Over-rotation isn’t just a mechanical issue—it’s a sensory blind spot. The KAT trains athletes to feel and control the edges of rotation.  The KAT responds with beeps and buzzes, so athletes learn to control their acceleration and deceleration.  

Here's how:

1. Live Feedback on Rotational Limits:

   KAT sensors worn on the torso and/or  hips can be calibrated to beep and  buzz when the athlete exceeds a preset rotational angle. This helps them recognize and  self-correct without relying on mirrors or delayed video review.

2. Builds Rotational Awareness:

   Most athletes don’t know they’re over-rotating. KAT gives instant haptic feedback when the athlete rotates too far, helping them identify and memorize the optimal range of rotation for their swing or throw.

3. Drills with Constraints:

   Coaches can design drills using the KAT to limit over-rotation—e.g., tee work, soft toss, or dry throws—where the athlete receives a buzz if they open up too much or too soon. This encourages staying closed longer and driving through the ball.

4. Progressive Repatterning:

   As the athlete trains with KAT, they gradually replace over-rotating habits with connected, rotationally efficient movement—maximizing power, control, and durability.

   
   

Unnecessary head movement affects both balance and vision. The KAT can be worn on a headband or clipped to a ball cap to detect and alert the wearer to even subtle head movement

1. Set KAT to stay quiet when the head stays still through the stride. KAT Beeps and buzzes when the head deviates from neutral.

2. Alerts athlete to compensatory patterns by triggering haptic cues so the athlete can self correct.

3. Identify weaknesses in core stability by using longer sets wearing the KAT, (i.e. induce fatigue and look for feedback in later reps) so the athlete learns what postural integrity feels like in real time, especially under fatigue

   
   

Stride length sets the hitter’s base. Too long = overextended and off balance. Too short = jammed and late. A consistent stride helps keep the hitter centered and stable.

1. Immediate Feedback on Overstriding or Understriding:

   Mount the KAT on the back calf. Set it to buzz when the stride extends too far or cuts short — providing instant feedback when stride length compromises balance or timing.

2. Reinforces Optimal Load-to-Land Distance:

   When the athlete lands with consistent, controlled stride length, the KAT stays quiet. This reinforces efficient lower body timing and spacing without overthinking mechanics.

3. Improves Lower-Body Sequencing:

   Proper stride length sets up hip rotation and weight transfer. KAT alerts help correct early reaches, collapsed strides, or inconsistent land positions that throw off the kinetic chain.

4. Customizable Drill Constraints:

   Use with mirror drills, tee work, or soft toss. Coaches can pair visual cues (e.g., tape line) with KAT buzzes to lock in a repeatable stride that supports explosive hitting mechanics.

   
   

Pelvic tilt control is essential in baseball and softball hitting because it maintains proper spine angle, builds tension between the hips and torso, and allows for more powerful, adjustable swings. Losing that tilt early disrupts timing, reduces power, and increases strain on the lower back.

1. Maintains Proper Spine Angle:

   Pelvic tilt supports forward trunk posture and stabilizes the spine during the swing. The KAT can be placed on the beltline to buzz when the hips dump under or lose tilt early.

2. Builds Tension for Rotation:

   Proper tilt creates separation between the hips and torso, powering rotational force. KAT feedback helps athletes feel when they’ve lost this tension too soon.

3. Improves Swing Efficiency & Adjustability:

   Holding tilt allows hitters to stay in their legs and adjust to different pitch heights. Buzzes cue posture collapse, reinforcing a more stable base through contact.

4. Reduces Lower Back Stress:

   Early loss of tilt often leads to lower back hyperextension. By alerting athletes to those posture shifts, KAT protects movement integrity and promotes safer mechanics.

This is where the KAT is most powerful, because it’s not a one-size-fits-all gadget. It’s a feedback framework. Any coach or athlete can build their own “technique-fix drill” around it by following a simple design process using the Advanced Dashboard: You decide what technique or movement patterns to address.

1. Define the 'Flaw':

   Pick one specific issue to fix and phrase it as a yes/no question the athlete can feel:

   “Did my stride land on target?”

   “Did I stay tall through release?”

   “Did I keep my hands connected?”

