Today, we're going to explore depth jumps! Who can tell me what a depth jump is?
Isn’t that when you jump from a height and then try to rebound quickly?
Exactly! The depth jump involves dropping from a height of 30–60 cm and aiming for a fast rebound. Why do you think the amortization time is crucial?
Because if we take too long to jump back up, it won't be as effective?
Right! An optimal amortization time is less than 0.2 seconds. This ensures we effectively use the stretch-shortening cycle. Can anyone tell me what that is?
It’s the muscle's ability to generate more force by stretching before contracting, right?
Spot on! In practice, this helps athletes become more explosive. Remember, think ‘fast rebound’! Let's recap: Depth jumps work on fast reactivity and explosive rebounds.
Now, let’s talk about the Reactive Strength Index or RSI. Who knows what it is?
Is it a way to measure how quickly someone can jump after landing?
Exactly! RSI tells us how effective a jump is in relation to ground contact time. How is it actually calculated?
It’s jump height divided by the time you spend on the ground?
Correct! The formula is Jump Height (m) ÷ Ground Contact Time (s). Why do you think knowing your RSI is important?
It helps to see how well we can use explosive strength. If our RSI is high, that’s good, right?
Yes, it indicates good explosiveness! In our next session, we will dive deeper into its applications in training. Remember, RSI equals performance!
Drop and pop, don’t stop, to reach the top, keep your time a short hop!
Imagine an athlete jumping off a box and rebounding like a spring, ready to explode into the air—this is how depth jumps train the body!
D.R.E (Drop, Rebound, Explode) - Remember the steps to perform effective depth jumps.
R.S.I (Reactive Strength Index) - Remember it’s all about your Jump Height divided by Ground Contact time.

This section covers the fundamentals of jumping and plyometric training, emphasizing reactive strength and efficient technique for athletic performance.
Jumping and plyometrics are crucial components of athletic training, focusing on improving explosive power and lower-body strength. The section discusses protocols like depth jumps and the significance of the Reactive Strength Index in enhancing athletic performance.
Jumping and plyometrics form a vital aspect of athletic training aimed at improving explosive power and overall performance in sports. This section details specific techniques such as the depth jump protocol and introduces the concept of the Reactive Strength Index (RSI) as a tool for evaluating the effectiveness of plyometric training.
Understanding and implementing these jumping and plyometric techniques are essential in developing effective training regimens for various sports, enhancing both technique and athletic performance.
