Introduction and Goal: Ultimate Frisbee (UF) is a fastgrowing team sport worldwide, but to date, physiological and physical demands of UF have only been addressed on low playing levels (Krustrup & Mohr, 2015; Scanlan et al., 2015). [...]our study assessed cardiovascular loading during an elite UF game and examined the relationship between cardiovascular loading and intermittent running performance (IRP).

Frisbee technique is reflected in the different game actions, such as the multiple types of throws, displacements, sense of direction and types of jumps, which are fundamental in the two main actions of the game: defense and offense. The objective of the present study was to determine the effect of a plyometric training program on jumping ability in ultimate frisbee athletes (18-35 years old) in a sample of Colombian players. The study included 21 ultimate athletes from the municipality of Cajicá elite category, associated in four groups: 18-23 (n=5), 24-27 (n=4), 28-31 (n=6), 32-35 (n=6) with an average age of 27.64±5.10 years, a height 173.09±7.18 cm and a body mass of 70.41±9.47 kg. Quantitative approach study, descriptive type of study and quasi-experimental design. The statistical treatment was carried out using the Python program version 3.7.3. The results indicate that there are improvements in jumping capacity, although these differences are not significant in any of the jumps (SJ, CMJ, CMJB) (p=>0.05), so, when relating the characteristics of the subjects, it is found that age does not represent an important factor in plyometric training on explosive strength. Thus, the variables studied in this research do not seem to be sensitive to an eight-week plyometric training program with an intensity of two weekly sessions to show significant differences in the development of explosive strength in elite category ultimate frisbee players.

The human posteromedial cortex, which includes core regions of the default mode network (DMN), is thought to play an important role in episodic memory. However, the nature and functional role of representations in these brain regions remain unspecified. Nine participants (all female) wore smartphone devices to record episodes from their daily lives for multiple weeks, each night indicating the personally-salient attributes of each episode. Participants then relived their experiences in an fMRI scanner cued by images from their own lives. Representational Similarity Analysis revealed a broad network, including parts of the DMN, that represented personal semantics during autobiographical reminiscence. Within this network, activity in the right precuneus reflected more detailed representations of subjective contents during vivid relative to non-vivid, recollection. Our results suggest a more specific mechanism underlying the phenomenology of vivid autobiographical reminiscence, supported by rich subjective content representations in the precuneus, a hub of the DMN previously implicated in metacognitive evaluations during memory retrieval.

El objetivo de este estudio fue analizar los efectos sobre las tres dimensiones de la Inteligencia Emocional de una intervención del modelo pedagógico de Aprendizaje Cooperativo en Educación Física. Un total de 29 estudiantes de un colegio público de Educación Primaria al sureste de España, con una media de edad de 11.20 (± .41 años), participaron. El instrumento empleado fue el cuestionario Trait-Meta Mood Scale (TMMS), versión reducida, adaptada a la población española por Fernández-Berrocal et al. (2004). El estudio siguió un diseño pre-postest sin grupo control, mediante el desarrollo de una unidad didáctica cooperativa de ocho sesiones basada en el deporte alternativo de Ultimate Frisbee. Los resultados obtenidos arrojan la mejora significativa en las tres dimensiones de la Inteligencia Emocional, además de encontrar un 100% de fidelidad, por parte de dos investigadores externos a la intervención, en la validación de la unidad didáctica de Aprendizaje Cooperativo. Como conclusión principal se destaca la importancia de intervenciones cooperativas en un contexto natural para la mejora de las habilidades emocionales de atención emocional, claridad de sentimientos y reparación emocional de los estudiantes en Educación Primaria en Educación Física.

The aim of this study was to assess the effects on the three Emotional Intelligence dimensions of an intervention of the pedagogical model of Cooperative Learning in Physical Education. A total of 29 students from a public Primary School in the southeast of Spain, with an average age of 11.20 (± .41 years), participated. The instrument used was the Trait-Meta Mood Scale (TMMS), reduced version, adapted to the Spanish population by Fernández-Berrocal et al. (2004). The study followed a pre-post design, without a control group, through the implementation of a cooperative teaching unit of eight sessions using the alternative sport of Ultimate Frisbee. The results showed significant improvement in the three dimensions of Emotional Intelligence, in addition to finding 100% fidelity, by two researchers external to the intervention, in the validation of the Cooperative Learning didactic unit. As a main conclusion, the importance of cooperative interventions in a natural context for the improvement of emotional skills of attention, clarity of feelings and emotional repair of students in Primary Education in Physical Education is highlighted.

