Abstract

Diabetes has become a fundamental health concern in Westernized society due to its high morbidity and mortality rates. Therefore, it is imperative that the onset of diabetes be prevented via serum glucose levels maintenance prior to further complications arising. A randomized, comparative, research trial was instituted in an attempt to evaluate the most effective exercise modality as a preventative intervention in the development of Type II Diabetes. Sedentary, non-diabetic male adult subjects were matched and randomly assigned into either a 16-week non-exercising control group (ConG), aerobic exercise group (AerG) or resistance and aerobic exercise group (RaG). Dependent t-tests on 50 subjects (ConG: n = 12, AerG: n = 12; RaG: n = 13) revealed that the fasting serum glucose levels of the ConG did not significantly change (p = 0.289), while both the AerG and RaG significantly decreased their mean serum glucose levels (p = 0.002 and p = 0.004, respectively). The Mann-Whitney Test demonstrated that AerG and RaG were equally effective at decreasing serum glucose levels (p = 0.538; p 0.05). Spearman's correlation coefficient indicated no significant correlations between serum glucose levels and alterations in smoking behaviour (r = 0.084), body mass (r = - 0.080), waist-to-hip ratio (WHR) (r = 0.088), the dietary intake of fat (r = - 0.031), saturated fat (r = 0.091), fibre (r = 0.256) and carbohydrates (r = 0.066). However, a significant moderate correlation was found between serum glucose levels and percentage body fat (r = 0.474). These findings demonstrated that aerobic exercise and the combination of resistance and aerobic exercise can both mitigate postpranial decreases in serum glucose levels while the case for the addition of resistance training to conventional aerobic exercise in the form of combination exercise training in the preventative intervention in the development of Type II Diabetes is strengthened.
