Summary

This summary is machine-generated.

Indoor air quality in Chinese sports buildings is generally good at rest but declines during exercise. Increased carbon dioxide and PM2.5 levels negatively impact athlete health, highlighting the need for better ventilation strategies.

Background:

Indoor air quality (IAQ) significantly impacts human health, especially in sports facilities.
Hot summer and cold winter climate zones in China present unique IAQ challenges.
Badminton courts are typical indoor sports venues where IAQ is crucial for athlete well-being.

Purpose of the Study:

To assess the current IAQ status in typical indoor badminton courts in China's hot summer and cold winter climate zones.
To evaluate IAQ parameters during different seasons and predict them for non-testing periods.
To understand the impact of natural ventilation and exercise on IAQ.

Main Methods:

Field testing of indoor environmental parameters (CO2, PM2.5) in 10 Hubei Province cities during spring and autumn.

Analysis of IAQ data under natural ventilation conditions.

Correlation analysis between exercise duration and IAQ parameters.

Main Results:

Average daily indoor CO2 concentrations were 526.78 ppm (spring) and 527.63 ppm (autumn).
Average daily PM2.5 concentrations were 0.035 mg/m³ (spring) and 0.024 mg/m³ (autumn).
All tested parameters met GB/T 18883-2022 standards at rest, but CO2 and PM2.5 levels increased with exercise duration, degrading IAQ.

Conclusions:

While resting IAQ in these badminton halls meets standards, exercise significantly elevates CO2 and PM2.5.
The declining IAQ during exercise poses potential health risks to athletes.
Optimized ventilation strategies are needed to maintain healthy IAQ during sports activities.
