Exergames have been recommended as alternative ways to increase the health benefits of physical exercise. However, energy system contributions (phosphagen, glycolytic, and oxidative) of exergames in specific age groups remain unclear. The purpose of this study was to investigate the contributions of three energy systems and metabolic profiles in specific age groups during exergames. Seventy-four healthy males and females participated in this study (older adults, = 26: Age of 75.4 ± 4.4 years, body mass of 59.4 ± 8.7 kg, height of 157.2 ± 8.6 cm; adults, = 24: Age of 27.8 ± 3.3 years, body mass of 73.4 ± 17.8 kg, height of 170.9 ± 11.9 cm; and adolescents, = 24: Age of 14 ± 0.8 years, body mass of 71.3 ± 11.5 kg, height of 173.3 ± 5.2 cm). To evaluate the demands of different energy systems, all participants engaged in exergames named Action-Racing. Exergames protocol comprised whole-body exercises such as standing, sitting, stopping, jumping, and arm swinging. During exergames, mean heart rate (HR), peak heart rate (HR), mean oxygen uptake (VO), peak oxygen uptake (VO), peak lactate (Peak La), difference in lactate (ΔLa), phosphagen (W), glycolytic (W), oxidative (W), and total energy demands (W) were analyzed. The contribution of the oxidative energy system was higher than that of the phosphagen or glycolytic energy system (65.9 ± 12% vs. 29.5 ± 11.1% or 4.6 ± 3.3%, both < 0.001). The contributions of the total energy demands and oxidative system in older adults were significantly lower than those in adults and adolescents (72.1 ± 28 kJ, = 0.028; 70.3 ± 24.1 kJ, = 0.024, respectively). The oxidative energy system was predominantly used for exergames applied in the current study. In addition, total metabolic work in older adults was lower than that in adolescents and adults. This was due to a decrease in the oxidative energy system. For future studies, quantification of intensity and volume is needed to optimize exergames. Such an approach plays a crucial role in encouraging physical activity in limited spaces.
外游戏已被推荐为增加体育锻炼健康益处的替代方法。然而，特定年龄组的外游戏的能量系统贡献（磷酸原、糖酵解和氧化）仍不清楚。本研究的目的是调查在特定年龄组的外游戏中三种能量系统和代谢特征的贡献。74 名健康男性和女性参加了这项研究（老年人，n=26：年龄 75.4±4.4 岁，体重 59.4±8.7kg，身高 157.2±8.6cm；成年人，n=24：年龄 27.8±3.3 岁，体重 73.4±17.8kg，身高 170.9±11.9cm；青少年，n=24：年龄 14±0.8 岁，体重 71.3±11.5kg，身高 173.3±5.2cm）。为了评估不同能量系统的需求，所有参与者都参与了名为“Action-Racing”的外游戏。外游戏方案包括站立、坐下、停止、跳跃和摆臂等全身运动。在进行外游戏时，分析了平均心率（HR）、最大心率（HR）、平均耗氧量（VO）、最大耗氧量（VO）、最大乳酸（Peak La）、乳酸差（ΔLa）、磷酸原（W）、糖酵解（W）、氧化（W）和总能量需求（W）。氧化能系统的贡献高于磷酸原或糖酵解能系统（65.9±12%比 29.5±11.1%或 4.6±3.3%，均 <0.001）。老年人的总能量需求和氧化系统的贡献明显低于成年人和青少年（72.1±28kJ，=0.028；70.3±24.1kJ，=0.024）。在当前研究中，外游戏主要使用氧化能系统。此外，老年人的总代谢工作量低于青少年和成年人。这是由于氧化能系统的减少。未来的研究需要量化强度和容量，以优化外游戏。这种方法在外游戏中起着至关重要的作用，可鼓励在有限的空间内进行身体活动。
