How to prevent stress fractures? 

 Warming up and stretching should always be done before playing. Taking breaks and resting during training sessions will help prevent excessive strain. Another way to prevent stress fractures is to engage in alternative low-impact activities such as swimming or cycling.

In conclusion, tennis, being a popular sport, is prone to injuries in both the upper and lower extremities. Upper body injuries tend to be chronic, while acute injuries are more common in the lower body. Factors such as court surface characteristics, vibration effects caused by racket properties, grip position, pre and post-training warm-up and cool-down routines, and proper placement of the overhead serving style, especially during the initial period, are effective measures in preventing injuries.
