Front- and back-hand shots require a large amount of trunk rotation and twisting in the spine when playing tennis
The tennis serve hyper-extends the lower back and can compress lumbar discs
Back muscles must support continual sudden forward and lateral movements and start-and-stop motions during a game of tennis
Learn about the different racket tensions and be fitted by a professional for the proper tennis equipment; a more flexible tennis racquet requires more trunk rotation than a stiffer tennis racquet with looser strings
Consider using a slice serve rather than a kick serve to reduce the degree of back arch when playing tennis
Use proper form during tennis, bending the knees, holding in the abdominal muscles
Have a tennis professional check your form periodically
For new players, professional tennis instructors can teach you proper form and make suggestions on how to avoid back injuries, back pain or stress on the back
