This experimental condition involves engaging in physical activity interspersed with rest periods based on cognitive tasks.

This experimental condition involves engaging in physical activity interspersed with rest periods (without cognitive tasks).

In this condition, participants will be suggested to watch a video while seating/resting for 10 minutes.

This experimental condition will follow the following structure: involving 10 consecutive, 30 second-blocks of physical activity. This experimental condition will focus on aerobic metabolism. The total exercise time commitment is 10 minutes (30 seconds of working - 30 seconds of executing an engaging cognitive task, 1:1 work-to-rest ratio), plus 5 minutes of warm-ups and 5 minutes of cool-down activities. The cognitive task consists of solving various "tangrams".

In this research, only the general academic fluency index was administered, consisting of the reading, mathematics, and writing fluency subtests. Reading fluency assessed the participant's capacity to read simple sentences rapidly, mathematical fluency gauged the ability to quickly solve simple addition, subtraction, and multiplication problems, and writing fluency measured the skill to formulate and write sentences promptly.

Flanker Test: Assessed inhibitory control of irrelevant stimuli. Congruent stimuli facilitated processing, while incongruent ones hindered it.

n-back Test: Evaluated working memory's information updating. Participants matched stimuli to the one 'n' items ago, with increasing difficulty.

Conners CPT-3 Attention Test: Examined sustained attention with 360 trials, 18 blocks, and varying intervals. 90% featured non-X target stimuli. Assessment included scaled scores for attentional capacity (d'), error categorization, and reaction metrics.

Event-related brain potentials (ERPs), acquired from the electroencephalogram, served as a metric for brain response to discrete events. Neuroelectric activity was captured from 14 scalp electrode sites, arranged using the EMOTIV EPOC X and its corresponding software. Selected components of event-related brain potentials were assessed, with a focus on analyzing the amplitude and latency of P3 (also referred to as P300). A higher P3 amplitude was considered indicative of an enhanced ability to enlist attentional resources, while a lower P3 latency was considered indicative of heightened cognitive processing speed. In study I, ERPs were concurrently recorded during cognitive function (not CPT-3).

Were measured using the ALPHA Physical Fitness Test Battery.

Were assessed using Actigraph wGT3X-BT accelerometers, which participants carried throughout their four-week involvement in the project. Additionally, sedentary lifestyle levels were gauged using the Youth Activity Profile (YAP).
