Aerobic training suppresses exercise-induced lipid peroxidation and inflammation in overweight/obese adolescent girls.

This study aimed to determine whether aerobic training could reduce lipid peroxidation and inflammation at rest and after maximal exhaustive exercise in overweight/obese adolescent girls. Thirty-nine adolescent girls (14-19 years old) were classified as nonobese or overweight/obese and then randomly assigned to either the nontrained or trained group (12-week multivariate aerobic training program). Measurements at the beginning of the experiment and at 3 months consisted of body composition, aerobic fitness (VO2peak) and the following blood assays: pre- and postexercise lipid peroxidation (15F2a-isoprostanes [F2-Isop], lipid hydroperoxide [ROOH], oxidized LDL [ox-LDL]) and inflammation (myeloperoxidase [MPO]) markers.

Body mass index and body fat in Lebanese female adolescents.

Objective: The aim of this study is to investigate the relation between body mass index (BMI) and body fat (BF) among Lebanese female adolescents.

Methods: 51 Lebanese females aged 12 to 18 years participated in this study. BMI was calculated as weight/height.

Activity, inactivity and quality of life among Lebanese adolescents.

Background: The aim of the present study was to investigate recent overweight and obesity prevalence rates for Lebanese adolescents, and to examine differences in physical activity, screen time (sum of time spent in front of TV, computer, and videogames), and health-related quality of life (HRQOL) for the first time among normal, overweight, and obese adolescents.

Methods: One thousand Lebanese adolescents (14-18 years old) from nine schools participated in the study. Height, weight, physical activity, screen time, and HRQOL variables were assessed using validated self-report questionnaires.
