![]() Coaches often face challenges and constraints that influence their daily practice and the competitive outcome. High performance football coaches play a central role in the coach-athlete-performance relationship ( Lyle, 2002 Mallett and Lara-Bercial, 2016). Particularly in football, in the past few decades, the vocation of sports coaching has continued to develop toward professionalization across the world. Sports coaching is a relatively new professional field in comparison to other professions, such as medicine, law, or teaching ( Mallett and Lara-Bercial, 2016). The present results expose the vulnerability of the coaching context in Brazilian football, potentially highlighting an excessive emphasis on short-term results to mediate club management decisions. There was no substantial variation between novice and experienced coaches’ survival probability. Variation between season on survival estimates per round was substantial (between-season standard deviation = 0.48, 95% credible intervals: 0.25–0.95 corresponding to an inverse logit = 0.62, 95% CI: 0.56–0.72). By mid-season, at round 19, the probability of coaches’ survival was 0.42 (95% CI: 0.32–0.53). Considering variation between 20 seasons, only about 26.3% (95% CI: 18.2–36.1) of the coaches ended a season without being sacked. On average and considering un-pooled observations, the median life of a coach was about 16.5 rounds. ![]() Data were available and extracted from the official website of the Brazilian Football Confederation 1. Coaches were assigned as novice (no previous experience as head coach in the top Brazilian championship) or experienced (with at least some previous experience as head coach in the top Brazilian championship). A total survival of 120 coaches was considered between the seasons of 20, i.e., 20 coaches at the beginning of each season. At the start of each season, the coach from each team was followed, being recorded at the time the event occurred, i.e., the coach being sacked. The data considered 4,560 games from the top professional Brazilian football league (Campeonato Brasileiro Série A) between the 20 seasons. We also considered whether previous coaching experience in the top Brazilian professional football championship would change the probability of coaches’ survival across the season. In this study, we examined the probability of coaches’ survival in the top Brazilian professional football championship considering variation across the competitive seasons between 20, considering a multilevel framework. 2Department of Physical Education, School of Sports, Federal University of Santa Catarina, Florianópolis, Brazil. ![]()
