AI for Health Assessment: Revolutionizing Youth Fitness
This research focuses on applying machine learning and deep learning methods to deeply analyze and mine data information, providing automatic classification methods and accurate performance prediction models. This framework extends to offering personalized training suggestions and assisting teachers in making reasonable teaching plans.
It directly addresses the challenges in traditional physical examination management, such as subjective influence, complicated manual calculation, and difficulty in retaining and making full use of data. The core algorithms employed are the BP neural network for automatic comprehensive grade classification and the CNN-LSTM neural network for performance prediction.
Educational Technology: Enhancing Physical Education
A primary application of this AI model is to assist teachers in making more reasonable teaching plans and to optimize the healthy development of students and physical education. By providing data-driven insights, it enables more effective curriculum design.
The system is designed to deliver personalized training suggestions, which cultivates students' awareness of physical exercise from primary schools. The integration of AI tools assists educators in crafting physical education programs that are adaptive, precise, and responsive to individual student needs, moving beyond one-size-fits-all approaches.
Predictive Analytics: Forecasting Fitness Outcomes
The study introduces a performance prediction model based on CNN-LSTM neural network. This advanced model combines CNN feature matrices and LSTM continuous time series information to deliver highly accurate performance predictions for various physical test items.
By leveraging the temporal characteristics of data over recent five years, the CNN-LSTM model is specifically designed for long-term learning and forecasting. This capability is crucial for overcoming the limitations of traditional methods that are deficient in leveraging data for accurate forecasting and strategic planning in physical fitness.
Data Mining: Unlocking Insights from Fitness Data
The foundation of this study is the comprehensive analysis of physical fitness test data from primary schools collected over five years (2018-2022). This extensive dataset includes students' basic information and detailed project-specific measurement results.
Crucial to the model's success is rigorous data preprocessing, including handling missing values, identifying abnormal values, and normalization to ensure data consistency and comparability. Furthermore, principal component analysis is utilized for feature extraction to convert original data into more representative input, thereby effectively avoiding issues caused by the coupling of features and ensuring model robustness.

Tailored PE Interventions & Strategic Planning
The predictive capabilities of the CNN-LSTM model can directly inform personalized pedagogical interventions. By analyzing predicted performance trajectories, teachers can identify students at risk of declining physical capacity or uneven fitness development. For example, if the model predicts a gradual decline in endurance, educators can adjust cardiovascular exercises. Similarly, predicted weaknesses in muscular strength, flexibility, or coordination can guide targeted exercises. This data-driven tool helps teachers make informed, personalized decisions, ensuring adaptive, precise, and responsive physical education interventions.
Impact: Enabled teachers to create data-driven, personalized training plans, leading to more adaptive and effective physical education programs.
