Is Stair Climb Power a Clinically Relevant Measure of Leg Power Impairments in At-Risk Older Adults?

Efetividade do treinamento de resistência à fadiga dos músculos dos membros inferiores dentro e fora d'água no equilíbrio estático e dinâmico de idosos

“…In the present study, we observed that the groups that underwent the muscle endurance test improved their mean score on this scale. Similar data, in which it was observed that training and balance programs improve the scores on this scale, are found in the literature 11,14,[30][31][32] . In the experiment conducted by Hess and Woollacott 33 , a muscle endurance program lasting only ten weeks provided an improvement in older adults' balance that was made evident by significantly higher scores on the Berg Balance Scale.…”

“…Likewise, other studies had shown that muscle training has a positive impact on balance among older adults 8,9,11,13,18 . Our training protocol had a frequency of twice a week, for a period of six straight weeks.…”

“…Aquatic exercises make it possible to create situations of instability by using effects such as turbulence, providing a great amount of sensory information, which in turn promotes improvement in body balance reactions 14,15,[17][18][19][20] . On the other hand, exercises performed in a non-aquatic environment are closer to activities of daily living activities, since they do not cancel out the force of gravity [9][10][11][12][13] . However, there are no studies in the literature comparing the effectiveness of muscle endurance training in aquatic and non-aquatic environments.…”

“…Most studies in the literature have shown improvements in older patients' balance through multifactorial interventions, including balance 10,11 , muscle endurance 9,11 or muscle strengthening [11][12][13] exercises, or an association between these [8][9][10] . Studies that assess the effect of muscle endurance training alone on balance are rare 9,11 .…”

“…Muscle endurance exercises may be carried out in an aquatic environment, as well as on the floor [9][10][11] . Aquatic exercises make it possible to create situations of instability by using effects such as turbulence, providing a great amount of sensory information, which in turn promotes improvement in body balance reactions 14,15,[17][18][19][20] .…”
