The study relies heavily on self-reported data from questionnaires, which can be subject to biases and inaccuracies. Participants may overestimate or underestimate their exercise frequency or mental health status.
The study is conducted at a single university in China, limiting the generalizability of the findings to other populations and cultural contexts. The results may not be applicable to college students in other countries or even other regions within China.
Correlation does not equal causation
While the study finds a correlation between increased exercise and improved mental health, it does not establish causality. Other factors, such as social support, diet, or access to mental health services, could also contribute to mental well-being.
Simple recommendation algorithm
The study uses a relatively simple recommendation algorithm based on age, BMI, and health status, which may not be personalized enough to meet the diverse needs of individual students. More sophisticated algorithms incorporating factors such as fitness level, preferences, and goals could lead to better outcomes.
Limited evaluation of system effectiveness
The evaluation of the intelligent sports system is limited to a functional test of the booking system and user satisfaction surveys. More rigorous evaluation methods, such as randomized controlled trials, are needed to determine the effectiveness of the system in improving sports participation and mental health.
