To ­assess age and ­gender dif­fer­ences in ­muscle ­strength and func­tional per­for­mance, max­imal vol­un­tary con­trac­tion (­trunk exten­sion/­flexion, hand­grip), Phys­ical Per­for­mance ­Test (PPT), ­dynamic bal­ance, ­dynamic ­muscle ­strength, ­body com­po­si­tion ­have ­been per­formed by 13 ­healthy and phys­i­cally ­active eld­erly (6 ­women and 7 men) ­aged 69-78 ­years. Cor­re­la­tion anal­ysis ­revealed sig­nif­i­cant (p<0.05) rela­tion of all ­muscle ­strength ­data ­with ­Free Fat ­Mass (FFM) and ­Total ­Body ­Water (TBW). Cor­re­la­tion ­between bal­ance and PPT ­score, ­walking ­speed and age was ­also ­found. Dif­fer­ently ­from ­other ­studies no fur­ther cor­re­la­tion was ­found ­between PPT ­score and ­other var­i­ables. A ­Student’s ­impaired t-­test was ­used to eval­uate if the dif­fer­ences ­between two ­groups was sig­nif­i­cant. PPT ­score was ­high ­both in men (22.1) and ­women (23.5), ­according ­with ­their inde­pen­dent life­style. ­Body com­po­si­tion was sig­nif­i­cant dif­ferent (p<0.05) ­between ­gender. TBW per­centage was nor­mally in men (54.3%) but ­slightly ­lower in ­women (46.3%). As ­regards abso­lute ­strength men was more pow­erful (p<0.05) ­than ­women in all ­tests, but rel­a­tive ­strength (N/kg of FFM) was sim­ilar for ­both ­groups ­showing ­that ­women ­were as fit as men. ­From ­this ­study it ­appears ­clear how an ­active life­style ­matched ­with a phys­ical ­activity pro­gram can main­tain or ­improve a fit­ness ­level in eld­erly ­people. ­This ­enables old ­people to ­live inde­pen­dently and ­improve ­their ­quality of ­life post­poning and ­slowing sev­eral dis­eases or inju­ries due to the ­aging pro­cess.