   
   

2. Attach the KAT:

   Attach the sensor where the mistake 'shows up':

   • Hip/stride leg → stride direction or foot angle

   • Elbow → arm path or slot

   • Torso → posture, rotation, or head pull

   • Ankle → weight shift or balance

   • Wrist → casting or early release

   
   

3. Set the Buzz Rule:

   Choose what you want the athlete to feel:

   • Buzz = mistake (Habit Break Mode)

   • Buzz = correct (Instruction Mode)

   
   

   Examples:

   • Buzz if stride foot crosses midline

   • Buzz if elbow drops too low

   • Buzz if torso opens too early

   
   

4. Run the Drill:

   Start with dry or slow reps, then add progressively challenging tasks

   Athlete's goal = “quiet reps” (no buzz = good rep).

   Once consistent (80–90% clean), remove the KAT and return to game-like settings.

   
   

The KAT teaches self-correction with different buzzes based on torso position. Here's how:

1. Immediate Feedback on Bad Posture:

   The KAT can be placed on the sternum, beltline, or mid-back. It buzzes when the torso tilts, opens too early, or pulls offline. This gives the athlete a physical “alert” in the moment—something video and verbal coaching can’t provide in real time.

2. Quietly Reinforces Good Habits: Staying Stacked:

   By staying silent when the athlete maintains a strong, upright posture through stride and release, the KAT rewards proper alignment through feel—not external correction.

3. Builds Proprioceptive Awareness:

   The athlete begins to internalize what a “stacked” and stable posture feels like. Use for only a few reps before throwing to reinforce upright delivery and reduce trunk compensation.

4. Customizable Constraints for Drills:

   Coaches can adjust the KAT’s sensitivity (how much tilt or twist triggers a buzz) and use it during dry drills, balance work, or bullpen sessions to eliminate postural breakdowns while keeping the athlete focused on feel.

Pelvic tilt is crucial in baseball hitting because it maintains proper spine angle and creates tension between the hips and torso, which powers rotational force. Losing that tilt too early reduces swing efficiency, adjustability, and can increase stress on the lower back.

1. Immediate Feedback on Pelvic Mistiming:

   The KAT can be placed on the beltline or lower back. It buzzes when the pelvis dumps backward (posterior tilt) too early or excessively, giving hitters a real-time signal when they lose hip posture.

2. Quietly Reinforces Good Pelvic Posture:

   When the athlete maintains forward pelvic tilt into rotation—keeping the hips “loaded”—the KAT stays silent. This reinforces proper posture through feel, not mechanical overthinking.

3. Builds Proprioceptive Awareness:

   Athletes begin to sense what “staying hinged” or “keeping the pelvis stacked” feels like during the swing. A few focused reps before BP can lock in the hinge pattern without needing constant coaching.

4. Customizable Constraints for Drills:

   Coaches can adjust KAT sensitivity to buzz on excessive tilt or early extension. Use during dry swings, tee work, or live rounds to sharpen pelvic control and reduce early posture loss.

The KAT can be worn on a headband or clipped to a ball cap to detect and alert the wearer to even subtle movement patterns of head wobble. It trains athletes to:

1. Set KAT to stay quiet when the spine and head are aligned during all phases of the swing or pitch. KAT Beeps and buzzes when the head deviates from neutral.

2. Alerts athlete to compensatory patterns by triggering haptic cues. Athlete can self correct.

3. Identify weaknesses in core stability with longer sets, (i.e. induce fatigue and look for feedback in later reps) to learn what postural integrity feels like in real time, especially under fatigue

   
   

Stride length sets the hitter’s base. Too long = overextended and off balance. Too short = jammed and late. A consistent stride helps keep the hitter centered and stable.

1. Instant Feedback on Overstriding or Understriding

   The KAT can be placed on the stride leg, front hip, or ankle. It buzzes when the stride is too long, too short, or mistimed—helping athletes feel the flaw in real time.

2. Reinforces Consistent Timing and Balance

   Proper stride length = stable base + efficient weight transfer. The KAT stays quiet when the hitter lands cleanly, reinforcing balance without overthinking mechanics.

3. Improves Swing Direction and Adjustability

   A repeatable stride supports directional force and plate coverage. KAT alerts prevent early lunging or collapsing, keeping the hitter centered and adjustable to pitch location.

4. Builds Repeatable Launch Position

   Consistent stride length creates a repeatable load-to-land sequence. Over time, hitters internalize their ideal stride pattern, boosting timing, confidence, and barrel accuracy.
