Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Therefore, the objective of the present research protocol is to analyze and compare the effects of an MICT program and an HIIT program on cardiometabolic biomarkers and physical fitness in young adults with obesity.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
HIIT Group
This group will train for 12 weeks
High-intensity interval training intervention
The HIIT group will undergo training for 12 weeks, with a frequency of three sessions per week, completing a total of 36 sessions. Each session will include a 5-minute warm-up and a 5-minute cool-down at 50-60% of maximum heart rate (HRmax). The training protocol will consist of 2-minute high-intensity intervals performed at 90-95% HRmax, corresponding to a Borg rating of perceived exertion (RPE) of 17-18, alternated with 2-minute recovery periods at 70% HRmax (RPE 12-14). A total of five intervals will be completed per session, resulting in an overall high-intensity workload of 18 minutes. All training sessions will be conducted on a stationary cycle ergometer
Educational sessions
In addition, four educational sessions will be conducted to provide dietary recommendations to all participants. These sessions will aim to promote balanced eating habits and to discourage the excessive consumption of ultra-processed foods or alcohol, as these factors could interfere with the intervention outcomes.
MICT Group
This group will train for 12 weeks
Moderate-intensity continuous training intervention
The MICT group will perform moderate-intensity continuous training at 60-70% HRmax, corresponding to an RPE of 12-14, for 35-45 minutes on a stationary cycleergometer. Heart rate and physical activity levels will be continuously monitored in both groups using a chest-strap heart rate sensor (Polar H9, Polar Electro, Finland).
Educational sessions
In addition, four educational sessions will be conducted to provide dietary recommendations to all participants. These sessions will aim to promote balanced eating habits and to discourage the excessive consumption of ultra-processed foods or alcohol, as these factors could interfere with the intervention outcomes.
