What this trial studies

This randomized controlled trial aims to evaluate the impact of a 4-week core strengthening program versus a shoulder strengthening program on the flat serve velocity of amateur young adult tennis players. Participants will be divided into two groups, with each group undergoing a different training regimen. The study will assess serve velocity before and after the intervention by having participants serve the tennis ball multiple times. The goal is to determine which strengthening program is more effective in enhancing serve speed.

Why it matters

Potential benefit: If successful, this study could help improve serve velocity in young adult tennis players, enhancing their performance on the court.

How similar studies have gone: While there have been studies on strength training in athletes, this specific comparison of core versus shoulder strengthening in tennis serve velocity is relatively novel.
