The following points can be done to prevent or minimize overuse injuries ...

• Avoid overuse. As discussed above, use common sense, and tailor a training program suitable for that child, taking into consideration his maturity and athletic ability.
  
  

• Proper nutrition. Make sure child has enough nutrition for growth and sports.

• Pre-sports physical. Any anatomic malignment should be corrected. For example, shoe inserts for pes valgus and genu valgum. Any tight muscles or tendons, or muscle imbalance should be corrected by stretching and strengthening exercises.
  
  For example, hamstring and heel cord tightness should be corrected by stretching. Muscle imbalance between the vastus lateralis and medialis (VMO) should be corrected to prevent patello-femoral pain. Any systemic or other general health problems should be addressed before the child participates in competitive sports.
  
  

• Proper warmup and stretching exercises specific to the sports before playing. Proper warmup could consist of 5 minutes of jogging till one gets a slight sweat. Then 5 minutes of stretching exercises would prepare the child for competition.
  
  

• Proper equipment. The runner should have shoes that have a firm and padded heel cushion, flexible sole for bending at the forefoot when running, and adequate cushioning.
  
  He should also train on soft running surfaces rather than concrete or asphalt. The young tennis player should be fitted for a racket that allows him to get a good grip on the handle.
