Wondering what it will take for the “academic revolt” to happen. If not this, then what? Service is one thing, but estimates like these reveal something wayyyy more aggressive. JMO

Spurs have carried out an investigation into whether the Tottenham Hotspur Stadium's retractable pitch is contributing to the club's ongoing injury crisis 💬

90+5 we are serious

@21JacksonBurns had himself a day on the bump!

Training stimulus = the motion athletes create/terminate (momentum; m*v)

Training strategies = control load moved (mass) & the velocity of the load moved

For sport transfer: create ⬆️ momentum in training vs sport (don’t lust for velocity)

Don’t miss the forest for the trees.

@JeremyHHarrison @Tony_Villani_ This level of BJ assessment is akin to measuring CMJ with tape marked on a wall.

BJ has been assessed on force plates just like CMJs- they just require multi axis force plates

The tape measured dist of a BJ fails to account for body control/position b4 + after flight

Helluva performance on the bump today!

@StrengthDebates Learn to paint corners at 90 mph and lose the obsession with three-digit heaters

[John Harry, PhD @johnharry76]

@spikesonly Think of this as a new way to apply specificity without over complication. Focus on physics rather than unnecessary technical minutiae

[John Harry, PhD @johnharry76]

@spikesonly I think not. Step pattern and distance are coachable strategies on the track. You don’t have to run that same way when running with resistance (generally). It’s about increasing capacity to apply impulse, which transfers to performance when refining on track strategies

[John Harry, PhD @johnharry76]

@spikesonly Ultimately, I think the goal of resisted training has been over complicated

[John Harry, PhD @johnharry76]

@spikesonly Jotted this down real quick. Hopefully it makes sense:

[John Harry, PhD @johnharry76]

@spikesonly I don’t want to minimize value of load & overvalue speed of the exercise. I want to value motion created

Ex: a slower run with heavy load and a faster run with lighter load can have the momenta, but the faster run will have higher KE because the squared velocity.

[John Harry, PhD @johnharry76]

@firecashman @mrdougellin I’d rather watch Walsh’s Medellin

[John Harry, PhD @johnharry76]

@spikesonly Aaaaaaaaaannnnnddddd it will be in legit T&F sprinters and hurdlers

[John Harry, PhD @johnharry76]

@spikesonly We will be exploring Momentum-based load selection and load-specific run distances to maximize the stimulus and minimize wasted work

[John Harry, PhD @johnharry76]

More fun exploring elite pitching kinematics in the @TTU_Biomech and @TTU_Baseball pitching lab!
