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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes In Inhibitory Control | 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. |
| Changes In Neuroelectrical Activities: Event-Related Potential Recording and Analysis | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Muscular Fitness Measurements (1RM)-Bench Press | 2 hours on the first day | The greatest weight an individual is capable of lifting for one repetition (1RM) will be examined using the 6-RM assessment according to the American College of Sports Medicine (ACSM) protocol. There were multiple steps in the resistance exercise assessment process. Warming up at a low intensity for 1 minute will be followed by a 1-minute rest break. For the first set of exercises, each person's workload (lbs) will be increased by 5-10%. Participants will be told to do 10 repetitions followed by a 2-minute rest break during this step. Following that, a steadily increasing load will be applied until the load can only be completed less than 6 repetitions. The numbers of set will be limited to the minimum 1set to maximum 4sets. 1RM will be caculated by the results of 6-RM protocol. |
| Muscular Fitness Measurements (1RM)-Squat | 2 hours on the first day | The greatest weight an individual is capable of lifting for one repetition (1RM) will be examined using the 6-RM assessment according to the American College of Sports Medicine (ACSM) protocol. There were multiple steps in the resistance exercise assessment process. Warming up at a low intensity for 1 minute will be followed by a 1-minute rest break. For the first set of exercises, each person's workload (lbs) will be increased by 10-20% for. Participants will be told to do 10 repetitions followed by a 2-minute rest break during this step. Following that, a steadily increasing load will be applied until the load can only be completed less than 6 repetitions. The numbers of set will be limited to the minimum 1set to maximum 4sets. 1RM will be caculated by the results of 6-RM protocol. |
| Changes In Positive & Negative Affect | 5 minutes after pre-test and post-test of Stroop test | The changes in the Positive & Negative affect after pre-and post-test will be assessed by The Positive and Negative Affect Schedule (PANAS) questionnaire, which is made up of two 10-item scales that assess both positive and negative emotions. Each item is scored on a scale of 1 (not at all) to 5 (very much). |
| 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) | Fingertip Blood samples will be collected using Lactate Analyzer in three times point: before the pre-test of cognitive test, after the intervention and before the post-test of cognitive test, and analysed the change in concentration of blood lactate between the three time points. |
| Muscular Fitness Measurements (1RM)-Rowing | 2 hours on the first day | The greatest weight an individual is capable of lifting for one repetition (1RM) will be examined using the 6-RM assessment according to the American College of Sports Medicine (ACSM) protocol. There were multiple steps in the resistance exercise assessment process. Warming up at a low intensity for 1 minute will be followed by a 1-minute rest break.

There were multiple steps in the resistance exercise assessment process. Warming up at a low intensity for 1 minute will be followed by a 1-minute rest break. For the first set of exercises, each person's workload (lbs) will be increased by 10-20% for lower body exercises. Participants will be told to do 10 repetitions followed by a 2-minute rest break during this step. Following that, a steadily increasing load will be applied until the load can only be completed less than 6 repetitions. The numbers of set will be limited to the minimum 1set to maximum 4sets.
