HIIT Vs Snack Exercises on the Academic Stress of University Students

"The high-intensity interval training (HIIT) protocol will run for 12 weeks, with two weekly sessions, totaling 24 sessions. Each 20-minute session will follow a group-based circuit format with functional exercises (e.g., jogging, jumping jacks, step-ups). High-intensity phases will be performed at maximum effort, while moderate-intensity phases will be maintained at a Borg scale rating of 4-6.~Training will amount to 40 minutes per week. The intensity ratio will progress over time:~* Weeks 1-4: 15 sec high / 60 sec moderate (1:4)~* Weeks 5-8: 15 sec high / 45 sec moderate (1:3)~* Weeks 9-12: 15 sec high / 30 sec moderate (1:2)~* Weeks 13-16: 15 sec high / 15 sec moderate (1:1)~This progressive structure ensures gradual adaptation while maximizing effectiveness."

The exercise snack protocol will last for 12 weeks, with sessions held twice a week, totaling 24 sessions. The exercise snacks will amount to 40 minutes per week, divided across the five weekdays. Participants will be required to perform 4 minutes of functional exercises (e.g., jogging in place, jumping jacks in place, modified burpees in place, etc.) in both the morning (AM) and evening (PM), completing a total of 8 minutes per day. The exercises must be performed at high intensity, with a score of \>8 on a modified Borg scale.
