Abstract
BackgroundAging may cause various functional abilities gradually deteriorate. With changes in social forms, the trend of functional fitness decline will change accordingly. Therefore, this study endeavored to identify the trends in functional fitness decline by comparing the differences in the functional fitness of females in various age groups.MethodsThirty six healthy females were divided into 3 age groups: young healthy females (20 to 30 y); middle-age (45 to 55 y); and older (65 to 75 y). Functional fitness test battery included flexibility, muscle strength/endurance, aerobic endurance, balance and agility.ResultsThe performance in the elderly group was significantly worse (P < .05) in all the tests, whereas the muscle strength and endurance, as well as aerobic endurance for the middle-age group showed significantly lower than young groups (P < .05).ConclusionsThe reduction in lower extremity muscle strength occurs in the middle-age group. We recommend that middle-age women be conscious of the reduction in their lower extremity muscle strength and conduct advanced preparations for future aging.

Aging may cause various functional abilities gradually deteriorate
Previous studies have indicated that after 40 years of age, muscle strength decreases annually by an average of 1 %; after 60 years of age, the extent of reduction becomes more substantial; between 60 and 70 years of age, muscle strength decreases by approximately 15 %; and, compared to young people, the muscle mass of elderly people above 65 years of age and above 80 years of age decreases by approximately 9 % to 18 %, and 30 %, respectively [3]
The results indicated that various abilities had already begun deteriorating in middle-age people, and no significant differences in these abilities were identified between middle-age and elderly people
Summary
Aging may cause various functional abilities gradually deteriorate. This study endeavored to identify the trends in functional fitness decline by comparing the differences in the functional fitness of females in various age groups. Various bodily abilities gradually deteriorate with time. Both muscle mass and muscle function decrease as people age, which causes muscle strength to decline. This phenomenon is known as sarcopenia [9, 10]. Sarcopenia poses serious health threats to elderly people, with the most obvious
