The Influence of Sport Practices on Body Composition, Maturation and Maximum Oxygen uptake in children and youth (La influencia de las prácticas deportivas en la composición corporal, la maduración y la absorción máxima de oxígeno en niños y jóvenes)

Systematic sport practice at younger ages positively influences body composition and maximum oxygen uptake (VO2max). On the other hand, its influence on maturation is still not consensual, and some studies claim a negative effect. Few studies have approached the differences in this influence according to different sport practices. The present study aims to analyse and compare the influence of karate and swimming practices, and the non-practice of sports, on body composition, VO2max and maturation in children and youth. Data were collected in 126 youth, 54 karate athletes, 36 swimming athletes and 36 participants with no sport practice (M=11.56±2.06 years). The type of sport practice had a different influence on body composition and VO2max, no negative influence was verified on maturation. In general, the sport practices revealed a positive influence in children and youth’s body composition. The karate practice provided significant lower body fat mass and higher lean mass in males. Swimming athletes revealed a significant higher VO2max compared to all other groups, while karate didn´t differed from no-practice group. The different influence of sport practices verified highlighted the importance of a multilateral development of children and youth by practising several sports. Resumen: La práctica deportiva sistemática a edades más tempranas influye positivamente en la composición corporal y la absorción máxima de oxígeno (VO2max). Por otro lado, su influencia en la maduración aún no es consensuada, y algunos estudios afirman un efecto negativo. Pocos estudios se han acercado a las diferencias en esta influencia según las distintas prácticas deportivas. El presente estudio tiene como objetivo analizar y comparar la influencia de las prácticas de kárate y natación, y la no práctica de deportes, sobre la composición corporal, el VO2máx y la maduración en niños y jóvenes. Los datos fueron recolectados en 126 jóvenes, 54 atletas de kárate, 36 atletas de natación y 36 participantes sin práctica deportiva (M = 11.56 ± 2.06 años). El tipo de práctica deportiva influyó de manera diferente en la composición corporal y el VO2max, no se verificó influencia negativa en la maduración. En general, las prácticas deportivas revelaron una influencia positiva en la composición corporal de niños y jóvenes. La práctica del karate proporcionó una masa grasa corporal significativamente más baja y una masa magra más alta en los hombres. Los atletas de natación revelaron un VO2max significativamente más alto en comparación con todos los demás grupos, mientras que el karate no difirió del grupo sin práctica. La diferente influencia de las prácticas deportivas verificada resaltó la importancia de un desarrollo multilateral de la niñez y la juventud a través de la práctica de varios deportes.

Psychophysiological and Psychosocial Profile of Patients Attending Drug Addiction Centers

Drug treatment centres provide the highest level of rehab services for patients diagnosed with drug addictions. Most inpatient drug rehab programs focus on medical detox and mental health interventions. However, how to optimize the later remains a challenge. The aim of this study was to examine the psychophysiological and psychosocial profile of patients attending drug addiction centres in comparation with the general population. A total of 105 inpatient drug rehab patients and 50 participants from the general population were compared based on standardized psychophysiological and psychosocial measures. Results of this study suggest that patients attending drug addiction centers differ from general population in several different psychophysiological and psychosocial factors. Patients reported significantly lower levels of physical activity and increased sympathetic responsiveness, and significantly higher levels in loneliness, psychologically inflexibility and neuroticism. The results of this study highlight the importance of address healthy lifestyle behaviors such as sport practice and psychological variables such as loneliness, psychological (in)flexibility and neuroticism to improve current programs aim to prevent or reduce problematic drug consumptions.

Understanding the Prevalence Rates of Interpersonal Violence Experienced by Young French-Speaking Swiss Athletes

Facing the important methodological limitations of the instruments used for assessing the prevalence of interpersonal violence faced by young athletes, the aim of the present study was to propose and describe the use of a research instrument adapted to young and French-speaking athletes. In addition, by collecting preliminary data with a Swiss sample, we aimed to measure the different forms of interpersonal violence young athletes have experienced at least once during their sport practice. Our questionnaire was based on three existing questionnaires and adapted for a young audience. Regarding prevalence, results showed that among the 210 respondents, 75% declared psychological violence, 53% physical violence, 28% sexual violence and 21% reported no violence. The other results showed that this instrument appears to be well-structured to measure interpersonal violence and understandable for young athletes. Based on the strengths and limits of our instrument, the methodological need of standardization of research instruments is discussed in line with a need of more studies to fully understand the phenomenon.

