556 terms
- Hit and RunIntermediateThe hit and run is an offensive play where the baserunner breaks toward the next base on the pitch, committing the defense. At the same time, the hitter makes contact to put the ball in play and protect the running runner.Fast-Pitch Softball
- Hit-and-RunIntermediateA hit-and-run is a play call in which a baserunner takes off toward the next base as the pitch is thrown. The hitter is required to swing and make contact. This means ideally putting the ball in play on the ground. This means to protect the runner.Baseball
- Hitch in the SwingIntermediateA hitch is an extra downward or backward dip of the hands after the load has already started forward, effectively creating a second, unplanned load that costs precious time against velocity.Baseball
- Hitting Off the Back FootIntermediateHitting off the back foot means the hitter's weight stays planted on the back leg through contact instead of transferring forward. This produces an arm-only swing with little rotational power.Slow-Pitch Softball
- Hitting Off the Front FootIntermediateHitting off the front foot means the hitter's weight has fully transferred forward before contact. This leaves no back-side push to power the swing and often causing early, weak contact.Slow-Pitch Softball
- Hitting Zone WidthIntermediateHitting zone width is how much room a hitter's bat path stays flat or near-flat through the contact area. This gives a wider window in which solid contact is still possible even with imperfect timing.Slow-Pitch Softball
- Home-to-First TimeIntermediateHome-to-first time is a stopwatch measurement of the seconds it takes a batter to travel from contact at home plate to touching first base, used as a standardized speed benchmark in evaluation and recruiting.Fast-Pitch Softball
- Hook ShotIntermediateThe hook shot is an attacking batting stroke played to a short-pitched, rising ball aimed at the body or head. This means the batter pivots and whips the ball to the leg side, often in front of square.Cricket
- Impact PositionIntermediateImpact position is the body and club configuration at the exact moment the clubface meets the ball. This means the single frame of the swing that determines ball flight more than any other point.Golf
- Improvement DeltaIntermediateAn improvement delta is the measured difference between a baseline value and the most recent measurement for the same metric. This means the hard number behind "did I get better?"Analysis Concepts
- In-Between Hop (Slow-Pitch)IntermediateThe in-between hop is the awkward mid-bounce moment when a ground ball is neither low enough to pick off the dirt nor high enough to receive comfortably. This means the hardest timing to field cleanly.Slow-Pitch Softball
- In-SwingIntermediateIn-swing is conventional swing bowling where the ball curves in the air from off to leg (in towards the body of a right-handed batter), often targeting the stumps or pads.Cricket
- In-to-OutIntermediateIn-to-out describes a clubhead travelling rightward across the target line as it meets the ball, for a right-hander. It is the delivery direction underneath draws, hooks and pushes.Golf
- Infield DepthIntermediateInfield depth is how far the infielders play from home plate. This means "in" (shaded forward to cut off a run) or "back" (standard depth to maximize range on ground balls and line drives).Slow-Pitch Softball
- Inside Pitch ApproachIntermediateThe inside pitch approach is the technique for hitting a ball on the inner third of the plate. This means pulling the hands in, getting the barrel through early, and driving the ball to the pull side.Fast-Pitch Softball
- Inside-Out ForehandIntermediateAn inside-out forehand is played by running around a ball that arrives on the backhand side and redirecting it with the forehand to the opponent's backhand corner.Tennis
- Interpreted ValueIntermediateAn interpreted value is a judgment or label that emerged from AI reasoning applied to raw data. This means such as 'likely timing issue' or 'probable hip stall'. Instead of from a direct measurement or a deterministic rule.Analysis Concepts
- Iron Contact PointIntermediateIron contact point is the specific spot on the clubface where the ball is struck. This determines ball speed, spin consistency. The direction of any gear-effect curve, independent of swing path and face angle.Golf
- JudgmentIntermediateJudgment in cricket batting is the ability to quickly decide which deliveries to play and which to leave, choosing the right shot for each ball bowled.Cricket
- Jump (Stolen Base)IntermediateThe jump on a stolen base attempt is how quickly and decisively a runner breaks toward the next base on the pitcher's first movement. This means the single biggest predictor of stolen base success.Baseball
- Kinematic ChainIntermediateThe kinematic chain is the sequence of body segments. This comes from ground to tip. This means through which force and speed are transferred in a swing, with each segment's energy amplifying the next.Analysis Concepts
- Kinetic ChainIntermediateThe kinetic chain in tennis is the sequential transfer of force from the ground up through the legs, hips, torso, shoulder, arm, and racquet, each segment accelerating the next to multiply racquet-head speed.Tennis
