Effect of an Exergaming on Postprandial Endothelial Dysfunction Following a High Fat Meal in Individuals with Spinal Cord Injury / 대한스포츠의학회지

ABSTRACT

Endothelial dysfunction induced with a high-fat meal may be attenuated with an exercise in abled bodies individuals. Exergaming may be an exercise type applicable for disabled bodied individuals. We tested the hypothesis that an acute bout of exergaming following a high-fat meal would decrease postprandial lipemia, and endothelial dysfunction among individuals with spinal cord injury. Forty participants (age, 41±8 years; 24 males) were randomly assigned to either an exergaming group (n=20) or control group with seated rest (n=20) following a high-fat meal. Hemodynamic and blood parameters and flow-mediated vasodilation (FMD) as an index of endothelial function were measured at baseline and 4 hours after a high-fat meal. In half an hour following a high-fat meal, the exergaming group performed 50 minutes of moderate intensity active video games (Nintendo Wii Sports boxing, tennis). Levels of blood triglycerides increased in both group (p<0.05) following high-fat meal. FMD significantly decreased in the control group (10.4%±4.9% to 7.9%±4.4%) but significantly increased in the exergaming group (10.9%±5.3% to 12.3%±5.3%), with a significant interaction (p=0.004). These results show that a high-fat meal causes endothelial dysfunction in persons with spinal cord injury, but endothelial dysfunction following a high-fat meal was attenuated by an acute bout of exergaming regardless of postprandial lipemia. Therefore, exergaming for individuals with spinal cord injury may have a cardioprotective effect from postprandial endothelial dysfunction induced with an exposure of a high-fat meal.
