Enrollment
70
Participants will receive a single session of HIIT, which last for 19 minutes in duration. During the HIIT session, participants will complete 2 minutes stretching warm-up exercise, followed by a video of exercises which will be projected on the screen to facilitate the participants to follow. The exercise in the video involves various combinations of aerobic and core resistance exercise such as squat jump, jump lunge, push up, burpee, mountain climber etc. The exercise involved bodyweight or minimal basic equipment only, the workout to rest ratio is 45 secs: 15 secs. Participants' heart rate will be kept surveillance and to maintain their respective heart rate attained 85% of aged predicted maximal heart rate during the workout period.

RECRUITINGStroop task
Stroop Task is a neurocognitive test for the performance on inhibition control. Participants are shown a series of word colors that are either congruent or incongruent with the color of the word itself. The participant is required to respond to the color of the word and not the word itself.
Time frame: From baseline to 72 hours post intervention
Flanker Task
Flanker Task is a neurocognitive test for the performance on inhibition control. Participants are shown a series of arrows. The participant is to respond to which way the center arrow is pointing; whether it is to the right or to the left
Time frame: From baseline to 72 hours post intervention
Trail making test (TMT)
TMT is a neurocognitive test for the performance on cognitive flexibility. There are part A and part B in the TMT. The time required to completed part A as well as part B would be recorded separately, the difference in time in completing part B and part A (B-A) and the ratio of time in completing part A and part B (B/A) would be used as the interference score.
Time frame: From baseline to 72 hours post intervention
Wisconsin Card Sorting test (WCST)
WCST is a neurocognitive test for the performance on cognitive flexibility. Participants will be presented with four response cards, which are of different geometric properties (number of objects, color of object and shape of objects), and one stimulus card at a time. Participants will be required to sort the stimulus card. There are 30 trials in the test, number of correct sorting will be recorded, and accuracy will be obtained as number of correct sorting divided by 30.
Time frame: From baseline to 72 hours post intervention
Change in accuracy as measured by the 2-back task
2-back task is a neurocognitive test for the performance on working memory. Participants are presented with a sequence of stimuli in character form. The task consists of indicating when the current stimulus matches the one from 2 steps earlier in the sequence. There are 48 trials in the task, the number of correct responses will be recorded. The accuracy will be obtained as number of correct responses divided by 39.
