We thank Dr. Zhang [1] for his interest in our literature
review about the effects of resistance training (RT) programs
in obese adolescents [2]. In the review, we analyzed
21 studies to evaluate the impact of RT on body mass
index, body fat, waist circumference, lean mass, insulin
sensitivity, muscle strength, and cardiorespiratory fitness.
Our main findings showed that RT programs seem
to be positive for obese adolescents, improving muscle
strength and cardiorespiratory fitness and reducing body
fat, waist circumference, and body mass index. Yet, we
were clear to advise the reader that the results should be
carefully analyzed, and some limitations were addressed,
for example, (i) the small number of participants in each
study; (ii) the use/comparison of different training programs
(i.e., varying durations, intensities, and exercises);
(iii) methodological issues (i.e., with an unclear or high
risk of bias); (iv) unclear dietary control of participants;
and (v) maturational-related issues. We understand that
these limitations should not refrain professionals from
critically appreciating our results and then designing RT
programs for obese adolescents.
