What is the DSI and how can knowing it benefit Olympic weightlifters?
Well, the Dynamic Strength Index (DSI) = Counter Movement Jump peak force ÷ Isometric Mid Thigh Pull peak force.
This gives you a result in one of three zones - greater than 0.8, less than 0.6 or between the two.
There is no “good” or “bad” result for your DSI. It is just information you can use to help inform the focus of your training. It is always important to apply your individual context when interpreting ANY testing result.
What does your result mean?
DSI > 0.80 — Maximal Power Expression: You are currently expressing as much power as your current strength levels allow you too. You would most likely benefit from increasing your absolute strength levels IF you want to get more powerful.
0.60–0.8 — Your Power & Strength Expression are Balanced: This means you are expressing your current strength and power evenly. To continue to improve, you can train both.
DSI < 0.60 — Minimal Power Expression: You are currently NOT expressing the level of power your current level of strength has potential to. You would benefit the most from working on ballistic and power training.
There is always a little nuance to this, and that is what we will chat about during the workshop.
