Changes in Postural Balance in Frail Elderly Women during a 4-Week Visual Feedback Training: A Randomized Controlled Trial
2002
<i>Background:</i> Balance training programs have not shown consistent results among older adults, and it remains unclear how different training methods can be adapted to frail elderly people. <i>Objective: </i>The purpose of this study was to investigate the effects of a 4-week visual feedback-based balance training on the postural control of frail elderly women living in residential care homes. <i>Methods:</i> Elderly women of two residential care facilities were randomized to an exercise group (EG, n = 20) and to a control group (CG, n = 7). The EG participated in training sessions three times/week for 4 weeks. The exercises were carried out with a com…
Electrocardiographic and other clinical correlates of walking ability in older women
2009
Abstract The purpose of this study was to examine how resting electrocardiographic (ECG) and other clinical variables, which can be included in a routine clinical examination, predict walking ability in older women. Three hundred and twenty women (63–75 years) without overt cardiac diseases and apparent mobility limitations were studied. Measurements performed were clinical examination (standard 12-lead resting ECG, assessment of physical activity level, presence of chronic diseases, use of beta-blockers, body mass index (BMI), ability to squat, resting blood pressure) and six-minute walking test. Participants walked 533 ± 75 m in the six-minute walking test. The best electrocardiographic p…
The value of neutrophil and lymphocyte count in frail older women.
2013
Increasing evidence suggests that systemic inflammation is associated with many pathophysiological processes including frailty in older adults. We evaluated the relationships between white blood cell subtypes, geriatric assessment, and frailty syndrome and in particular, how they correlate with individual frailty criteria (involuntary loss of weight, low energy or exhaustion, slow mobility, muscle weakness, and low physical activity) in frail older women. There was a significant and positive correlation between the frailty score and neutrophil count, but a significantly negative correlation was found when this score was compared to the lymphocyte count. These associations were significant o…
Physical Activity Scaled to Preferred Walking Speed as a Predictor of Walking Difficulty in Older Adults: A 2-Year Follow-up
2021
Abstract Background The usual accelerometry-based measures of physical activity (PA) are dependent on physical performance. We investigated the associations between PA relative to walking performance and the prevalence and incidence of early and advanced walking difficulties compared to generally used measures of PA. Methods Perceived walking difficulty was evaluated in 994 community-dwelling participants at baseline (age 75, 80, or 85 years) and 2 years later over 2 km (early difficulty) and 500 m (advanced difficulty). We used a thigh-mounted accelerometer to assess moderate-to-vigorous PA, daily mean acceleration, and relative PA as movement beyond the intensity of preferred walking spee…
Effects of strength and endurance training on muscle fibrecharacteristics in elderly women
1997
The effects of 18 weeks' intensive strength and endurance training on fibre characteristics of the vastus lateralis muscle were studied in 76- to 78-year-old women. Type I and type IIa fibres constituted over 90% of the cell population and were almost equally represented. No changes were observed in the proportions of the different fibre types. When comparing the baseline and the 18-week measurements within the groups, the strength group showed a mean increase of 34% (P = 0.028) in mean type I fibre area. The frequency histograms showed an increased proportion of larger type I fibres after strength training and a decreased proportion of smaller type IIa fibres after endurance training. In t…
The effect of aquatic exercise on physical functioning in the older adult: a systematic review with meta-analysis
2015
Background ageing and sedentary behaviour cause negative changes in the neuromuscular systems of healthy older adults resulting in a decrease in physical functioning. Exercising in water (aquatic exercise, AE) has been shown to be effective at improving physical functioning in this population; however, no systematic review with meta-analysis has been published. Purpose to investigate the effect of AE on physical functioning in healthy older adults compared to control or land-based exercise (LE) through a systematic review with meta-analysis of randomised controlled trials. Data sources Medline, Embase, Cinahl, PEDro, SPORTDiscus, Web of Science, Cochrane Library, published before 31st Decem…
Improved postural control after dynamic balance training in older overweight women
2010
Background and Aims: Many studies have reported a greater frequency of falls among older women than men under conditions which stress balance. Previously, we have found an improvement in static balance in older women with an increased support surface area and an equal load redistribution on both feet in response to a dynamic balance training protocol. The aim of the present study was to examine whether the same training program and body composition would have effects on the postural control of older overweight women. Methods: Ten healthy women (68.67 ± 5.50 years; 28.17 ± 3.35 BMI) participated in a five-week physical activity program. This included dynamic balance exercises such as heel-to…
Endogenous Hormones, Muscle Strength, and Risk of Fall-Related Fractures in Older Women
2006
Background. Among older people, fracture-causing fall often leads to health deterioration. The role of endogenous hormone status and muscle strength on fall-related fracture risk is unclear. This study investigates if, after adjustment for bone density, endogenous hormones and muscle strength would predict fall-related limb fracture incidence in older community-dwelling women followed-up over 10 years. Methods. As a part of a prospective population-based study, 187 75-year-old women were investigated. Serum estradiol, testosterone, sex hormone binding globulin, and dehydroepiandrosterone sulfate concentrations were analyzed, and isometric muscle strength and bone mineral density were assess…
Effects of strength and endurance training on isometric muscle strength and walking speed in elderly women
1996
The separate effects of 18 weeks of intensive strength and endurance training on isometric knee extension (KE) and flexion (KF) strength and walking speed were studied in 76- to 78- year-old women. Maximal voluntary isometric force for both KE and KF was measured in a sitting position on a custom-made dynamometer chair at a knee angle of 60 degrees from full extension. Maximal walking speed was measured over a distance of 10 m. The endurance-trained women increased KE torque and KE torque/body mass after the first 9 weeks of training when compared with the controls. when comparing the baseline, 9 week and 18 week measurements within the groups separately, both the endurance- and strength-tr…
Combined resistance and balance-jumping exercise reduces older women's injurious falls and fractures: 5-year follow-up study
2014
BACKGROUND AND OBJECTIVE: previously, a randomised controlled exercise intervention study (RCT) showed that combined resistance and balance-jumping training (COMB) improved physical functioning and bone strength. The purpose of this follow-up study was to assess whether this exercise intervention had long-lasting effects in reducing injurious falls and fractures. DESIGN: five-year health-care register-based follow-up study after a 1-year, four-arm RCT. SETTING: community-dwelling older women in Finland. SUBJECTS: one hundred and forty-five of the original 149 RCT participants; women aged 70-78 years at the beginning. METHODS: participants' health-care visits were collected from computerised…
