Response of agrin, mTOR and AKT proteins in dual resistance-cognitive exercises of healthy people

Introduction: Considering the importance of agrin, mTOR and AKT proteins in cognitive and physiological function, knowing the effects of different exercise programs is of particular importance. Aim: The purpose of this study was to investigate the responses of agrin, mTOR and AKT proteins in dual resistance-cognitive exercises of healthy people. Method: The research method is semi-experimental. 10 healthy men were randomly divided into two groups (resistance-cognitive group of 5 people and resistance group of 5 people). Resistance contraction included eccentric and concentric knee extension with maximum strength and speed. The contractions included 12 sets of 10 repetitions for the right leg, and in the cognitive group, cognitive task exercises included counting numbers in reverse, multiplying and dividing numbers, counting the months of the year, and counting coins simultaneously with facial resistance exercises. Took A biopsy was performed at the beginning and end of the study. To analyze the data, dependent t statistical method and covariance test were performed in SPSS21 software. Results: The results showed that the intra-group changes of mTOR and AKT proteins after one activity session were significant in the resistance-cognitive and resistance groups (p≤0.05). However, the inter-group changes of agrin, mTOR and AKT proteins showed no difference between the two groups. Conclusion: The present study showed that a session of resistance and resistance-cognitive activity leads to changes in the factors involved in the strength and hypertrophy of skeletal muscles. In addition, these changes are generally more resistance-cognitive in the resistance group.
