Effects of Eight Months of Whole-Body Vibration Training on the Muscle Mass and Functional Capacity of Elderly Women.

Abstract Santin-Medeiros, F, Rey-López, JP, Santos-Lozano A, Cristi-Montero, CS, and Garatachea Vallejo, N. Effects of eight months of whole-body vibration training on the muscle mass and functional capacity of elderly women. J Strength Cond Res 29(7): 1863–1869, 2015—Few intervention studies have used whole-body vibration (WBV) training in the elderly, and there is inconclusive evidence about its health benefits. We examined the effect of 8 months of WBV training on muscle mass and functional capacity in elderly women. A total of 37 women (aged 82.4 ± 5.7 years) voluntarily participated in this study. Subjects were randomly assigned to a vibration group (n = 19) or a control group (n = 18). The vibration group trained on a vertical vibration platform twice a week. The control group was requested not to change their habitual lifestyle. The quadriceps femoris muscle cross-sectional area was determined by magnetic resonance imaging. All participants were evaluated by a battery of tests (Senior Fitness Test) to determine their functional capacity, as well as handgrip strength and balance/gait. General linear repeated-measure analysis of variance (group by time) was performed to examine the effect of the intervention on the outcomes variables. After 8 months, nonstatistically significant differences in the quadriceps CSA (pre-training: 8,516.16 ± 1,271.78 mm2 and post-training: 8,671.63 ± 1,389.03 mm2) (p > 0.05) were found in the WBV group (Cohens d: −0.12), whereas the CON group significantly decreased muscle mass (pre-training: 9,756.18 ± 1,420.07 mm2 and post-training: 9,326.82 ± 1,577.53 mm2), with moderate effect size evident (Cohens d: 0.29). In both groups, no changes were observed in the functional capacity, handgrip strength and balance/gait. The WBV training could prevent the loss of quadriceps CSA in elderly women.

Effects of eight months of whole body vibration training on hip bone mass in older women

OBJECTIVE the aim of this study was to examine the effect of 8 months of whole-body vibration training on bone mass in octogenarian women. METHOD Thirty-seven women (aged 82.4 [SD=5.7] years) voluntarily participated in this study. The vibration group (n=19) trained on a vibration platform twice a week (20 Hz and 2 mm) whereas controls (n=18) did not participate in any training program. Bone mass was measured by dual-energy X-ray absorptiometry at the hip region. General linear repeated measures ANOVA (group by time) was used to examine the effect of whole body vibration on bone mass changes. RESULTS After the intervention, in all the hip regions (total hip, femoral neck, trochanter, intertrochanter, Wards area), no statistically significant changes in bone mass were found. CONCLUSION eight months of whole body vibration training (twice a week) in elderly women do not produce osteogenic effects.

Effect of 8 months of whole-body vibration training on quality of life in elderly women

ABSTRACT Whole-body vibration (WBV) training in elderly may improve muscle strength, muscle power and postural control. However, knowledge about the effect of WBV training in elderly on measures of health as a multidimensional construct (health-related quality of life, HRQoL) is scarce. The present study aimed to determine the effects of WBV training on HRQoL in elderly women. A total of 37 women (aged 82.4 ± 5.7 years) were recruited and were assigned to either the WBV group or to the control (CON) group. After 8 months of training, the WBV group showed non-significant changes on HRQoL and additional health-related outcomes (fall risk, life satisfaction or cognitive status). Our findings are in disagreement with previous studies of shorter duration (6 weeks), which reported positive significant changes in HRQoL in elderly people. Discrepancies among studies may be partly attributed to methodological differences, but the existence of publication bias in previous studies cannot be discarded.

Valoración física, condición física y calidad de vida en pacientes con diferentes tratamientos renales sustitutivos

La actividad fisica es de vital importancia en pacientes con enfermedad renal cronica, ya que mejora la capacidad funcional de los sujetos e incrementa notablemente su calidad de vida. Para mejorar la calidad de vida en pacientes con tratamiento renal sustitutivo, dializados o trasplantados, deberian ser incluidos programas de actividad fisica planificados y supervisados por profesionales. Existen varios estudios sobre entrenamiento aerobico y de fuerza en pacientes con enfermedad renal cronica en hemodialisis pero pocos sobre la condicion fisica relacionada con la salud en estos pacientes y escasos los referentes a condicion fisica en trasplantados y en pacientes con dialisis peritoneal. El objetivo principal del estudio fue evaluar el nivel de actividad fisica, condicion fisica y calidad de vida de enfermos renales cronicos con diferentes tratamientos sustitutivos. Material y metodos:25 enfermos renales cronicos varones de entre 59 y 72 anos, que participaron voluntariamente en este estudio, fueron divididos en 3 grupos: trasplantados renales: N=11, hemodializados: N=6, y en tratamiento de dialisis peritoneal: N=8. Se les administro el cuestionario de cuantificacion de actividad fisica YALE, el cuestionario de calidad de vida KDQoL y realizaron la bateria de tests Senior Fitness Test (SFT). Resultados:No se encontraron diferencias significativas entre grupos en ninguno de los cuestionarios ni en los tests realizados. Los 3 grupos mostraron valores inferiores que otras poblaciones sanas de referencia de la misma edad. Conclusiones: El tipo de tratamiento sustitutivo en los pacientes con enfermedad renal cronica no influye sobre el nivel de actividad fisica, condicion fisica ni calidad de vida.
