Children of Single Fathers Created by Surrogacy: Psychosocial Adjustment Considerations and Implications for Research and Practice.

The existence of single-father families formed by surrogacy is becoming a more visible reality, even though this type of family organization is still perceived with stigma and negative attitudes by more traditional sectors of society, because it raises some concerns regarding the psychosocial well-being of children who are born into single-fathers' families via surrogacy, and in many cases, to gay single men who wish to become fathers. On the other hand, available research on the psychosocial well-being of these children is still very scarce and limited to a handful of Western countries. Hence, it is of utmost importance to examine studies that explore the psychosocial adjustment of these children.

Within-week differences in external training load demands in elite volleyball players.

Purpose: The aim of this study was to analyze the within-week differences in external training intensity in different microcycles considering different playing positions in women elite volleyball players.

This study followed a longitudinal design, lasting 38 weeks. Twenty-five players (age: 15.

Ongoing Bidirectional Feedback between Planning and Assessment in Educational Contexts: A Narrative Review.

Quality in education is one of the 17 goals in the United Nations' sustainable agenda for 2030, presupposing careful planning and assessment of learning. Traditional planning in sports education (either in training or school settings) largely adopts pre-determined learning sequences and temporal milestones that, in theory, enhance the learning process. However, learning is a context-dependent, non-linear process with considerable intra- and interindividual variability, whereby planning and assessment should also be non-linear.

Differences in visual search behavior between expert and novice team sports athletes: A systematic review with meta-analysis.

Background: For a long time, in sports, researchers have tried to understand an expert by comparing them with novices, raising the doubts if the visual search characteristics distinguish experts from novices. Therefore, the aim of the present study was to review and conduct a meta-analysis to evaluate the differences in visual search behavior between experts and novices in team sports athletes.

Methods: This systematic review with meta-analysis followed the PRISMA 2020 and Cochrane's guidelines.

Weekly Training Load across a Standard Microcycle in a Sub-Elite Youth Football Academy: A Comparison between Starters and Non-Starters.

Compensatory training sessions have been highlighted as useful strategies to solve the differential weekly training load between the players' starting status. However, the influence of the players' starting status is still understudied in sub-elite youth football. Thus, the aim of this study was to compare the weekly training load on a standard microcycle in starters and non-starters of a sub-elite youth football academy.

The Influence of Abdominal Adiposity and Physical Fitness on Obesity Status of Portuguese Adolescents.

The aim of this study was to verify the relationship between abdominal adiposity and physical fitness in the obesity status of Portuguese adolescents. BMI, abdominal adiposity, and physical fitness tests from the FITescola were evaluated in a total of 654 Portuguese adolescents, aged 10-19 years old-male: = 334 (51%), female: = 320 (49%). For the final model, BMI was positively related with age ( 0.

Analyzing the within and between Players Variability of Heart Rate and Locomotor Responses in Small-Sided Soccer Games Performed Repeatedly over a Week.

Background: Small-sided games (SSGs) are drill-based and constrained exercises designed to promote a technical/tactical and physiological/physical stimulus on players while preserving some dynamics of the real game. However, as a dynamic game, they can offer some variability making the prediction of the stimulus hardest for the coach. Aim: The purpose of this study was to analyze the between-session and within-player variability of heart rates and locomotor responses of young male soccer players in 3v3 and 5v5 small-sided game formats.

Modeling the Major Influencing Factor on Match Running Performance during the In-Season Phase in a Portuguese Professional Football Team.

The aim of this study was two-fold: (1) to analyze the influence of season phase (i.e., the start of the in-season and mid-in-season) on match running performance in a Portuguese professional football team; (2) to determine and model the main factor influencing match running performance during the in-season in this specific football team.

Psychometric Validation of the Portuguese Version of the Modern Homonegativity Scale among Portuguese College Students.

The studies focused on analysing attitudes toward homosexuality show that the manifestation of homonegativity has evolved into more modern forms. We therefore propose using instruments that capture subtle aspects in discrimination against gay and lesbian people. The objective of this study is twofold.

Variability of internal and external loads and technical/tactical outcomes during small-sided soccer games: a systematic review.

Small-sided games (SSGs) are widely used in soccer training. However, some of the typical outcomes related to human responses during these games (namely internal and external load) may vary between sessions for similar practice conditions. Thus, the study of intra- and inter-bout variability in response to SSGs is progressively growing.
