Abstract

Obesity has reached epidemic proportion in both developed and developing countries in the world. Physical inactivity is a contributing factor for obesity epidemic. Studies have done to investigate the independent effect of aerobic and resistance exercise training on obesity. However, there are no sufficient evidences to explain the combined effect of aerobic and resistance exercise in a workout on obesity. The aim was to assess the effect of combined aerobic and resistance exercise training (CART) on weight control and body composition, blood and metabolic variables, muscle strength and cardio respiratory fitness in obese adults. We examined the 12 weeks combined aerobic and resistance exercise training on 30 obese Ethiopian adults (mean age 45.2±5.4). Baseline and after12 weeks training test included anthropometric, Body composition, fasting blood glucose and total cholesterol, blood pressure, VO2max and muscular strength (1RM) were done by using standard techniques. Incremental treadmill running test protocol and 1 RM were employed for VO2max and strength test. Data was analyzed by using SPSS statistical package software (version 16.0 for window). Paired sample T test was employed for pre and post test difference assessment. After 12 weeks training significant (p<0.001) reduction was observed on body weight (6.1%), BMI (6.3%), body fat percentage (11.6%),Visceral fat(10.8%), systolic BP (1.97%), blood pressure, Fasting blood glucose (5.9%) and total cholesterol (4.3%). The intervention brought significant (p<0.001) greater change on Skeletal muscle percentage (10.4%), VO2max (71.5%) and on 1RM (26.3 %,) from baseline. In conclusion, intervening CART in every training session brought significant improvement on weight loss and body fat control, Fasting Blood Glucose and Total cholesterol. Moreover, significant parallel improvement on cardio-respiratory and muscular strength fitness was resulted due to combined exercises intervention. Combining the two types of exercises in a session gives a chance the participants to enhance their aerobic and strength fitness simultaneously.