(1) Ultimate frisbee involves frequent cutting motions, which have a high risk of anterior cruciate ligament (ACL) injury, especially for female players. This study investigated the in-game cutting maneuvers performed by female ultimate frisbee athletes to understand the movements that could put them at risk of ACL injury. (2) Lower-body kinematics and movement around the field were reconstructed from wearable lower-body inertial sensors worn by 12 female players during 16 league-sanctioned ultimate frisbee games. (3) 422 cuts were identified from speed and direction change criteria. The mean cut had approach speed of 3.4 m/s, approach acceleration of 3.1 m/s2, cut angle of 94 degrees, and ground-contact knee flexion of 34 degrees. Shallow cuts from 30 to 90 degrees were most common. Speed and acceleration did not change based on cut angle. Players on more competitive teams had higher speed and acceleration and reduced knee flexion during cutting. (4) This study demonstrates that a lower-body set of wearable inertial sensors can successfully track an athlete’s motion during real games, producing detailed biomechanical metrics of behavior and performance. These in-game measurements can be used to specify controlled cutting movements in future laboratory studies. These studies should prioritize higher-level players since they may exhibit higher-risk cutting behavior.

Study DesignRetrospective cohort.ObjectivesTo examine the incidence rate and describe the type of ankle injuries in intramural and club sports at the United States Military Academy.BackgroundAnkle injuries are common among athletes and military personnel. However, there is limited epidemiological data for intramural and club sports participation.Methods and MeasuresTen years (academic years 2006–2007 through 2015–2016) of ankle injury data was collected from the Cadet Illness and Injury Tracking System (CIITS) for flag football, team handball, judo, orienteering, rugby, and ultimate Frisbee. The primary outcome of interest was ankle injury incidence rate (IR) with 95% confidence intervals (CI) per 1000 athlete exposures (AEs) across all sports and by individual sport. AEs were defined as one cadet participating in a game or practice. Secondary outcomes included type of ankle injury and time lost (TL).ResultsA total of 276 ankle injuries were documented in CIITS during 283,049 AEs, for an IR of 0.98/1000 AEs (95% CI: 0.86–1.10). By sport, the highest to lowest incidence rates were as follows: rugby (IR=2.29; 95% CI: 1.90–2.73), team handball (IR=1.57; 95% CI: 1.11–2.16), judo (IR=1.09; 95% CI: 0.70–1.61), orienteering (IR=0.76; 95% CI: 0.56–1.01), ultimate Frisbee (IR=0.60; 95% CI: 0.42–0.85), and flag football (IR=0.18; 95% CI: 0.09–0.31). Ankle sprains represented 87.1% of all ankle injuries at a rate of 0.84/1,000 AEs (95% CI: 0.73–0.95) with 20.04±34.89 days lost. The highest IR of ankle sprains were in rugby (IR=1.97; 95% CI: 1.61–2.38) and team handball (IR=1.41; 95% CI: 0.97–1.97). Other injuries included ankle strains (5.1%; TL=3.50±8.43 days), inflammation (3.7%; TL=33.60±73.24 days), fractures (1.9%; TL=105.40±50.60 days), contusions (1.5%; TL=6.25±5.80 days), and dislocations (0.4%; TL=163.00±0.00 days).ConclusionAnkle sprains were the most frequent ankle injury across all six sports with the highest incidence rates in rugby and team handball. Clinical efforts should be targeted toward implementing injury-prevention strategies such as bracing or neuromuscular training.

The best treatment for type II superior labral anterior posterior (SLAP) tears in overhead athletes is not well defined. The purpose of this study was to examine post-surgical outcomes in overhead athletes under the age of 35 who underwent primary biceps tenodesis for an isolated type II SLAP tear. We hypothesized that these patients would have high rates of return to play, as well as recovery of range of motion (ROM) and strength after surgery.  Patients were between the ages of 18 and 35, had a primary isolated type II SLAP tear confirmed on magnetic resonance imaging (MRI), and were injured performing overhead activities. All patients underwent biceps tenodesis using an arthroscopic suprapectoral approach. Patients underwent standard postoperative rehabilitation lasting up to one year. Function and outcomes were measured at baseline, three months, six months, one year, and two years using range of motion, strength testing, and patient-reported outcomes (PROs) (Western Ontario Shoulder Instability Index (WOSI), Kerlan-Jobe Orthopedic Clinic Score (KJOC), American Shoulder and Elbow Surgeons Assessment Form (ASES), and Single Assessment Numeric Evaluation (SANE)).  Five patients were included in the case series. There was consistent improvement at each time point on PROs: WOSI, p=0.01; KJOC, p=0.04; SANE, p=0.02; and ASES, p=0.03. Range of motion increased from baseline to each time point with a significant improvement in forward flexion (p=0.03). In strength testing, there were improvements in all exercises and a significant improvement in abducted external rotation between years 1 and 2 (p<0.01).  This study demonstrated that biceps tenodesis in overhead athletes under the age of 35 provides improved outcomes, ROM, and strength.
