Abstract

Aim The present study investigated the acute effects of low- and high-speed resistance exercise on the cognitive function of frail older women living in nursing home. Materials and Methods Ten institutionalized frail older women were recruited. Rey Auditory Verbal Learning Test and Stroop test were performed before, immediately after, 1 h after, and 24 h after the end of the experimental session. Participants randomly performed low- and high-speed resistance exercise and a control session. Exercise sessions were composed of 4 resistance exercises with 4–8 sets of 4–10 repetitions at moderate intensity. Results Results indicated that the performance of Rey Auditory Verbal Learning Test was similarly increased immediately after both low- and high-speed resistance exercises. However, only improvements elicited by low-speed resistance exercise remained significant 1 h after the end of the exercise session. No acute effects of resistance exercise were observed on Stroop performance. Conclusion Our findings indicated that both low- and high-speed resistance exercises acutely increased episodic memory in frail older women, whereas no changes on Stroop were observed.

Highlights

Frailty refers to a reversible state of increased vulnerability to stressful agents, which occurs as a result of multisystem derangements and poor social support [1]. e progression of frailty is marked by increased occurrence of negative events, such as falls and fractures, disability, and loss of independence [1]
Discussion e findings of the present study indicate that, in frail older women living in nursing home, both low-speed resistance exercise (LSRE) and high-speed resistance exercise (HSRE) acutely increased Verbal learning (VL), an indicator of episodic memory
Findings were obtained in frail older women living in nursing home and may not be generalized to noninstitutionalized robust older adults or to the male gender

Summary

Introduction

Frailty refers to a reversible state of increased vulnerability to stressful agents, which occurs as a result of multisystem derangements and poor social support [1]. E progression of frailty is marked by increased occurrence of negative events, such as falls and fractures, disability, and loss of independence [1]. A significant association between frailty and cognitive decline has been documented [2,3,4,5,6,7]
