EXERCISING CAN be tedious(乏味的，单调的). Video games are fun. What if(如果……会怎样？) you could combine them? Playing games while wearing a virtual-reality (VR) headset, with a motion-sensitive controller in each hand, can be taxing.(戴着VR头盔、双手持控制器玩游戏可能很费力。) “Pistol Whip” makes you step from side to side and squat frequently as you gun down foes(敌人（复数）) and dodge(躲避，闪开) bullets. “The Thrill of the Fight” is a virtual boxing game that works up a real sweat(出一身大汗). In “Supernatural” and “Beat Saber” you punch and slice moving targets in time to(合着节拍，及时) pumping music. But does any of this count as proper exercise?
锻炼可能很乏味。电子游戏则很有趣。如果能把两者结合起来呢？戴着虚拟现实（VR）头盔、双手各持一个动作感应控制器玩游戏，可能会让人筋疲力尽。《手枪鞭击》让你在击倒敌人、躲避子弹时频繁地左右移动和下蹲。《搏击快感》是一款虚拟拳击游戏，能让你真正出一身汗。在《超自然》和《节奏光剑》中，你要随着动感音乐出拳和劈砍移动的目标。但这些能算作真正的锻炼吗？
The answer is yes, though with caveats(警告，注意事项). One way to evaluate VR exercise is a measure called metabolic equivalent of task (MET). Someone at rest expends(消耗（能量）) about one MET. Walking is three METs. Playing football, ten. Anything over six METs is considered “vigorous(剧烈的，有力的)” exercise. Researchers at San Francisco State University determined that playing “The Thrill of the Fight” (which is, in fact, exhausting) was a 9.3 MET activity.(旧金山州立大学的研究人员确定，玩《搏击快感》是9.3 MET的活动。) Other work, published in JMIR Serious Games, found the “Flow” and “Boxing” modes in “Supernatural” also counted as(被视为，算作) vigorous exercise, at around eight METs.
答案是肯定的，不过有一些注意事项。评估 VR 锻炼的一种方法是称为任务代谢当量（MET）的指标。静坐的人大约消耗 1 MET。步行是 3 MET。踢足球是 10 MET。任何超过 6 MET 的活动都被视为“剧烈”运动。旧金山州立大学的研究人员确定，玩《搏击快感》（实际上确实令人精疲力竭）是 9.3 MET 的活动。发表在《JMIR 严肃游戏》上的另一项研究发现，《超自然》中的“流动”和“拳击”模式也属于剧烈运动，约为 8 MET。
In yet another study, published in Games for Health Journal in 2024, participants played a sedentary video game, two VR games, and walked on a treadmill, each for ten minutes, while having their oxygen consumption measured.(在2024年发表于《游戏促进健康杂志》的另一项研究中，参与者玩久坐游戏、两款VR游戏并在跑步机上行走，各十分钟，同时测量耗氧量。) Playing “The Thrill of the Fight” was comparable in aerobic intensity to walking on a treadmill(跑步机), and raised heart rates by a similar amount.
在另一项于2024年发表在《游戏促进健康杂志》上的研究中，参与者玩了一款久坐型电子游戏、两款 VR 游戏，并在跑步机上行走，每项活动各进行十分钟，同时测量他们的耗氧量。玩《搏击快感》在有氧强度上与在跑步机上行走相当，并且使心率升高的幅度也相似。
