    Purpose: The current study investigated the impact of gender (men vs. women) and cardiovascular fitness status (active vs. sedentary) on heart rate variability (HRV) [standard deviation of NN intervals (SDNN), root mean square of successive RR interval differences (RMSSD), low-frequency (LF), high-frequency (HF)] following performing an exhaustive exercise in an air-polluted environment. In addition, we measured the impact of gender (men vs. women) and cardiovascular fitness status (active vs. sedentary) on the cardiorespiratory indices [e.g., the myocardial volume oxygen (MvO 2 ), forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC)] at pre- and post-exercise status in an air-polluted environment. Method: 120 participants (46 ± 5 years) were classified into experimental and control categories and two subgroups; including physical fitness status (active vs. sedentary) and sexes (men vs. women). The heart rate variability and cardiorespiratory indices were measured at different times of performing the exhaustive exercise. Results: At rest condition, higher MvO 2 values were detected in the experimental groups in comparison to women in the control groups ( p < 0.001). Performing the exhaustive exercise in the polluted ambient caused lower RMSSD and higher MvO 2 indices in experimental groups ( p < 0.001). Exposure to air pollution could negatively alter cardio-autonomic and respiratory systems among sedentary and active women ( p < 0.001). Conclusion: In air-polluted ambient, the exhaustive exercise increases myocardial stress in both sexes, regardless of cardiovascular fitness status.

    Hot issues and frontier fields of youth sports literacy

    by Zhi-Chao Yuan, Lin-Lin Yang

    Insight - Sports Science, Vol.6, No.1, 2024; 11 Views

    To accurately grasp the forefront hotspots and developmental trends in current research on youth sports literacy, we employed the “Web of Science” core collection database to gather 432 relevant literature pieces pertaining to “youth sports literacy”. Using the CiteSpace analysis software and leveraging methodologies such as scientific knowledge mapping, we systematically reviewed and synthesized the literature, ultimately constructing a knowledge structure map that illustrates the research hotspots and cutting-edge trends. The findings of this study reveal that research on youth sports literacy is predominantly concentrated in developed countries and regions such as the United States, Australia, and Canada. The definition and conceptualization of sports literacy represent the fundamental research questions. Research hotspots are primarily clustered around three major themes: Youth sports literacy in relation to public health, physical education, and mental well-being. The emphasis on research frontiers varies across different periods: The period from 2007 to 2012 reflects a focus on psychological promotion; 2013 to 2018 emphasizes holistic physical and mental well-being promotion; and 2019 to 2022 represents a phase centered around health promotion. Overall, a trend towards integrated research in youth sports literacy is evident. The wealth of knowledge clusters and impactful research achievements have laid a robust foundation for the study of youth sports literacy.

    Analysis of the internal and external loads, and technical actions of small-sided games in soccer

    by Nuno André Nunes, Gavin Comber, Grégory Hallé Petiot, Mathew Coley

    Insight - Sports Science, Vol.6, No.1, 2024; 250 Views

    The priority in team sport training like soccer is the acquisition and refinement of individual and group skills as well as tactics to transform the group into an effective competitive unit. To achieve these objectives, it is common for coaches to reduce both the number of players and the field dimensions to manipulate exercise intensity, catering for the specific needs of their players. The use of small-sided games (SSGs) that feature less participant has proven a practical tool for coaches, for the development of technical, tactical, and physical abilities. The objective of this paper is to conduct a review of the literature on the topic of small-sided games to analyze specific parameters such as physiological, technical, and movement duration. The effectiveness of SSGs in enhancing aerobic and anaerobic capacities as well as technical skills is often highlighted although their main benefit might be to practice decision-making and problem-solving under pressure, replicating game-like situations. Examining the psychological aspects during small-sided games, such as confidence, motivation, enjoyment, and cognitive engagement, could also provide insights into optimizing training programs and enhancing player development. In summary, small-sided games offer diverse benefits for physical, technical, tactical development in players across different age groups and skill levels for both training and/or learning purposes. Future research should thus focus on investigating the long-term effects of small-sided games on players’ physical and technical development, as well as their transfer to actual match performance.

    Post-retirement transition: Challenges and support strategies for professional football players

    by George Yiapanas

    Insight - Sports Science, Vol.6, No.1, 2024; 36 Views

    The career lifespan of professional football players is often notably brief, typically spanning only a few years, which presents unique challenges when transitioning to life after retirement. Despite the inevitability of this transition, many football players find themselves inadequately prepared for the abrupt change from the structured environment of professional sports to the broader, less predictable professional world. This study seeks to identify the factors influencing the duration of their sports careers, explore the various challenges when transitioning to post-football life, and offer a set of recommendations for enhancing the various support systems. The study highlights 2025s the importance of a proactive and holistic approach to career transition, advocating for integrating comprehensive support systems that address these challenges well before retirement, helping as many retired football players as possible transition into entrepreneurial roles or start new ventures. Existing programs that support this transition are examined, with findings pointing to the need for tailored guidance, continuous education, and robust mentorship as critical components of successful transition strategies. It demonstrated that Human Resource Management [HRM] strategies are crucial for helping football players adapt to post-retirement life, offering support in various areas such as skills development, mental health, re-employment prospects and career redirection. This study contributes to the broader discourse on athlete welfare and underscores the need for continued investment in support mechanisms to ensure the well-being of professional football players both during and after their careers. By focusing on these areas, the study aims to foster environments that not only prepare football players for their eventual transition but also enable them to thrive in life beyond the playing field.

    Postural myoadaptive disorders in short track athletes

    by Yuri Olegovich Novikov, Anna Sergeevna Yasinskaya, Sofya Marsovna Musina

    Insight - Sports Science, Vol.6, No.1, 2024; 33 Views

    Our article is the first to conduct a study of short track athletes in the Russian Federation, which revealed the presence of postural muscle changes in the back. The study used a neuro-orthopedic examination, original instruments and a questionnaire method. Our article is the first step towards studying postural myodaptive disorders in short track athletes.
