- Line Call EtiquetteIntermediateIn self-officiated play, the side of the court where the ball landed makes the call, benefit of the doubt goes to the opponent on close or unsure calls, and calls are made immediately, not after the fact.Pickleball
- Line Drive RateIntermediateLine drive rate (LD%) is the percentage of batted balls classified as line drives (typically 0–25° launch angle with hard contact). This means the batted-ball type with the highest expected batting average.Baseball
- Lineup StrategyAdvancedLineup strategy is the deliberate construction of the batting order to maximize run production. This means pairing on-base skills at the top with power at the middle spots and reliable contact throughout.Slow-Pitch Softball
- LoadBeginnerThe load is the small backward gathering of the hands and weight just before the swing initiates. This means coiling the body to store elastic energy that fires into the ball when the swing begins.Baseball
- LoadBeginnerThe load is the backward weight shift and hand coil that sets the hitter in a ready, wound-up position before initiating the swing. In slow pitch, the load must happen early and hold while the long-arcing ball descends.Slow-Pitch Softball
- Load Timing (Hitting)IntermediateLoad timing is when and how a hitter shifts weight back and coils the upper body in preparation for the swing, synchronized to the pitcher's delivery rather than started on a fixed internal clock.Fast-Pitch Softball
- LobIntermediateA lob is a high, arcing shot designed to clear a net player's reach, either buying time defensively or winning the point offensively with a topspin arc that lands near the baseline.Tennis
- LobIntermediateA lob is a high-arcing shot hit over the opponents' heads, forcing them off the kitchen line and back toward the baseline.Pickleball
- LobBeginnerA lob is a high, deep shot hit over the net opponents to push them back from their attacking position. This means the most important defensive weapon in padel and the primary tool for reclaiming the rally from a losing position.Padel
- Lob DefenseBeginnerLob defense is using a high, deep shot over an approaching or net-positioned opponent to buy time, reset the point, or force a difficult overhead.Tennis
- Lob to the GlassIntermediateA lob to the glass is a defensive or neutralizing lob deliberately aimed to land and die close to the back glass rather than simply hit deep. This uses the wall to compress the ball's remaining bounce and deny the net pair a comfortable, well-timed overhead.Padel
- Lob Wedge ShotIntermediateA lob wedge shot uses the most-lofted club in the bag (58–64°) to produce a high, soft-landing shot. This means most effective when you need to carry a hazard and stop quickly on a small target.Golf
- Local RuleIntermediateA local rule is a course- or competition-specific modification adopted by the committee running play. This means commonly covering embedded balls, temporary conditions like winter rules, or unique course features not addressed by the standard Rules of Golf.Golf
- Loft GappingIntermediateLoft gapping is checking that consecutive clubs in a bag. This means especially wedges. This means are spaced by consistent loft and yardage increments. As a result, there are no large distance gaps or overlapping distances between neighboring clubs.Golf
- Long Backswing Timing IssueIntermediateA long backswing timing issue occurs when the backswing takes longer to complete than the ball allows. This forces a rushed or unfinished forward swing regardless of how clean the backswing shape looks in isolation.Tennis
- Long Toss ProgramIntermediateA long toss program is a structured throwing routine in which a player gradually increases throwing distance well beyond normal game distances, then works back down, used to build arm strength and as part of an overall arm-conditioning routine.Baseball
- Loop BackswingIntermediateA loop backswing takes the racquet back and up before dropping it down into the forward swing. This uses the circular path to build racquet-head speed and rhythm.Tennis
- Loss of Balance on Stretch ShotsIntermediateLoss of balance on stretch shots happens when a wide, low, or hard-hit ball forces a player to reach beyond a stable base. This causes the center of mass to fall away from the shot at contact.Tennis
- Loss of PostureIntermediateLoss of posture is any change in spine angle, knee flex, or forward bend from the address position during the swing. This shifts the swing's plane and low point away from where they were originally set.Golf
- Lost BallBeginnerA ball is officially lost if it isn't found within three minutes of the group beginning to search for it. This means once that window closes, the golfer must take stroke-and-distance relief, replaying the shot from its original spot plus a one-stroke penalty.Golf
