DECELERATION specific isometric exercises acutely enhance change of direction performance in academy ⚽️ players

✔️ 8th min most pronounced gains & with early DEC-ISO position

✔️ Application to pre-training or competition warm-ups for COD sports 🏈⚽️ 🏀👇

Influence of max linear deceleration on lateral deceleration & shuffle performance in NCAA power 4 🏀

10 teams, 124 players

📌 10m ADA Test
📌 5-5 Lateral Shuffle Test

✔️ Max linear deceleration differentiated lateral decelerstion ➕ shuffle performance

🚨 Biomechanical & neuromuscular performance requirements of horizontal deceleration…

📌 High Impact Forces ⚡️
(2.7 x ⬆️ than acceleration)

📌 Braking for Rapid COD 🔑

📌 High Eccentric Muscle Forces 🟰 Risk of Damage

📌 Braking Kinematics 🦵

Developing the qualities needed to DECELERATE & BRAKE rapidly🏈

What a great few days at the Elite Football Rehab Conference in Indianapolis 🇺🇸

⚡️Bonus: Got to watch the NFL combine, and learn from some great performance practitioners!!

Thanks to @erikMeira for the invite

🚨 BRAKING step forces in a 505 change of direction test (high speed deceleration)

Here we show data on ALL braking steps…

🔎 Brake Step 1
🔎 Brake Step 2
🔎 Brake Step 3
🔎 APBS
🔎 PBS
🔎 FFC

Forces highest in early braking steps!!

The biggest limiter of your speed is the ability of your BRAKES❗️

- Can I STOP❓🧠

- How much braking FORCE can I tolerate❓🧠

[Damian Harper, PhD @DHMov]

DECELERATION is a multi-step movement skill …

Each BRAKING step brings unique physiological + biomechanical demands

🔴 Braking from lower speeds
🔴 Braking from higher speeds

🟰differing demands…

Hamstring injuries in multi-directional speed sports...not all SPRINT related❗️

⚽️ 31 % Braking Stopping
🏉 18% Decelerating

🔎 Trunk & hip flexion with knee extension

🟰High eccentric strain

Braking movements with high eccentric force could be tools in hamstring injury ⬇️

⚽Tactical evolutions predicted on models of high-intensity pressing = greater exposure to intense decels & braking forces

🔑 BRAKING PERFORMANCE CAPABILITIES

⬆️ Game specific speed
⬇️ Fatigue
⬇️ Injury-Risk
