Executive function is a high-level cognition which plays an important role in our life. Meta-analysis study has demonstrated that acute exercise could improve executive function. However, it is still unclear whether executive function can be enhanced by the concurrent exercise that combines aerobic and resistance exercise. Moreover, the sequence of concurrent exercise may result in different blood lactate concentration which may affect executive function. Therefore, the purposes of present study are: (1) Measuring the order effect of acute concurrent exercise on executive function. (2) Measuring whether order effect of acute concurrent exercise on executive function is mediated by blood lactate.
Executive function is a high-level cognition which plays an important role in academic performance, career, and interpersonal relationship. Meta-analysis study has demonstrated that acute exercise could improve executive function, and also observed similar positive effect through both aerobic and resistance exercise. However, it is still unclear whether executive function can be enhanced by the concurrent exercise that combines aerobic and resistance exercise. Moreover, the sequence of concurrent exercise may result in different blood lactate concentration which may affect executive function. Therefore, the purposes of present study are: (1) Measuring the order effect of acute concurrent exercise on executive function. (2) Measuring whether order effect of acute concurrent exercise on executive function is mediated by blood lactate.

Stroop test
The Stroop task consists of neutral, congruent, and incongruent trials. In neutral trials, colored rectangles were presented and participants were instructed to respond to whether the squares were red, blue, or green. For congruent and incongruent trials, participants were presented with the names of the three Chinese color words of 紅 (red), 藍 (blue), or 綠 (green) printed in either the same (congruent) or different (incongruent) ink color and instructed to respond to the color of the ink while inhibiting the meaning of the word.
Time frame: 30 minutes
task switch test
The shifting aspect of executive function was assessed by means of a computer version of the task-switching test. In brief, each participant was presented with six blocks of 64 trials. For the first block, the participant was required to identify whether the stimulus (i.e., digits 1-9, without digit 5) within the solid-line square was greater/less than the digit 5. For the second block, the participant identified whether the stimulus within the dotted-line square was even/odd. The blocks 3-6 consisted of an equal number of stimuli from the first and second blocks forming an alternating-runs paradigm.
