To evaluate if the Hexoskin smart shirt (HxS) would produce valid and reliable measurements for heart rate (HR), respiratory rate (RR), minute ventilation (V), step count (SC), and energy expenditure (EE) when compared to a Polar T-31 heart rate monitor, an Applied Electrochemistry Moxus Metabolic System, and a manual step count. A two-day walking treadmill protocol with participants walking for 3 minutes at 3 speeds (1.5mph, 2.5mph, 3.5mph, 0% grade) was performed. Forty-nine volunteers participated the first day, forty-six on the second, thirty-one were used for reliability. Values calculated for the HxS data used Pearson's product-moment correlation (p < 0.05; r ≥ 0.70) for validity and Cronbach's α (≥ 0.70) for reliability. HxS HR (1.5mph; p<0.01, r=0.86, α=0.86. 2.5mph; p<0.01, r=0.81, α=0.88. 3.5mph; p<0.01, r=0.85, α=0.85), HxS RR (1.5mph; p<0.01, r=0.87, α=0.93. 2.5mph; p<0.01, r=0.86, α=0.92. 3.5mph; p<0.01, r=0.71, α=0.76), HxS V (1.5mph; p=0.66, r=0.11, α=0.70. 2.5mph; p=0.01, r=0.15, α=0.73. 3.5mph; p=0.31, r=0.08, α=0.14), HxS SC (1.5mph; p=0.90, r=-0.01, α=0.70. 2.5mph; p=0.22, r=0.13, α=0.86. 3.5mph; p<0.01, r=0.74, α=0.85), HxS EE (1.5mph; p<0.01, r=0.56, α=0.85. 2.5mph; p<0.01, r=0.50, α=0.83. 3.5mph; p<0.01, r=0.51, α=0.80). HxS HR and RR provided valid and reliable measures at all three speeds while V, SC, and EE had a mixture of results based on speed. These results are important in the use of the Hexoskin in an accurate manner for athletes, coaches, and for the potential medical applications being advocated in the field of telemedicine procedures.
为评估与极地T - 31心率监测仪、应用电化学Moxus代谢系统和手动步数计数相比，Hexoskin智能衬衫（HxS）是否能对心率（HR）、呼吸频率（RR）、分钟通气量（V）、步数计数（SC）和能量消耗（EE）产生有效且可靠的测量结果。进行了一项为期两天的跑步机步行试验，参与者以三种速度（1.5英里/小时、2.5英里/小时、3.5英里/小时，坡度为0%）各步行3分钟。第一天有49名志愿者参与，第二天有46名，31名用于可靠性分析。针对HxS数据计算的值，有效性采用皮尔逊积矩相关性（p < 0.05；r≥0.70），可靠性采用克朗巴哈α系数（≥0.70）。HxS心率（1.5英里/小时；p<0.01，r = 0.86，α = 0.86。2.5英里/小时；p<0.01，r = 0.81，α = 0.88。3.5英里/小时；p<0.01，r = 0.85，α = 0.85），HxS呼吸频率（1.5英里/小时；p<0.01，r = 0.87，α = 0.93。2.5英里/小时；p<0.01，r = 0.86，α = 0.92。3.5英里/小时；p<0.01，r = 0.71，α = 0.76），HxS分钟通气量（1.5英里/小时；p = 0.66，r = 0.11，α = 0.70。2.5英里/小时；p = 0.01，r = 0.15，α = 0.73。3.5英里/小时；p = 0.31，r = 0.08，α = 0.14），HxS步数计数（1.5英里/小时；p = 0.90，r = -0.01，α = 0.70。2.5英里/小时；p = 0.22，r = 0.13，α = 0.86。3.5英里/小时；p<0.01，r = 0.74，α = 0.85），HxS能量消耗（1.5英里/小时；p<0.01，r = 0.56，α = 0.85。2.5英里/小时；p<0.01，r = 0.50，α = 0.83。3.5英里/小时；p<0.01，r = 0.51，α = 0.80）。HxS心率和呼吸频率在所有三种速度下都提供了有效且可靠的测量结果，而分钟通气量、步数计数和能量消耗的结果因速度而异。这些结果对于运动员、教练准确使用Hexoskin以及远程医疗程序领域所倡导的潜在医疗应用具有重要意义。
