EMG Activity of the Biceps and Triceps Brachii During Basketball Chest Pass and Reception: Group Differences Based on Age, Experience, and Limb Dominance
Publication . Amaro, Catarina M.; Castro, Maria António; Amaro, Ana M.
Understanding muscle activation patterns during sport-specific skills is essential for optimizing performance and training strategies. In basketball, upper limb actions such as passing and receiving require precise coordination and effective neuromuscular control. The main goal of this study was to analyze and compare the muscle activity of the biceps brachii and triceps brachii during the execution and reception of the two-handed chest pass in basketball players with different levels of competitive experience. Surface electromyography (EMG) data were collected from 14 federated athletes, aged between 11 and 29 years, using the BioSignal Plux system. Participants were allocated into two groups according to their playing experience. Muscle activation was analysed in terms of activation time (AT) and percentage of muscle activation (%MA), normalised to maximum voluntary contraction (MVC). A linear mixed model was used to evaluate the effects of experience level, limb dominance, and their interaction while accounting for repeated measures within participants. No significant differences were observed between dominant and non-dominant limbs for any variable. Significant differences between experience/ age groups were identified mainly in the triceps brachii, particularly for activation time in the lateral head and %MA in the long head. In general, more experienced/aged athletes demonstrated higher levels of neuromuscular activation and shorter activation times, suggesting different motor control strategies. A significant positive association was found between years of practice and %MA of the long head of the triceps brachii. These findings provide novel insights into neuromuscular recruitment during both the execution and reception phases of the basketball chest pass and may inform training strategies aimed at enhancing technical efficiency across developmental stages.
Factors Promoting and Threatening Hope Among Adolescents and Young People Living With HIV in Brazil: A Qualitative Study

The objective of our study was to explore the factors that promote and threaten hope among adolescents and young adults (AYA) living with HIV from northwestern Paraná, Brazil. A qualitative study was conducted with 22 AYA living with HIV receiving care at the Specialized Care Service located in the Paraná region (Brazil). Data were collected between September and November 2024 through semi-structured interviews based on an adaptation of the Mutual Aid Intervention Model for Promoting Hope. Two categories emerged from the data analysis: (a) “I have a strong will to live, I have a lot to live for”: factors that promote hope; (b) “Society’s prejudice and my own”: factors that threaten hope. Factors that promote hope generate motivation, self-confidence, trust, strength, tranquility, and optimism. Those that threaten hope generate insecurity, anxiety, sadness, shame, guilt, and fear. Therefore, health care professionals should look for strategies to promote hope and thereby increase mental health for AYA living with HIV.
