How do the physical and physiological demands of training and official football match for recreational players compare to those of semi-professionals?

Playing football at very different competitive levels can lead to different physical and physiological demands. Daily routines of these practitioners can also show differences in terms of leisure time, main professional occupations, among other activities. Therefore, understanding the physical and physiological demands between recreational and Semi-Professional players is crucial for designing appropriate training programs and assessing potential health benefits.

Definitions of determinants of physical activity behaviour: process and outcome of consensus from the DE-PASS expert group.

Background: Despite extensive research on physical activity behaviour (PAB), consensus is lacking on related terms and definitions, thereby hindering the ability to compare findings between studies and to develop reliable assessment tools. This study therefore aimed to establish consensus on the definitions of key PAB determinants.

Methods: First, an international expert steering committee was established, comprising members of the European Cooperation in Science and Technology (COST) action "DEterminants of Physical ActivitieS in Settings" (DE-PASS).

Sensory Analysis Performed within Augmented Virtuality System: Impact on Hedonic Scores, Engagement, and Presence Level.

Sensory analysis methodologies are performed in sensory booths designed to minimise external stimuli, lacking ecological validity. Immersive environments are used to introduce contextual cues, but there is a lack of studies using mixed reality systems. The main goal of this study was to evaluate an augmented virtuality (AV) system where participants are inserted into a virtual environment and evaluate a real product, being able to interact with both dimensions.

Consumption of edible insects and insect-based foods: A systematic review of sensory properties and evoked emotional response.

Low consumer acceptance of edible insects and insect-based products is one of the main barriers to the successful implementation of entomophagy in Western countries. This rejection is mainly caused by consumers' negative emotional responses, psychological/personality traits, and attitudes toward food choices. However, as the role of intrinsic product characteristics on such food choices has not been adequately studied, a systematic review was conducted following the PRISMA method, to analyze studies that have assessed hedonic evaluations, sensory profiling, or emotional responses to edible insects or insect-based products.

Dissemination, Implementation, and Evaluation of an Effective School-Based Intervention to Promote Physical Activity in Adolescents: A Study Protocol.

Adolescents around the world do not engage in sufficient physical activity and the Spanish context is no exception. Understanding the educational context as a complex system, school-based multi-level and multi-component interventions seem to be an effective strategy to reverse this trend. Moreover, a co-creational approach seems to facilitate the mobilization of community partnerships and the engagement of stakeholders in the intervention process.

Cardiorespiratory Fitness, Obesity and Physical Activity in Schoolchildren: The Effect of Mediation.

There are only a few studies that have examined the interaction between physical activity (PA), cardiorespiratory fitness (CRF), and overweightness/obesity in adolescents, and these studies have shown some limitations. The objective of this study was to examine whether the association between PA (moderate-vigorous PA [MVPA], moderate PA [MPA], and vigorous PA [VPA]) and obesity is mediated by CRF. This cross-sectional study was conducted in six middle and high-schools in the Porto district (Portugal), comprising 632 children and adolescents.

DE-PASS Best Evidence Statement (BESt): modifiable determinants of physical activity and sedentary behaviour in children and adolescents aged 5-19 years-a protocol for systematic review and meta-analysis.

Introduction: Physical activity among children and adolescents remains insufficient, despite the substantial efforts made by researchers and policymakers. Identifying and furthering our understanding of potential modifiable determinants of physical activity behaviour (PAB) and sedentary behaviour (SB) is crucial for the development of interventions that promote a shift from SB to PAB. The current protocol details the process through which a series of systematic literature reviews and meta-analyses (MAs) will be conducted to produce a best-evidence statement (BESt) and inform policymakers.

Therefore, monitoring physical activity is of utmost importance. However, there is a lack of data on objectively measured physical activity behaviors in HD patients.

Oncoplastic Surgery: Does Patient and Medical Specialty Influences the Evaluation of Cosmetic Results?

Background: Oncoplastic surgery (OS) has added plastic surgery concepts and techniques to the breast cancer surgery. However, reports of the impact of OS on cosmesis after breast-conserving surgery (BCS) are limited in the literature.

Patients And Methods: This cross-sectional prospective study included patients who underwent BCS.

Accelerometry calibration in people with class II-III obesity: Energy expenditure prediction and physical activity intensity identification.

Background: Almost all accelerometer calibration studies were developed for non-obese people, which hampers an accurate prediction of energy expenditure (EE) and induces a misclassification of sedentary activity (SA) and physical activity intensities (PAI) in class II-III obese people.

Research Question: The purpose of this study was to develop regression equations to predict EE and cut-points to classify SA and PAI in severe obese people based on several metrics obtained from hip and back accelerometer placement data.

Methods: 43 class II-III obese participants performed a protocol that included sitting and standing positions and walking at several speeds.

Allergic risks of consuming edible insects: A systematic review.

The expected future demand for food and animal-derived protein will require environment-friendly novel food sources with high nutritional value. Insects may be one of such novel food sources. However, there needs to be an assessment of the risks associated with their consumption, including allergic risks.

Cardiorespiratory fitness, but not physical activity, is associated with academic achievement in children and adolescents.

Background: Cardiorespiratory fitness (CRF) and physical activity (PA) seem to have positive effects on academic achievement (AA), although in most studies, objective methods of assessment have not been used.

Aim: To examine the associations of CRF and PA with AA.

Subjects And Methods: A sample of 640 youngsters (10-18 years) participated in this cross-sectional study.

Reliability and validity of 6MWT for outpatients with schizophrenia: A preliminary study.

Although the 6-minute walk test (6MWT) has been widely used in patients with schizophrenia, there is a lack of scientific evidence about its reliability and validity in this population. The first goal of this study was to explore the test-retest reliability of the 6MWT and to identify the associated parameters that contribute to the variability of the distance walked during the 6MWT in outpatients with schizophrenia. The second goal was to assess the criterion validity of the 6MWT in men with schizophrenia.
