135 terms
- Kinetic Chain BreakdownIntermediateA kinetic chain breakdown is a skipped or broken link in the ground-up leg, hip, torso, and arm sequence. The arm then has to make power on its own.Tennis
- Late Contact (Tennis)IntermediateLate contact means the racquet meets the ball behind the ideal contact point, usually behind the front hip. It costs pace, direction control, and spin.Tennis
- Late Split StepIntermediateA late split step lands after the opponent has struck the ball. The player is still airborne or resettling just when they need to push off toward the shot.Tennis
- Leg Drive on GroundstrokesIntermediateLeg drive is the push off the ground that starts the kinetic chain on a groundstroke. It sends upward and rotational energy into the hips, torso, and arm.Tennis
- Let (Serve Rule)BeginnerA let is called when a serve clips the net cord and still lands in the correct service box. The point is then replayed with no penalty to the server.Tennis
- LobIntermediateA lob is a high, arcing shot meant to clear a net player's reach. On defense it buys time; on offense, a topspin lob near the baseline can win the point.Tennis
- Lob DefenseBeginnerLob defense is using a high, deep shot over an approaching or net-positioned opponent. It buys time, resets the point, or forces a difficult overhead.Tennis
- Long Backswing Timing IssueIntermediateA long backswing timing issue is a backswing that takes longer than the ball allows. The forward swing is rushed or unfinished, however clean it looks.Tennis
- Loop BackswingIntermediateA loop backswing takes the racquet back and up, then drops it down into the forward swing. The circular path builds racquet-head speed and rhythm.Tennis
- Loss of Balance on Stretch ShotsIntermediateLoss of balance on stretch shots is reaching past a stable base for a wide, low, or hard-hit ball. The center of mass falls away from the shot at contact.Tennis
- Match Tiebreak (10-Point)BeginnerA match tiebreak (or "super tiebreak") is a first-to-10-points breaker, won by two clear points. It is played instead of a full third set in many doubles and some singles formats.Tennis
- Mis-Hit CausesBeginnerMis-hits usually trace to four root causes: contact timing, footwork spacing, balance, or grip mismatch. Finding the one that repeats is the fastest fix.Tennis
- Momentum Shift in a MatchAdvancedA momentum shift is a clear change in which player controls a match. Breaks of serve, long games won on key points, and runs of games often trigger it.Tennis
- Moon BallIntermediateA moon ball is a very high, heavily topspun groundstroke. It disrupts rhythm and buys recovery time without going as high or defensive as a lob.Tennis
- Movement PatternIntermediateA movement pattern is the sequence of footwork steps a player uses to reach the ball, execute the shot, and recover to position — combining split step, approach steps, stance, and recovery.Tennis
- Natural Gut StringAdvancedNatural gut is made from cow intestine. It offers the most elasticity, tension retention, and comfort of any string, but costs more and is less durable.Tennis
- Net Approach TimingIntermediateNet approach timing is when a player moves in to the net, relative to their shot and the opponent's reply. The aim is to split step as the opponent hits.Tennis
- Neutral Rally BallBeginnerA neutral rally ball is a moderate-pace, high-margin shot hit deep and crosscourt. It keeps the rally going without risk or giving up the initiative.Tennis
- No-Ad Scoring (Deciding Point)BeginnerNo-ad scoring replaces deuce and advantage with a single deciding point at 40-40. So the next point played wins the game outright.Tennis
- One-Handed BackhandIntermediateA one-handed backhand uses only the dominant hand. It gives more reach and disguise than a two-hander, but less stability against high-bouncing pace.Tennis
- Open StanceIntermediateAn open stance positions both feet roughly parallel to the baseline at contact. This allows the hips to rotate powerfully through the ball without requiring a weight transfer step.Tennis
- Open-Stance ForehandIntermediateAn open-stance forehand is hit with the front foot and hips facing the sideline, not the net. Hip rotation then powers it without a full weight transfer.Tennis
- Overhead / SmashIntermediateThe overhead (or smash) is a serve-like stroke struck above the head to put away a lob, demanding quick shoulder turn, a trophy-position racquet path, and aggressive pronation through contact.Tennis
- Overhead Smash FootworkIntermediateOverhead smash footwork is the adjustment steps and final scissor or step-in move that get a player under a lob. It lets them hit with power and balance.Tennis
- Passing ShotIntermediateA passing shot is hit by the baseline player when the opponent has approached the net, aiming to place the ball past the net player through an angle or pace that cannot be volleyed.Tennis
- Poaching (Doubles)IntermediatePoaching is when the net player in doubles crosses over to intercept a ball meant for their partner. It cuts off the angle and finishes the point at net.Tennis
- Polyester StringIntermediatePolyester is a stiff, durable monofilament string built for spin. But it transmits more shock to the arm compared to natural gut or multifilament strings.Tennis
- Pronation on ServeAdvancedPronation on serve is the forearm's natural inward turn around contact. It squares the face and adds speed, but shoulder internal rotation adds the most.Tennis
- RA / StiffnessProRA is a racquet's stiffness measured by how much the frame deflects under load. Higher RA (66+) means a stiffer, more powerful but harsher frame; lower RA (under 58) flexes more for feel and arm comfort.Tennis
- Racquet DropAdvancedThe racquet drop is the racquet head falling passively below the wrist after the unit turn. From there, a low-to-high swing whips topspin onto the ball.Tennis
