“…Reduced muscle strength has tremendous potential implications on the ability of these frail elderly to perform activities of daily living necessary to maintain their independence in the community (Hyatt et al, 1990;Bassey et al, 1992). Interestingly, in our study with a very homogeneous population, the low FFM was not related to the Timed`Up & Go' test measuring a combination of balance, gait speed and physical mobility, and correlating strongly with all aspects of perceived function.…”

“…Previously reported correlations of FFM and muscle strength have often been confounded by gender, as males have both a higher percentage of FFM and greater muscle strength than women (Frontera et al, 1991;Reed et al, 1991;Hyatt et al, 1990). Although one can improve muscle strength through muscle training in well nourished elderly without weight gain nor change in FFM (Fiatarone et al, 1994), it is important to recognize that many frail elderly have reduced FFM and, associated with this loss, they have incurred a substantially reduced muscle strength.…”

“…Among healthy elderly, muscle area is weakly correlated with muscle strength, once the confounding effect of gender is removed (Frontera et al, 1991;Reed et al, 1991), and losses in muscle mass have been related to losses in muscle function in a number of settings (Hyatt et al, 1990;Skelton et al, 1994). To date most data on body composition in the elderly have been gathered among healthy volunteers who, because of their interest in being measured, may represent a particularly healthy subset of the population.…”

Objectives: (1) To describe body composition of the frail elderly, (2) To relate lean body mass to muscle strength and functional ability, and (3) To assess temporal stability of strength measures and index of functional ability. Design: Cross-sectional study. Setting: Community-dwelling. Subjects: Thirty frail elderly women (81.5 AE 7 y) recruited from residences or out-patient facilities. Methods: Total body fat and fat-free mass (FFM) were determined using multi-frequency bioelectrical impedance analysis and predicted from anthropometry. Handgrip strength, biceps and quadriceps strength, functional capacities (Timed`Up & Go') as well as self-perceived health and functional status were measured. Reliability was assessed using two separate observations made one week apart by the same examiner. Results: Mean height, weight and body mass index were 1.52 AE 0.04 m, 60.4 AE 10.7 kg and 26.0 AE 4.8 kg/m 2 respectively. FFM (34.1 AE 4.6 kg) was lower than previous reports for autonomous elderly females and associated with all measures of muscle strength (Pearson's r 0.42±0.62, P 0.02), but not with performance on the Timed`Up & Go' or self-perceived health and functional status. Strength measures correlated signi®cantly with different subscales of self-perceived functional capacities and were signi®cantly lower among women with a low %FFM (n 19) and those reporting pain (n 11) as compared to other women. Excellent temporal stability for muscle and functional measures was observed (ICC 0.80±0.90). Conclusions: Muscle strength was strongly related to FFM in free-living frail elderly women especially in the absence of pain.

“…La medición de la fuerza muscular y su correlación con el estado funcional y la capacidad de coordinación neuro-motriz ha sido ampliamente estudiada y se han encontrado altas correlaciones en las escalas de función e independencia cuando se compara la fuerza de prensión y el estado funcional de las extremidades mediante dinamometría (Hyatt, 1990); por otra parte, aunque se ha encontrado que la relación de la fuerza isométrica comparada en las dos extremidades es poco relevante, es cierto que se han encontrado diferencias, para el caso de las manos de hasta 10%, en favor del lado dominante, y consideradas como normales (Miranda, 2007). No obstante, en este estudio se ha encontrado para las personas mayores, que existe una diferencia significativa, expresada en déficit de la mano contralateral a la dominante en quienes practican actividad física, lo cual podría traducirse como una mayor utilización de las manos derecha y/o izquierda asociadas a ejercicio físico practicado con mayor frecuencia e intensidad.…”

