Effects of different doses of high-speed resistance training on physical performance and quality of life in older women: a randomized controlled trial

Abstract

ObjectiveThis study aimed to compare the effects of two frequencies of high-speed resistance training (HSRT) on physical performance and quality of life of older women.MethodsA total of 24 older women participated in a 12-week HSRT program composed of either two or three sessions/week (equated for volume and intensity). Women were randomized into three arms: a control group (CG, n=8), a resistance training group performing two sessions/week (RT2, n=8), and a resistance training group performing three sessions/week (RT3, n=8). The training program for both experimental groups included exercises that required high-speed concentric muscle actions.ResultsNo baseline differences were observed among groups. Compared with the CG, both training groups showed similar small to moderate improvements (P<0.05) in muscle strength, power, functional performance, balance, and quality of life.ConclusionThese results suggest that equated for volume and intensity, two and three training sessions/week of HSRT are equally effective for improving physical performance and quality of life of older women.

Relationship between strength and muscle mass in middle-aged and elderly women: a cross-sectional study

“…The main consequences of the loss of strength that occurs with advancing age are physical limitations, the mobility deficit and incapacity, which increase the risk of falls, fractures, hospitalizations, dependency, fragility and mortality 32,5 .…”

“…Almeida & Greguol 7 suggest that there is a decrease in muscle mass of approximately 2.5% per decade, which can lead to changes in balance, proprioception and the ability to walk, resulting in a higher risk of falls, bed restrictions and increased functional dependence 5 .…”

Quality of life and physical activity among younger working age Wroclaw residents

“…Positive relationships between the overall quality of life and the volume of performed physical activity were also observed by anokye et al [28], Brodáni et al [29], rosenkranz et al [30] and Kolt et al [31]. in the studies by ramirez-campillo et al [32], individuals with a high level of physical activity were characterized by higher self-assessment of quality of life as compared with the control group with significantly lower physical activity.…”

“…the wroclaw residents who undertook high-intensity physical effort probably did it as part of organized physical activities. the beneficial effects of physical activity associated with exercise on the quality of life has already been documented in literature [32].…”

“…the results presented in this paper also remain in line with earlier papers analyzing the relationships between particular areas of the quality of life and physical activity. For example, a higher self-assessment of the quality of life in the somatic domain among more physically active people was noted by Krzepota et al [18] and ramirez-campillo et al [32]. chai et al [23] observed positive relationships between quality of life in the psychological domain and the level of physical activity.…”
