How Does Approach Speed Impact Deceleration Forces? 🛑🏃‍♂️💨 This figure shows vertical (top) and horizontal (bottom) ground reaction forces during deceleration — comparing athletes braking from: 🔴 100% max speed 🔵 85% speed 🟢 70% speed …and across the first, second, and…

💪 Which Lower-Limb Muscles Work Hardest During Deceleration? 🛑🏃‍♂️ 📊 Forces are normalised to body weight (BW), and velocities are shown relative to each muscle’s resting length. 🦵 The duration of muscle lengthening is presented as a percentage of ground-contact time. ⚠️…

📈 How Do Ground Reaction Forces Differ Across Sprint and Deceleration Tasks? 🏃‍♂️💨🛑 This chart compares vertical (left) and horizontal (right) ground reaction force profiles across: 🔴 Deceleration 🔵 Acceleration 🟡 Slow constant-speed running ⚪️ Fast constant-speed running…

🚨 The 3 Phases of Ground Contact in Horizontal Deceleration 🏃‍♂️💥 Understanding how the body absorbs force during deceleration is key for performance and injury reduction. In this visual breakdown: 🔴 High-load and 🟡 moderate-load areas are highlighted across the lower-limb…
