Effect of concurrent training on inflammatory status and physical fitness of inactive adolescent girls has less beenstudied. The purpose of this study was to survey effect of four- and eight-week concurrent training on inflammatorymarkers, muscular strength, and cardio respiratory function in inactive adolescent girls. In a semi-experimentalstudy, twenty three inactive adolescent girls were randomly placed at two groups: training (n=11, 17.07±0.28 yr,53.45±8.7 kg, 20.98±3.9 kg/m2) and control (n=12, 17.16±0.25 yr, 56.50±9.1 kg, 21.44±3.1 kg/m2). Generalcharacteristics of subjects and serum levels of inflammatory markers C-reactive protein (CRP) and tumor necrosisfactor-alpha (TNF-α) were assessed before and after fourth and eighth weeks of training period. Concurrent trainingprotocol was included eight weeks rhythmic aerobics and weight training (3 sessions per week, aerobics withintensity 60-75% of maximum heart rate and duration of 15-30 min and weight training with intensity of60-70% ofone repetition maximum and duration of 25-55 min per each session). Data were analyzed by two-factor ANOVAwith repeated measures test.Statistical significance was accepted at P<0.05. Body weight, body mass index, bodyfat percent, and serum concentrations of CRP and TNF-α didn't change after training period. Muscular strength andcardio respiratory function were increased at end of fourth week, and more, eighth week of training period (P<0.05).Performing concurrent training has no effect on anthropometrics and inflammatory markers of inactive adolescentgirls, while improved the health-related physical fitness and this improvement was more following eight- than fourweektraining.
