The Addition of Core Muscle Training on Tennis Serve Speed in Tennis Players
Sponsor: Cairo University
Summary
Compared with shoulder-only training and with continued tennis training alone, will the addition of core strengthening to shoulder training produce significantly greater improvements in flat serve ball speed in healthy tennis players? Secondary Hypothesis: * Combined core + shoulder training will produce greater improvement in serve accuracy than shoulder-only training or tennis training alone. * Combined core + shoulder training will produce greater improvement in TGAR than shoulder-only training or tennis training alone. * Combined core + shoulder training will produce greater improvement in core strength/endurance and shoulder rotational strength than the comparator groups.

Interventions
Shoulder Strengthening Program+ Sham core Treatment
Delivered 2×/week for 10 weeks under supervision of a licensed physical therapist or certified strength and conditioning specialist. Progressive resistance program including: * External/internal rotation strengthening (resistance band, cable, or dumbbell) at 0° and 90° abduction * Scapular stabilization exercises (rows, Y-T-W raises, serratus punch) * Posterior shoulder stretching (sleeper stretch, cross-body stretch) for the TGAR component * Progressive overload every 2 weeks based on tolerated resistance/repetitions Sham :Low-intensity, non-progressive trunk mobility exercises with minimal loading (e.g., seated trunk rotations without resistance, cat-camel stretches), matched for session time and attention to control for non-specific training effects, without targeting core strength/endurance adaptation.
Shoulder Strengthening Program+ Core Strengthening Program
Delivered 2×/week for 10 weeks, same sessions as the shoulder program (combined \~50-60 minute sessions), progressive core program including: * Anti-rotation exercises (Pallof press) * Rotational power exercises (medicine ball rotational throws, cable woodchoppers) * Anterior/lateral/posterior chain stability (plank variations, side plank, bird-dog) * Progressive overload via increased resistance, hold time, or instability surface every 2 weeks
