The energy expenditure and heart rate of five Shetland ponies were measured during transport and compared with the values recorded while they were at rest and walking. Secondary aims of the study were to investigate whether there was any correlation between heart rate and energy expenditure and whether different orientations affected the values to different degrees. The measurements were recorded at one-minute intervals while the ponies were at rest, walking and being transported in four different orientations, on journeys lasting 30 minutes. There were significant increases (P < 0.001) in both heart rate and energy expenditure during transport which were similar to those associated with walking, and there was a strong correlation between the two measurements. There was no conclusive evidence that orientation affected the measurements, but it appeared that rear facing transport might have had the least effect.
在运输过程中测量了5匹设得兰矮种马的能量消耗和心率，并将其与它们在休息和行走时记录的值进行比较。该研究的次要目的是调查心率与能量消耗之间是否存在任何相关性，以及不同的朝向是否会对这些值产生不同程度的影响。在持续30分钟的行程中，当矮种马处于休息、行走以及以四种不同朝向运输时，每隔一分钟记录一次测量值。运输过程中心率和能量消耗均显著增加（P < 0.001），这与行走时的情况相似，并且这两项测量之间存在很强的相关性。没有确凿证据表明朝向会影响测量值，但似乎向后运输可能影响最小。
