Effect of Continuous Exercise Versus Interval Exercise Programs on Selected Parameters of
Metabolic Syndrome,MOHAMAD A. AL-MAGHRABY
Abstract
Background and Purpose: Metabolic syndrome (MetS) represents a group of markers that predispose to obesity, diabetes, cardiovascular disease and hypertension. Regular exercise program is the first step in treating MetS because it increases glucose metabolism by muscles and helps in weight reduction. The purpose of the present study was to determine the effect of continuous exercise and interval exercise programs on selected parameters of MetS.
Subjects and Methods: 36-male patients (47.77±5.9 years) had MetS were participated in the study. Following baseline measurements, patients were categorized into three groups; continuous exercise, interval exercise and control. Patients of both exercise groups performed walking exercise program using the electronic treadmill 3 times per week for 16 weeks supervised by the physical therapist. Data of pre- and post-measures were collected and statistically analyzed.
Results: On comparing the mean post-intervention mea-sured parameters among the continuous exercise, interval exercise and control groups, the results showed a significant reduction in mean waist circumference (107.5±8.6 Vs. 103.2±8.2cm, 106.8±7.6 Vs. 101.5±7.2cm and 107.2±8.2 Vs. 106.9±8.6cm) respectively. There were also significant reduc-tion of mean fasting blood glucose level (118.5±9.5 Vs. 111.8±9.1mg/dl, 116.7±8.8 Vs. 110.8±8.6mg/dl and 116.9±9.3 Vs. 114.9±8.9mg/dl), decrease of mean serum triglycerides (195.2±10.1 Vs. 181.5±9.7mg/dl, 192.8±9.2 Vs. 176.7± 9.7mg/dl and 194.7±10.8 Vs. 192.5±10.6mg/dl) and it was found a significant increase in mean high-density lipoprotein (28.4±7.2 Vs. 37.1±7.6mg/dl, 26.6±6.5 Vs. 41.3±6.8mg/dl and 27.8±7.5 Vs. 28.3±7.8mg/dl) for post-measures of con-tinuous exercise, interval exercise and control groups respec-tively.
Conclusions: Lifestyle modification considered a corner-stone in the management of MetS. Exercise program has been shown to reduce individual components of MetS including; elevated blood pressure, raised plasma triglycerides, elevated blood glucose level and low HDL. Interval exercise program was more effective in improving MetS parameters than con-tinuous exercise program.
