反应力量指数计算器
反应力量指数是跳跃和短跑运动员衡量爆发性、反应性力量的常用现场测试。输入你的落地跳高度和触地时间，本计算器会返回你的 RSI——跳跃高度除以触地时间——以及对应的评级区间。可用它监控增强式训练、管理神经肌肉疲劳，并比较运动员之间的反应能力。
反应力量指数（RSI）衡量你承受并再利用冲击的能力：在落地跳中，用跳跃高度除以触地时间。RSI 越高，说明拉长–缩短周期越爆发、越富有弹性。常见参考值：低于 0.5 偏低，1.0 左右为平均，1.5–2.5 为良好，高于 2.5 为精英水平。用跳垫或测力台测量触地时间，并保持落下高度一致以便追踪变化。
常见问题
- 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.
