The purpose of this study was to investigate the effects of group exercise on physical fitness and psychoneuroimmunological factors in female adolescents. Thirty-three female adolescents were divided into three groups, control (CON; n = 11), running exercise (RE; n = 11), and group exercise (GX; n = 11) for 12 weeks of the exercise intervention. For all subjects, measurements of body composition, cardiovascular function, psychological factors, and serum neuroimmunological factors were completed before and after the 12-week intervention. First, the changes in mental stress were significantly lower in RE and GX compared with the CON group, and it was significantly decreased following the exercise intervention in RE and GX groups. Although there was no significant difference in the level of change between groups in depression and self-confidence, it was only reduced following GX intervention in GX group. The changes in peak oxygen uptake and exercise time were significantly greater in the RE and GX compared to the CON group, and it was increased after exercise intervention in RE and GX groups. The changes in percentage of body fat(BF%) were significantly lower in the GX compared to the CON group. The changes in lean body mass(LBM) were significantly greater in RE and GX compared to the CON group. Moreover, BF% was decreased whereas LBM was increased in the GX group after the exercise intervention. Finally, the changes in tumor necrosis factor alpha were only reduced in the RE group, resulting in significantly lower changes compared with CON and GX groups. More interestingly, although no significant differences were found between groups, brain-derived neurotrophic factor(BDNF) was increased following the exercise intervention in the GX group only. These findings demonstrate that GX will result in decreased BF% and increased LBM, and cardiovascular function. In addition, GX significantly decreases stress, and depression, but increases self-confidence and BDNF. Collectively, this indicates that 12 weeks of GX intervention can have a positive effect on body composition, physical fitness, and neurological function, which may contribute to improvements in psychological factors in female adolescents.
