Respiratory Muscle Strengths and Their Association with Lean Mass and Handgrip Strengths in Older Institutionalized Individuals
2020
The study of reduced respiratory muscle strengths in relation to the loss of muscular function associated with ageing is of great interest in the study of sarcopenia in older institutionalized individuals. The present study assesses the association between respiratory muscle parameters and skeletal mass content and strength, and analyzes associations with blood cell counts and biochemical parameters related to protein, lipid, glucose and ion profiles. A multicenter cross-sectional study was performed among patients institutionalized in nursing homes. The respiratory muscle function was evaluated by peak expiratory flow, maximal respiratory pressures and spirometry parameters, and skeletal m…
Large body size variation is linked to low communication success in tandem running ants
2019
AbstractDiversity in animal groups is often assumed to increase group performance. In insect colonies, genetic, behavioral and morphological variation among workers can improve colony functioning and resilience. However, it has been hypothesized that during communication processes, differences between workers, e.g. in body size, could also have negative effects. Tandem running is a common recruitment strategy in ants and allows a leader to guide a nestmate follower to resources. A substantial proportion of tandem runs fail because leader and follower loose contact. Using the ant Temnothorax nylanderi as a model system, we tested the hypothesis that tandem running success is impaired if lead…
Walking tourism in urban destinations: some preliminary results from a survey in Malaga with gps-based technologies
2018
Walking tourism in urban destinations can be defined as a sequence of day visits and/or a sequence of walking tours. In this work, GPS tracking data on spatio-temporal behaviour of walking tourists in Malaga are reported as case study. Malaga is a booming tourist destination characterized by a city centre, particularly suitable for a pedestrian visit. From 22nd January to 19th March 2018 for a total period of 41 days, a survey was carried out with a specific protocol: 103 interviews were conducted and 101 GPS valid tracks were collected. Walking tourists were systematically sampled, starting from the population of all tourists staying in the surveying day at some selected hotels in the city…
Genetics of maximal walking speed and skeletal muscle characteristics in older women.
2008
AbstractThe aim of this study was to examine whether maximal walking speed, maximal isometric muscle strength, leg extensor power and lower leg muscle cross-sectional area (CSA) shared a genetic effect in common. In addition, we wanted to identify the chromosomal areas linked to maximal walking speed and these muscle characteristics and also investigate whether maximal walking speed and these three skeletal muscle characteristics are regulated by the same chromosomal areas. We studied 217 monozygotic (MZ) and dizygotic (DZ) female twin pairs aged 66 to 75 years in the Finnish Twin Study on Aging study. The DZ pairs (94) were genotyped for 397 microsatellite markers in 22 autosomes and X-chr…
Indicators for sustainable pedestrian mobility
2012
Pedestrians walk everyday to satisfy their basic necessities. They need an environment that reflects their requirements and expectations, in other words "liveable" as much as possible. So we should offer tools that could allow a complete and clear evaluation of the existing walking environment, taking into account both pedestrian requirements and urban environment schemes. To measure pedestrian mobility performance we usually use indicators, which measure performances and grant a quick estimation of progress. Indicators are universally acknowledged synthetic and standard parameters that should help policy makers gauge whether things are going in the right direction or not. They should be ou…
Relationship among Body Composition, Adipocytokines, and Irisin on Exercise Capacity and Quality of Life in COPD: A Pilot Study
2022
Adipose tissue is an endocrine organ that interferes with the severity of chronic obstructive pulmonary disease (COPD). Although inflammatory markers, body composition, and nutritional status have a significant impact on pulmonary function, the real contribution of adipocytokines and myokines in COPD is still controversial. We aimed to evaluate the role played by the body composition, leptin, adiponectin, haptoglobin, and irisin on the functional exercise capacity, respiratory function, and quality of life (QoL) in COPD. In 25 COPD (20% GOLD-1; 60% GOLD-2; 20% GOLD-3) patients and 26 matched control subjects, we find that leptin, total adiponectin and haptoglobin are significantly increased…
Weakly interacting dark matter in walking technicolor theories
2010
Several lines of evidence support the existence of the dark matter in the Universe. In the light of the present observations the particle dark matter, and in particular the WIMP scenario is a very promising alternative to solve the dark matter problem. In this context recent minimal walking techicolor model motivated dark matter models have been studied. The minimal walking techinicolor and the minimal extension of it, which can successfully provide a dynamical origin for the electroweak symmetry breaking as well as the unification of the standard model coupling constants, gives rise to natural dark matter candidates such as fourth family heavy neutrinos and SU(2) adjoint matter. A general …
El Incremental Shuttle Walking Test en personas mayores con enfermedad coronaria isquémicas : estudio preliminar
2013
Introducción: En las personas mayores, la enfermedad coronaria isquémica (ECI) es la principal causa de mortalidad y morbilidad. Los cambios cardiovasculares y las comorbilidades asociados al envejecimiento, además del miedo a las condiciones adversas de la enfermedad así como la alta predisposición a la depresión y aislamiento social, resultan en un ciclo de inactividad y desacondicionamiento que disminuyen la capacidad funcional del mayor. Para ellos, los programas de Rehabilitación Cardíaca (RC) basados en ejercicio físico están especialmente indicados. El entrenamiento físico del paciente añoso debe adaptarse a sus características clínicas, siendo esencial la valoración de su capacidad …
The Mediating Role of C-Reactive Protein and Handgrip Strength Between Obesity and Walking Limitation
2008
OBJECTIVES: To study the association between different obesity indicators and walking limitation and to examine the role of C-reactive protein (CRP) and handgrip strength in that association. DESIGN: A cross-sectional, population-based study. SETTING: The Health 2000 Survey with a representative sample of the Finnish population. PARTICIPANTS: Subjects aged 55 and older with complete data on body composition, CRP, handgrip strength, and walking limitation (N=2,208). MEASUREMENTS: Body composition, anthropometrics, CRP, medical conditions, handgrip strength, and maximal walking speed were measured in the health examination. Walking limitation was defined as maximal walking speed less than 1.2…