RESUMENLa práctica sistemática de actividad física contribuye al mejoramiento de las condiciones de vida y salud y retarda el proceso de envejecimiento del adulto mayor. Objetivo. Identificar diferencias en la autonomía funcional en hombres de 60 a 70 años, practicantes de ciclismo y sedentarios, residentes en Tunja, a altitud moderada. Materiales y Métodos. Estudio comparativo de corte transversal analítico. Participaron 22 adultos mayores, de sexo masculino; 11 sedentarios y 11 practicantes de ciclo montañismo, con edades entre 60 y 70 años (media 63.03±4.32 años) previo consentimiento informado se sometieron a evaluación cineantropomé-trica por bioimpedancia, las pruebas de la batería Senior Fitness Test (SFT) de Rikli y Jones (1999a) el Test de Ästrand submaximal y dinamometría manual derecha e izquierda. Resultados: Los grupos se encontraron comparables en edad, peso, talla e índice de masa corporal (p>0,05). Se registraron diferencias estadística-mente significativas a favor del grupo de ciclo montañistas, en la media del porcentaje de grasa corporal, densidad ósea, masa muscular, mientras que ni el índice de masa corporal (25,6 ±3,3 y 25,2±2,5) registraron diferencias significativas. En la prueba SFT se encontraron diferencias estadísticamente significativas en la flexión de cadera (p<0,001). En la prueba submaximal se encontraron diferencias estadísticamente significativas en la prueba de esfuerzo en Watts (p=0,021). En la dinamometría de la mano izquierda también se encontraron diferencias estadísticamente significativas (p=0,0007). Conclusión. Los adultos mayores que adelantan rutinariamente prácticas de ejercicio físico como el ciclo montañismo presentan mejores características de composición corporal, flexibilidad de la cintura, mejor capacidad aeróbica y motricidad.Palabras claves: actividades físicas, adulto mayor, autonomía personal SUMMARYThe systematic practice of physical activity contributes to improve living and health conditions and slows dawn the aging process in seniors. Objective. Identify differences in functional autonomy in 60-70 year old mountain cyclists and sedentary males residing in Tunja, at moderate height. Materials and Methods. Comparative analytical cross-sectional study. A total of 22 elderly males participated; 11 sedentary seniors and 11 mountain cyclists, ages between 60 and 70 (mean 63.03 ± 4.32 years).

“…Using muscle strength to define sarcopenia has several limitations. To generate strength, other factors such as cardiovascular function, joint function, and neural control are involved (McCully and Posner 1995;Karttunen et al 2011;Hyatt et al 1990). Furthermore, muscle strength can be underestimated due to pain (Lauretani et al 2003;Rolland et al 2008).…”

Relative and absolute muscle mass and muscle strength are used as diagnostic criteria for sarcopenia. We aimed to assess which diagnostic criteria are most associated with physical performance in 180 young (18-30 years) and 281 healthy old participants (69-81 years) of the European study MYOAGE. Diagnostic criteria included relative muscle mass (total or appendicular lean mass (ALM) as percentage of body mass), absolute muscle mass (ALM/height squared and total lean mass), knee extension torque, and handgrip strength. Physical performance comprised walking speed, Timed Up and Go test (TUG), and in a subgroup physical fitness. Diagnostic criteria for sarcopenia and physical performance were standardized, and the associations were analyzed using linear regression models stratified by age category, with adjustments for age, gender, and country. In old participants, relative muscle mass was associated with faster walking speed, faster TUG, and higher physical fitness (all p<0.001). Absolute muscle mass was not associated with physical AGE (2014) performance. Knee extension torque and handgrip strength were associated with faster walking speed (both p≤0.003). Knee extension torque was associated with TUG (p=0.001). Knee extension torque and handgrip strength were not associated with physical fitness. In young participants, there were no significant associations between diagnostic criteria for sarcopenia and physical performance, except for a positive association between relative muscle mass and physical fitness (p<0.001). Relative muscle mass, defined as lean mass or ALM percentage, was most associated with physical performance. Absolute muscle mass including ALM/height squared was not associated with physical performance. This should be accounted for when defining sarcopenia.
