Calculate the reactive force and reactive muscle moment at Justin Verlander’s knee for a seated leg extension, with a weight of 55, 75, and 95 lbs. Assume that the leg is held at an angle ??, and if it were fully extended, then ??=0. Assume that the load is applied in a way such that it remains perpendicular to the lower leg. Justin Verlander is 1.96 meters tall and has a mass of 102 kg. (Note the units!) a. State ALL of your assumptions. b. Calculate the force and reactive muscle moments in terms of ??. c. Solve for the force and reactive moments for each load at ?? = 90̊, 60̊, 30̊, 0̊.

What is happening inside of the leg muscle cells of a runner during a 100-meter dash compared to a 2-mile race? What biochemical pathway(s) (aerobic respiration or anaerobic respiration) is/are being utilized in each race, and why? Explain why photosynthetic organisms are considered the ultimate source of food. What would happen to humans if all the plants died? ReplyForward

During strenuous activity, the demand for ATP in muscle tissue is vastly increased. In rabbit leg muscle or turkey flight muscle, the ATP is produced almost exclusively by lactic acid fermentation. ATP is formed in the payoff phase of glycolysis by two reactions, promoted by phosphoglycerate kinase and pyruvate kinase. Suppose skeletal muscle were devoid of lactate dehydrogenase. Could it carry out strenuous physical activity; that is, could it generate ATP at a high rate by glycolysis? Explain. Discuss the...

Before heading to the Tour de France a cyclist had a muscle biopsy in his leg. The tests revealed that the dominant muscle fibers were low in myosin ATPase activity and anaerobic enzymes, high in capillary density and myoglobin content. For this athlete to maintain force production, what direct change (in the cytosol) in ion concentration must occur?

Determine the reactions at the support of the beam. Shear force and bending moment for the beam are described by V(x)= c0 + c1x + c2x2 and M(x)= k0 + k1x + k2x2 + k3x3, respectively. Calculate the coefficients for the shear force and bending moment equations. Use L = 5.8 m, q = 2.7 N/m, and w = 8.6 N/m for your calculation. Also, determine Vertical reaction force at A in N (upwards force is positive, round your result...
