Nutritional status, physical performance and disability in the elderly of the Peruvian Andes

2016

Background: Although nutritional status plays an important part in the physical performance and disability of older people, this relationship has been little studied in developing countries. Aims: A study on the effects of nutritional status on the physical performance and functional status of elderly people living in rural areas of the Peruvian Andes. Methods: The study concerned 222 people aged ≥65 years living in a rural area of the Peruvian Andes. The Mini-Nutritional Assessment (MNA) was used to classify participants as malnourished (MNA <= 17), at risk of malnutrition (MNA 18-23), or well-nourished (MNA>= 24). The short physical performance battery (SPPB) and six-minute walking …

Mediterranean diet and mobility decline in older persons.

2011

We examined whether adherence to a Mediterranean-style diet has positive effects on mobility assessed over a nine-year follow-up in a representative sample of older adults. This research is part of the InCHIANTI Study, a prospective population-based study of older persons in Tuscany, Italy. The sample for this analysis included 935 women and men aged 65 years and older. Adherence to the Mediterranean diet was assessed at baseline by the standard 10-unit Mediterranean diet score (MDS). Lower extremity function was measured at baseline, and at the 3, 6 and 9-year follow-up visits using the Short Physical Performance Battery (SPPB). At baseline, higher adherence to Mediterranean diet was assoc…

Association between physical performance and sense of autonomy in outdoor activities and life-space mobility in community-dwelling older people

2014

Objectives. To study the relationship between physical performance and sense of autonomy in outdoor activities with life-space mobility—the spatial area a person purposefully moves through in daily life—in community-dwelling older people. Design. Cross-sectional analyses of baseline data of the Life-Space Mobility in Old Age cohort study. Setting. Structured interviews in participants' homes. Participants. Community-dwelling people aged 75 to 90 (N = 848). Measurements. Sense of autonomy outdoors (Impact on Participation and Autonomy questionnaire subscale), life-space mobility (Life-Space Assessment; University of Alabama, Birmingham Study of Aging), and Short Physical Performance Battery.…

Effects of comprehensive geriatric intervention on physical performance among people aged 75 years and over.

2012

Background and aims: We studied the effects of comprehensive geriatric assessment and multifactorial intervention on physical performance among older people. Methods: In a 3-year geriatric development project with an experimental design, 668 participants aged 75–98 were assigned to intervention (n=348) or control (n=320) groups. The intervention group received comprehensive geriatric assessment with an individually targeted intervention for 2 years. The outcome measures—performance in the Timed Up-and-Go (TUG), 10-meter walking and Berg Balance Scale tests 2 were gathered annually during the intervention and the 1-year follow-up after it. Results: With linear mixed models, over the 2-year i…

Using the Updated EWGSOP2 Definition in Diagnosing Sarcopenia in Spanish Older Adults : Clinical Approach

2021

Recently the European Working Group on Sarcopenia in Older People (EWGSOP2) has updated diagnostic criteria for sarcopenia, which consist of one or more measures of muscle strength, muscle mass, and physical performance, plus an initial screening test called SARC-F. The main objective was to compare the number of cases of sarcopenia, using the different measurements and screening options. A cross-sectional study was conducted on Spanish older adults (n = 272, 72% women). Combining the different measures proposed by the steps described in the EWGSOP2 algorithm, 12 options were obtained (A–L). These options were studied in each of the three models: (1) using SARC-F as initial screening

Physical performance in relation to menopause status and physical activity

2018

Objective: The aim of this study was to examine differences in physical performance (muscle power, muscle strength, aerobic capacity, and walking speed) across menopausal stages and potential of leisure physical activity (PA) to modify the impact of menopause on physical performance. Methods: In this cross-sectional study, women aged 47 to 55 were randomly selected from the Finnish National Registry and categorized as premenopausal (n ¼ 233), perimenopausal (n ¼ 381), or postmenopausal (n ¼ 299) based on serum concentrations of follicle-stimulating hormone and bleeding diary. Physical performance was measured by knee extension force, handgrip force, vertical jumping height, maximal walking …

Carnitine et performance physique

2003

Resume Objectif. – L’objectif de cette publication est de preciser l’implication de la carnitine dans le fonctionnement normal de la cellule musculaire et d’evaluer l’interet que pourrait representer pour les performances physiques une supplementation en carnitine. Actualites. – Recemment, de nouvelles informations concernant la voie de la biosynthese de la carnitine ainsi que de son transport dans les cellules musculaires ont ete publiees. Les bases moleculaires des deficiences en carnitine ont notamment ete identifiees permettant ainsi de mieux comprendre les mecanismes controlant l’utilisation de la carnitine dans ces cellules. Une analyse aussi exhaustive que possible a ete menee afin d…

A quantitative approach for assessing significant improvements in elite sprint performance: Has IGF-1 entered the arena?

2012

The introduction of doping substances and methods in sports triggers noticeable effects on physical performance in metric sports. Here, we use time series analysis to investigate the recent development in male and female elite sprinting performance. Time series displaying the average of the world's top 20 athletes were analyzed employing polynomial spline functions and moving averages. Outstanding changes in performance over time were statistically analyzed by Welch's t-test and by Cohen's measurements of effect. For validation we exemplarily show that our analysis is capable of indicating the effect of the introduction of in- and out-of-competition doping testing on women's shot put as wel…
