In recent years, organised and competitive video gaming, esports, has gained enormous popularity in many parts of the world, contributing to the growing professionalisation of this sports branch. To become or remain a professional esports player, individuals practice video gaming for several hours a day while remaining in a sitting posture which may not only lead to a decrease in training quality in the short term (eg, due to cognitive fatigue) but also put them at a higher risk for negative health events in the long-term (eg, overuse injuries). Thus, interrupting periods of prolonged video gaming in a sitting posture with acute physical exercise is strongly recommended for esports players even though the optimal dosage of acute physical exercise breaks remains unclear. To address this gap, we propose in this viewpoint that traditional concepts of exercise prescription and dosage determination using the variables frequency, intensity, time (also referred to as duration) and type of physical exercise (ie, abbreviated with the acronym FITT) should be complemented by the variable density which characterises the timing of consecutive bouts of acute physical exercise during an esports session.
近年来，有组织的竞技类电子游戏，即电子竞技，在世界许多地区广受欢迎，推动了这一体育分支的日益职业化。为了成为或保持一名职业电子竞技选手，人们每天要坐着练习几个小时的电子游戏，这不仅可能在短期内导致训练质量下降（例如，由于认知疲劳），而且从长期来看，还会使他们面临更高的负面健康事件风险（例如，过度使用损伤）。因此，尽管急性体育锻炼休息的最佳剂量尚不清楚，但强烈建议电子竞技选手用急性体育锻炼来打断长时间坐着玩电子游戏的时段。为了填补这一空白，我们在本观点文章中提出，使用频率、强度、时间（也称为持续时间）和体育锻炼类型等变量（即简称为FITT）来确定运动处方和剂量的传统概念，应补充以密度变量，该变量表征了电子竞技时段中连续急性体育锻炼回合的时间安排。
