Influence of a mini trampoline rebound exercise program on insulin resistance, lipid profile and central obesity in individuals with type 2 diabetes.

BACKGROUND

Exercises are important as an adjuvant for managing diabetes but due to fatigue and time constraints, individuals with diabetes may not engage in them. Jumping on a mini-trampoline referred to as rebound exercise is an aerobic activity used for exercise training benefits but only little research is available on its effects in diabetes. The purpose of this study was to determine the effect of mini-trampoline rebound exercise on insulin resistance, lipid profile and central obesity in type 2 diabetics.

METHODS

Sixty non-insulin dependent type 2 diabetics (median age: 39.0 years, median body mass index: 25.2 kg/m2) recruited using convenience sampling were randomized to a rebound exercise group (N.=30) or a control group (N.=30). The control group read health magazines or watched television while the rebound exercise group jumped on a mini-trampoline at moderate intensity for 30 minutes three times per week for 12 weeks.

RESULTS

Postrebound exercise, significant improvements in insulin resistance, lipid profile and waist circumference were noted when compared to the control (P<0.05). The values for high density lipoprotein cholesterol increased with low density lipoprotein cholesterol, triglycerides, insulin resistance decreasing significantly from baseline (P<0.05).

CONCLUSIONS

The findings suggest that mini-trampoline rebound exercise is beneficial for individuals with type 2 diabetes and can serve as a useful exercise approach in the management of cardiovascular risk in diabetes.
