Brief 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.
Eligibility Criteria
Inclusion Criteria: * Healthy adults aged 18-35 years * Recreational to competitive non-professional tennis players (currently playing ≥2 sessions/week for ≥1 year; NTRP 3.0-5.0 or equivalent ITN; no professional ranking or tour-level competition history) * Right- or left-hand dominant (serve arm recorded) * Able to perform a full flat serve without pain * Willing to maintain current tennis training routine and refrain from starting other new strength/conditioning programs during the study Exclusion Criteria: * Current or history of shoulder pain/injury in the past 6 months (e.g., rotator cuff pathology, labral injury, impingement) * Low back pain or lumbar spine pathology in the past 6 months * Prior shoulder or spine surgery * Systemic conditions affecting neuromuscular function (e.g., uncontrolled diabetes, neurological disorders) * Pregnancy * Current participation in a structured core or shoulder strengthening program
