WebThe RSI is most typically used on a 14-day timeframe, measured on a scale from 0 to 100, with high and low levels marked at 70 and 30, respectively. Short or longer timeframes are used for alternately shorter or longer outlooks. High and low levels—80 and 20, or 90 and 10—occur less frequently but indicate stronger momentum. WebThe drop jump, also called the depth jump or box jump, is a fitness test of leg strength and power which requires the athlete to "drop off" a box and immediately jump as high as they can.
