Visor use among National Hockey League players and its relationship to on-ice performance

Objective To assess the use of half and three-quarter visors among National Hockey League (NHL) players and investigate the relationship between skill level and on-ice statistics such as points, penalty minutes and ice time and visor use. Design All players who played at least one game during the 2014-2015 NHL season were included in the study. Visor usage including three-quarter visor use was determined using official in-game images and video. Player information and statistics were obtained from a statistical hockey database. A multiple logistic regression model was used to study how the different player statistics influenced the probability of a player wearing a visor. Results Visor use was 87.1% among all NHL players (N=881) and 81.7% among all non-rookie players (N=612). Players who wore a visor were on average younger, played more games during the season, had more points, goals, assists and received more playing time. Players who did not wear a visor had 3 times more penalty minutes for every 100min played. Only 11 (1.2%) players wore a three-quarter visor and these players were much older and contributed more to their team's offence when compared with the players who wore a one-half visor. Conclusions Visor usage in the NHL continues to increase independent of new legislation making it mandatory for rookie players to wear a visor. Based on the results and the logistic regression model built in the study, those players who have the highest risk for not wearing a visor can be identified to help establish targeted interventions.
