-year follow-up.
