Predictive modelling of the physical demands during training and competition in professional soccer players

Objectives The present study aimed to predict the cut-off point-values that best differentiate the physical demands of training and competition tasks including friendly matches (FM), small sided games (SSG), large sided games (LSG), mini-goal games (MG) and ball circuit-training (CT) in professional soccer players. Design Experimental randomized controlled trial. Methods Fourteen professional players participated in all tasks with the CT, SSG and MG consisting of 8 repetitions of 4-min game play, interspersed by 2-min of active recovery. The training data were compared to the first 32-min of the LSG and two competitive FM per player. All movement patterns from walking to sprint running were recorded using 10 Hz GPS devices while player perception of exertion was recorded via a visual analogue scale, post-task. Decision tree induction was applied to the dataset to assess the cut-off point-values from four training drills (SSG, LSG, MG, and CT) and FM for every parameter combination. Results Distance covered during jogging (2.3–3.3 m/s; >436 m), number of decelerations (≤730.5) and accelerations (≤663), and maximum velocity reached (>5.48 m/s) characterized the physical demands during competition (FM) with great variability amongst training drills. Conclusion The use of these novel, cut-off points may aid coaches in the design and use of training drills to accurately prepare athletes for soccer competition.Sin financiación4.319 JCR (2020) Q1, 17/88 Sport Sciences1.724 SJR (2020) Q1, 19/288 Orthopedics and Sports MedicineNo data IDR 2019UE

First Spanish series of intestinal transplantation in adult recipients Primera serie nacional de trasplante de intestino en receptores adultos

Background: short-bowel transplantation has experienced a substantial growth worldwide following improved results from the late 1990s on, and its coverage by Medicare. According to the International Registry (1985-2005), a total of 1,292 intestinal trasplants for 1,210 patients in 65 hospitals across 20 countries have been carried out thus far. Objective: to know short-term (6 months) results regarding patient and graft survival from the first Spanish series of intestinal transplants in adult recipients. Material and methods: we present our experience in the assessment of 20 potential candidates to short-bowel transplantation between June 2004 and October 2005. Of these, 10 patients were rejected and 4 were transplanted, which makes up the sample of our study. Results: to this date 5 transplants have been carried out in 4 patients (2 retransplants, 2 desmoid tumors, 1 short bowel syndrome after excision as a result of mesenteric ischemia). Upon study completion and after a mean follow-up of 180 days (range 90-190 days) all recipients are alive, and all grafts but one (75%) are fully operational, with complete digestive autonomy. All patients received induction with alemtuzumab except one, who received thymoglobulin; in all induction was initiated with no steroids. Conclusions: intestinal transplantation represents a therapeutic option that is applicable in our setting and valid for recipients with an indication who have no other feasible alternative to keep their intestinal failure under control
