Experiment content.

Classification	Projects	Exercise content	Exercise time	Movement frequency	Duration of ciliary muscle intervention
Open Motor skills	Basketball	High dribbling, low dribbling, two-handed chest pass, two-handed chest shot, passing and cutting tactics, etc.	Total 4 weeks 40 min each time	Three times a week	Control group without ciliary muscle intervention and normal participation in physical education classes. The hourly value of the ciliary muscle intervention in the experimental group was 3 s/visit, and the distance-approach vision was 30 frequencies; since the ciliary muscle intervention is an exercise, it cannot be estimated accurately and depends on the content of the exercise.
	Soccer	Dribbling on the inside of the back of the foot, dribbling on the front of the back of the foot, passing and receiving on the inside of the foot, kicking on the inside of the foot, passing and cutting tactics, etc.	Total 4 weeks 40 min each time	Three times a week
