    From within two groups of sports practices at Vitória’s beachfront - one of foot volleyball and another of soccer - this paper aims to discuss this sport which is so present in our daily lives. The groups were observed through an ethnographic approach in order to understand the characteristics of the surveyed practices and also to analyze them based on the studies that dealt with the subject and /or reached similar paths to this investigation. Based on the fields and interviews’ description notebooks, it was possible to demonstrate how these groups are organized, their strategy maintenance over time and the relationships between the sport practiced by them and the sport in its institutionalized form. These observations served as the basis to answer the main question of the study: Is it possible to think of sport as something with definite characteristics? It was identified that, if we assume the definitions exposed in some studies, many of the groups’ characteristics from this research will be excluded. Thus it confirms the considerations proposed by other studies that present the sporting universe with increasingly diverse features and assorted possibilities of singular appropriations.

    Since the beginning of the 21st century, many high-performance athletes from Brazilian Artistic Gymnastics have chosen to migrate to the circus after the end of their sports careers. In seeking to understand this phenomenon, the aim of this study was to investigate sports retirement and the career transition of former Brazilian artistic gymnasts to the circus, more specifically, to the Canadian companies Cirque du Soleil and Cavalia. This is a qualitative study, with data collected through semi-structured interviews. The research sample consisted of 12 former gymnasts, over 18 years old, selected through purposive sampling. For data analysis, Thematic Analysis was employed, allowing the identification, organization, analysis, and reporting of patterns within the data through detailed organization and description. Both voluntary and involuntary reasons for retirement were identified, including injuries, being released from clubs, and personal choices. The research also highlighted the complexity of the transition to post-competitive life and the need for adequate support. Many former gymnasts found new opportunities in the circus. The data revealed that intrinsic motivation for joining the circus stemmed from the pursuit of self-fulfillment, learning a new language, the circus lifestyle, leveraging athletic experience, and an appreciation for the arts. Extrinsic motivations included the desire to live abroad, travel opportunities, financial gain, and the influence of close individuals. The transition process to the circus presented challenges that fostered personal and professional growth through more flexible training and increased responsibility as performers. The study emphasizes the importance of ongoing support and evidence-based interventions to ensure the well-being of athletes in their new journeys

    Efeito das estratégias de foco de atenção no equilíbrio e na atividade muscular de praticantes de futebol e corrida
    (Universidade Federal do Espírito Santo, 2025-09-11) Delunardo, Anderson Rodrigues; Co-orientador1; https://orcid.org/; http://lattes.cnpq.br/; Orientador1; https://orcid.org/; http://lattes.cnpq.br/; https://orcid.org/; http://lattes.cnpq.br/; 1º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 2º membro da banca; https://orcid.org/; http://lattes.cnpq.br/
    In a training session, it is common for coaches to provide verbal instructions and commands to their athletes, directing attentional focus to either external (external focus) or internal (internal focus) elements of the performed movement. Enhanced performance when maintaining attention on external elements of movement has been verified in several studies, highlighting the caution coaches must exercise when selecting the content of their instructions. These studies also indicate that external focus strategies are effective in reducing postural sway. Since increased efficiency of postural control may be associated with the optimization of sports movements as well as the reduction of falls and injuries, these results suggest external focus strategies as a useful tool for coaches in different sports. However, different sports practices take place in environments of varying predictability—more unpredictable, such as football, and more predictable, such as running. Combined with the motor characteristics of each modality, these differences may explain the unique postural adaptations and regulations adopted by their practitioners. Nevertheless, the role and effects of attentional focus strategies on postural performance and regulation in these different athlete profiles remain not fully elucidated. Therefore, the aim of this study was to investigate the effects of attentional focus on the efficacy (sway) and efficiency (muscle activity) of postural control in football and running practitioners. These modalities have distinct motor and environmental characteristics, potentially leading to the development of unique postural strategies and regulations. For this purpose, the following methodological procedures were applied in this experimental research: Forty-five young adults (18–40 years) participated, distributed into running (n=15), football (n=15), and control (n=15) groups. Postural control was assessed using a force platform under stable and unstable surfaces, in bipedal and single-leg stances. Electromyographic (EMG) signals were collected from the tibialis anterior, medial gastrocnemius, rectus femoris, and biceps femoris muscles of the non-dominant limb. The experimental conditions were organized into two blocks. In the first block, participants received the instruction “stand as still as possible.” Subsequently, a laser strap was positioned on the ankle, and participants performed the second block under the following conditions: (1) Internal Focus (IF), with the instruction “reduce to the maximum your ankle movements,” (2) External Focus (EF), and (3) External Focus with Feedback (EFF), where the instruction for both was “reduce to the maximum the movements of the laser.” In the latter, the laser movement was visible to the participant. The analyzed variables were: (1) mean velocity of COP displacement (VEL) and mean sway amplitude (MSA) (global analysis), (2) time interval between successive peaks (MT), mean value of the peaks (MP), and mean distance between successive peaks (MD) (structural analysis), (3) relative COP spectral power in the frequency bands 0.0–0.3 Hz, 0.3–1.0 Hz, and 1.0–3.0 Hz (spectral analysis), and (4) Coactivation Index (CI) and Linear Envelope (ENV), descriptors of muscle activity. Greater efficacy of postural control (sway reduction) was observed for external focus strategies, particularly when combined with feedback, compared to internal focus and control conditions. Internal focus also promoted sway reduction compared to the control condition. Structural descriptors indicated more stable and effective postural commands under focus conditions relative to control, with no differences between focus types, while spectral analysis evidenced that attentional direction may modulate the use of sensory information for postural stabilization. However, the effects of external focus on the efficiency (muscle activity) of postural control were heterogeneous, revealing increased activation in some muscles and decreased activation in others, making it difficult to consistently associate external focus strategies with greater efficiency of postural control. Furthermore, most of the betweengroup differences were concentrated in electromyographic activity, suggesting that participants relied on different levels of muscular effort to achieve similar outcomes for sway and postural control dynamics. It is believed that the scarcity of differences (in other descriptors) between modalities limited the detection of more consistent interactions between focus and sport type, which were revealed only for the coactivation index. In conclusion, the results of the present study reinforce the positive effects of external focus on the efficacy and dynamics of postural control. However, the heterogeneous effects of external focus on the efficiency (muscle activity) of postural control suggest caution when associating attentional focus with greater efficiency. Finally, despite the scarcity of significant interactions between group and attentional focus condition for other descriptors, the results found for muscle activity cautiously suggest that the effects of focus may be modulated by sport practice. These findings indicate the possibility of advancing future investigations, including additional analyses and experimental procedures, to better understand the effects of attentional focus on postural control
