EFFECT OF HIGH INTENSITY INTERVAL TRAINING VERSUS LOW INTENSITY CONTINOUS TRAINING ON PHYSICAL FITNESS AMONGOVERWEIGHT ADULT

Abstract

Objective: The Study aimedto compare between the effect of high intensity interval training versus low intensity
continous training on physical fitness among overweight adult. Methods: Clinical trial,thirty overweight subjects from
both sexes with age range from 20 to 30 yearsoldselectedfromHorusUniversityinNewDamiettacity participated in the
study for 12 weeks 3sessions/week and were divided randomly into two groupsofequalnumbers (A&B): Group
A:subjects in this groupparticipated in sixty-minutes high-intensity interval training exercises 3 times per week for a
period of 2 successive months.Group B: subjects in this groupparticipated in 60-minutes low-intensity training exercises
three times per week for a period of 2 successive months. All subjects were assessed by weight and height scale (BMI),
pulse oximeter, the waist circumference (WC),waist hip ratio (WHR), bioelectrical impedance analysis, a mercury
sphygmomanometer, VO2max and the 20-meter shuttle run test (20mSRT).Results: Comparing both groups pre-study
and post-study revealed statisticallysignificant improvement in all measured variables (P<0.05) in both groups, with
higher percentage of improvement in favor to group A.
Conclusion: Bothhigh intensity interval training and low intensity continous training have an effect on
improvingVO2max and reducing fat mass percentage with higher percentage of improvement in favor to group A.
