Reliability and Accuracy of Linear Position Transducers During the Bench Press ...
Montoro-Bombú, Raynier; Costa, Armando; Sousa, Paulo Malico; Pinheiro, Valter; Forte, Pedro; Monteiro, Luis; Ribeiro, Alex S.; Rama, LuisSelecting the right linear position transducer (LPT) for velocity-based training monitoring sometimes presents uncertainties for coaches. Objectives: This study rigorously examined the test-retest reliability of three LPT–Cs using a simultaneous triangulation method of the same device during bench press (BP) and back squat (SQ) exercises performed on a Smith machine. Methods: Forty university students—13 female...
Dual task performance and history of falls in community-dwelling older adults
Tomas-Carus, Pablo; Biehl-Printes, Clarissa; Pereira, Catarina; Veiga, Guida; Costa, Armando; Collado-Mateo, DanielIntroduction: Falls are a common problem for older adults, and the identification of people at high risk of falling is a major challenge to health systems. Objective: To evaluate the association between the history of falls and single-task Timed Up and Go Test (single TUG) or dual-task TUG variables. Methods: Three hundred seventy seven community-dwelling older persons, with ages ranging from 65 and 92 years, p...
Gerontomotricidade. Programa de exercício físico para pessoas idosas.
Printes, Clarissa; Costa, Armando; Marmeleira, José; Tomas-Carus, PabloEnvelhecer bem e de forma bem sucedida é o que todas as pessoas aspiram.O desejo humano em acrescentar anos de vida saudável no decorrer da sua velhice tem ganhado cada vez mais reconhecimento à luz dos olhos da comunidade científica, médica e sociedade civil. Este despertar da motricidade humana para o campo da gerontologia enquadra-se num paradigma desenvolvimental salutogénico em que bem estar e qualidade de...
Mudança para um estilo de vida ativo no envelhecimento: uma proposta de um estu...
Biehl-Printes, Clarissa; Tomas-Carus, Pablo; Costa, ArmandoResumo: Introdução: Atualmente, a mudança para um estilo de vida ativo pela prática de exercício físico em programas para promoção da saúde vem assumindo relevo. Entretanto, as taxas de adesão pelos idosos são diminutas. Objetivos: Conhecer os níveis de adesão dos idosos em instituições desportivas, bem como os motivos de adesão ou desistência a programas de exercício físico; Conhecer o papel do exercício físic...
A comparative study of the functional fitness and perception of quality of life...
Biehl-Printes, Clarissa; Texeira, Diogo; Costa, Armando; Pinheiro, Valter; Sousa, Paulo; Cruz, Joana; Tomas-Carus, PabloAbstract - Objectives: To analyze the contributions of Universities of third age (U3A) through their proposed activities and effects in functional fitness and quality of life of elderly participants and non-participants. Methods: The sample was composed of two groups: elderly participants in U3A (EPG; n=25) and elderly non-participants (ENPG; n=25). Data collection was obtained through questionnaires: one about...
Improving elms performance under drought stress: the pretreatment with abscisic...
Dias, Maria Celeste; Oliveira, Helena; Costa, Armando; Santos, ConceiçãoHormonal conditioning of plants in order to increase photosynthetic performance and reduce oxidative stress may improve plants' tolerance to stress. This study aims to elucidate the effects of ABA pretreatment on the photosynthetic apparatus and antioxidant battery of Ulmus minor plants under well watered (WW) and drought stress (DS) conditions. Leaves were sprayed with ABA (50 and 100??M). After 25 days of tre...
Water stress and recovery in the performance of two Eucalyptus globulus clones:...
Correia, Barbara; Pintó-Marijuan, Marta; Neves, Lucinda; Brossa, Ricard; Dias, Maria Celeste; Costa, Armando; Castro, Bruno B.; Araújo, ClaraEucalyptus plantations are among the most productive forest stands in Portugal and Spain, being mostly used for pulp production and, more recently, as an energy crop. However, the region's Mediterranean climate, with characteristic severe summer drought, negatively affects eucalypt growth and increases mortality. Although the physiological response to water shortage is well characterized for this species, evide...
NaCl and Phaeomoniella chlamydospora affect differently starch and sucrose meta...
Oliveira, Helena; Costa, Armando; Santos, ConceiçãoVineyards production is often affected by diseases as esca and Petri disease and by excess of salt. Phaeomoniella chlamydospora is one of the pathogenic fungi associated to esca disease, but its interaction with the plant under excess of salt remains unknown. Under controlled in vitro conditions, Vitis vinifera L. plants were exposed to 0, 20 and 100 mM NaCl and inoculated with P. chlamydospora. Both inoculatio...
Acclimatization of secondary somatic embryos derived plants of Eucalyptus globu...
Pinto, Glória; Silva, Sónia; Loureiro, João; Costa, Armando; Dias, Maria Celeste; Araújo, Clara; Neves, Lucinda; Santos, ConceiçãoThis paper reports the complete process from secondary emblings (SE-derived plants) regeneration to acclimatization of Eucalyptus globulus and describes histocytological changes that occur in leaves from in vitro to ex vitro acclimatization for a 3-month period. After elongation, plantsweretransferredtopotswithsterilizedpeat:perliteand acclimatized in a phytotron, with progressive reduction of RH and increaseof...
Genetic stability evaluation of Quercus Suber L. Somatic embryogenesis by RAPD ...
Fernandes, Pedro; Costa, Armando; Santos, Conceição; Rocha, CristinaA reliable protocol for adult Quercus suber L. somatic embryogenesis (SE) was developed recently. To evaluate the potential use of this protocol in cork oak forest breeding programs, it is essential to guarantee somatic embryos/emblings genetic stability. Random Amplification of Polymorphic DNA (RAPD) is currently used to assess somaclonal variation providing information on genetic variability of the micropropa...
