Análisis descriptivo y comparativo de los goles conseguidos tras saques de esquina en la liga española 1ª división: temporadas 2015 y 2019 / Descriptive and comparative analysis of the goals achieved after corner kicks in the Spanish league 1st division: 2015 and 2019 seasons / Análise descritiva e comparativa dos gols marcados após escanteios na 1ª divisão do liga espanhola: temporadas de 2015 e 2019

El objetivo del estudio fue describir de manera exhaustiva la manera de obtener goles tras saque de esquina para analizar la existencia de diferencias, entre las temporadas 2014/15 y 2018/19 en la Liga de Primera División española. El estudio pretendió analizar la incidencia real de esta acción del juego e identificar qué variables están asociadas a la eficacia de la acción al analizar todos los saques de esquina que acaban en gol en dichas temporadas. Para ello se construyó una herramienta de registro en la que se incluyeron criterios contextuales y criterios relacionados con el desarrollo de la acción de gol. Como conclusión, los resultados evidencian una estimación de la tendencia hacia un predominio de los saques de esquina directos o de primera acción (2014/15) hacia saques de esquina de segundas acciones (2018/19). Se observó un incremento del número de jugadores que actúan y una pérdida del predominio del remate de cabeza como acción finalizadora. (AU)

The objectives of the study were to exhaustively describe the way of scoring goals after corner kicks in order to analyze the existence of differences, between the 2014/15 (n = 112) and 2018/19 (n = 90) seasons, in the Liga de Spanish First Division. The study aimed to analyze the real incidence of this game action and identify which variables are associated with the effectiveness of the action by analyzing all the SDE actions thatend in a goal in those seasons. As a main conclusion, the results could show a certain evolution of the predominance of direct or first-action corner kicks (2014/15) towards second or third-action corner kicks (2018/19). Increased the number of players involved in the action and a loss of the dominance of the header as a finishing action, probably related to the change in trend from direct corner kicks (2014/15) towardssecond-action corner kicks or rebounds (2018/19).

Os objetivos do estudo foram descrever exaustivamente a forma de marcar golos após pontapés de canto, de forma a analisar a existência de diferenças, entre as épocas 2014/15 (n=112) e 2018/19 (n=90), na primeira Liga Espanhola. O estudo teve como objetivo analisar a real incidência dessa ação no jogo e identificar quais variáveis que estão associadas à efetividade da ação analisando todas as ações da SDE que terminam em golos nessas temporadas. Como principal conclusão, os resultados puderam evidenciar uma certa evolução da predominância dos pontapés de canto diretos ou de primeira ação (2014/15) para os pontapés de canto de segunda ação (2018/19). Verificou-se ainda um aumento do número de jogadores envolvidos na ação e perdado domínio do cabeceamento como ação de finalização, provavelmente relacionado à mudança na tendência do canto direto (2014/15) para cantos ou ressaltos de segunda ação (2018/19).

Physiological Responses at 15 Minutes of Recovery after a Session of Functional Fitness Training in Well-Trained Athletes.

BACKGROUND: the aim of this study was to analyse muscle fatigue and metabolic stress at 15 min of recovery after performing two independent sessions of functional fitness training (FFT): a session of strength functional fitness training (FFTstrength) and a session of endurance functional fitness training (FFTendurance). METHODS: eighteen well-trained men conducted two protocols, separated by one week of rest: FFTstrength (3 sets of 21, 15 and 9 repetitions of Thruster with bar + Pull ups) and FFTendurance (3 sets × (30 kcal rowing + 15 kcal assault air bike)). Neuromuscular fatigue and metabolic stress were measured right before, right after and at 10 and 15 min after completing the FFT workout, as well as the mean heart rate (HRmean) and the rating of perceived exertion (RPE) at the end of the FFT. RESULTS: FFTendurance recovered the velocity loss values after 15 min of recovery. On the other hand, FFTstrength only recovered velocity in the 1 m·s-1 Tests in squat (SQ), since the velocity levels were 7% lower in the 1 m·s-1 Tests in military press exercise (MP) after 15 min. CONCLUSIONS: These data indicate that there are specific recovery patterns not only as a function of the exercise and the body regions involved, but also regarding the recovery of neuromuscular and metabolic factors, since both FFT workouts obtained high blood lactate concentrations.

Psychological States and Training Habits during the COVID-19 Pandemic Lockdown in Spanish Basketball Athletes.

The outbreak of the COVID-19 pandemic and the resulting restrictions designed to slow the spread of infection greatly disrupted people's lives. The present study aimed to investigate the impact of lockdown on the psychology, training, and sleep habits of a cohort of basketball players. An online survey involving 169 professional and amateur athletes was conducted using four validated psychological questionnaires (WLEIS-S, POMS, BRS, SMS-II) and a Likert scale to measure the rating of perceived exertion (RPE) and training variables. Gender differences in fatigue (p = 0.022); friendships (p = 0.017); others' emotional appraisal (p < 0.001); and resilience (p = 0.031) were apparent, with higher values for women in all categories bar resilience. Comparisons before and during the lockdown revealed that all participants reduced their RPE (p < 0.001); training days (p = 0.004); and training hours (p < 0.001), and experienced a decline in the quality of sleep (p < 0.001). Sleep hours (p < 0.001) increased during lockdown. The professionals and females maintained their training days (p > 0.05), while the non-professionals and males did not. Psychological states during lockdown were a predictor of the differences in training and recovery variables. In situations where training and competition are limited, it is important to develop plans to maintain physical activity, good quality sleep, and promote greater emotional management and understanding to control negative moods.

Injury Prevalence of the Lower Limbs in Handball Players: A Systematic Review.

Lower limb injuries are frequent in handball and a serious hindrance to athletic performance. The aim of this systematic review was to synthesize the available research on the prevalence of lower limb injuries in handball players according to sex and competitive level. According to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis, 19 studies were selected after a systematic search and selection process of three digital databases: Scopus, PubMed, and Web of Science. Furthermore, a study quality analysis using an 'Extension for Sports Injury and Illness Surveillance of the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE-SIIS)' was carried out. The sample consisted of 7110 male and female handball players registering 4483 injuries in their lower limbs. The results showed a high incidence of knee injuries (30.23%) and ankle injuries (24.80%), especially in the ligaments, such as the talofibular and the anterior cruciate ligaments. Considering sex and competitive level, knee injuries accounted for 47.02% of injuries among women, while among men, ankle injuries were most prevalent (34.22%) in international competitions. Additionally, the most common cause of injuries was trauma (85.61%). The findings highlighted that the prevalence of lower limb injuries varies greatly according to the characteristics of the sample and injury. Therefore, the study underlines the importance that sports practitioners (physical trainers, readapters, and physiotherapists) adapt training protocols to reduce injury incidence in the most affected body areas or tissues.
