This study will be conducted to investigate any significant effect of high intensity interval training on metabolic syndrome severity score in women with central obesity.

RESPONSE OF METABOLIC SYNDROME SEVERITY SCORE TO HIGH INTENISTY INTERVAL TRAINING IN WOMEN WITH CENTRAL OBESITY

forty eight women with age ranges from 25 to 45 years old will be selected from nutrition-outpatient clinic; they will participate in the study for 6 weeks, and randomly be assigned into two equal groups.

Study group A (n =24) will receive low volume High-intensity interval training (HIIT) three times /week for 6 weeks , study group B (n =24) will receive caloric restriction diet

For evaluation Physical efficiency index using Modified Harvard Step test It is a powerful indicator for aerobic fitness. The Fitness Index score is determined according to the following equation

Fitness Index (long form) = (100 x test duration in seconds) divided by (2 x sum of heart beats in the recovery periods).

Metabolic syndrome severity score Metabolic syndrome severity score will be calculated through MetS Calculator (MetSCalc).
