Purpose:
The study determined whether an exergame training (EXT) resulted in greater improvements in health-related outcomes compared to traditional moderate-intensity continuous training (MICT).
Methods:
In total, 47 individuals (age 30±11 years) were randomized into an EXT (n = 24) and an MICT group (n = 23). Throughout the eight-week intervention period, the EXT group attended 20-30 min of EXT three times a week while the MICT group completed 20-45 min of MICT three times a week. Before and after the intervention, BMI, waist-to-height ratio, body fat (BF), resting heart rate (HR), root mean square of successive differences between normal heartbeats (RMSSD), standard deviation of all normal-to-normal intervals (SDNN), average time interval between consecutive R-waves (MeanRR), high-frequency power, low-frequency power, ratio of LF to HF power, enjoyment, systolic (SBP) as well as diastolic blood pressure, and peak oxygen consumption (VO2peak) were compared using linear mixed models.
Results:
The analyses revealed main effects of time for BF, HR, RMSSD, SDNN, MeanRR, high-frequency power, and SBP (ps<.05). A main effect of group was found for enjoyment (p<.05) with higher values in the EXT group. Group-by-time interactions (ps<.05) were observed for HR, SBP, and VO2peak, indicating differential changes over time between groups. The EXT showed a steeper decline in HR and SBP compared to MICT, while demonstrating a greater increase in VO2peak.
Conclusions:
The EXT was more effective than the MICT in improving VO2peak, HR, and SBP. The EXT seems to represent a more effective and more attractive alternative to MICT for health promotion.

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.
Purposes
01:27Exercise and Muscle Performance
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