- Kinetic Chain BreakdownIntermediateA kinetic chain breakdown happens when the ground-up sequence of leg, hip, torso, and arm rotation is interrupted or skipped. This forces the arm to generate power on its own instead of receiving it from the body.Tennis
- Kitchen Line BattleIntermediateA kitchen line battle is the sustained exchange that happens once both teams have reached the non-volley zone line, combining dinks, speed-ups, and volleys until one side forces an error or opening.Pickleball
- Knock-Down ShotIntermediateA knock-down shot is an approach shot deliberately hit with a lower, more controlled trajectory than normal. This means usually with more club and a shorter, three-quarter swing. This means to fight wind or control distance more precisely.Golf
- Lag PuttingIntermediateLag putting is the deliberate strategy of prioritizing distance control over making a long putt, aiming to leave a short, stress-free second putt rather than attacking the hole aggressively.Golf
- Landmark TrackingIntermediateLandmark tracking follows the position of each detected body keypoint across consecutive video frames. This creates a time-series trajectory for every joint that enables timing and velocity measurements.Analysis Concepts
- Late Contact (Slow-Pitch)IntermediateLate contact happens when the bat meets the ball behind the ideal contact point. This means closer to or behind the back edge of the plate. This means usually producing weak contact to the opposite field or a foul ball.Slow-Pitch Softball
- Late Contact (Tennis)IntermediateLate contact means the racquet meets the ball behind the ideal contact point. This means usually behind the front hip. This means which robs the shot of pace, direction control, and spin.Tennis
- Late LoadIntermediateA late load is starting the weight shift and hand-back motion later than the pitch's flight time allows. This leaves too little time to complete a full, balanced swing before the ball arrives.Slow-Pitch Softball
- Late Split StepIntermediateA late split step lands after the opponent has already struck the ball, meaning the player is still airborne or resettling exactly when they need to be pushing off toward the shot.Tennis
- Launch AngleIntermediateLaunch angle is the vertical angle, in degrees above horizontal, at which the ball leaves the face. Together with spin it determines how high and far the ball flies.Golf
- Launch Angle (Batting)IntermediateLaunch angle in batting is the vertical angle the ball leaves the bat. Roughly 10–25° produces the hardest, most productive contact.Baseball
- Launch Angle (Slow-Pitch)IntermediateLaunch angle is the vertical angle at which the ball leaves the bat relative to the ground. This means too low produces ground balls, too high produces pop-ups. A moderate range produces line drives and gap shots.Slow-Pitch Softball
- Launch MonitorIntermediateA launch monitor is a device that measures ball and clubhead data at impact. This means ball speed, launch angle, spin rate, and club speed. This means using radar or camera sensors to quantify a shot instead of relying on how it looked.Golf
- Lead Arm BendIntermediateLead arm bend is excessive folding of the lead elbow during the backswing. This involves shortening the swing's radius and reducing the width and stored power a fully extended backswing would otherwise create.Golf
- Lead TimingIntermediateLead timing is when and how far a baserunner leaves the base in anticipation of a pitch being put in play or a steal attempt. This requires coordination with the pitcher's release point.Fast-Pitch Softball
- Lead WristIntermediateThe lead wrist is the wrist of the top hand (left for right-handers). Its position throughout the swing — especially at the top of the backswing and at impact — directly controls clubface angle and low point.Golf
- Leg Drive – PitchingIntermediateLeg drive is the forward force the pivot leg generates against the rubber to launch the pitcher's body toward home plate, forming the base of the kinetic chain the windmill arm circle rides on top of.Fast-Pitch Softball
- Leg Drive on GroundstrokesIntermediateLeg drive is the push off the ground during a groundstroke that initiates the kinetic chain, converting ground reaction force into upward and rotational energy that feeds into the hips, torso, and arm.Tennis
- Leg KickIntermediateA leg kick is a pronounced lift of the front knee during the load, used to build extra rhythm and stored energy before the stride and swing fire. This means a bigger, higher-risk trigger than a toe tap or no-stride approach.Baseball
- Leg-SpinIntermediateLeg-spin is a type of spin bowling where a right-arm bowler spins the ball from leg to off (from right to left as seen by the batter). This uses wrist rotation to impart heavy clockwise topspin.Cricket
- 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
- 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
- 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
- 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
- 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
- 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
