Objective:
To evaluate the suitability of the Wii Fit Plus exergame as a tool to improve cardiorespiratory fitness in individuals with type 2 diabetes.
Design:
Experimental cross-sectional study.
Setting:
Controlled laboratory.
Participants:
Twelve type 2 diabetic patients (10 male and 2 female; age, 60.2 ± 7.7 years; body mass index, 30.9 ± 6.2 kg/m).
Interventions:
At baseline, all participants underwent an all-out cardiopulmonary exercise test on a treadmill to assess peak and average oxygen consumption (V[Combining Dot Above]O2peak and V[Combining Dot Above]O2mean). Forty-eight to 72 hours after the cardiopulmonary exercise test, the same parameters were assessed during three 10-minute bouts of Wii Fit Plus exergaming and converted to percentage of treadmill V[Combining Dot Above]O2peak (%V[Combining Dot Above]O2peak).
Main Outcome Measures:
V[Combining Dot Above]O2peak and V[Combining Dot Above]O2mean during Wii Fit Plus play relative to V[Combining Dot Above]O2peak achieved during the cardiopulmonary exercise test.
Results:
All Wii Fit Plus exercises generated a V[Combining Dot Above]O2peak of around 60% and V[Combining Dot Above]O2mean of around 40% of the V[Combining Dot Above]O2peak as established during the cardiopulmonary exercise test. Mean heart rate and resting energy expenditure (respiratory exchange ratio) lay in a range of moderate aerobic exercise. A moderate-to-strong correlation between treadmill V[Combining Dot Above]O2peak and both exergame V[Combining Dot Above]O2peak and exergame V[Combining Dot Above]O2mean was found.
Conclusions:
Video gaming has the potential to offer training intensities that concur with established guidelines for type 2 diabetic patients. The training intensity is self-adjusting based on fitness level allowing for an effective workout for different users.

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.
