There are evidences studies which show that exercise has beneficial effects on the central nervous system and cognition. Brain derived neurotrophic factor (BDNF) is an important factor affecting cognitive function which has recently interested a bulk trend of effort in the health context. there is no enough information about the effect of aerobic training and also detraining period on memory function and circulatory BDNF in sedentary girl. So، the aim of this study was to investigate the effect of 4 weeks of aerobic training on continuous attention and brain-derived neurotrophic factor and probable mechanisms of this effect (i.e. neurotrophic factors) in sedentary girls. For this purpose, 12 sedentary females (mean age, 1.92 ± 23.90), voluntarily participated in the study and after giving blood samples and continuous attention test, they started their workout exercise under the aerobic protocol which continued for four weeks. At the end, the PASAT test and blood sampling were conducted 24 hours after the last session in order to remove the temporary effects of exercise. To analyze the data, t-test and Pearson's correlation coefficient were applied at a significance level of p≤0.05. The results showed that exercise led to meaningful progress attention scores (p0.05). Generally, the findings of this study indicated that physical activity can improve continuous attention.
