Abstract
Background: Obesity and overweight is a global health challenge that is rapidly growing from commencement of 21th century. Obesity is related to chronic diseases such as cancer, type 2 diabetes, atherosclerosis, arthritis, liver and kidney diseases, sleep apnea and mental disease and increases risk of all-cause mortality. Different anthropometric indices such as body mass index (BMI), waist circumference (WC), hip circumference (HC), waist to hip ratio (WHR), neck circumference (NC) and thigh circumference (TC) are used for ease of obesity and overweight evaluation. Some of these indices are important in aesthetics such as WC, HC, WHR and TC. Because of low time and high intensity, high intensity interval trainings (HIT) are novel running trainings that may be an appropriate selection by different persons for improvement of their health.
Aim: The aim of this study was to investigate the effects of eight weeks HIT on cardiorespiratory fitness and aforementioned anthropometric indices in young females with overweight.
Methods: Subjects assigned into two groups of control (N=8) and experimental (N=8). Subjects in experimental group performed a selected HIT training for eight weeks (three sessions per week, each session between 45 to 60 minutes) with intensity of 90% of maximum heart rate. Subjects cardiorespiratory fitness (time of Rockport test) and anthropometric indices were measured using standard methods before and after trainings. After determination of data normality using Shapiro–Wilk test, paired samples T-test was used to analysis of data.
Findings: Results showed that HIT trainings were effective in reduction of weight, BMI, WC, HC, WHR, TC and NC and elevation of cardiorespiratory fitness (P≤0/05).
Conclusion: Eight weeks HIT trainings is effective in weight reduction and improvement of obesity anthropometric indices that is desirable for prevention of chronic diseases and body symmetry.
