Document Summary

Exss1029 muscle mechanics and training: whole muscles. 6. 1 interpret muscle mass in terms of myosin content. Discuss, in general terms, the advantages and disadvantages of large total muscle mass in terms of survival in a prehistoric environment. Each gram of muscle contains around 1 x 1017 molecules of myosin. Differences between heavy and light muscles directly indicate the total myosin content of muscles. Tension between striking the right balance between making muscles large enough so they can carry out their function but not too large that their weight will become a burden. Altering values of muscle (33kg male and 21kg female) substantially alters the energy required to lift and support he body against gravity thus changing energy costs of all forms of locomotion. Adult size of human muscles is preprogramed. Sufficient enough to accomplish key motor activities. Not unnecessarily large so that carry extra kg of muscle increases the chances of starvation due to excessive energy loss.
