Study Overview
Brief Summary
The current study is a five-arm, single bout program aiming to assess the effects of training volume and intensity of acute resistance exercise on inhibitory control on neurocognitive function with respect to event-related potential in adults aged 20 - 26 years.
Detailed Description
The current study is expected that 175 healthy adults will be recruited and randomly assigned to control group, low volume-moderate intensity, moderate volume-moderate intensity, high volume-moderate intensity, or moderate volume-low intensity group, with 35 participants in each group. Participants will be required to conduct two experiments. The first was the familiarity experiment, which consisted of the experiment description, the familiarity test, and the 6 Repetition Maximum (RM) test. The process lasted about 3 hours. The exercise group was given a warm-up exercise before the intervention, followed by resistance exercise, including Bench Press, Rowing, Deadlift, and Squat, all completed on the Smith machine. After the exercise, the group was given a cool down, while the control group was given 30 minutes of reading. Before and after the intervention, Stroop, event-related potential and fingertip blood lactate were measured, and another fingertip blood lactate was measured 10 minutes after the intervention, which lasted about 3 hours.

Outcomes
Primary Outcomes
Changes In Neuroelectrical Activities: Event-Related Potential Recording and Analysis
Time Frame: 30 minutes each before & after intervention
The continuous electroencephalogram (EEG) activity of each participant will be recorded throughout the entire Stroop task using a Neuroscan Quick-Cap, with 32 Ag/AgCl electrodes arranged following the international 10-20 system (NeuroScan Inc., El Paso, TX, USA). Changes in the neuroelectrical activities before and after the intervention will be examined. The time windows for each ERP component will be determined based on a visual inspection of the averaged grand waveform.
Changes In Inhibitory Control
Time Frame: 30 minutes each before & after intervention
The computerized Stroop test will be administrated to assess participants' inhibitory function, and the changes in Emotional Stroop test performance (i.e., response time and accuracy) before (pre-test) and after (post-test) intervention will be examined.
Secondary Outcomes
- Muscular Fitness Measurements (1RM)-Bench Press(2 hours on the first day)
- Muscular Fitness Measurements (1RM)-Squat(2 hours on the first day)
- Changes In Positive & Negative Affect(5 minutes after pre-test and post-test of Stroop test)
- Muscular Fitness Measurements (1RM)-Rowing(2 hours on the first day)
- Muscular Fitness Measurements (1RM)-Deadlift(2 hours on the first day)
- Changes In Concentration Of Blood Lactate(2 minutes of each time point (Before the pre-test of cognitive test, after the intervention and before the post-test of cognitive test))
