To compare the mitigating effects of different interventions-low-concentration oxygen-enriched air and exercise-on mental fatigue. Researchers recruited 25 healthy male subjects and had them perform a Stroop task to induce cerebral fatigue, then different interventions (meditation, placebo, low-concentration oxygen-enriched air, exercise, and low-concentration oxygen-enriched air plus exercise) were used to provide recovery interventions to subjects, and recovery from cerebral fatigue was assessed by measuring psychometric scales, galvanic skin activity, heart rate variability, and cognitive executive tasks. The results showed that low-concentration oxygen-enriched air and exercise were effective in relieving cerebral fatigue and improving cognitive executive function, and the combined intervention was particularly effective, showing the most comprehensive benefits.

Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...

Exercise 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.
