Comparsion Effect of High Intensity Interval Training Vs Low Intensity Interval Training On Obesity Reduction In College Students

Back ground : Overweight and obesity are defined as abnormal or excessive fat accumulation that presents a risk to health. A body mass index (BMI) over 25 is considered overweight, and over 30 is obese. In 2019, an estimated 5 million non-communicable   disease (NCD) deaths were caused by higher-than-optimal BMI.Rates of overweight and obesity continue to grow in adults and children. From 1990 to 2022, the percentage of children and adolescents aged 5–19 years living with obesity increased four-fold from 2% to 8% globally, while the percentage of adults 18 years of age and older living with obesity more than doubled from 7% to 16%.

Obesity is one side of the double burden of malnutrition, and today more people are obese than underweight in every region except the South-East Asia Region. Once considered a problem only in high-income countries, today some middle-income countries have among the highest prevalence of overweight and obesity worldwide.

High-intensity interval training (HIIT) refers to an exercise program that is characterized by relatively short bursts of vigorous activity, interspersed by periods of rest or low-intensity exercise for recovery.

Low-Intensity Interval Training (LIIT) Low-Intensity Interval Training (LIIT) is a form of exercise that involves alternating periods of low-intensity activity with periods of rest or very low-intensity activity. Low intensity interval training (LIIT) consists of periods of low impact exercise performed in intervals combined with longer periods of rest than you might have with a HIIT (high intensity interval training) workout. LIIT is ideal for people who are older, new to exercise, or recovering from an injury

Method : In this parallel group RCT study , 62 participants aged 18-25 years with obesity people from college students in Bangalore will be enrolled in a 4 weeks exercise program . Through simple random allocation , they will be randomized

Main Outcome measures: The main outcome will BMI , waist circumference

Data analysis: The results will be analysed using descriptive statistics , paired t test for finding the effectiveness within groups and unpaired t test for finding the effectiveness between the groups.
