Review constants I Porodic Table The elastic energy stored in your tendons can contribute up to 35 % of your energy needs when running. Sports scientists have studied the change in length of the knee extensor tendon in sprinters and nonathletes. They find (on average) that the sprinters' tendons stretch 42 mm, while nonathletes' stretch only 33 mm Part A The spring constant for the tendon is the same for both groups,...

1. Sports scientists find that, on average, the knee extensor tendons in sprinters stretch by 44 mm, while those of non-athletes stretch only by 32 mm. The spring constant is the same for both groups, 33 N/mm. a) How much more energy do those sprinters store than the rest of us at full extension (2 s.f.)? b) If the efficiency of energy storage of the sprinters' tendons is about 93%, how much kinetic energy does the sprinter recover from a...

The elastic energy stored in your tendons can contribute up to 35% of your energy need when running. During a race, sprinters will use shoes with nearly no padding because their body returns more energy without it. Find the energy stored in an athlete's quadriceps tendon with length 42.0 mm and diameter 8.00 mm when the tendon is strained by 11%. The Young's modulus of the tendon is 236 MPa.
