The invention discloses a personalized
exercise prescription generation method fusing
deep learning, learnable similarity and multi-
modal time sequence analysis. The method comprises the steps that firstly, static signs and
health risk labels of a user and dynamic signals such as the
heart rate, the HRV and the
step number collected by wearable equipment in real time are integrated, and unified modeling is conducted through a multi-
modal encoder to form individual state vectors; then outputting a preliminary motion scheme by a BERT-Transform
text generation model, mapping a user to a hidden space taking a historical execution effect as supervision by using a comparative
learning network, and accurately inferring an FITT core parameter through approximate nearest neighbor retrieval and effect weighting; performing consistency optimization on texts and parameters through a large
language model, completing risk
verification under a
safety barrier constructed by a medical rule base, ensuring that output meets clinical taboo and individual tolerance, and finally continuously optimizing long-term health income under medical constraints in combination with an offline
reinforcement learning strategy, and cooperating with meta-learning
cold start and
uncertainty estimation, so as to achieve the purpose of improving the safety of the
health management system. Safe, accurate, self-adaptive and explainable personalized
exercise prescription generation for new and old users is realized, and the method can be widely applied to intelligent fitness,
chronic disease exercise intervention and digital health management scenes.
