INTRODUCTION:
The Weather conditions are an important factor affecting outdoor sports. The running was the most popular sport in 2023, with an estimated 620 million participants, representing 7.8% of the global population; compared to indoor running, outdoor road running is the preferred choice for runners, offering better training benefits and adaptation. As outdoor running self-exercise gradually become an essential element of personal health management, understanding how environmental factors influence individual exercise performance helps participants to improve training outcomes and provides scientific evidence to reduce potential risks. The Purpose of this study was explored the relationship between weather factors and outdoor running self-exercise performance. The Weather factors were treated as control variables and the exercise performance as criterion variables to understand further how complex and variable weather conditions affect outdoor exercise performance.
METHODS:
The Data were collected from 33 participants and 824 outdoor running records, with relevant weather data retrieved and integrated from public datasets on the day of exercise. The data included wearable device outputs (e.g., heart rate, speed, distance, pace) and meteorological information (e.g., temperature, humidity, wind speed, and precipitation). The Canonical Correlation Analysis was applied to examine the relationships between various on weather factors and exercise performance.
RESULTS:
The influence coefficient of the day's lowest temperature (-0.62) is a significant factor affecting exercise parameters on Outdoor Running Self-Exercise. Lower temperatures contribute to better performance, so it is recommended that outdoor runners choose to exercise during cooler times of day, such as early morning or late afternoon. The influence coefficient of weather conditions on "running distance" is 0.55. Suitable low temperatures and moderate wind speeds can extend the runner's activity time, thereby increasing the running distance. The influence coefficient of weather conditions on "calories" is 1.03, indicating that exercise efficiency is higher and calorie consumption is relatively increased under conditions of lower temperatures and moderate humidity.
CONCLUSION:
The Weather conditions have a significant effect on outdoor running self-exercise performance. Suitable weather conditions can enhance exercise efficiency, and the "lowest temperature" has a significant effect on improving performance. The results are valuable for exerciser, trainer, and health managers. It is recommended that future research should explore individual differences and personalized adaptation strategies to provide precise recommendations for exercise participants.
