What's the benefit of a long tendon and short muscle belly in the forearm? If your distal tendon of the bicep is so short that you can't see where the muscle ends and the tendon begins, and you flex your elbow joint, the contracted bicep will get in the way of making a very small angle. If the tendon's longer, even though flexing the elbow joint contracts the bicep, the angle's a lot smaller before the forearm comes in contact with the bicep, thereby preventing further flexion. |

Is it safe to do jogging on asphalt? Yes, the slower you go the less a heelstrike becomes a problem, although I would suspect it isn't necessarily speed and more the length of the stride. If your leg is far ahead of you for a heel strike the moment arm from the heel to knee and from the knee to hip is quite a bit longer than if you're heel striking with your foot just barely out in front of you. |
