The SCORE evaluation is based in part on linear power, which is measured by the athlete's performance on the Sanford SCORE single-leg triple jump test. The athlete will be standing on one leg and making three forward cross-over jumps as quickly as possible. The athlete needs to jump as far and as fast as he or she can. To complete this drill, you will need someone to keep time and measure, a stop watch, floor tape, and a measuring tape (about 30 ft).

Instructions

  1. SetUp

    First, determine a starting line. Next, position the measuring tape on the floor beginning at the starting line and extend it in a straight line for about 25 feet, forming a "T" with the starting line. Anchor the measuring tape to the floor with floor tape. Have the person who will time you stand with a stopwatch about 15 feet away.

  2. Test & Measure

    To begin, the athlete starts in an upright, standing position behind the starting line and balances on either the left or right foot (you can start with either leg, but the athlete will need to repeat the drill with the opposite leg)). To begin with the left leg, the athlete stands just to the left of the measuring tape. For the right, the athlete stands to the right of the measuring tape. Be sure the athlete's toes are behind the starting line.

    To perform the drill, the athlete balances on one foot and jumps forward three times as quickly as possible, each time crossing over the measuring tape (like a forward zigzag). On the first two jumps, the athlete lands on his or her jumping leg. On the last jump, the athlete sticks the landing with both feet and remains in position while the distance is measured.

    • The athlete will have two attempts for each leg.
    • If the athlete touches the tape with his or her foot, the jump is not counted.

    To measure, start the stopwatch as soon as the athlete moves. Stop the timer when the athlete lands the third jump. Round the time to the nearest hundredth of a second. Record the time. Then, measure the jump distance from the starting line to the back of the athlete's heel that is closest to the starting line. Record this measurement in feet and inches, rounding to the nearest inch.

  3. Calculate & Record

    Record the jump distance in feet and inches, rounding to the nearest inch. Then record the time, rounding to the nearest hundredth of a second. When the athlete has completed the drill (two attempts allowed for each leg), calculate the velocity for each attempt. To calculate velocity, convert the distance jumped to inches by multiplying the number of feet by 12 and then add the remaining inches to the total. Next, divide the distance in inches by the number of total seconds, and round the number to two decimal places. This calculates inches/second.

    • Calculate total distance in inches: (feet x 12) + inches. For example 9 feet x 12 = 108 inches + 7 inches for a total of 115 inches.
    • Divide distance by time (115 inches/3.14 seconds = 36.62 inches/sec).
    • Record: 36.62 inches/sec.
    • Calculate each attempt. The fastest velocity of each leg will be used for the athlete's SCORE.
