Trampolining has become a popular recreational activity, but currently no method exists by which energy expenditure can be indirectly measured while bouncing. Therefore, the aim of this study was to produce a model to measure energy expenditure while bouncing on a trampoline. To achieve this, the study was completed in two stages. First, a model was developed which calculated the energy absorbed by the trampoline for a known weight. This was achieved using drop tests on a trampoline. Second, the efficiency of energy conversion while trampolining was measured. This involved healthy adults bouncing on a trampoline while energy expenditure was recorded using a gas analyser. The combined datasets from the two parts allowed the formation of a model which can predict energy expenditure while bouncing on a trampoline using only the user's weight as an input. This model can now be used with an on-trampoline measurement method to track energy expenditure while jumping, thereby facilitating the use of trampolines for health and fitness.
蹦床运动已成为一项流行的娱乐活动，但目前尚无间接测量弹跳时能量消耗的方法。因此，本研究旨在开发一种测量蹦床运动时能量消耗的模型。为此，该研究分两个阶段完成。首先，使用蹦床跌落测试开发了一种计算已知重量的蹦床吸收能量的模型。其次，测量了蹦床运动时的能量转换效率。这涉及健康成年人在蹦床上跳跃，同时使用气体分析仪记录能量消耗。两个部分的综合数据集允许形成一个模型，该模型仅使用用户的体重作为输入即可预测在蹦床上跳跃时的能量消耗。现在可以使用一种在蹦床上进行的测量方法来跟踪跳跃时的能量消耗，从而促进了使用蹦床进行健康和健身。