Physical Activity, Sport Practice and Cardiovascular Risk Factors in Workers From a Public Hospital: A Trajectory Analysis

Background: Studies have demonstrated the positive effects of physical activity on cardiovascular risk factors. Longitudinal studies using modeled trajectories are necessary to understand patterns of physical activity and association with cardiovascular risk factors.Objective: To analyze the association between sports practice in young people and current physical activity with the trajectory of cardiovascular risk factors in workers at a public hospital.Methods: Four hundred and seventeen workers was followed for four years reporting Physical Activity, health status, lifestyle behaviors and socio-demographic characteristics. Group-based trajectory modeling identified the trajectories of PA and associations with time-stable and time-varying covariates. We considered a range of sociodemographic and health and lifestyle factors as potential covariates.Results: The results shows the association between participation in sports activities in youth and current physical activity and trajectories of cardiovascular risk, adjusted for sex and age (p < 0.05). Adults who reported having played sports in their youth and are currently active have a lower risk of having a history of obesity and low HDL-c than workers who did not play sports in their youth and are currently sedentary 0.690 (0.565–0.844) obesity, 0.647 (0.500–0.837) low HDL-c.Conclusion: The practice of sports in youth and current physical activity is a protective factor against the trajectory of obesity and low HDL-c, mainly in female workers. Programs to encourage the practice of physical activity should be carried out in order to reduce cardiovascular risk factors and prevent chronic diseases in workers.

An Eliasian analysis of students’ views on guidelines against sexual harassment and abuse in sport

This article explores an important measure in current prevention policies in sport: guidelines against sexual harassment and abuse. Because little is known about how people involved in sport understand and relate to such guidelines, it fills a gap in current research on sexual harassment and abuse prevention in sport. We draw on ‘video elicitation’ focus group interviews with sport students in Norway. Our analysis is guided by Norbert Elias's sociology of knowledge and particularly his concept of ‘degrees of involvement and detachment’. First, we found that the students had limited knowledge about the sexual harassment and abuse guidelines. Second, we saw how their discussions alternated between different positions when reflecting upon the guidelines’ usefulness. From a relatively detached position, the students supported the general idea of guidelines. From the more involved position they voiced concern related to conduct regulations that conflicted with valued aspects of sport practice and mentioned problematic aspects of sport culture that the guidelines do not target. In a blend of involvement and detachment, the students drew on their sport experiences to reflect critically on both the potentials and limitations of the sexual harassment and abuse guidelines. Finally, we draw some implications of the analysis for the improvement of prevention work.

Influence of Gender Stereotypes, Type of Sport Watched and Close Environment on Adolescent Sport Practice According to Gender

The practice of sport by adolescents is influenced by multiple factors, which could create differences in sports participation according to gender. The objectives of this study were to determine which types of sports were most practiced by adolescent males and females; and to analyze the relationship of gender stereotypes, the type of sport observed and the personal environment, to the type of sport practiced, depending on the adolescent’s gender. To this end, a total of 632 adolescents completed the questionnaire “Lifestyle in Sport with a Gender Perspective”. The results showed significant differences according to gender in the type of sport practiced (p < 0.05), in the membership to sports clubs (p < 0.001), and in the participation in competitions (p < 0.001). It was found that family (p < 0.005) and friends (p < 0.05) were the social agents that most influenced the choice of the type of sport practiced, and that the type of sport watched live (p < 0.005), and in the media (p < 0.001), was related to gender and the type of sport practiced. In contrast, the gender stereotypes of the adolescents themselves were not related to the practice of sports. In conclusion, the environment closest to the adolescents was related to the type of sport practiced by those adolescents.

Capillaroscopic Evidence of Microvascular Damage in Volleyball Players

Volleyball players experience repetitive stress that involves their hands and, in particular, their fingers. Literature reports that repetitive trauma can lead to local vascular abnormalities, such as reduced capillarization and lower resting blood flow. These anomalies could be related to the presence of dysfunctional endothelium. The aim of this study is to correlate the capillaroscopic findings by nailfold video capillaroscopy (NVC) to volleyball practice in order to early detect possible anomalies and perform an adequate follow-up to avoid damages that could negatively affect sport practice and the players’ health status. In this study, 38 subjects were enrolled, 19 volleyball players and 19 healthy non-players as a comparison group. In almost all the players, we found capillaroscopic alterations of the “aspecific pattern” type without substantial gender differences. We may assume that the repeated traumas involving players’ fingers can negatively modify their microcirculation. Based on these observations, it could be a desirable clinical practice to screen professional volleyball players with NVC in order to implement preventive strategies aimed at protecting the health of athletes.

