Objective:
Recently, exergames have been used an exercise modality as aerobic fitness activities. However, evidence of its effectiveness on cardiovascular (CV)-related risk factors remain unclear.
Hypothesis:
We evaluate the effects of exergaming on CV-related risk factors compared with traditional aerobic exercise in high CV risk patients.
Methods:
Sixty-five postmenopausal women with high CV risk were randomized among exergame (n = 22), treadmill (n = 22), and control (n = 21) groups. The exergame group was engaged in the running-based exergame using Exer Heart and the treadmill group walked or jogged on a treadmill. Cardiorespiratory fitness, flow-mediated dilation, endothelial progenitor cells (EPCs), epicardial fat thickness, metabolic parameters, and anthropometric parameters were measured in patients before and 12 weeks after the training.
Results:
Exergaming significantly improved VO2 peak (P < .001; different from control, P < .05), flow-mediated dilation (P < .001; different from control, P < .05), EPCs (CD34/CD117+ , P < .01). Treadmill exercise was effective at improving VO2 peak (P < .01; different from control, P < .05), flow-mediated dilation (P < .05), EPCs (CD34/CD117+ , P < .01; different from control P < .05). Epicardial fat thickness decreased after both exercise programs (exergame, P < .01; treadmill, P < .01; no different from control).
Conclusion:
Exergaming showed similar effects to traditional aerobic exercise in improving cardiorespiratory fitness and endothelial function in postmenopausal women with high CV risk. These findings suggest that the exergames may serve as an alternative to conventional aerobic exercises for prevention and treatment in high CV risk patients.

01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

01:26Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