- Racquet Face Angle at ContactIntermediateRacquet face angle at contact is the string bed's tilt from vertical when the ball is struck. It mainly decides the ball's launch direction and spin type.Tennis
- Racquet Head SpeedIntermediateRacquet head speed is how fast the racquet head is traveling at contact. It is the single largest factor in ball pace and spin on a given stroke.Tennis
- Rally LengthBeginnerRally length is the number of shots in a point from serve to finish, a tactical metric that reveals whether a player wins most points early (0–4 shots), in mid-length rallies (5–8), or in extended exchanges (9+).Tennis
- Rally ToleranceIntermediateRally tolerance is a player's ability and willingness to extend rallies without forcing a risky shot. It shows in rally length and patience under pressure.Tennis
- Recovery StepIntermediateThe recovery step is the movement right after hitting a shot. It returns the player to the best defensive or offensive base before the next ball.Tennis
- Recovery to Center CourtIntermediateRecovery to center court is moving back to a balanced base position after a shot. That base covers the widest range of the opponent's likely replies.Tennis
- Return of Serve PositioningIntermediateReturn of serve positioning is how deep and how far to one side a returner stands. It is set to counter the server's pace, spin, and typical patterns.Tennis
- Rushing the Split StepIntermediateRushing the split step means landing from the hop before the opponent's contact. It leaves the player flat-footed, unable to react to the shot's direction.Tennis
- Second ServeIntermediateThe second serve is the follow-up attempt after a fault. This requires enough spin and margin to give the serve a wide safety margin while still limiting the returner's options.Tennis
- Second Serve SpinIntermediateSecond serve spin is the extra rotation a player adds to the follow-up delivery after a miss. It raises net clearance and margin for error.Tennis
- Semi-Continental Grip (Volley)BeginnerThe semi-continental grip sits between a continental and an eastern forehand. At net, some players use it to balance both volleys without moving the hand.Tennis
- Semi-Western GripBeginnerThe semi-western (base knuckle on bevel 4) is the most popular modern forehand hold, balancing topspin capability with comfortable contact across a wide range of ball heights.Tennis
- Serve and VolleyAdvancedServe and volley is a tactical pattern in which the server rushes to the net immediately after delivering the serve, intending to end the point with a first or second volley.Tennis
- Serve RoutineBeginnerA serve routine is the consistent pre-serve sequence — bouncing the ball, breathing, positioning the feet — that helps players enter a calm, focused state before every delivery.Tennis
- Serve Toss PlacementBeginnerServe toss placement is where the ball is released relative to the body. It determines which serve types are physically possible to hit from that toss.Tennis
- Serve-Plus-One PatternIntermediateServe-plus-one is a pattern where the server plans the shot after the serve before the point starts. The serve sets up a predictable, attackable ball.Tennis
- Shanking the Ball (Tennis)BeginnerA shank happens when the ball hits near the racquet's throat or frame edge instead of the string bed. It flies off at an hard to predict, often sharp angle.Tennis
- Short Backswing CompensationIntermediateShort backswing compensation means shortening the backswing under time pressure to force contact "on time," losing racquet-head speed and stored energy.Tennis
- Shot SelectionIntermediateShot selection is the real-time choice of shot type, direction, pace, and spin. It depends on court position, ball height, opponent location, and score.Tennis
- Sidestep / ShuffleBeginnerA sidestep or shuffle moves the player sideways while facing the net. The feet never cross, so the player stays balanced and ready to load for a groundstroke.Tennis
- SliceBeginnerIn tennis, a slice is a backspin shot hit high-to-low through the ball, for a low, skidding bounce. A golf slice, by contrast, is a curving mishit.Tennis
- Slice ServeIntermediateA slice serve adds sidespin by brushing around the outside of the ball. From a right-hander, it curves away from the deuce-side returner and stays low.Tennis
- Split StepBeginnerA split step is a small hop timed to the moment your opponent strikes the ball. It primes your legs to push off explosively in any direction.Tennis
- Straight-Arm ForehandAdvancedA straight-arm forehand keeps the hitting arm extended, not bent, through the forward swing. The longer lever adds racquet-head speed from body rotation.Tennis
- Straight-Back BackswingBeginnerA straight-back backswing moves the racquet straight back on a flat path, with no loop. It favors simplicity and timing control over racquet-head speed.Tennis
- String GaugeAdvancedString gauge is the thickness of a tennis string measured in millimetres or gauge numbers, with thinner strings providing more spin and feel and thicker strings offering greater durability.Tennis
- String TensionIntermediateString tension is how tightly a racquet is strung, in pounds or kilograms. It shapes the string bed's trampoline effect, control, and power.Tennis
- SwingweightProSwingweight measures how heavy a racquet feels when swung, accounting for where its mass is distributed. Higher swingweight gives more plow-through and power but is harder to maneuver.Tennis
- T-ServeIntermediateA T-serve is aimed at the center service line. It uses the shortest path for speed and takes away the returner's easiest angles.Tennis
- Tiebreak StrategyAdvancedTiebreak strategy is how players adjust tactics for a tiebreak's short, high-pressure points: serve selection, return aggression, and side-switch pacing.Tennis
