Exergames can replace sedentary time spent on computer gaming with physical activity. Previous research has found exergaming to elicit light-to-moderate exercise intensity. Our primary aim was to examine the exercise intensity of a newly developed biking exergame.
Eight males (23.9±0.6 years) played the exergame (PLAY) and walked (WALK) on three separate occasions, with the condition counterbalanced and in random sequence within each day. They were asked to PLAY and WALK for a minimum of 15 min and then continue for as long as they wanted. We measured heart rate (HR), activity duration, caloric expenditure and subject-rated exertion and enjoyment (based on 0-10 Visual Analogue Scale, VAS). We used an average of each outcome variable across the 3 days in the analysis.
The average intensity during PLAY (73%±10% of HR) was significantly higher than that during WALK (57%±7% of HR, p=0.01). Participants spent 12.5±5.3 min at 80%-89% of HR and 5.5±4.6 min at ≥90% of HR during PLAY, whereas intensity during WALK was ≤72% of HR. The duration of PLAY was 44.3±0.7 min and of WALK 17.0±0.7 min (p=0.01). The relative energy expenditure during PLAY was 7.6±0.7 kcal/min and during WALK 6.2±0.3 kcal/min (p<0.01). The enjoyment of PLAY (VAS 8.7±0.1) was higher than that of WALK (VAS 3.9±1.8, p=0.01).
Exergaming can be an innovative way of enjoyable high-intensity training.
运动游戏可以用体育活动取代花在电脑游戏上的久坐时间。先前的研究发现运动游戏能引发轻度至中度的运动强度。我们的主要目的是研究一款新开发的骑行运动游戏的运动强度。
八名男性（23.9±0.6岁）在三个不同的时间段分别进行运动游戏（PLAY）和步行（WALK），每天的条件相互平衡且顺序随机。要求他们进行运动游戏和步行至少15分钟，然后根据自己的意愿继续进行。我们测量了心率（HR）、活动时长、热量消耗以及受试者的主观用力程度和愉悦感（基于0-10视觉模拟量表，VAS）。在分析中，我们使用了三天内每个结果变量的平均值。
运动游戏期间的平均强度（心率的73%±10%）显著高于步行期间（心率的57%±7%，p=0.01）。在运动游戏期间，参与者心率在80%-89%的时间为12.5±5.3分钟，心率≥90%的时间为5.5±4.6分钟，而步行期间的强度≤心率的72%。运动游戏的时长为44.3±0.7分钟，步行的时长为17.0±0.7分钟（p=0.01）。运动游戏期间的相对能量消耗为7.6±0.7千卡/分钟，步行期间为6.2±0.3千卡/分钟（p<0.01）。运动游戏的愉悦感（VAS 8.7±0.1）高于步行（VAS 3.9±1.8，p=0.01）。
运动游戏可以成为一种有趣的高强度训练的创新方式。
