Tracking Systems in Team Sports: A Narrative Review of Applications of the Data and Sport Specific Analysis.

Seeking to obtain a competitive advantage and manage the risk of injury, team sport organisations are investing in tracking systems that can quantify training and competition characteristics. It is expected that such information can support objective decision-making for the prescription and manipulation of training load. This narrative review aims to summarise, and critically evaluate, different tracking systems and their use within team sports. The selection of systems should be dependent upon the context of the sport and needs careful consideration by practitioners. The selection of metrics requires a critical process to be able to describe, plan, monitor and evaluate training and competition characteristics of each sport. An emerging consideration for tracking systems data is the selection of suitable time analysis, such as temporal durations, peak demands or time series segmentation, whose best use depends on the temporal characteristics of the sport. Finally, examples of characteristics and the application of tracking data across seven popular team sports are presented. Practitioners working in specific team sports are advised to follow a critical thinking process, with a healthy dose of scepticism and awareness of appropriate theoretical frameworks, where possible, when creating new or selecting an existing metric to profile team sport athletes

Professionalism, Golf Coaching and a Master of Science Degree: A commentary

As a point of reference I congratulate Simon Jenkins on tackling the issue of professionalism in coaching. As he points out coaching is not a profession, but this does not mean that coaching would not benefit from going through a professionalization process. As things stand I find that the stimulus article unpacks some critically important issues of professionalism, broadly within the context of golf coaching. However, I am not sure enough is made of understanding what professional (golf) coaching actually is nor how the development of a professional golf coach can be facilitated by a Master of Science Degree (M.Sc.). I will focus my commentary on these two issues

Selecting metrics that matter: comparing the use of the countermovement jump for performance profiling, neuromuscular fatigue monitoring and injury rehabilitation testing

The countermovement jump (CMJ) is one of the most used performance assessments in strength and conditioning. While numerous studies discuss the usability of different metrics in this test, this is often done within the context of a specific aim. However, to our knowledge, no information currently exists providing practitioners with some over-arching recommendations on which metrics to choose when the purpose of using the test differs. This article discusses how the metrics selected to monitor during CMJ testing might differ when aiming to use it as a proxy for athletic performance, as part of neuromuscular fatigue monitoring, or as part of a test battery for return to performance in injured athletes

Estudio Observacional sobre el dolor Postoperatorio leve o moderado: Evaluación del tratamiento con Paracetamol IV. Estudio EOPEP

Objective. Te evalúate the efficacy and safety of post-surgery analgesia with intravenous paracetamol (P-iv). Patient and Methods. Prospective, multicentre-observational study in patients who had surgery associated to mild or modérate postoperative pain (POP) that received 4 doses of P-iv 1 g /4-6h, alone or associated with other analgesics. The degree of pain by the visual analogue scale, effect on the activity, undesirable effects and patient satisfaction were recorded. Period of study: 24 hrs post-surgery. Statistics. Parametric or non-parametric, or a model of regression analysis. Results. 725 patient enrolled, 56% with mild POP and 43,3% modérate POP. EVA decreased significantly through the successive evaluations (p<0,001), but remained below 30. 46,3% received only P-iv as analgesic. Metamizol was the most frequently associated analgesic, followed by opiates. Higher levéis of EVA were correlated with: administration of associated analgesics, more interference with the activity, more nauseas and vomiting and smaller degree of satisfaction (p<0.05). The type of surgery was correlated with greater valúes of EVA. No undesirable effects caused by P-iv were observed. Conclusión. P-iv to 1 g/4-6 h is effective during the 24 first hours post-surgery that produces mild to modérate POP with few undesirable effects, and anaesthesia practice combines frequently P-iv with other analgesics, being the most frequent metamizol followed by opiates.Objetivos. Valorar la eficacia y seguridad de la analgesia postoperatoria con paracetamol intravenoso (P-iv). Pacientes y Métodos. Estudio prospectivo, multicéntrico observacional de pacientes sometidos a cirugía de dolor postoperatorio (DPO) leve y moderado que recibieron 4 dosis de P-iv 1 g /4-6h, solo o asociado con otros analgésicos. Se valoró el grado de dolor mediante la escala analógica visual, la afectación de la actividad, los efectos indeseables y la satisfacción del paciente. Periodo de estudio. 24 horas postoperatorias. Se aplicaron tests paramétricos o no paramétricos, o un modelo de regresión logística. Resultados. 725 pacientes evaluables, 56% con DPO previsiblemente leve y 43.3% DPO moderado. La EVA disminuyó significativamente en cada una de las valoraciones sucesivas (p<0,001), pero se mantuvo inferior a 30. El 46.3% de los pacientes recibieron P-iv como única analgesia. Metamizol fue el fármaco más frecuentemente asociado, seguido de opiáceos. Los niveles más altos de EVA se correlacionaron con la administración de analgésicos asociados, más interferencia con la actividad, más nauseas y vómitos y menor grado de satisfacción (p<0.05). El factor que se correlacionó con mayores valores de EVA fue el tipo de cirugía. No se observaron efectos indeseables relacionados con el P-iv. Conclusión. P-iv a dosis de 1 g/4-6 h es eficaz durante las primeras 24 horas del postoperatorio de cirugía que produce DPO leve a moderado, con pocos efectos indeseables. En la práctica anestésica se combina con frecuencia con otros analgésicos, siendo el más frecuente el metamizol seguido de opiáceos
