12 weeks of progressive resistance training (3x1 h sessions/week) reduced diastolic function in men, indicating potential cardiac stiffening.

12 weeks of cardio in the same men tended to improve diastolic function.

Counterbalance RT with cardio.

[Håkan Andersson @sprintcoachSWE]

When the “competition” between different producers of force plates has lead to reporting 50 different metrics from at simple vertical jump the situation has become rather absurd. Shouldn’t the focus be on a few important KPIs in different sports...

High speed running:

Does it cause the injuries, or does it prevent them?

Is the 4x4 minute "Nowegian" method the best interval workout to increase Vo2max?

No. I explain why here... on the reality of hard workouts:

Players with larger ASR:
⬆️sprint performance
⬇️relative running intensity
⬆️distances above MAS

To novice runners, a marathon is often considered the ultimate challenge. A 5k is the entry event.

But... running a good 5k can be much more challenging. You are riding a line, it's hard from the get go.

We are biased towards equating distance to challenge.

The Relationship Between Strength Qualities & Sprint Acceleration Performance

Research from Claire Brady, University of Limerick & the Sport Ireland Institute

What strength qualities underpin acceleration speed in field sport athletes?

Methods:
Field sport athletes (n=26)
Speed @ 5/10/20/30m splits
Isometric Squat (bilateral)
CMJ
RSI (10-5 RJT)

Headlines:

1⃣ 3 principle components identified in dataset:

🔸Maximal isometric strength & relative iso strength
🔸Explosive strength: Isometric force (<200ms)
🔸Sprint performance & SSC abilities (CMJ, RSI)

2⃣ No relationship was observed between Maximal Isometric Strength (or max. iso relative strength) and sprint performance at any sprint distance

3⃣ Athletes with better Explosive Strength (top quartile in force @ 100ms) had better performance in early phase acceleration (0-5m) than those with poorer explosive strength (bottom quartile athletes in F @ 100ms)

4⃣ Slow SSC Fast Dynamic Strength was sig. correlated with all sprint distances with the strongest relationship observed at 10-20m. The athletes with best CMJ (top quartile) were significantly faster at 10-20m compared with athletes with the poorer CMJ (bottom quartile)

5⃣ Reactive Strength was significantly associated with all sprint distances >5m (10/20/30m) with strongest relationship at 20-30m. The athletes with best RSI (top quartile) were significantly faster at 5-10m, 10-20m and 20-30m compared with athletes with the poorest RSI (bottom quartile)

🦘What makes YOU fast?🏃🏽‍♂️

When looking at the best players in the world , we can notice them maximise different elements of the running cycle.

The most robust players can utilise them all.

Question is, which one is the best model?

[Danny Lum, PhD, CSCS, ASCA L2 @DannyLum82]

Our study that investigated PAPE using ISO pull on power clean performance has been published online @IJSPPjournal . We found small to moderate potentiation effect across 3 sets of ISO pull + power clean contrast sets.

A modern movement performance evaluation &amp; velocity targets? (presented by @jpnsatok) The method is rather straight-forward, easy numbers...

☑️1.0 m/s for the POP-100V (0.9 in this case)
☑️2.0 m/s for the POP-200V
@movefactorx

Measuring "RFD" with logic &amp; simplicity is key.

🚨New thought provoking study by Sugisaki et al on 50 force plates + @1080motion “Influence of horizontal resistance loads on spatiotemporal and ground reaction force variables during maximal sprint acceleration” https://t.co/ugy5wnfmiv
Some thoughts 🧐
IMO, everyone whos done a resisted sprint study with spatiotemporal and kinetic analysis should read this as we might have used less optimal methods to determine the influence of additional resistance (including our study). This study standardized based on the velocity, and not distance or time. The results also better explain why heavy vs light loads work for specific phases without potentially negative consequences on technique (although the individual should always be considered).

🚩The reasons your players get stronger but not faster. …..

You ONLY gym , to increase mass.😟

You ONLY gym to put more weight on the bar. 🥲

You think Velocity Based Training will transfer to game actions.😅

You disproportionally develop hips and thighs and neglect ankle springs.🤬

Instead….

💡YOU SHOULD GYM TO JUMP!💡

Don’t get me wrong ….

We want more mass 🍑 and we want a heavy bar 🏋🏽‍♂️

💡…but all so we can focus on shocking the body with plyometrics.💡

We create tissue/bone tolerance with mutli directional extensive jumps. 🐇

Then we drop from heights and learn how to coordinate compression. 🪗

Then we rebound from heights and learn to dominate the collision. 🪂

First the body says “hold up, I am scared , so I will crumble for safety”

Then the body says “yo, I been here before, I am not scared, I will let you use your super powers”

Unlock your players super powers with plyometrics and special strength training!

Everyone can run faster , We can show you how!
