Combined exercise is a suitable and varied activity to control weight and strengthen children's respiratory muscles. The aim of the present study was to investigate the effect of combined rope and basketball training on body composition and some indicators of pulmonary function of overweight boys aged 10-12 years.

This article was a quasi-experimental study with a pre test-post test design with a control group. For this purpose, 30 overweight male students were purposefully selected and randomly divided into two groups of 15 experimental and control. Respiratory parameters were measured by spirometry and body composition factors before and after exercise. Subjects participated in a training program for 6 weeks. Data analysis was performed using analysis ANCOVA and dependent t-test in SPSS-20 software.

Exercise intervention in the experimental group caused a significant reduction in weight, fat percentage and body mass index compared to the control group (p<0.05). Forced Vital Capacity and Forced Expiratory Volume in one-Second pulmonary function indices have had a significant increase (p<0.05).

Combined basketball and rope training exercises are effective in improving body composition and increasing the performance of overweight students' lung characteristics.
