Effectiveness of Long Interval VS Medium Interval High-Intensity Interval Training on Cardio-Respiratory Fitness among the Obese Collegiate – Comparative Study

The prevalence of overweight and its related diseases has increased worldwide in the recent population.In contrast with the accumulation of peripheral subcutaneous fat, excessive fat accumulation in the abdominal viscera is strongly associated with obesityrelated complications.College is a transitional period from adolescence to adulthood and also a crucial period for the development of healthy lifestyles and the formation of healthy behaviors.High-intensity interval training could be beneficial for the enhancement of cardiovascular endurance among collegiate obese.AIMS: The purpose of this study is to compare the effect of long-interval and medium-interval HIIT training on BMI, Rate of perceived exertion (RPE), and 6-min walk test distance (6MWTD) on obese collegiate.METHODS: A Quasi-experimental study design with 30 Students of SRMIST, Kattankulathur, aged 18-30 years and BMI > 25 Kg/m 2 (Asian criteriabased) who were divided into two groups (Group A-HIIT long interval × 3/week n=15, Group B-medium interval × 3/week n=15) for 8 weeks was employed.OUTCOME MEASURES: The study was conducted by using the Body mass index, and Borg scale and measuring distance by using a 6-min walk test.RESULTS: The study concluded that there is no significant difference between the long and medium intervals of High interval intensity training.However aerobic capacity and level of rate of perceived exertion moderately improved in both groups (p<0.05), and the body mass index somewhat decreased after 8 weeks of intervention.CONCLUSION: These new findings show that exercising three times with HITT per week improves cardiorespiratory fitness, body mass index, and rate of perceived exertion in overweight/obese college students, but there is no significant difference between the intervals (long and medium).The interval of HIIT may be a viable and effective method for prescribing an initial fitness program overweight collegiate.
