abstract = {The objectives of this secondary analysis are (1) to investigate the di erential e ects of
exercise training modalities–high-intensity interval training (HIIT), resistance training (RT), combined
training (CT = HIIT + RT), and/or nutritional guidance (NG) alone–on local fat/lean mass indexes in
adults with excess of adiposity; (2) to identify the individual patterns of response based on either a
clinical criterion of weight loss ( 5%) and/or technical error (TE) of measurement of local fat/lean mass
indexes; and (3) to assess the individual change for body composition parameters assigned either
to HIIT, RT, CT, and/or NG groups utilizing a TE. A 12-week trial was conducted in 55 participants
randomized to one of the four interventions. The primary outcome was clinical change in body
weight (i.e., weight loss of  5%). Secondary outcomes included change in ratio of android and
gynoid fat mass, as well as local fat and lean mass indexes (arms, trunk, and legs), before and after
intervention. The main findings from the current analysis revealed that (i) after 12 weeks of follow-up,
significant decreases in several body composition indexes were found including body weight, arm,
trunk, and legs fat mass, and android and gynecoid fat mass were observed in HIIT, RT, and CT
groups (p < 0.05); (ii) a significant proportion of individuals showed a positive response following
12 weeks of training, led by the HIIT group with 44% and followed by RT with 39% in 9 indexes;
(iii) the HIIT group showed lowest rates of adverse responders with (6%); and (iv) the individual
patterns of response utilizing clinically meaningful weight loss were not necessarily associated with
the corresponding individual training-induced changes in body composition indexes in adults with
excess of adiposity. Overall, the study suggests that HIIT has an important ability to reduce the
prevalence of non-response to improve body composition indexes.},
