Ohmic Contacts on p-Type Al-Implanted 4H-SiC Layers after Different Post-Implantation Annealings
2019
This paper reports on the electrical activation and Ohmic contact properties on p-type Al-implanted silicon carbide (4H-SiC). In particular, the contacts were formed on 4H-SiC-implanted layers, subjected to three different post-implantation annealing processes, at 1675 °
Application of the discussion groups and initial phases of the qfd methodology to the study of Valencian ball trinquetes
2011
Montaner AM, Montaner C, Perez-Soriano P, Carrasco-Embuena V, Llana-Belloch S. Application of the discussion groups and initial phases of the qfd methodology to the study of valencian ball trinquetes. J. Hum. Sport Exerc. Vol. 6, No. 4, pp. 629-638, 2011. The purpose of this research is to show an opinion study about the specifications that the valencian ball trinquetes should have according to the players’ opinion. The valencian ball game is a native sport with a great cultural tradition in the Valencian Community and it has been practised in the trinquetes since the XIV century. Despite its history, these facilities do not have the normative requirements for suitable sport development. Th…

Eighty-four male finishers in the ‘Half Marathon Basel’ completed the race distance within (me…
Physical exercise in the prevention and treatment of Alzheimer's disease
2020
Highlights • Low levels of physical activity are a risk factor associated with Alzheimer's disease. • Older adults who exercise are more likely to maintain cognition. • Exercise modulates amyloid β turnover, inflammation, synthesis, and release of neurotrophins, and cerebral blood flow.
Estimation of aerobic fitness among young men without exercise test
2015
Summary Study aim: to develop and estimate the validity of non-exercise methods to predict VO2max among young male conscripts entering military service in order to divide them into the different physical training groups. Material and methods: fifty males (age 19.7 ± 0.3 years) reported their physical activity before military service by IPAQ and SIVAQ questionnaires. Furthermore, Jackson’s non-exercise method was used to estimate VO2max. Body mass and height were measured, body mass index calculated and VO2max measured directly in a maximal treadmill test. Subjects were randomly divided into two groups. The results of the Group 1 (N = 25) were used to develop a regression equation to estimat…
Physical activity, fitness, and all-cause mortality: An 18-year follow-up among old people
2016
Background: Little is known about change in physical activity (PA) and its relationship to all-cause mortality among old people. There is even less information about the association between PA, fitness, and all-cause mortality among people aged 80 years and above. The objective is to investigate persistence and change in PA over 5 years as a predictor of all-cause mortality, and fitness as a mediator of this association, among people aged 80 and 85 years at the beginning of an 18-year mortality follow-up period. Methods: Using Evergreen Project data (started in 1989), 4 study groups were formed according to self-reported changes in PA level, over a 5-year period (starting in 1989–1990 and e…
Handgrip strength and health outcomes: Umbrella review of systematic reviews with meta-analyses of observational studies
2020
Highlights • We carried out an umbrella review of systematic reviews with meta-analyses of observational studies on handgrip strength and all health outcomes. • Three outcomes (lower all-cause mortality, lower cardiovascular mortality, and lower risk of disability) were found to have highly suggestive evidence. • One outcome (chair rise performance over time) was found to have suggestive evidence. • Five outcomes (walking speed, inability to balance, hospital admissions, cardiac death, and mortality in those with chronic kidney disease) were found to have weak evidence.
Lifetime Adherence to Physical Activity Recommendations and Fall Occurrence in Community-dwelling Older Adults: a Retrospective Cohort Study
2012
Wright RL, Robinson PD, Peters DM. Lifetime adherence to physical activity recommendations and fall occurrence in community-dwelling older adults: a retrospective cohort study. J. Hum. Sport Exerc. Vol. 7, No. 1, pp. 310-320, 2012. Falling is a major health concern for community-dwelling older adults. Regular physical activity has been proposed to prevent falls. The aim of this study was to assess whether the achievement of the 2004 UK Department of Health physical activity recommendations over a lifetime had a protective effect against falling in older people. 313 community-dwelling older adults completed a questionnaire about lifetime physical activity and fall occurrence. There were sign…
Regular exercise history as a predictor of exercise in community-dwelling older Japanese people
2012
A physically active lifestyle is important across the entire life span. However, little is known about life-long participation in regular exercise among older people. The purpose of the present study was to describe regular exercise throughout a person's lifetime and evaluate the impact of exercise earlier in life on participation in exercise at age 60 and over. The participants were 984 community-dwelling older people aged 60 to 86 years. Each participant's life was divided into five age categories: 12-19, 20-29, 30-39, 40-59, and 60 years and over. The association between exercise at an earlier age and that at 60 years and over was assessed using logistic regression analysis adj…
