游泳消耗多少热量？

While swimming, your body burns 3.5 METs (223 calories per hour) treading water at a moderate effort; 8.3 METs (528 calories per hour) for a medium-speed, vigorous effort crawl; and 13.8 METs (878 calories per hour) for butterfly stroke. (These estimates are for a 140-pound adult.) https://www.shape.com/fitness/cardio/how-many-calories-does-swimming-burn

感觉跟Garmin手表给出的数值差不多。我做运动的体会就是，绝大多数运动消耗的热量很少能超过自己1小时费力（比赛）跑步消耗的热量。
