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.

Effects of 8-Week Whole-Body Vibration Training on the HbA1c, Quality of Life, Physical Fitness, Body Composition and Foot Health Status in People with T2DM: A Double-Blinded Randomized Controlled Trial

“…The effects of WBV training on quality of life and foot health in people with T2DM have been poorly studied. Regarding quality of life, previous studies showed that WBV could improve the quality of life in older populations [45] and other chronic conditions [46,47]. In this regard, a previous study of 6 weeks of WBV improved all domains (pain, general and mental health, vitality, physical, emotional, and social functioning) of the SF-36 quality of life questionnaire in people with diabetic neuropathy.…”

“…All of them, in some way, interfere with or affect the development or perception of quality of life and subjective wellbeing of older seniors. Among them, it is possible to mention: VO 2 max (Sillanpää et al, 2012), functional capacity (Wanderley et al, 2013), self-motivation (Solberg et al, 2014), restricted feeding practices (diets) and reduction of body weight (Napoli et al, 2014), social interaction (Fisken et al, 2015;Sales et al, 2015), food supplementation and type of questionnaire (Trabal et al, 2015), place of exercises (Sales et al, 2015), frequency (Santin-Medeiros et al, 2017), intensity (Santin-Medeiros et al, 2017), muscle strength (Haraldstad et al, 2017;Ni et al, 2016), and muscle mass (Haraldstad et al, 2017). Such variables should be studied in further research with older seniors, in order to expand the results identified so far.…”

“…Taking into account the increase of life expectancy, researchers have been interested in studying the quality of life of the third age range, focusing on preserving and promoting the health and the well-being of this portion of the population so that they have a healthy aging (Fisken et al, 2015;Rachadel et al, 2015;Santin-Medeiros et al, 2017). According to the World Health Organization Quality of Life Group (WHOQOL, 1995), quality of life is the perception of individuals about their position in life combined with their sociocultural context and their objectives, expectancies, standards and concerns.…”

“…According to the World Health Organization Quality of Life Group (WHOQOL, 1995), quality of life is the perception of individuals about their position in life combined with their sociocultural context and their objectives, expectancies, standards and concerns. Many authors evaluate the quality of life in seniors and they all agree that, as years pass by, the quality of life is affected due to the changes that occur during the aging process (Fisken et al, 2015;Rachadel et al, 2015;Santin-Medeiros et al, 2017). It believed that a better quality of life is closely associated with a subjective well-being that, according to Diener, Oishi and Lucas (2003), is related to one's evaluation of one's own experiences with positive affections of happiness, joy, and life satisfaction.…”

“…Authors' elaboration following PRISMA methodology. Among the analyzed studies, there was a great diversity of physical exercises that are practiced by elderly people: yoga(Ni, Mooney, & Signoreli, 2016), tai chi chuan(Wayne et al, 2013(Wayne et al, ), walking (Émile et al, 2014 Horder et al, 2013), whole-body vibration training(Santin-Medeiros et al, 2017), strength training (Haraldstad et al, 2017), resistance training…”
