Motor Coordination/ Agility Testing at Middle-Age and Old-Age.

<p><b>A. Middle-aged Male Ames Dwarf Mice</b>. An additive effect of Ames Dwarfism and caloric restriction is observed during testing of motor coordination and agility in middle-aged males….. <b>B. Middle-aged Female Ames Dwarf Mice</b>. …..and the same results are observed for middle-aged females. <b>C. Old Male Ames Dwarf Mice</b>. <b>D. Old Female Ames Dwarf Mice</b>. Perfect performance is observed in old Ames Dwarf females on CR during testing of motor coordination and agility. (The red horizontal bars at neuromusculoskeletal scores of 1 demark perfect performance.) All measures of central tendency are arithmetic means, and all depictions of variation (error bars) represent standard deviations (S.D.).
