“…On the other hand, a study (Puthoff et al, 2008) of elderly people with minor disabilities demonstrated that both the steps/day and the total walking distance per day were significantly related to leg strength or power. Although the study included elderly men and made no reference to the intensity of the AA, the findings suggested that people with more daily AA had stronger leg strength.…”

The effect of daily ambulatory activity on physical fitness has not yet been identified by quantitatively measuring the time spent on the intensity levels of ambulatory activity in elderly women over 75 with different functional capacity levels. The subjects consisted of 147 elderly women over 75 years old (82.8Ϯ4.3 years old) who were all capable of performing basic daily activities by themselves. Physical fitness was measured for 7 items (handgrip strength, knee extensor strength, postural stability, stepping, one-legged standing time with eyes open, 10 m walking, and the Timed Up and Go Test). The subjects wore a triaxial accelerometer for 2 consecutive weeks to measure their daily physical activities. The functional capacity level was assessed by the Tokyo Metropolitan Institute of Gerontology Index of Competence. The subjects were divided into two groups, a group with a score Ն10 points (high functional capacity group, nϭ59) and a score Ͻ10 points (low functional capacity group, nϭ88), and the relationship between physical fitness and physical activity was examined in both groups. In both the high and low functional capacity groups, 10 m walking, the Timed Up and Go Test, and one-legged standing time with eyes open significantly correlated with either the total steps/day or the ambulatory activity intensity. In the high functional capacity group, the knee extensor strength also significantly correlated with the total steps/day and moderate ambulatory activity. It is suggested that very elderly women with a reduced functional capacity should maintain their mobility by simply increasing their daily ambulatory activity.

“…Age-associated decline of muscle strength has usually been depicted as linear or curvilinear, with acceleration after the fifth decade [11]. The role of muscle strength in maintaining independence in daily functioning has been widely evidenced in research, especially in patients with limited mobility [12,13]. The most important muscle group necessary to maintain independence in the activities of daily living are the muscles of the lower limbs [14].…”

“…Decreased quadriceps muscle υ opt and P max may cause gradually impaired functioning, and due to this impairment, many elderly subjects are approaching or reaching their functional threshold. In studies comparing the relationships of strength and muscle power to functional capacity, muscle power almost always appears to be a stronger determinant [3,13,23]. In elderly people, maximal muscle power is responsible to a greater extent for the variability of the results in functional tests than muscle strength, especially during low-intensity tasks such as walking [24].…”

“…In fact, it has been reported a positive correlation between muscle strength and VPA, as well as a positive correlation between muscle strength and IPA 3,[8][9][10] . However, the methods used by these studies 3,[8][9][10] prevents a more assertive conclusion about the in uence of muscular strength in VPA and IPA. For example, the use of questionnaires, though validated, do not allow precise quanti cation of the VPA and the IPA.…”

Resumo Diminuições no volume da atividade física diária (VAF - número de passos) e na intensidade da atividade física diária (IAF – velocidade média de caminhada) estão relacionadas com a maior incidência de quedas e aumento da incidência de doenças crônico-degenerativas em idosos. Portanto, identificar fatores que possam aumentar o VAF e a IAF torna-se essencial, principalmente para essa população. Desta forma, o objetivo do presente estudo foi investigar a influência da força muscular no VAF e na IAF de idosos saudáveis. Foram recrutados 18 participantes (10 homens e oito mulheres), com idade acima de 60 anos. Os participantes realizaram o teste de uma repetição máxima (1-RM) e utilizaram acelerômetro triaxial durante sete dias consecutivos, para mensurar o VAF e a IAF. Para analisar a influência da força no VAF e IAF realizou-se uma análise de regressão linear simples. Não foram observadas correlações significantes entre a força muscular e o VAF (p = 0,93; r2 = −0,06), assim como, entre a força muscular e a IAF (p = 0,08; r2 = 0,17). Conclui-se que a força muscular não influencia o VAF e a IAF de idosos saudáveis.
