Validity of three smartwatches in estimating energy expenditure during outdoor walking and running.

2022

Commercially wrist-worn devices often present inaccurate estimations of energy expenditure (EE), with large between-device differences. We aimed to assess the validity of the Apple Watch Series 6 (AW), Garmin FENIX 6 (GF) and Huawei Watch GT 2e (HW) in estimating EE during outdoor walking and running. Twenty young normal-weight Chinese adults concurrently wore three index devices randomly positioned at both wrists during walking at 6 km/h and running at 10 km/h for 2 km on a 400- meter track. As a criterion, EE was assessed by indirect calorimetry (COSMED K5). For walking, EE from AW and GF was significantly higher than that obtained by the K5 (p < 0.001 and 0.002, respectively), but…

Perceived Opportunities for Physical Activity and Willingness to Be More Active in Older Adults with Different Physical Activity Levels

2021

This study examined equity in physical activity (PA) by investigating whether perceived opportunity for PA was associated with willingness to be more active. Among community residents (75, 80, or 85 years old, n = 962) perceived opportunity for PA (poor and good), willingness to be more active (not at all, a bit, and a lot), and level of PA (low, moderate, and high) were assessed via questionnaires. Multinomial logistic regression showed that physical activity moderated the association between poor opportunity and willingness to increase PA. Among those with moderate PA, poor opportunity for PA increased the odds of willingness to be a lot more active (multinomial odds ratio, mOR 3.90, 95% …

Task-Specific Organic Salts and Ionic Liquids Binary Mixtures: A Combination to Obtain 5-Hydroxymethylfurfural From Carbohydrates

2019

The increase in energy demand and depletion of fossil fuels are among major issues of modern society. Valorization and transformation of raw materials in products of industrial value represents a challenge. This justifies the growing interest of scientific research towards the identification of suitable media and methodologies able to pursue above goals, paying attention to matter of sustainability. On this subject, we studied sulfonic-acid functionalized diimidazolium salts as catalysts for the conversion of fructose and sucrose to 5-hydroxymethylfurfural (5-HMF) in an ionic liquid mixture. In general, using these salts allowed us to obtain 5-HMF in good yields from both substrates in mild…

Chemosensory reactivity and food neophobia in preschool children: impact of smell, but not of taste

2014

Context and objective: Recent studies suggested that sensory sensitivity could be linked to food neophobia, described as the reluctance to eat, or the avoidance of, new foods. The objective of the present study was twofold. Firstly, this study aimed at assessing the links between smell reactivity and taste reactivity in children. Secondly, this study assessed the links between children’s smell/taste reactivity and food neophobia. The hypothesis was that the higher the chemosensory reactivity of the child, the more the child is neophobic. Method: One hundred and three dyads of mother-child, from the Opaline cohort, were involved. The child’s food neophobia was assessed using a validated pare…

Smell but not taste reactivity is related to food neophobia in toddlers: results from the Opaline cohort

2014

National audience; Context and objective: Research has previously identified relationships between chemosensory reactivity and food neophobia in toddlers. However, most studies have addressed this question using declarative data, and without analyzing separately smell and taste. The objective of the present study was twofold. The first objective was to assess the relationships between olfactory reactivity and taste reactivity in toddlers, using experimental designs with different tastants and odorants. The second objective was to determine the relationships between olfactory /taste reactivity and food neophobia in toddlers. The hypothesis was that the higher the chemosensory reactivity of t…

Models of tax payments of performers of economic activity in Latvia

2019

Economic theory sources widely discuss the fiscal policy, the ways of encouraging economic development, improve the welfare of people, improve employment and promote progress by fiscal instruments. On one side, it is possible to use the expenditure policy, on the other side, tax revenue can be optimised by reducing tax gaps. State officials often view self-employment as a missed opportunity deserving more focused attention. The European Union also supports this position. The question of self-employment is important for performers of economic activity. The aim of the research: on the basis of theoretical (legislative) and empirical analysis to find out advantages and disadvantages of tax pay…

Influencia del docente y la docente, la metodología y el contenido de las clases de educación física en la percepción de estudiantado chileno

2021

Resumen Introducción. La relevancia de la educación en la sociedad actual es evidente, por ello, es de vital importancia conocer la percepción de los diversos actores que interactúan en esta, en particular, la del estudiantado sobre las metodologías y contenidos que ofrece el profesorado es determinante en el proceso de enseñanza-aprendizaje. Objetivo. Conocer la percepción que reportan estudiantes de tres centros educativos de la región de Valparaíso (Chile), en relación con la satisfacción por las actividades deportivas, la clase de educación física y la función del personal docente. Metodología. Se utilizó una escala de 12 ítems agrupadas en tres dimensiones. Se aplicó una escala de perc…

Socialization Into Teaching Physical Education – Acculturative Formation of Perceived Strengths

2015

1. IntroductionIt is common that physical education (PE) in primary schools is taught by generalist class teachers. They have been found to possess strong socially constructed beliefs about teaching and their teaching competencies already before they enter formal teacher preparation. These beliefs act as filters when acquiring and interpreting new information thus influencing what is learned during the formal teacher preparation (Capel & Katene, 2000; Curtner-Smith, 2001; Doolittle, Dodds, & Placek, 1993; Hutchinson, 1993; Lawson, 1983; Lortie, 1975; Matanin & Collier, 2003; Pajares, 1992; Placek, Dodds, Doolittle, Portman, Ratliffe & Pinkham, 1995; Randall & Maeda, 2010; Richardson, 2003).…

The Relationships between Pre-Service Primary Teachers’ Teaching and Instructing/Coaching Orientations, and Their Perceived Strengths in Teaching Phy…

2014

Abstract. This study explored if the orientations towards instructing/coaching in physical activities (PA) and teaching physical education (PE) affect the perceived strengths in teaching PE at the primary level (PSTPEs). The orientations were considered as socializing factors into teaching PE. In this study, the perceived strengths were divided into discipline - and pupil - focused strengths. Online questionnaire was used to collect the data from 386 first year pre - service primary teachers before their first PE course of formal teacher education, to expose the acculturative influences of the orientations. Cross tabulation and logistic regression were used to analyze the relationships. The…