Sport-related acute myocardial infarction. Contemporary data from IMACS survey

Background Sport-related (SR) acute cardiovascular (CV) events are the main cause of sudden cardiac death in the setting of sport activities. However, data are very scarce regarding onset and follow-up of SR acute myocardial infarction (AMI). Methods From the prospective study IMACS (Infarctus du Myocarde et Arret Cardiaque au cours du Sport) patients admitted for a SR-AMI in our university hospital from April 2018 to March 2020 were included. A 12 months follow-up (FU) was achieved through telephone interview to address CV outcomes and sport practice information. Information was obtained from relatives in case of out of hospital sudden cardiac arrest (OH-SCA). Results Among the 55 patients included, all were male, with median (IQR) age at 62 (55–69) y. Most common sports were cycling (n=21), fitness (n=7), swimming (n=5) and hiking (n=5). The SR-AMI occurred during effort for 39 subjects and during recovery for 16. Most SR-AMI occurred in public area (n=24), at home (n=16), or in a specific sport location (n=14). An Automated External Defibrillator (AED) was available in the SR-AMI location in only 10, but was missing in 43 (unknown for 2). In 1 subject with OH-SCA, cardiopulmonary resuscitation (CPR), initiated by witnesses, using a public AED, was unsuccessful. The 4 other patients with OH-SCA underwent successful CPR. Among the 55 subjects, 4 were vapers, of whom 1 was a dual user, 17 were current tobacco smokers, 18 were ex-smokers and 2 experienced cannabis and cocaine use. Among the smokers, most smoked (n=10) or consumed cannabis (n=1) &lt;2h before the event. Strikingly, CV history and/or recent symptoms were present in almost half (n=25). Only 10 felt symptoms exclusively during the sport session. Moreover, a medical advice for recent symptoms was found only for 3 subjects. Three patients who experienced prior AMI have neglected symptoms during the index event. Most were ST segment elevated MI (n=35). Only one patient (with OH-SCA) died &lt;3 days after hospital admission. During hospitalization, most underwent revascularization with coronary stenting (n=44) (drug eluting stent in 43 patients), or coronary artery bypass graft (n=6) and no death nor significant CV event occurred. At 1-FU, most attended a rehabilitation program (n=41) and the majority of smokers quitted (14/17), with 3 persistent smokers starting to vape. Almost half patients (n=23) decreased their physical activity, and 21 increased it. A significant rate of patient (n=9) added fitness in their usual activity, and as a main sport for 4 of them. Conclusions In this on-going monocentric prospective survey in SR-AMI, a high proportion of subjects had prodromal symptoms, of whom only few led to sport cessation and medical advices, when requested, failed to prevent the AMI. Our findings highlight that public and medical education are urgently warranted for SR-AMI prevention. FUNDunding Acknowledgement Type of funding sources: Public hospital(s).

Effects of the COVID-19 Health Crisis on Sports Practice, Life Quality, and Emotional Status in Spanish High-Performance Athletes

Spain is one of the many countries highly affected by the COVID-19 crisis, establishing very restrictive measures with a complete lockdown for more than 3 months. This situation forced the complete closure of sport practice and national or international competitions, leading to a negative impact on physical and psychological health of high-performance athletes. Therefore, the objectives of this study were (a) to determine the effects of the COVID-19 health crisis on Spanish high-performance athletes in terms of sports practice, life quality, and emotional state and (b) to identify the profile with the greatest difficulties during and after the lockdown. A sample of 130 high-performance athletes aged between 18 and 34 years (67 women and 63 men) participated in this study (83.1% achieved a medal in National–International elite competitions; 86.9% were considered student-athletes). Measures included socio-demographic data through a 5-dimension ad hoc survey: physical activity and exercise using an adapted version from the International Physical Activity Questionnaire (IPAQ); health status and limitations using an adapted version of SF-12 Health Questionnaire; Perceived stress (Short-PSS); and Mood States (29-item POMS). All participants have shown a significant decrease pre–post-lockdown in both health and performance perception, especially in women, individual athletes, medalists, and student-athletes. Strong limitations of training, attention, and motivation as well as a moderate negative emotional state during lockdown were reported, in women, individual athletes, medalists, and student-athletes. Even with an improved emotional state and energy level in the post-lockdown period, moderate-to-high stress scores were reported by women and medalists. Our findings highlight the importance of paying attention to the physical and psychological health of elite athletes on three profiles: team athletes (due to social distance), student-athletes (dual-career issues), and women athletes (prevalence of implicit gender inequalities in sport).
