(1) Background: The subject of athlete burnout is often discussed among sports psychologists. Interventions to reduce this phenomenon are still under investigation with follow-ups. Thus, the purpose of the current meta-analysis is to examine psychological interventions that was carried out to decrease or eliminate burnout syndrome in young athletes. (2) Methods: Scientific electronic databases were searched, and five published studies published between January and June 2022 that met the criteria were selected. The systematic review and meta-analyses followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The Cochrane collaboration tool for assessing the risk of bias was used to assess the studies’ quality. Metafor, a package of the R statistical program, was used to perform the analysis. (3) Results: Cognitive behavioral therapy- and mindfulness-based interventions effectively reduced most dimensions of burnout. Moreover, online interventions were significantly more beneficial in this reduction. (4) Conclusions: There should be more high-quality studies on the effectiveness of psychological interventions in reducing burnout, mainly because it leads to tremendous physical and psychological problems for athletes and their coaches; therefore, it requires particular interventions and prevention strategies.

The aim was to compare pacing, biomechanical and perceptual responses between elite speed-and endurance-adapted milers during a sprint interval training session (SIT). Twenty elite and world-class middle-distance runners (male: n = 16, female: n = 4; 24.95 ± 5.18 years; 60.89 ± 7 kg) were classified as either speed- or endurance-adapted milers according to their recent performances at 800 m or longer races than 1500 m (10 subjects per group). Participants performed 10 repetitions of 100 m sprints with 2 min of active recovery between each, and performance, perceptual and biomechanical responses were collected. The difference between accumulated times of the last and the first five repetitions was higher in speed-adapted milers (ES = 1.07) displaying a more positive pacing strategy. A higher coefficient of variation (CV%) was displayed across the session by speed-adapted milers in average repetition time, contact time, and affective valence (ES ≥ 1.15). Speed-adapted milers experienced lower rates of valence after the 4th repetition excepting at the 8th repetition (ES ≥ 0.99). Speed-adapted milers may need to display a more positive pacing profile than endurance-adapted milers and, therefore, would experience lower levels of affective valence and a more rapid increase of ground contact time during a SIT.

ResumenEl objetivo de este estudio fue crear un listado de situaciones de estrés pre y durante partido, basándonos en la experiencia personal de 59 árbitros de la liga LEB durante un Clinic de árbitros del grupo I de la Asociación Española de Árbitros de Baloncesto y la Federación Española de dicho deporte. El Listado de Situaciones Estresantes para el Arbitraje (LISEA) evalúa no sólo la intensidad de la experiencia emocional, sino también la direccionalidad de la misma-El instrumento mostró una alta fiabilidad general (.897). Los resultados ponen de manifiesto que dichas fuentes influyen de forma significativa y diferente según el momento competitivo, siendo más estresante durante el partido menos en un item. Igualmente se observan correlaciones entre la experiencia arbitral en el nivel I y diferentes situaciones evaluadas, siendo más numerosas las correlaciones negativas. La intervención psicológica debería tener en cuenta especialmente estos hallazgos sobre las fuentes de más impacto y en el momento competitivo en que tienen mayor influencia. Palabras clave: estado emocional, estrés, árbitros de baloncesto. ABSTRACT The objective of this study was to draw up a list of stress related situations both before and during the game, based on the experience of 59 LEB League referees who participated in a Clinic for Group 1 of the Spanish Association of Basketball Referees and the Spanish Basketball Federation. The List of Stress related situations for Referees (LISEA) not only assesses the emotional experience but also the directional consequences of stress. The survey showed a very high accuracy value (.897) Results show that different stress sources have a varying influence depending on the moment in the competition, being most stressful during the game except for one item. At the same time, there is a correlation between the refereeing experience at level 1 and different situations assessed, with negative correlations being most common. Psychological intervention should bear in mind these findings in relation to the stress sources with highest impact and the competitive moment during which they exert most influence.
