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, previous studies indicated that acute exercise could increase the concentration of blood lactate which is positive correlated to executive function. It is still unclear whether the effect of acute concurrent exercise on executive function is mediated by blood lactate. Therefore, the purposes of present study are: (1) Measuring the effect of acute concurrent exercise and aerobic exercise on executive function. (2) Measuring whether the 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, previous studies indicated that acute exercise could increase the concentration of blood lactate which is positive correlated to executive function.

| Task Switch Test Response Times | The shifting aspect of executive function was assessed using a computerised task-switching test. Each participant (N=78) completed 384 trials across six blocks (64 trials per block). The test consisted of two types of cognitive tasks: (1) number magnitude judgment (greater/less than 5) for digits 1-9 presented in solid-line squares, and (2) odd/even judgment for numbers presented in dotted-line squares. Performance was analysed by calculating each participant's mean response time (milliseconds) under four conditions: Homogeneous condition: Blocks where participants performed the same task repeatedly (Blocks 1 & 2, e.g., AAAA or BBBB) Heterogeneous condition: Blocks where tasks were mixed (Blocks 3-6, e.g., AABBAA) Non-switch trials: Consecutive trials of the same task type within heterogeneous blocks (e.g., AA or BB) Switch trials: Trials where the task changed from the previous trial within heterogeneous blocks (e.g., AB or BA) Lower response time represents better task perform | 30 minutes |

| Blood Lactate | The lactic acid system is one of the important systems of human energy metabolism. In addition to supplying energy to muscles, it can also be used as an energy source for brain energy metabolism. When people doing exercise, the concentration of blood lactate will be increased, and the lactate acid system will replace the glucose system as the main energy source for the brain. In the present study, blood lactate were collected from fingertip with a lancet and measured by lactate analyzer before, 17 minutes after, and after intervention. |

Participants were randomly assigned to three group, namely the concurrent exercise group (CE), the aerobic exercise group (AE), and the reading control group (RC). Participants in CE groups were asked to finish 5 min warm-up, 12 min aerobic exercise, 13 min resistance exercise, and 5 min cool down. Participants in the AE group were asked to finish 5 min warm-up, 25 min aerobic exercise, and 5 min cool down. Participants in RC group were required to finish 35 min reading. All groups took a 30 min cognitive test before and after the intervention. The blood lactate were collected before, 17 minutes after, and after the intervention.