- Low Draw ShotAdvancedA low draw shot is a deliberately low-launching, right-to-left curving shot that runs out by a lot on landing. This is useful for navigating under obstacles on the right side of a hole or maximizing roll on firm fairways.Golf
- Low PointProLow point is where the clubhead reaches the bottom of its arc through impact. Controlling it — keeping it at or just ahead of the ball with irons — is the basis of pure contact.Golf
- Low-Spin MissAdvancedA low-spin miss is a shot with sharply reduced backspin, usually from a thin or low-face strike, that flies with an unstable, hard to predict, "knuckling" trajectory rather than the expected controlled flight.Golf
- Lower-Body SlideIntermediateA lower-body slide is excessive lateral movement of the hips toward the target during the downswing, without a matching rotation, that pushes the swing's low point too far forward and leaves the upper body behind.Golf
- Lunging (Batting)BeginnerLunging is a timing fault where a hitter commits their weight and stride forward too early. This means usually. At the same time, trying to catch up to velocity or guessing a pitch is coming. This means draining rotational power before the swing even begins.Baseball
- Mallet PutterBeginnerA mallet putter uses a larger, often geometric head shape with weight pushed to the perimeter for high forgiveness and, frequently, a face-balanced design suited to a straighter-back-and-through stroke.Golf
- Manufacturing RunsIntermediateManufacturing runs is the execution of a sequence of small offensive actions. This means walks, bunts, steals, contact hits, and productive outs. This means that collectively score a run without requiring extra-base power.Fast-Pitch Softball
- Match Play vs Stroke PlayBeginnerStroke play scores every shot across the whole round for a cumulative total. Match play scores hole by hole, awarding each hole to whoever takes fewer strokes on it. As a result, a single bad hole only costs one point, not a pile of extra strokes.Golf
- Match Tiebreak (10-Point)BeginnerA match tiebreak (or "super tiebreak") is a first-to-10-points breaker, won by two clear points, played instead of a full third set in many doubles and some singles formats.Tennis
- Measured ValueBeginnerA measured value is a number that came from a real sensor or instrument. This means a launch monitor, radar gun, or wearable. This means and was not inferred or estimated from video or rules.Analysis Concepts
- Mercy RuleBeginnerThe mercy rule is the informal name for the run rule. This means the rule that ends a game early when the scoring gap becomes too large to be competitive, protecting player safety and league scheduling.Slow-Pitch Softball
- Middle BallIntermediateA middle ball is a shot aimed directly between two opponents in doubles, designed to create confusion about who should take it and generate communication errors.Pickleball
- Middle Infield Bunt CoverageIntermediateMiddle infield bunt coverage is the shortstop and second baseman's job of covering second and third base and backing up throws when the corner infielders and pitcher vacate their positions to field a bunt.Fast-Pitch Softball
- Middle Infield CommunicationIntermediateMiddle infield communication is the ongoing verbal and non-verbal coordination between the shortstop and second baseman. This means covering who takes cutoffs, who covers the bag on steals, and who has priority on shallow pop-ups. This means needed to avoid collisions and missed assignments.Slow-Pitch Softball
- Mis-Hit CausesBeginnerMis-hit causes fall into a small number of root categories. This means contact-point timing, footwork spacing, balance, and grip mismatch. This means and identifying which one applies is the fastest way to fix repeated mis-hits.Tennis
- Mis-Hit Diagnosis (Slow-Pitch)AdvancedMis-hit diagnosis is the process of tracing a weak or poorly directed batted ball back to its specific mechanical cause. This means timing, bat path, contact point, or body position. Instead of treating every bad swing the same way.Slow-Pitch Softball
- Mobile Motion CaptureIntermediateMobile motion capture is the process of using a smartphone camera and on-device pose estimation to track body movement in real time or from a recorded clip. This means no specialized hardware required.Analysis Concepts
- Mock / Demo DataBeginnerMock or demo data is pre-generated illustrative data used in product demos, onboarding flows, and feature previews. This means always labeled to distinguish it from real user data.Analysis Concepts
- Moment of Inertia (MOI)AdvancedMoment of inertia (MOI) measures a clubhead's resistance to twisting on off-center hits. This means a higher MOI keeps the face more stable at impact. This is why perimeter-weighted, forgiving clubs reliably retain more ball speed on mishits.Golf
- Momentum Shift in a MatchAdvancedA momentum shift is a noticeable change in which player is controlling the flow of a match, often triggered by a break of serve, a long game won on key points, or a run of consecutive games.Tennis
