However, men saw more benefit from physical activity than women. BMI, which stand for body mass index, is a measurement of body fat based on a calculation of height and weight. A large, longitudinal studyIn 1986 researchers asked over 7,000 Norwegian men and women between age 55 and 69 about their height, current weight, and weight at age 20. Both genders also told researchers about their current physical activity, which included dog walking, gardening, home improvements, walking or biking to work and sports. The men and women were then sorted into daily activity quotas: less than 30 minutes, 30 to 60 minutes, and 90 minutes or more.
