Aim: Brain derived neurotrophic factor (BDNF) and physical inactivity contribute to the development of metabolic syndrome (MetS). Aerobic training has been reported to improve MetS, however less attention has been directed toward the role of training and detraining on cognitive function in MetS.
Methods: Twenty one healthy middle-aged males and 21 with MetS were distributed into four groups: MetS exercise (ME), MetS control (MC), Healthy exercise (HE) and healthy control (HC). Both ME and HE, followed a 6-week aerobic training program (3 sessions/week). Digit Span memory test and blood sampling were conducted pre training, post training andalso following a six weeks detraining. Data were analyzed using spearman, pearson and repeated measure ANOVA tests.
Results: Baseline serum BDNF level was positively correlated with waist circumference (r=0.383, P=0.012) and showed significant elevation in MetS compared with healthy subjects (1101.66±61.34 vs. 903.72±46.57 pg/mL, P=0.014). After aerobic exercise BDNF level significantly increased in HE, but decresed in ME group (P=0.001). Both short and mid term memory significantly increased (P<0.05) only in HE group.
Conclusion: Exercise induced cognitive improvement might be mediated via BDNF-linked mechanismsin healthy people. However, the health status of individuals should be considerd.
