Box Jumps vs Drop Jump: Understanding Eccentric Impulse, Force Orientation and Specificity in Plyometric Training

Plyometric training is often simplified into general categories, where exercises are selected based on perceived intensity or tradition rather than on their true mechanical demands.

However, different jump exercises impose distinct neuromuscular constraints, force characteristics and coordinative requirements.

The comparison between jump from box and drop jump provides a clear example of how seemingly similar exercises can produce very different adaptations.

Understanding these differences is essential for designing effective strength and conditioning programmes for sprinting, jumping and high-performance sport.

Eccentric Force: The Key Mechanical Difference

Force plate analysis revealed that the drop jump generated a substantially higher eccentric force compared to the jump from box.

A New Edition in Bergamo, Italy

The wait is over.

After the success of last year’s edition, Speed Festival returns on October 18–19, 2025, and once again we’ll gather at the CUS Bergamo sports center, just a few minutes from the Milan-Bergamo Airport — in the heart of northern Italy, but with a truly international spirit.

Over the past months, we’ve listened, reflected and reimagined what Speed Festival could become.

And now, we’re ready to launch a new edition — bolder, deeper, and even more focused.

One Theme: Speed Development

This year, we’re diving into a single, powerful theme:

The development of speed in three key areas — sprinting, horizontal jumps and hurdles.

Because speed is not just an ability. It’s a skill. A system. A language. And we want to explore it from every angle: technical, biomechanical, neuromuscular and practical.

But don’t worry — while the theme evolves, the core remains the same.

Science Meets Practice
