Influence of Adventure Race Disciplines on the Overall Performance during 35 to 50-km Races

Abstract Aims: This study aims to analyze the influence of adventure race disciplines on the overall performance during 35 to 50-km competitions. Methods: Twenty-four athletes from twelve teams were studied during the second (Jacarei-SP, Brazil, 44.5-km) and fourth (Passa Quatro-MG, Brazil, 37.1-km) races of the 2015 Haka Race Series, which comprised Brazilian Adventure Race Ranking. We analysed the relationship between disciplines velocities and overall race velocity of the teams during each competition. Results: We observed the race velocity of the teams during second race was significantly (P < 0.05) correlated with the first (R=0.80) and last (R=0.65) split velocities of trekking, and with the last split velocity of mountain biking (R=0.73). On the other hand, the race velocity of teams during fourth race was significantly (P < 0.05) correlated with the split velocity performed during the course of water trekking with trekking (R=0.96). Conclusion: Greater performance of the athletes in the disciplines of mountain biking, trekking and water trekking is related to their overall performance during 35-50 km ARs. In addition, the influence of adventure race disciplines is specific to the overall performance during different competitions.

摘要 研究目的：本研究旨在分析探险越野赛（Adventure Race）各项目对35至50公里赛事总成绩的影响。
研究方法：本研究选取纳入巴西探险越野赛排名体系的2015年哈卡探险越野赛系列赛（Haka Race Series）的第二站与第四站作为研究场景，其中第二站赛事举办于巴西圣保罗州雅卡雷伊，赛程44.5公里，第四站赛事举办于巴西米纳斯吉拉斯州帕萨夸特鲁，赛程37.1公里；本研究对来自12支队伍的24名运动员进行数据分析，并分析了各赛事中各项目的分段行进速度与队伍总行进速度之间的关联。
研究结果：第二站赛事中，队伍的总行进速度与徒步（trekking）项目的首段（R=0.80）及末段（R=0.65）分段速度，以及山地自行车（mountain biking）项目的末段分段速度（R=0.73）均呈显著相关（P < 0.05）。另一方面，第四站赛事中，队伍的总行进速度与涉水徒步（water trekking）与徒步组合项目的分段速度呈显著相关（P < 0.05，R=0.96）。
研究结论：运动员在山地自行车、徒步及涉水徒步项目中的表现越好，与其在35至50公里探险越野赛中的总成绩呈正相关。此外，探险越野赛各项目对总成绩的影响因赛事不同而存在特异性。
