The Effect of Acute Concurrent Exercise on Executive Function: An Event-Related Potential Study
Condition: Executive Function
Study type: Interventional

Summary: 
      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.
    

Detailed description: 
      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. 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.
    

Intervention name(s): concurrent exercise; aerobic exercise
Intervention type(s): Behavioral; Behavioral
Intervention description(s): Participants conduct warm up for 5-min, aerobic exercise for 12-min, resistance exercise for 13-min, and 5-min cool down.; Participants conduct warm up for 5-min, resistance training for 25-min, and 5-min cool down.
Allocation: Randomized
Intervention model: Parallel Assignment
Intervention model description: 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.
