What is the Reactive Strength Index (RSI)?

RSI measures explosive, reactive power, how well you absorb and rebound from landing. It is calculated from a drop jump and reflects your ability to produce force quickly, a key quality for sprinting, jumping, and other fast stretch-shortening movements.

How is RSI calculated?

RSI = jump height / ground contact time, both during a drop jump. Enter your jump height and the time your feet spend on the ground between landing and take-off, and the calculator returns your RSI along with a rating.

What is a good RSI value?

RSI is typically expressed in metres per second; values around 1.5-2.0 are good and above roughly 2.5-3.0 indicate excellent reactive strength, while below 1.5 suggests room to improve. The aim is high jump height with minimal ground contact time.

Calculator ng Reactive Strength Index

Ang Reactive Strength Index ang pangunahing field test ng pasabog at reaktibong lakas para sa mga tumatalon at sprinter. Ilagay ang taas ng iyong drop-jump at ang oras ng kontak sa lupa, at ibabalik ng calculator na ito ang iyong RSI — ang taas ng talon na hinati sa oras ng kontak — kasama ang isang banda ng marka. Gamitin ito upang subaybayan ang plyometric training, pamahalaan ang neuromuscular fatigue, at ihambing ang reaktibong kakayahan sa pagitan ng mga atleta.

Sinusukat ng Reactive Strength Index (RSI) kung gaano mo kahusay natitiis at nagagamit muli ang impact: ang taas ng talon na hinati sa oras ng kontak sa lupa, mula sa isang drop jump. Ang mas mataas na RSI ay nangangahulugan ng mas pasabog at mas malantik na stretch-shortening cycle. Karaniwang gabay na halaga: mababa sa 0.5 ay mababa, mga 1.0 ay karaniwan, 1.5–2.5 ay mahusay, mahigit 2.5 ay elite. Sukatin ang oras ng kontak gamit ang jump mat o force plate at panatilihing pareho ang taas ng pagbagsak upang masubaybayan ang pagbabago.
