| ABSTRACT |
|
A high fat meal transiently decreases vascular function, while acute aerobic exercise improves vascular function. Active video games are now highly popular and play a role in promoting physical activity. Although studies suggest that acute aerobic exercise attenuates high fat meal induced vascular dysfunction, but it is not clear whether an active video game could attenuate vascular dysfunction after a high fat meal. We tested the hypothesis that an active video game would partially prevent the unfavorable effect of vascular function by high fat meal in young adults. Using a randomized cross over design, sixteen healthy young subjects (male 9, female 7；age 24±4 yrs, BMI 22.4±2.1 ㎏/㎡) were assigned to both an active video game(AVG：50 minutes) and a seated rest(CON) after a high fat meal. Lipid profiles, blood pressure, and vascular function measured at baseline, 3 and 5 hours after a high fat meal. Vascular function was measured by endothelial function(brachial artery flow mediated dilation；FMD) and arterial stiffness(carotid-femoral pulse wave velocity；C-F PWV). Blood triglyceride levels were significantly increased in two treatment conditions after a high fat meal and did not significantly different between two groups(AVG：74.06±43.36, 160.63±106.20, 126.81±91.41 mg/dl；CON：70.06±38.67, 168.38±85.89, 128.75±87.26 mg/dl, p=0.878). FMD was decreased in the CON (9.32±2.86 to 8.13±3.56 %), but increased in the AVG (8.74±3.13 % to 9.21±3.40 %) at 3 hr after a high fat meal. However, there was no significantly different between two groups (p=0.189). C-F PWV was similarly decreased in two treatment conditions after a high fat meal and did not significantly different between two groups (AVG：6.39±1.12, 6.08±0.94, 6.38±1.07 m/s；CON：6.34±0.85, 6.19±0.89, 6.28±1.01 m/s, p=0.483). These findings show that a high fat meal caused a temporary decrease in endothelial function, but these decreases were not significantly attenuated in the group with active video game compare to the group with seated rest. Therefore, active video game may not have a cardioprotective effect in young healthy adults exposed to acute high fat meal. |
