Abstract

The aim of this study was to derive an equation that validly and reliably estimates the VO2 reached in the IPTL, a maximum stress test for lifeguards. From the results obtained in the first part of the research, a multiple linear regression model was identified. A "stepwise" procedure was established as a variable selection method, where the VO2IPTL was selected as the dependent variable and the maximum time reached in the IPTL (s), the percentage of muscle mass (%) and weight of the participant (kg), as independent variables. This procedure generated a regression model where a high correlation was observed between the 3 independent variables and the dependent variable (R = 0.84; p <.01). From this model, an equation could be generated that allows estimating the VO2max reached in the IPTL. The analysis of the results suggested that the IPTL was a valid and reliable test to estimate VO2 simply which would allow, in the long term, analysis of changes in lifeguards physical conditioning.

救生员最大摄氧量的计算公式

本研究的目的是推导出一个方程，有效和可靠地估计在IPTL中达到的VO2，这是救生员的最大压力测试。根据第一部分的研究结果，我们确定了一个多元线性回归模型。建立了“逐步”程序作为变量选择方法，其中选择VO2IPTL为因变量，IPTL达到的最大时间(s)，肌肉质量百分比(%)和参与者体重(kg)为自变量。这一过程产生了一个回归模型，其中3个自变量与因变量之间存在高度相关性(R = 0.84;p < . 01)。从这个模型，可以生成一个方程，可以估计在IPTL中达到的最大摄氧量。对结果的分析表明，IPTL是一种有效和可靠的测试，可以简单地估计VO2，从长远来看，可以分析救生员身体状况的变化。
