Abstract:
Background: Obesity is linked to impairments in motor control, cardiovascular fitness, and respiratory function. Dynamic Neuromuscular Stabilization (DNS) aims to enhance core stability, diaphragmatic breathing, and neuromuscular coordination. This study investigated the effects of a 6-week DNS program on these functional outcomes in overweight and obese women. Methods: Thirty-six participants (aged 35-50 years, BMI: 25-34 kg/m2) were randomly assigned to either an experimental group (n = 18), which underwent DNS training, or a control group (n = 18), which received no intervention. The DNS program consisted of six weekly sessions (three supervised, three home-based), emphasizing core stabilization, diaphragmatic breathing, and neuromuscular coordination. Motor control (lumbar movement control tests), cardiovascular fitness (two-minute step test), and respiratory performance (breath-hold time, respiratory rate, and respiratory muscle strength) were assessed before and after the intervention. Results: The DNS group demonstrated significant improvements compared to the control group, with notable increases in motor control scores (p < .001) and cardiovascular fitness (p < .001). Additionally, inspiratory and expiratory breath-hold times (p < .001 for both), respiratory rate (p < .001), and maximum inspiratory and expiratory pressures (p < .001) showed substantial enhancements. No significant changes were observed in the control group. Conclusion: A 6-week DNS exercise program significantly improved motor control, cardiovascular fitness, and respiratory performance in overweight and obese women. These findings support DNS training as an effective intervention for enhancing core stability, breathing efficiency, and neuromuscular coordination, with potential applications in rehabilitation and health promotion.

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
01:20Exercise 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...

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...
