背景资料：地面硬度被认为是与橄榄球伤害相关的可能的危险因素之一。目的：研究地面硬度、降雨量和蒸散量对伤害发生率的贡献，并调查橄榄球联盟整个赛季的季节性伤害偏差。方法：对271名参加特级橄榄球比赛的橄榄球队运动员进行了前瞻性的流行病学调查在新西兰的达尼丁。每场比赛前，使用工业透度计测量地面硬度超过20轮，并通过国家天气和大气研究所和奥塔哥地区理事会收集当地天气信息。泊松混合模型被用来描述受伤的发病率作为地面硬度的函数在整个season.Results：在本赛季的整体受伤的发病率为52受伤每1000比赛球员小时（95%CI 42至65）。虽然受伤率随比赛轮数的增加而逐渐下降，其比率为0.98（95%CI 0.96 - 0.99）（p = 0.036），且比赛场地的硬度随赛季的增加而显著下降（0.16 MPa/轮，95%CI 0.12 - 0.21，p
Background: Ground hardness is considered one of the possible risk factors associated with rugby injuries.Objectives: To examine the contribution of ground hardness, rainfall and evapotranspiration to the incidence of injury, and to investigate seasonal injury bias throughout one full season of rugby union.Methods: A prospective epidemiological study of rugby injuries was performed on 271 players from rugby union teams involved in the premier grade rugby competition in Dunedin, New Zealand. Ground hardness was measured before each match over 20 rounds with an industrial penetrometer, and local weather information was collected through the National Institute of Weather and Atmospheric Research and the Otago Regional Council. Poisson mixed models were used to describe injury incidence as a function of ground hardness throughout the season.Results: The overall injury incidence during the season was 52 injuries per 1000 match player-hours ( 95% Cl 42 to 65). Although injury incidence decreased gradually by round with a rate ratio of 0.98 ( 95% Cl 0.96 to 0.99) ( p = 0.036), and the hardness of match grounds decreased significantly over the season ( 0.16 MPa/ round, 95% Cl 0.12 to 0.21, p