- Moon BallIntermediateA moon ball is a very high, heavily topspun groundstroke hit well above net height to disrupt an opponent's rhythm and buy recovery time without going as high or defensive as a full lob.Tennis
- Motion CaptureIntermediateMotion capture records a golfer's body movement in three dimensions, traditionally using reflective markers and multiple cameras, to build a precise digital skeleton of the swing for biomechanical analysis.Golf
- Motion LabBeginnerMotion Lab is the browser-based 3D motion analysis tool in SwingVantage that turns your video into a three-dimensional avatar and timeline, letting you rotate, scrub, and measure your swing without any installed software.Analysis Concepts
- Motor LearningIntermediateMotor learning is the scientific study of how the nervous system acquires, refines, and retains skilled movement. This means the theory underlying how practice actually changes your swing.Analysis Concepts
- Movement PatternIntermediateA movement pattern is the sequence of footwork steps a player uses to reach the ball, execute the shot, and recover to position. This means combining split step, approach steps, stance, and recovery.Tennis
- Movement SequencingAdvancedMovement sequencing is the timed order in which body segments accelerate and decelerate through a swing — correct sequencing multiplies speed; incorrect sequencing bleeds it.Analysis Concepts
- MulliganBeginnerA mulligan is an informal "do-over". This means hitting a second ball after a poor shot without counting the first one. This means that has no basis in the actual rules of golf and is purely a casual, friendly-round convention.Golf
- Muscle MemoryIntermediateMuscle memory is the process by which a motor pattern (the swing) becomes automatic through repetition. This means stored in the motor cortex and cerebellum. As a result, it can be executed without conscious thought.Golf
- Narrow StanceBeginnerA narrow stance places the feet closer together than shoulder width, trading some stability for more freedom of hip rotation. This means typically used on shorter shots like chips, pitches, and short irons.Golf
- Natural Gut StringAdvancedNatural gut string is made from cow intestine and offers the highest elasticity, best tension retention, and greatest comfort of any string material, at a significant cost and durability trade-off.Tennis
- Net Approach TimingIntermediateNet approach timing is when a player moves forward to the net relative to their own shot and the opponent's reply, aiming to split step just as the opponent makes contact.Tennis
- Net ControlBeginnerNet control is occupying the forward zone of the padel court as a pair. This means the dominant attacking position from which volleys can be directed down at opponents and overheads can finish points. At the same time, the back pair is limited to defensive shots and lobs.Padel
- Net Dominance StrategyIntermediateNet Dominance Strategy is the core tactical framework of padel. This means both players in a pair occupy the net zone, control the point with aggressive volleys and smashes, and use positioning to force opponents into defensive lobs that can be punished.Padel
- Net Position Communication (Doubles)IntermediateNet Position Communication is how a padel pair coordinates their side-to-side and depth positioning at the net without necessarily speaking. This means mirroring each other's movement. As a result, the middle and the alleys stay covered as a unit rather than as two individuals.Padel
- Net Score vs Gross ScoreBeginnerGross score is the actual number of strokes taken. Net score subtracts a player's course handicap from that total, letting golfers of different skill levels compete on a fair, adjusted basis.Golf
- Net ZoneBeginnerThe Net Zone is the dominant attacking position in padel. This means the area closest to the net from which players can volley, smash, and put pressure on opponents without the glass walls being a factor.Padel
- Net-to-Back TransitionIntermediateThe Net-to-Back Transition is the movement a pair makes from the attacking net zone to the defensive back position when lobbed. This requires synchronized retreat, correct positioning, and immediate readiness to play off the back glass.Padel
- Neutral Ball FlightIntermediateA neutral ball flight is a shot that starts at the target and flies with minimal sideways curve, produced when the clubface angle and swing path are nearly matched at impact.Golf
- Neutral GripBeginnerA neutral grip has the lead hand rotated. As a result, 2–2.5 knuckles are visible at address and the trail hand's palm faces the target. This means the "middle" grip position that squares the face without extra hand manipulation.Golf
- Neutral Rally BallBeginnerA neutral rally ball is a moderate-pace, high-margin shot hit deep and crosscourt to maintain a rally without taking risk or conceding the point's initiative.Tennis
