"Strength training" is synonymous with "resistance training," and the two terms can be used interchangeably. Strength training uses the principle of progressive overload to force the body (muscles, bones, tendons, etc.) to adapt in order to be able to produce and resist greater forces. Strength training is not power lifting, nor is it bodybuilding. Also, one does not need to lift weights to strength train. Many exercises can be performed simply using a player's body weight as resistance.
What are the goals/ benefits of strength training?
Strength training for tennis can help to prevent injury and enhance on-court performance. It is important for all tennis players, even young players, to strengthen the muscles of the rotator cuff to maintain a proper strength balance in the shoulder. With young players, the goal of strength training should also be to increase muscular endurance. The goals of strength training should not shift to increasing maximal strength until after a player goes through puberty.
Is strength training safe for young players?
The risk of injury is probably the primary concern of any coach or parent who has a child entering a strength training program. Any exercise or activity carries with it some level of injury risk--even a child running in the backyard can suffer an injury--so it is unrealistic to assume that injuries will never occur in conjunction with strength training. Both the National Strength and Conditioning Association and the American Academy of Pediatrics state that youth strength training can be safe and effective if:
* A competent coach who is skilled in program design supervises every training session
* Proper technique is taught and required in every repetition of every exercise.
Isn't there a risk that growth plates will be damaged?
Many parents and coaches are hesitant to begin strength training with young athletes for fear of damaging the bones and possibly stunting growth. The fact is that no growth plate fractures have been documented in athletes who engage in a resistance training program that follows the two guidelines listed above. The risk of injury to the growth plates can be further minimized if players do not lift heavy weight over their heads or attempt to lift extremely heavy weights. Growth plate injuries should be taken seriously because they can happen. However, with proper care the risk can be almost eliminated.
Does strength training work for young players?
Yes, it does. Most people believe that testosterone (a steroid produced naturally in the body) is necessary to build strength. However, resistance training helps to improve motor control and strength by "teaching" muscles how to work together in a coordinated manner, which leads to improvements in strength without an associated gain in muscle mass. Some other benefits of youth strength training are:
* Improved strength and coordination
* Increased bone density
* Improved self-image and self-confidence
* Potential to prevent injuries
