Purpose The body roundness index is a newly developed geometrically induced body shape index. This study determined changes to BRI in response to exercise administrated in varying doses, and types (aerobic versus resistance). Methods Data was pooled from three exercise interventions (N=600) that included measurements which allowed for BRI calculation. The exercise interventions ranged in prescribed exercise dose and type (aerobic versus resistance). Changes in BRI were calculated and compared to changes in body weight, fat mass, insulin levels, and BRI predicted visceral adipose tissue. Results Although many subjects experienced little or no weight change, the majority of subjects lost body roundness. Although changed BRI was only weakly correlated to changed body fat in women and men, we found a stronger correlation in BRI predicted baseline visceral adipose tissue and exercise induced changed insulin levels Conclusions Although changes in BMI and weight are often the gold standard of providing patients with information in response to exercise, many patients fail to see any change. Changes in BRI reflect an increased improved health and indicate a positive change in body shape, which can motivate patients for continued application of exercise despite no observed weight loss.
