Abstract
Background: Globally, nearly 300 million adults are recognized as obese, a condition intricately linked to the prevalence of metabolic syndrome (MetS). MetS can lead to cardiovascular disease and metabolic bone disorders. Exercise training is reported as a treatment to mitigate risk factors associated with MetS.
Objective: This study aimed to compare the effect of aerobic interval training (AIT) and resistance training (RT) on glycemic control and cardiovascular markers in men diagnosed with MetS.
Materials and Methods: Thirty-one male subjects (age: 45.8 ± 4.9 years) with MetS were recruited through advertisements after obtaining approval from the Ethics Committee of the Ferdowsi University of Mashhad, Iran. Participants were randomly assigned to AIT (n=10), RT (n=10) or a control group (CON, n=11). AIT involved 4 × 4 min intervals of walking/running on a treadmill, and RT included seven exercises using weight machine. Both interventions were conducted three times a week over a 12-week period. The CON group did not engage in any physical activity during this period. Blood samples were collected before and after the intervention.
Results: A significant group by time interaction was observed for all variables, excluding systolic and diastolic blood pressure (all p < 0.001). Preptin, glucose, HbA1c, low-density lipoprotein, triglyceride, total cholesterol, and body mass index significantly decreased in the AIT group compared to the CON and RT groups. Insulin resistance significantly decreased in both exercise groups compared to the CON group. Additionally, body mass decreased significantly in the AIT group compared with the CON group, while fat% and waist circumference significantly decreased in the RT group compared with the CON group. Maximal oxygen uptake (VO2max) and high-density lipoprotein significantly increased in the AIT group compared to the RT and CON groups. Lean body mass increased significantly in the RT group compared to the CON group.
Discussion: Exercise training, particularly AIT and RT, emerges as an effective non-pharmacological intervention for managing glycemic control and improving cardiovascular health in individuals diagnosed with MetS.
