The Polar A300 fitness watch includes a feature termed the 5-minute fitness test. This feature claims to estimate maximal oxygen consumption (VO2max) in healthy adults. The purpose of this study was to assess the validity and reliability of the Polar A300 "Fitness Test" VO2max estimation feature. Nineteen recreationally active young adult males (n=9) and females (n=10) completed a Bruce protocol treadmill protocol to assess VO2max, followed by two separate 5-minute Polar Fitness Test (VO2max estimation) trials. A Pearson's r test was used to determine the relationship between VO2max from the Bruce Test to each Polar watch VO2max estimate, as well as to a non-exercise VO2max prediction equation. Additionally, a One Way ANOVA assessed differences in absolute group means of the Polar results to the Bruce Test, and non-exercise prediction model. There was a statistically significant, moderate-strong relationship between the Polar and the criterion Bruce VO2max estimations with the first Polar Test (n=19; r=.635; p<.05), as well as the second (n=19; r=.645; p<.05). The average VO2max of the two Polar tests and the Bruce test show greatest positive correlation (n=19; r=0.655; p<0.001). The reliability of the Polar watch indicated significance between the test-retest results (n=19; r=.907; p<.05). Lastly, the positive correlation between the non-exercise predicted model and the Bruce Test was weaker than the polar predictions (n=19; r=.522; p<.05). Preliminary results conclude that the Polar A300 Fitness watch is a valid tool for estimation of VO2max.
博能A300健身手表具有一项名为5分钟健身测试的功能。该功能宣称可估算健康成年人的最大摄氧量（VO2max）。本研究的目的是评估博能A300“健身测试”VO2max估算功能的有效性和可靠性。19名有休闲运动习惯的年轻成年男性（n = 9）和女性（n = 10）完成了一项用于评估VO2max的布鲁斯方案跑步机测试，随后进行了两次独立的5分钟博能健身测试（VO2max估算）试验。使用皮尔逊相关系数r检验来确定布鲁斯测试得出的VO2max与每块博能手表VO2max估算值之间的关系，以及与一个非运动VO2max预测方程之间的关系。此外，单向方差分析评估了博能测试结果与布鲁斯测试以及非运动预测模型的绝对组均值差异。在第一次博能测试（n = 19；r = 0.635；p < 0.05）以及第二次测试（n = 19；r = 0.645；p < 0.05）中，博能测试与标准布鲁斯VO2max估算值之间存在统计学上显著的中度至强相关性。两次博能测试的平均VO2max与布鲁斯测试显示出最大的正相关性（n = 19；r = 0.655；p < 0.001）。博能手表的重测结果显示出可靠性（n = 19；r = 0.907；p < 0.05）。最后，非运动预测模型与布鲁斯测试之间的正相关性弱于博能测试的预测结果（n = 19；r = 0.522；p < 0.05）。初步结果表明，博能A300健身手表是估算VO2max的有效工具。
