To examine the association between preseason training variables and subsequent in-season performance in an elite Australian football team.
Data from 41 elite male Australian footballers (mean [SD] age = 23.4 [3.1] y, height =188.4 [7.1] cm, and mass = 86.7 [7.9] kg) were collected from 1 Australian Football League (AFL) club. Preseason training data (external load, internal load, fitness testing, and session participation) were collected across the 17-wk preseason phase (6 and 11 wk post-Christmas). Champion Data© Player Rank (CDPR), coaches' ratings, and round 1 selection were used as in-season performance measures. CDPR and coaches' ratings were examined over the entire season, first half of the season, and the first 4 games. Both Pearson and partial (controlling for AFL age) correlations were calculated to assess if any associations existed between preseason training variables and in-season performance measures. A median split was also employed to differentiate between higher- and lower-performing players for each performance measure.
Preseason training activities appeared to have almost no association with performance measured across the entire season and the first half of the season. However, many preseason training variables were significantly linked with performance measured across the first 4 games. Preseason training variables that were measured post-Christmas were the most strongly associated with in-season performance measures. Specifically, total on-field session rating of perceived exertion post-Christmas, a measurement of internal load, displayed the greatest association with performance.
Late preseason training (especially on-field match-specific training) is associated with better performance in the early season.
研究一支澳大利亚精英足球队季前训练变量与随后赛季中的表现之间的关联。
从一家澳大利亚足球联赛（AFL）俱乐部收集了41名精英男性澳大利亚足球运动员的数据（平均[标准差]年龄 = 23.4 [3.1]岁，身高 = 188.4 [7.1]厘米，体重 = 86.7 [7.9]千克）。在为期17周的季前阶段（圣诞节后6周和11周）收集季前训练数据（外部负荷、内部负荷、体能测试和训练课参与情况）。冠军数据公司球员排名（CDPR）、教练评分和第1轮选拔被用作赛季中表现的衡量指标。对整个赛季、赛季上半段和前4场比赛的CDPR和教练评分进行了研究。计算了皮尔逊相关性和偏相关性（控制AFL年龄），以评估季前训练变量与赛季中表现指标之间是否存在关联。还采用中位数分割法区分每个表现指标中表现较好和较差的球员。
季前训练活动似乎与整个赛季和赛季上半段的表现几乎没有关联。然而，许多季前训练变量与前4场比赛的表现显著相关。圣诞节后测量的季前训练变量与赛季中表现指标的关联最为强烈。具体而言，圣诞节后场上训练课的总体主观用力程度评分，即内部负荷的一种测量方法，与表现的关联最大。
季前后期训练（尤其是针对比赛的场上训练）与赛季早期更好的表现相关。
