The aim of the study was to assess the validity and reliability of wearable body metric Hexoskin "smart shirt" in measuring heart rate (HR) at pre-exercise and during peak effort in a field test incorporating vigorous movements of the upper body. Measurements were recorded simultaneously using the Hexoskin and Polar Team Pro. Nine male professional handball players (age: 21.8 ± 2.4 years; weight: 83 ± 10.26 kg; height: 1.81 ± 0.09 m; and BMI: 25.17 ± 2.23) volitionally participated in the study by completing two 400 m shuttle run test trials (10 shuttles), each separated by a 48 to 72 h recovery period. Results indicated significant correlations between Hexoskin and Polar Team Pro system in pre-exercise HR. Hexoskin provided erroneous measurements in four of the nine athletes during peak effort. Subsequent correction yielded no consistency between the Polar Team Pro system and Hexoskin between the first and the second trial. Hexoskin showed significant reliability in pre-exercise HR. However, Hexoskin picked up excessive artifact during vigorous physical activity in four of the nine athletes rendering the results in these cases useless. Nevertheless, in athletes where artifact was not an issue, ICC yielded a good estimate. The main findings indicate that Hexoskin has good validity and reliability in measuring pre-exercise HR in handball players and hence may be used with high confidence in slow motion activities. However, vigorous physical activity with jarring multidirectional upper body movements posed a challenge for Hexoskin.
本研究的目的是评估可穿戴身体测量设备Hexoskin“智能衬衫”在一项包含上半身剧烈运动的现场测试中，于运动前和运动峰值时测量心率（HR）的有效性和可靠性。使用Hexoskin和Polar Team Pro同时记录测量数据。九名男性职业手球运动员（年龄：21.8±2.4岁；体重：83±10.26千克；身高：1.81±0.09米；体重指数：25.17±2.23）自愿参与研究，完成两次400米穿梭跑测试（10趟），每次测试间隔48至72小时的恢复期。结果表明，Hexoskin与Polar Team Pro系统在运动前心率方面存在显著相关性。在运动峰值时，九名运动员中有四名运动员的Hexoskin测量结果出现错误。随后的校正显示，第一次和第二次测试之间，Polar Team Pro系统与Hexoskin之间没有一致性。Hexoskin在运动前心率测量方面显示出显著的可靠性。然而，九名运动员中有四名在剧烈体育活动期间出现过多伪影，导致这些情况下的结果无用。尽管如此，在没有伪影问题的运动员中，组内相关系数（ICC）给出了良好的估计。主要研究结果表明，Hexoskin在测量手球运动员运动前心率方面具有良好的有效性和可靠性，因此在慢动作活动中可以高度自信地使用。然而，上半身剧烈的多方向震动运动对Hexoskin构成了挑战。
