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 40 mm , while nonathletes' stretch only 33 mm . the spring constant for the tendon is the same for both groups, 31 {\rm {n}/{mm}} . what is the difference in maximum stored energy between the sprinters and the nonathletes?

Difference in maximum stored energy

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
