Musculoskeletal Dynamics Grant Schaffner

1. In shortening, the relationship between the Force and Velocity is (Hill's Curve - know this!!): (T+a)(v+b) = (T0+a)b Hyperbolic Form

Muscles Active while Lengthening Consider the example of ordinary exercise, lets say one of the running events in the Olympics. Muscle functions to stop the motion of the athlete as often as it does to start it. When a load larger than isometric tetanus tension To is applied to a muscle in a tetanic state of activation, the muscle lengthens at a constant

Skeletal Consequences of Spaceflight Background Early flights: very little idea of physiological changes to expect -big concerns: respiration, cardiovascular -bone probably wasn't a serious consideration What has been learned in the past 37 years of human spaceflight?
