摘要

背景:患者接受自行车运动员和铁人三项运动员在室内和室外的测试、训练和比赛。然而,室内和室外表现之间的差异仍未得到充分研究。本研究旨在分析自行车运动室内和室外成绩之间的关系。我们研究了训练环境历史(室内与室外)和电子竞技平台的应用对上述关系的影响:43名训练有素的铁人三项运动员进行了室内和室外场地测试,以确定最大冲刺功率(MSP)和功能阈值功率(FTP)。通过重复测量方差分析评估了 FTP 和 MSP 的主效应,以分析室内和室外功率输出的差异。应用了多个协变量,包括训练环境历史和 ZWIFT 电子运动平台的应用。根据室内测试结果对室外 FTP 预测进行了多元线性回归分析:结果:在室内和室外获得的 MSP 和 FTP 没有发现明显差异。然而,在铁人三项运动员的室内和室外力量输出(PO)差异中,观察到个体差异很大。在统计学上,FTP 与训练环境历史(P-1 和 W)以及 FTP 与体重指数(以 W*kg-1 和 W 表示的 FTP 分别为 P=0.042 和 P=0.034)之间存在显著的交互作用。根据室内测试建立的室外 FTP 预测公式具有很高的准确性(完全模型和简单模型的 R2 分别为 0.80 和 0.68):这项研究强调了与训练环境和比赛要求相适应的测试环境的关键作用。FTP时室内和室外PO之间的个体差异很大,这与训练环境历史和体重指数有关。在 MSP 方面没有发现这种相互作用。

Differences between indoor and outdoor field cycling tests in triathletes are associated with training environment history and BMI: analysis and prediction formula.

Background: Patients underwent cyclists and triathletes test, train, and race both indoors and outdoors. However, the differences between indoor and outdoor performance remain understudied. This study aimed to analyze the relationship between indoor and outdoor performance in cycling. We investigated the influence of training environment history (indoor vs. outdoor) and application of e-sport platform on the aforementioned relationship.

Methods: Forty-three well-trained triathletes performed indoor and outdoor field tests to establish maximum sprint power (MSP) and functional threshold power (FTP). The main effects for FTP and MSP were assessed by repeated-measures ANOVA to analyze the differences between power output obtained indoors and outdoors. Multiple covariates, including training environment history and application of ZWIFT e-sport platform, were applied. Multiple linear regression was performed to investigate outdoor FTP prediction based on indoor testing.

Results: No significant differences were found for MSP and FTP obtained indoors and outdoors. However, the high individual variability in the disparity between indoor and outdoor power output (PO) in triathletes was observed. There was a statistically significant interaction between FTP and training environment history (P<0.001 for FTP expressed in W*kg-1 and W) and FTP and BMI (P=0.042 and P=0.034 for FTP expressed in W*kg-1 and W, respectively). The prediction formulas to establish outdoor FTP based on indoor testing had high accuracy (R2 0.80 and 0.68 for full and simple model, respectively).

Conclusions: The study underlines the crucial role of the appropriate testing environment, corresponding to the training environment and racing demands. A high individual variability in the disparity between indoor and outdoor PO at FTP are associated with training environment history and BMI. No such interactions were found for MSP.
