The invention relates to the technical field of tennis training, in particular to a tennis
core strength training model establishing method, which comprises the following steps of: inducing to generate
muscle activation stimulation in a core
muscle group through tennis training actions, and acquiring a total training stimulation amount based on a process that the
muscle activation stimulation is captured by a muscle
fiber and a nerve-muscle joint movement unit; determining a
core strength increase equation based on the total training stimulation amount, and integrating the individual characteristic parameters of the
athletes to construct a scalable
core strength increase model; a scalable fatigue
recovery model based on a BP neural network is obtained and used for quantifying the dynamic relation between the fatigue index and the athlete individual characteristics, training parameters and
recovery time, and training cycle planning is optimized; a core strength increasing model and a fatigue
recovery model are fused, a core
strength training effect scalable model is formed, the change relation between the
training effect and athlete individual characteristics, training parameters and training stages is comprehensively measured, and scientific and personalized core
strength training scheme design and dynamic adjustment are achieved.
