The Most Demanding Scenarios of Play in Basketball Competition From Elite Under-18 Teams.

ABSTRACT: The main purpose of this study was to describe the most demanding scenarios of match play in basketball through a number of physical demand measures (high-intensity accelerations and decelerations, relative distance covered, and relative distance covered in established speed zones) for four different rolling average time epochs (30, 60, 180, and 300 s) during an official international tournament. A secondary purpose was to identify whether there were significant differences in physical demand measures among playing positions (centers, guards, and forwards) and levels (two best classified teams in the tournament and remaining teams), match scoring (winning, losing, and drawing), and playing periods (match quarter) at the moment of the most demanding scenarios. Data were collected from 94 male under 18 (U18) elite basketball players (age: 17.4 ± 0.7 years; stature: 199.0 ± 11.9 cm; body mass: 87.1 ± 13.1 kg) competing in a Euroleague Basketball Tournament. Measures were compared via a Bayesian inference analysis. The results revealed the presence of position-related differences [Bayesian factor (BF) > 10 (at least strong evidence) and standardized effect size (?) > 0.6 (at least moderate)] so that centers covered a lower relative distance at speed zone 1 and had lower high-intensity accelerations and decelerations than guards. However, the Bayesian analysis did not demonstrate the existence of significant differences in any physical demand measure in relation to the playing level, match scoring, and playing periods at the moment of the most demanding scenarios. Therefore, this study provides coaches and strength and conditioning specialists with a most demanding scenario reference on physical demands that can be used as an upper limit threshold in the training and rehabilitation monitoring processes.

Project description:ObjectiveProfessional Basketball players are at high risk of Achilles tendon rupture. Despite this, there remains limited research into the factors affecting rehabilitation and the long term outcomes of these players. Our aim is to quantify the effect of a player's Achilles tendon rupture on their post-injury performance, and also to explore for correlations between their recovery timeline and pre-injury characteristics. Creation of an injury timeline of past incidents will allow injured players to better track their progress and also inform them about the probable impact on their careers.HypothesisPlayers with Achilles tendon rupture injury will exhibit decreased performance compared to their pre-injury self and their non-injured peers after recovery.MethodsProfessional basketball players who sustained a unilateral Achilles tendon rupture from 1992 to 2016 were collected. 12 players met our inclusion criteria and their Player Efficiency Ratings (PER) were obtained as primary outcome measures; matched controls were chosen based on the PER, Age and playing position. The players' index season PER was compared against the PER during the 10 games immediately following the players' return and the PER of their post-injury peak performing season. The same data analysis was performed against their control group. To investigate the factors affecting the recovery and long-term consequences of their injury, we correlated the variables of Age, BMI, Time of Injury and pre-injury PER with the player's time to return to play and their post-injury PER.Results2 out of 12 players failed to return to playing in the elite professional league following an Achilles Tendon Rupture, others returned after a mean recovery time of 10 months. When compared to players' index PER, the mean PER reduction during the 10 games immediately following the players' return was 7.15 (P < .000). Players on average took 1.8 seasons to reach their post-injury peak performance, with only 1 player returning to his pre-injury performance. Others suffered a mean PER reduction of 3.5 (P = .004) when compared to their index PER and 5.4 (P = .045) against their matched controls.ConclusionAchilles tendon rupture can be a career-ending injury for professional basketball players. They are expected to miss 10 months for rehabilitation and reach their post-injury peak performance level at the 2nd season back. The post-injury peak performance is significantly worse than the pre-injury level, but is similar to matched non-injured players.

Project description:Interventions: Group 1: The Remote Assist application allows discussion or collaboration in teams with a shared view of a patient-specific case. A post-market follow-up (PMCF) observation will confirm the safety as well as an acceptable benefit/risk ratio of the tool in different scenarios. Instead of the telephone or other means of communication, remote assist via VSI HoloMedicine of the MS Team tool will be used in three different scenarios. The following scenarios are evaluated: Adding to the operating room (Whipple) (n=3), indication discussion with collegium (n=3), and emergency department support (ileus, cholelithiasis, appendicitis). The purpose of this qualitative study is to evaluate the teams use of VSI HoloMedicine, in the context of surgery, physician on-call, and the emergency department for the following purposes. Evaluate: Confirm the performance of the teams integration of VSI HoloMedicine (remote assist / 3D hologram / streaming / voice quality). Deployment in different scenarios (OR / emergency / on-call) in terms of remote collaboration. Evaluation of usability, advantages and disadvantages Confirmation of the safety of the medical device Satisfaction of the users Observation of any unforeseen risks related to the function, Ensuring continued acceptance of the risk-benefit ratio. Measurement of mental workload (NASA-TLX). Primary outcome(s): The Remote Assist application enables discussion or collaboration in teams with a shared view of a patient-specific case. A post-market follow-up (PMCF) observation will confirm the safety as well as an acceptable benefit/risk ratio of the tool in different scenarios. Instead of the telephone or other means of communication, remote assist via VSI HoloMedicine of the MS Team tool will be used in three different scenarios. The following scenarios are evaluated: Adding to the operating room (Whipple) (n=3), indication discussion with colleagues (n=3), and emergency support (ileus, cholelithiasis, appendicitis). The aim is long-term post-marketing clinical follow-up (PMCF) of the performance, clinical utility, and safety of the product with respect to MS Teams use of VSI HoloMedicine.
