The main question it aims to answer are:Question 1: Whether a single bout of 20-min MF-HIIT has larger beneficial effect on EF performance than that following a 20-min session of MF-only and HIIT-only in relative to the sitting restQuestion 2: Whether a single bout of 20-min MF-HIIT has a larger beneficial effect on brain functioning, as measured by the N2 and P3 components of event-related potential (ER) during EF performance than that following a 20-min session of MF-only and HIIT-only in relative to the sitting restParticipants will visit the laboratory on 5 separate days (\> 2-day washout between days) in which they have not previously participated in structured physical activities.Participants will complete the testing and/or receive treatments below:Day 1:* Kaufman Brief Intelligence Test (KBIT) to assess intelligence quotient* Treadmill-based exercise test to measure cardiorespiratory fitness (maximum oxygen consumption)Days 2-5* Each day, participants will complete each of the four intervention conditions (MF-HIIT, MF-only, HIIT-only, sitting)* Participants' heart rate and self-reported affect and rating of physical exertion will be measured* Participants will complete a modified flanker task and a task-switching task to assess inhibitory control and cognitive flexibility* Participants will wear an EEG cap to measure the N2 and P3 components of the event-related potential during the inhibitory control and cognitive flexibility performanceResearcher will compare the cognitive outcome measures following the MF-HIIT, MF-only, and HIIT-only conditions with the sitting condition to see if MF and HIIT has beneficial effects on children's EF.Further, researcher will compare the cognitive outcome measures following the MF-HIIT compared with MF-only and HIIT-only conditions to see if combining MF with HIIT has greater beneficial effects on children's EF than MF and HIIT alone., conditionsModule conditions: Healthy Volunteers, designModule studyType: INTERVENTIONAL, phases: NA, designInfo allocation: RANDOMIZED, interventionModel: CROSSOVER, primaryPurpose: BASIC_SCIENCE, maskingInfo masking: SINGLE, whoMasked: OUTCOMES_ASSESSOR, enrollmentInfo count: 60, type: ESTIMATED, armsInterventionsModule interventions name: MF-HIIT, interventions name: MF-only, interventions name: HIIT-only, interventions name: Sitting rest, outcomesModule primaryOutcomes measure: Inhibition speed, primaryOutcomes measure: Inhibition accuracy, primaryOutcomes measure: Shifting speed, primaryOutcomes measure: Shifting accuracy, primaryOutcomes measure: N2-ERP, primaryOutcomes measure: P3-ERP, secondaryOutcomes measure: State Mindfulness Scale for Physical Activity (SMSPA), secondaryOutcomes measure: Rating of perceived exertion, secondaryOutcomes measure: Heart Rate, otherOutcomes measure: Dispositional mindfulness, eligibilityModule sex: ALL, minimumAge: 10 Years, maximumAge: 12 Years, stdAges: CHILD, contactsLocationsModule, hasResults: False
