Effect of Upper-limb Plyometric Training Versus Strength Training for Enhancing Serve Velocity, Strength, and Power in Competitive Tennis Players

Tennis performance is highly dependent on the ability to generate force, speed, and coordination, particularly during the serve. Upper-limb strength and power play a crucial role in producing high serve velocity, which is a key determinant of competitive success. Various training approaches have been used to enhance these physical attributes, including traditional resistance training and plyometric training. Plyometric training focuses on explosive movements that utilize the stretch-shortening cycle, potentially improving neuromuscular efficiency and power output. In contrast, traditional strength training emphasizes muscle force production through controlled resistance exercises. While both approaches are widely used, there is limited comparative evidence regarding their effectiveness in improving tennis-specific performance, particularly serve velocity. This randomized controlled trial aims to compare the effects of upper-limb plyometric training and strength training on serve velocity, muscular strength, and power in competitive tennis players. Participants will be randomly allocated into two groups: a plyometric training group and a strength training group. Each group will follow a structured training program for a specified duration under supervised conditions. Outcome measures will include serve velocity (measured using a radar gun or equivalent device), upper-limb muscular strength (assessed through standardized strength tests), and power (evaluated using validated performance tests). Assessments will be conducted at baseline and after completion of the intervention.
