论文代写:运动前后心率差异

该图显示了运动前后BMI与心率差异的相关性。 BMI显示在y轴上,x轴上显示心率差异。可以观察到,每分钟心跳的许多差异聚集在15-20-25的BMI周围并且变得更小。因此,心率差异在某些BMI范围内较高,并且在BMI高于25时变小,在30和以上范围内观察到少量散点图。与甚至25-30和以上的BMI范围相比,20-25个BMI范围在心率上也有更多的差异。这表明BMI可能对运动前后的心率差异没有如此显着的影响。因此,假设BMI增加导致运动前后心率差异增加不一定是真实的。结果也有可能出现偏差的可能性很大;这是因为有些参与者没有填写数据。另外,它们大部分都只属于某些BMI范围,因此很难理解不同范围的数据。

The chart shows the correlation of the BMI and the heart rate differences before and after exercise. The BMI is presented on the y axis and the heart rate difference on the x axis. It can be observed that much of the differences of heart beat per minute is clustered around the BMI of 15-20-25 and become less. The heart rate difference is hence higher within certain BMI ranges and becomes less when the BMI goes above 25, with few scatters observed in the 30 and above range. Also 20-25 BMI ranges have more difference in heart rate, compared to even the 25-30 and above BMI ranges. This shows that BMI might not have such a significant effect on the heart rate difference before and after exercise. Therefore, hypothesis that the increase in BMI results in increase in the difference in heart rate before and after exercise need not be true. There are good chances that the results might be skewed as well; this is because some participants had not filled in data. Additionally, most of them fell into only certain BMI ranges and hence it was difficult to understand data across different ranges.
