A new research has revealed that young adults, mainly women, who maintained high levels of moderate and vigorous activity over a period of 20 years experienced smaller gains in weight and waist circumference during the transition from young adulthood to middle age, compared to individuals with lower activity levels.

Arlene L. Hankinson, of the Feinberg School of Medicine, Northwestern University, Chicago, and colleagues conducted a research to evaluate the relationship between maintaining higher activity levels and changes in body mass index (BMI) and waist circumference over 20 years in youthful adults.
