Effect of Core Versus Shoulder Strengthening on Tennis Serve Velocity in Young Adult Tennis Players

The goal of this randomized controlled trial is to evaluate the effect of a 4-week core strengthening program on flat serve velocity and arc of shoulder rotation in amateur young adult tennis players . Participants will serve the tennis ball four times during the initial and final flat tennis serve assessments. Furthermore, participants will be divided into two groups and given different strengthening programs. Researchers will compare Group A (shoulder strengthening group) and Group B (core strengthening group) to see if there is any difference between the core and shoulder training programs on the flat serve velocity.
