After doing specific training for 12 weeks, people over the age of 90 improved their strength, power and muscle mass. This was reflected in an increase in their walking speed, a greater capacity to get out of their chairs, an improvement in their balance, a significant reduction in the incidence of falls and a significant improvement in muscle power and mass in the lower limbs. These are some of the outcomes of the study recently published in the journal Age of the American Aging Association and which was led by Mikel Izquierdo-Redín, Professor of Physiotherapy at the NUP/UPNA-Public University of Navarre.
24 people between 91 and 96 participated in the research, eleven of them in the experimental group and 13 in the control group. Two days a week over a 12-week period they did multicomponent training: a programme of various exercises designed specifically for them and which combined strength training and balance improving exercises. As Mikel Izquierdo explained, "the training raised their functional capacity, lowered the risk of falls, and improved muscle power. In addition to the significant increases in the physical capacity of frail elderly people, the study has shown that power training can be perfectly applied to the elderly with frailty."
With aging, the functional capacity of the neuromuscular, cardiovascular and respiratory system progressively starts to diminish, and this leads to an increased risk of frailty. Physical inactivity is one of the fundamental factors that contributes to the loss of muscular mass and functional capacity, a key aspect in frailty.
"From a practical point of view," says Prof Izquierdo, "the results of the study point to the importance of implementing exercise programmes in patients of this type, exercises to develop muscle power, balance and walking." In his view, "it would be beneficial to apply exercises of this type among vulnerable elderly people to prevent the impact of aging, improve their wellbeing and help them to adapt to the society in which they live."
The piece of research which has been echoed by the American Aging Association is entitled: "Multicomponent exercices including muscle power training enhance muscle mass, power output and functional outcomes in instituzionalized frail nonagenarians."
