Curling Delivery Slide Stability Test: Measuring Lunge-Hold Sway
A stone drifting wide despite consistent weight often traces to slide-hold sway. An IMU protocol for measuring mediolateral wobble in the curling delivery.
Hammer Throw Turn Tempo: An IMU Protocol for Rhythm, Not Just Peak Speed
Turn tempo, not peak turn speed, separates clean hammer throws from stalled ones. The IMU protocol for measuring turn timing and rhythm consistency.
Measuring Handball Jump Shot Release Velocity With an IMU: Separating Arm Whip From Body Momentum
Jump shots leave the ground before release, so arm whip has to cover what body momentum can't. Dual-IMU protocol, benchmarks, and 2 cited handball studies.
How to Track Kettlebell Swing Velocity and Power with an IMU Sensor
Kettlebell swing velocity depends on where you mount the IMU: bell, wrist, or hip. Placement protocols, load benchmarks, and 2 cited studies.
Lacrosse Shot Speed Without a Radar Gun: Separating Crosse Sweep Velocity From Release Timing
Estimate lacrosse shot speed without a radar gun. See the crosse-sweep vs. release-timing IMU protocol, benchmark bands, and 2 cited studies behind it.
How to Measure Snatch Turnover Velocity with IMU: Separating Technical and Strength Bottlenecks
Same second-pull speed, different misses. Track turnover velocity with IMU to find out if the limiter is pull-under speed or raw second-pull strength.
Taekwondo Roundhouse Kick IMU Velocity Test: Quantifying Kick Power by Foot Angular Speed
Shin-mounted IMU tracks peak angular velocity per kick, no weight-sensing target needed. Full protocol, skill-level bands, and 2 cited biomechanics studies.
Why a Wrist-Worn Sensor Under-Reads Vertical Jump Height
A wrist-mounted jump sensor tracks your arm swing, not your center of mass, and that mismatch quietly shaves centimeters off every jump. Here is the fix.
How to Measure Pitcher Arm-Slot Consistency with IMU: Catching Fatigue Before Velocity Drops
Arm slot drifts before velocity does. Learn the wrist-IMU protocol, drift thresholds, and 2 cited studies behind catching pitcher fatigue early.
Biathlon Shooting Stability Under Fatigue: A Post-Ski IMU Sway Test Protocol
Test rifle stability right after skiing, at 85%+ max heart rate. A muzzle-sway IMU protocol, position norms, and 2 cited biathlon studies with limitations.
How to Measure BMX Gate Start Power: A Crank and IMU Protocol for the First Three Pedal Strokes
BMX gate starts are decided in 3 pedal strokes. Get the crank+IMU protocol, power benchmarks, and 2 cited studies behind measuring the first-stroke burst.
Canoe Slalom Reverse Gate Power Test: Measuring Deceleration-to-Reacceleration Burst
Canoe slalom power test data hides in the reverse gate. Measure the deceleration-to-reacceleration stroke burst with a field IMU protocol and 2 cited studies.
