The comparision of three different type of exercise training on body composition, insulin resistance and lipid profile biomarkes in elderly Women

Introduction: Aging and obesity associated with it, is a key factor in the etiology and progression of some chronic diseases. However, the majority of published data suggests that regular exercise training improves the health markers in older people and has considerable efficacy counteracting the aging process and associated diseases. Therefore, the present study conducted to compare the effect of three different type of exercise training training on the insulin resistance and lipid profile indices in obesity elderly Women. Methods: Forty eight obese elderly women with BMI ≥30 voluntarily selected with convenience sampling method and were assigned into four groups of control (n=12, age: 62.24±4.84), aerobic (n=12, age: 60.51±4.62), resistance (n=12, age: 58.91±3.83) and concurrent exercise training (n=12, age: 60.77±5.05) for eight weeks. At baseline and after eight weeks, body compoeition indices and venous blood samples were evaluated from all subjects. Data were analyzed by paired t-test and one-way analysis of variance tests and performed by SPSS software version 24 at significance level p<0.05. Results: The results indicated that all three exercise training methods significantly improved the indicators of body composition (weight, body fat percent and waist circumference), lipid profile (total colestrol, TG, LDL-C, HDL-C) and insulin resistance (HOMA-IR) in elderly obese women (p<0.05) after eight week training. In addition, comparison of training methods showed that there was a significant difference between the combined group with the other two training methods in weight and body fat percentage and between the combined group and the resistance group in the BMI index, which indicated a further decrease in these indicators in this training method (p<0.05). However, the comparison of other markers between training groups was not significant (p>0.05). Conclusions: According to results from this study it can be concluded that independent of abundant timprovement in weight and body fat percentage in the combined exercise group, all three methods of exercise training can improve and reduce the risk factors of chronic diseases in obese elderly women.
